Knee Instability — Recurrent Subluxation and Patellar Instability

The knee gives way underneath you. The ligaments no longer hold the joint where it belongs.

Instability is a separate rating from range of motion, and that single fact is worth thousands of dollars a year to veterans who are never told it. The VA General Counsel has confirmed that a knee with instability under Code 5257 and arthritis with limitation of motion under Codes 5003/5260/5261 can carry both ratings at once, because they compensate different functional losses and therefore do not violate the anti-pyramiding rule at 38 CFR §4.14. Most veterans are rated for one and never learn they qualified for two.

Before Anything Gets Rated

What The VA Is Actually Looking For — And What Service Connection Really Means

Before the VA ever opens the rating schedule, it asks one question: is this disability the government’s responsibility? That is what “service connection” means. It is not a diagnosis, it is not sympathy, and it is not a reward for having served. It is a legal finding that a current, diagnosed disability is linked to something that happened to you in uniform. Percentages come later. If service connection is not established, there is nothing to rate and the claim is denied — no matter how bad the knee instability is.

A veteran reviewing a VA decision letter at his desk, hands gripping the document

The three elements the VA must find. All three. Every time.

These come out of Caluza v. Brown and Shedden v. Principi, and they are the checklist a rating officer works through on your file. Miss one and the claim fails on that element alone.

1

A current, diagnosed disability

A doctor has to have written a diagnosis in a medical record — knee instability. Symptoms by themselves are not a disability the VA can rate. Saunders v. Wilkie held that pain causing functional impairment can be a disability, but you still need a clinician to document it as diagnosed and impairing. The diagnosis must exist now, during the claim period — not only years ago.

2

An in-service event, injury, illness or aggravation

Something in service had to have happened — an injury, an exposure, a documented sick call, or steady wear over a career. It does not have to be one dramatic moment and it does not have to be spelled out in your service treatment records: buddy statements, unit records, performance evaluations and your own competent lay testimony can establish it.

3

A medical nexus linking the two

A qualified medical opinion that says the current diagnosis is at least as likely as not related to the in-service event. That phrase matters: at least as likely as not means 50 percent or better. Under 38 C.F.R. §3.102, when the evidence is evenly balanced, the benefit of the doubt goes to you and the claim must be granted.

The five ways service connection is established

Most veterans only know the first one. The other routes are lower-effort paths to the same grant — and the secondary route is the one most often left on the table.

Direct — 38 C.F.R. §3.303(a)

The injury or disease began in service and never went away. The classic route: three elements, one nexus opinion.

Chronicity and continuity — §3.303(b)

A chronic condition shown in service, plus continuity of the same symptoms from separation to now, can establish the link without a formal nexus opinion. Your own testimony about symptoms you can observe is competent evidence.

Presumptive — §3.307 and §3.309

Certain chronic diseases are presumed service connected if they manifest to a compensable degree within a set window after separation. You do not have to prove causation at all.

Secondary — §3.310(a) and (b)

A disability proximately due to, or aggravated by, an already service-connected condition is itself service connected. This is how the downstream conditions knee instability sets off get on the rating sheet.

Aggravation of a pre-service condition — §3.306

If you entered service with a condition and service made it permanently worse, the increase is compensable. The VA must rebut the presumption of soundness by clear and unmistakable evidence — a bar it frequently fails to meet.

VA medical care — 38 U.S.C. §1151

An additional disability caused by VA treatment, surgery, or a failure to diagnose is compensated as if it were service connected.

The bottom line — there is no way around this

No diagnosis, no rating. It has to be chronic. It has to cause impairment.

Without a diagnosis, the VA will not rate your claim.

The rating schedule is a list of diagnosed conditions and the codes attached to them. If no clinician has put a name on your condition in a medical record, there is no code to assign. Symptoms reported to a claims examiner are not a diagnosis. Get in front of a doctor and get it written down.

The condition must be chronic.

Chronic means persistent and ongoing — not something that resolved decades ago. The VA compensates a disability you carry today, which is why a documented, continuing treatment history matters more than the single worst day you ever had.

It must cause actual impairment.

Under 38 C.F.R. §4.1 and §4.10, VA compensation exists to pay for reduction in earning capacity. A diagnosis that costs you nothing gets a zero percent rating. The function you have lost is what converts a diagnosis into a percentage.

What this means for you before you file: get the diagnosis in writing, get the treatment history documented so the chronicity is undeniable, and describe the impairment in functional terms — what you can no longer do, and what it costs you at work and at home. Everything on the rest of this page is built on top of those three things.

The Percentages

Rating Schedule — Knee Instability, Diagnostic Code 5257

Reproduced verbatim from 38 CFR §4.71a. Code 5257 now carries two separate criteria sets — one for ligament instability and one for patellar instability. Note on the 2021 amendment: the criteria for Code 5257 were rewritten effective February 7, 2021. If your claim was pending before that date, the VA must consider both the old and the new criteria and apply whichever is more favorable to you.

10%

Ligament instability. Sprain, incomplete ligament tear, or complete ligament tear (repaired, unrepaired, or failed repair) causing persistent instability, without a prescription from a medical provider for an assistive device (cane, crutches, walker) or bracing for ambulation.

20%

Ligament instability. Either (a) sprain, incomplete ligament tear, or repaired complete ligament tear causing persistent instability, and a medical provider prescribes a brace and/or an assistive device for ambulation; or (b) unrepaired or failed repair of a complete ligament tear causing persistent instability, and a medical provider prescribes either an assistive device or bracing.

30%

Ligament instability. Unrepaired or failed repair of a complete ligament tear causing persistent instability, and a medical provider prescribes both an assistive device (cane, crutches, walker) and bracing for ambulation.

10%

Patellar instability. A diagnosed condition involving the patellofemoral complex with recurrent instability (with or without a history of surgical repair) that does not require a prescription for a brace, cane, or walker.

20%

Patellar instability. A diagnosed condition involving the patellofemoral complex with recurrent instability after surgical repair that requires a prescription for one of the following: a brace, cane, or walker.

30%

Patellar instability. A diagnosed condition involving the patellofemoral complex with recurrent instability after surgical repair that requires a prescription for a brace and either a cane or a walker.

Note

The patellofemoral complex consists of the quadriceps tendon, the patella, and the patellar tendon. A surgical procedure that does not repair one or more patellofemoral components contributing to the instability does not qualify as surgical repair.

Service Connection

Advice from the Advocate

Medical illustration of a knee joint cutaway showing a torn anterior cruciate ligament with frayed fibers between the femur and tibia
A stretched or torn cruciate ligament does not heal back to its original length. Once the restraint is gone the tibia slides on the femur and the knee gives way — the mechanical failure Diagnostic Code 5257 exists to compensate.

The advocate's notes on causation — Knee Instability

The separate arguments that decide this code: where the VA will attack, the regulation that answers it, and the evidence that closes the gap.

A veterans disability advocate seated in a law office, ready to explain why instability is rated separately from range of motion
  1. 1The in-service sprain that was never followed up is still the injury — §3.303(a) and §3.303(d)

    The VA will point at a single sick-call entry reading "knee sprain, ice, quarters, RTD" and argue it resolved. It did not. 38 CFR §3.303(a) requires service connection for any disability resulting from injury incurred in the line of duty, and §3.303(d) expressly allows service connection when the disease is first diagnosed after discharge if the evidence establishes it was incurred in service. A torn or stretched ligament does not heal back to its original length. The sprain in 1998 and the failing ACL today are the same injury on a longer timeline.

  2. 2Continuity of symptoms carries it even with a thin record — §3.303(b) and Buchanan v. Nicholson

    If the record is thin, 38 CFR §3.303(b) allows service connection on continuity of symptomatology, and the Federal Circuit held in Buchanan v. Nicholson, 451 F.3d 1331 (Fed. Cir. 2006) that the absence of contemporaneous medical records cannot be the sole basis for rejecting competent lay evidence. You are competent to say the knee has given way since Fort Bragg. Your spouse is competent to say she has watched it happen. Buddy statements from the men who caught you are evidence, not anecdote.

  3. 3Combat and field conditions relax the proof standard — 38 U.S.C. §1154(b)

    If the knee went out during combat service, 38 U.S.C. §1154(b) and 38 CFR §3.304(d) require the VA to accept lay or other evidence of the injury as sufficient proof if it is consistent with the circumstances, conditions, or hardships of that service — even with no official record — and the VA can only rebut it with clear and convincing evidence. Nobody filed a sick-call slip during a fire mission. The statute exists precisely for that.

  4. 4Instability plus arthritis is two ratings, not one — §4.14 does not bar it

    The VA routinely folds instability into the range-of-motion rating and calls the second one pyramiding. It is not. 38 CFR §4.14 only bars rating the same disability under different diagnoses; instability and limitation of motion are different functional losses, and VA General Counsel precedent opinions confirm that a knee with both can be separately rated. If your decision shows one code where two apply, that is a rating error to be raised — not a settled fact.

  5. 5The other knee, the hip, and the back are all secondary — §3.310(a) and §3.310(b)

    A knee that buckles changes how you walk, and the body pays for that everywhere else. 38 CFR §3.310(a) grants service connection for any disability proximately due to or the result of a service-connected condition, and §3.310(b) separately grants it for aggravation of a nonservice-connected condition. The opposite knee absorbing the load, the hip taking the altered gait, and the lumbar spine compensating for the limp are all claimable — and each is a rating of its own.

Exposure & Aggravation

How Knee Instability Happens In Service — And How It Gets Worse

How veterans pick this up in uniform — Knee Instability

Knee Instability rarely announces itself with one dramatic moment. It is built by what service asked of your body over months and years — and once it is service-connected, it is compensated for how it keeps getting worse, not for how it started. Below is how veterans pick this up in uniform, and who is most prone to it.

  • Airborne and air-assault landings — the knee takes a rotational load on impact and the ACL is the first thing to go
  • Ruck marches on broken ground with 60 to 100 pounds driving through the joint
  • Jumping down from a truck bed, a HMMWV, an aircraft ramp, or a fighting position, day after day
  • Combatives, PT, and unit sports played on concrete and hardpan
  • Pivoting under load in boots that give the ankle no play, so the rotation goes straight into the knee
  • A documented knee sprain treated on sick call with an Ace wrap, ibuprofen, and a return to full duty
  • Shipboard ladders and hatch coamings taken at speed in a seaway
  • Kneeling and squatting in a turret, a cockpit, an engine bay, or a hull for years

Who is most prone to it

Infantry, airborne, air assault, cavalry scouts, combat engineers, military police, artillery crew, aircraft and vehicle mechanics, Seabees, corpsmen and medics carrying aid bags, and anyone whose PT test was run in boots on pavement.

The Symptoms

What Knee Instability Actually Feels Like

  • The knee buckles or gives way — on stairs, on uneven ground, stepping off a curb
  • A feeling that the joint is about to shift out from under you when you pivot
  • The kneecap slides sideways, catches, or fully dislocates
  • You wear a brace, sleeve, or hinged support to get through the day
  • You use a cane, crutch, or walker because you do not trust the leg
  • Swelling after the knee gives out, then a period of guarding it
  • You have fallen because of it — sometimes more than once
  • You avoid ladders, ramps, and crowds because a shove would drop you

How this one is rated

Since the February 7, 2021 revision, instability is no longer rated on the old slight / moderate / severe wording. It is rated on what is torn, whether it was repaired, and what a medical provider has prescribed you to walk with. A brace prescription and an assistive-device prescription are now rating criteria, not background detail.

What you are measured against

Anterior and posterior laxity are tested with the Lachman and drawer tests; medial and lateral laxity with varus and valgus stress. Patellar instability is tested with apprehension and glide.

Each One On Its Own Page

Secondary Conditions — Aggravated or Caused by a Current Service-Connected Condition

Under 38 CFR §3.310(a), a disability that is proximately due to a service-connected condition is service-connected in its own right — and under §3.310(b), so is any additional disability caused when a service-connected condition aggravates a problem you already had. Each condition below is a separate evaluation with its own diagnostic code and its own percentage. They do not fold into the knee instability rating — they stack on top of it. A veteran who claims only the primary condition leaves these ratings on the table.

The other knee, the hip, and the back

A knee that gives way changes how you walk, and the body pays for that everywhere else. The opposite knee absorbs the load, the hip takes the altered gait, and the lumbar spine compensates for the limp. Under §3.310(a) each of those is separately claimable as secondary to the service-connected knee — and each is a rating of its own. Report the new aches in the good leg and the back; they are evidence, not complaints.

Falls and the injuries they cause

Every fall from a buckling knee is a separately documentable event — a fracture, a concussion, a torn rotator cuff — that flows directly from the service-connected instability under §3.310(a). The falls also drive the severity finding the schedule requires. Keep a dated list of every fall and near-fall and bring it to the exam.

The work the knee ends

A knee you cannot trust makes ladders, scaffolding, uneven ground, and standing shifts impossible. For veterans in the trades, in warehousing, in any role on their feet, an unstable knee is a straight line to TDIU under §4.16 — the disability that makes you unemployable. Document every work task the knee has taken away from you.

Knee Instability — Recurrent Subluxation and Patellar Instability

Instability is a separate rating from range of motion, and that single fact is worth thousands of dollars a year to veterans who are never told it. The VA General Counsel has confirmed that a knee with instability under Code 5257 and arthritis with limitation of motion under Codes 5003/5260/5261 can carry both ratings at once, because they compensate different functional losses and therefore do not violate the anti-pyramiding rule at 38 CFR §4.14. Most veterans are rated for one and never learn they qualified for two.

Limitation of Range of Motion of the Knee — Flexion and Extension

Range of motion in the knee is two separate measurements, and each one is its own diagnostic code. Flexion is the bend, rated under Diagnostic Code 5260; extension is the straighten, rated under Diagnostic Code 5261. Flexion tops out at 30%, extension climbs to 50%, and — this is the part veterans lose money on — 38 CFR §4.14 lets both be rated separately on the same knee, because they compensate opposite movements. Every percentage under both codes is a number on a goniometer, which means the rating is won or lost on how and when the measurement was taken. 38 CFR §4.59 requires that painful motion be treated as at least the minimum compensable rating, and DeLuca v. Brown, 8 Vet. App. 202 (1995) requires the examiner to account for additional loss during flare-ups and after repeated use. A single good-day number, taken cold and seated, is not a lawful rating picture.

Semilunar Cartilage — Dislocated Meniscus and Meniscectomy Residuals

The menisci are two crescents of fibrocartilage sitting on the tibial plateau, and they are the reason your knee survives being landed on. Once one is torn and displaced, the joint mechanically catches. The VA rates this separately from motion and separately from instability, under two codes: 5258 for a dislocated meniscus with locking, pain, and effusion, and 5259 for symptomatic residuals after the cartilage has been removed. Both are frequently swallowed into a single motion rating that pays less.

Degenerative and Post-Traumatic Arthritis of the Knee

Arthritis is the knee code that quietly pays when nothing else does. Under 38 CFR §4.71a, Code 5003, degenerative arthritis established by X-ray is rated on limitation of motion — but when the limitation is noncompensable, the regulation still assigns 10 percent for each major joint affected by painful or limited motion. Code 5010 applies the same rules to traumatic arthritis. And §4.59 independently entitles an actually painful joint to the minimum compensable rating. That is three separate routes to a payment on a knee whose degrees look "normal."

Ankylosis of the Knee

Ankylosis is the end of the road for a joint: bony or fibrous fusion, no usable motion in any direction. It is the highest-paying knee code, running from 30% to 60%, and — counter-intuitively — the straighter the fusion, the lower the rating. A knee fused at full extension is still a leg you can stand and walk on. A knee fused at 45 degrees or more is a leg you drag. The angle is the whole rating.

Impairment of the Tibia and Fibula, and Medial Tibial Stress Syndrome

Code 5262 covers the two long bones between the knee and the ankle, and since the February 7, 2021 revision it does two very different jobs. The first is structural failure of the bone — a fracture that healed crooked (malunion) or never healed at all (nonunion). The second is medial tibial stress syndrome, which the schedule added by name — the condition every veteran knows as shin splints, which for decades had no code of its own and was routinely denied because of it.

The C&P Exam

What To Expect At The Knee Instability Exam

This is the encounter your rating is built on. The examiner has a checklist and a limited window — what follows is exactly what happens in that room, so none of it surprises you.

Clinical Section — What To Expect at the Exam

What to Expect at Your Knee Instability C&P Examination

Diagnostic Code 5257 — this exam is about ligaments, not degrees

This is the exam veterans most often lose on paperwork rather than pathology. Since **February 7, 2021** your percentage turns on three things: **what is torn**, **whether it was surgically repaired**, and **what a medical provider has prescribed you to walk with**. An examiner who tests your motion beautifully and never opens the stability section has produced an inadequate exam for this code.

01In The Room

What happens during the exam

The tests and maneuvers for this condition

  • Lachman test, both knees
  • Anterior and posterior drawer
  • Valgus and varus stress at 0° and 30°
  • Patellar apprehension and glide
  • Pivot shift, if tolerated
  • Review of MRI and any operative reports
  • Bilateral thigh circumference for atrophy
  • Gait observation over a walked distance, not just across the room

What gets measured, and to what number

Anterior and posterior laxity

Lachman test and anterior/posterior drawer, performed on both knees so the good one is the baseline.

Medial and lateral laxity

Valgus and varus stress at 0 and at 30 degrees of flexion, testing the MCL and LCL.

Patellar tracking

Apprehension test and patellar glide, documenting subluxation and any history of frank dislocation.

Assistive devices in use

Whether a brace, cane, crutches, or walker is used — and critically, whether it was prescribed and by whom.

Quadriceps atrophy

Thigh circumference measured bilaterally at a fixed distance above the patella. Atrophy is objective proof you have been guarding the leg.

02Orientation

What to expect during this exam

What makes this exam different from every other C&P exam

1Your brace prescription is now a rating criterion

The difference between 10% and 20% can be a single line in your chart from a provider prescribing a brace or a cane. A brace you bought yourself at a drugstore does not meet the wording. Get it prescribed and get it in the record before the exam.

2Repaired versus unrepaired changes the ceiling

A complete ligament tear that was never repaired, or where the repair failed, is the only path to 30%. Operative reports and post-op imaging matter more here than the examiner’s hands do.

3Patellar instability is rated on its own wording

If your kneecap is what dislocates, the patellofemoral criteria apply, and a surgery that did not repair the quadriceps tendon, patella, or patellar tendon does not count as surgical repair under the note to the code.

See it before you sit in the room

03Preparation

Know your symptoms and secondary factors

What the report must actually say about knee instability — dc 5257

  • "It gives way" — use those words, and say how many times in the last month.
  • "My doctor prescribed this brace" — and name the provider and the date.
  • "I have fallen because of it" — describe the fall, the injury, and whether anyone saw it.
  • "I use a cane on bad days" — frequency matters; do not round it down to be polite.
  • "The ligament was torn and never repaired" — or repaired and it failed. Say which.
  • "I do not trust it on stairs or uneven ground."

Pain level, frequency, lost work and functional loss — how to say them

Illustration of a person whose knee buckles as they step down a staircase, losing their balance

Say "it gives way" — use those three words

The examiner is trained to record what you say. "My knee hurts" gets logged as pain and routed to a range-of-motion rating. "It gives way" is the phrase that triggers the instability code. Say it plainly, and say how many times it has happened in the last month — buckling on stairs, stepping off a curb, pivoting to turn.

Count the episodes out loud. "Three times last week" is a finding; "sometimes" is not.

"It gives way underneath me — three or four times this month, usually on stairs or uneven ground."

Illustration of a kneecap sliding sideways out of its groove, depicting patellar dislocation

Describe the kneecap sliding or dislocating

If it is your kneecap that shifts sideways, catches, or fully pops out, that is patellar instability — a separate criteria set under Code 5257 with its own path to 20% and 30%. The examiner has to know it is the kneecap, not the whole joint, so the right criteria are applied. Say whether it has ever fully dislocated and had to be put back.

Mention any surgery on the kneecap and whether it fixed the sliding or not.

"My kneecap slides out to the side and catches. Twice it dislocated completely and I had to straighten the leg to get it back in."

Illustration of a person wearing a hinged knee brace and gripping a walking cane while moving forward

Name the brace and cane your doctor prescribed

Since February 7, 2021, a prescription for a brace or an assistive device is a rating criterion — it is the line between 10% and 20%, and between 20% and 30%. A brace you bought at the drugstore does not meet the wording. Name the provider who prescribed it and the date, so the examiner records it as prescribed, not self-supplied.

Bring the actual brace and cane to the exam and the prescription paperwork with them.

"Dr. Reyes prescribed this hinged brace and a cane in March. I cannot walk any distance without both."

Illustration of a person mid-fall clutching their knee in pain on uneven outdoor ground

Report every fall the knee has caused

A knee that buckles drops you, and each fall is a separately documentable injury — a fractured wrist, a head strike, a torn shoulder — that traces straight back to the service-connected knee. Falls also prove the severity the rating criteria measure. Do not minimize them to seem tougher; describe the fall, the injury, and whether anyone saw it.

Include near-falls and the grab-the-railing moments too — they show how unsafe the joint is.

"It buckled and I went down hard on the driveway last month — my wife saw it and had to help me up."

Secondary conditions to raise in the same appointment

The other knee, the hip, and the back

A knee that gives way changes how you walk, and the body pays for that everywhere else. The opposite knee absorbs the load, the hip takes the altered gait, and the lumbar spine compensates for the limp. Under §3.310(a) each of those is separately claimable as secondary to the service-connected knee — and each is a rating of its own. Report the new aches in the good leg and the back; they are evidence, not complaints.

Falls and the injuries they cause

Every fall from a buckling knee is a separately documentable event — a fracture, a concussion, a torn rotator cuff — that flows directly from the service-connected instability under §3.310(a). The falls also drive the severity finding the schedule requires. Keep a dated list of every fall and near-fall and bring it to the exam.

The work the knee ends

A knee you cannot trust makes ladders, scaffolding, uneven ground, and standing shifts impossible. For veterans in the trades, in warehousing, in any role on their feet, an unstable knee is a straight line to TDIU under §4.16 — the disability that makes you unemployable. Document every work task the knee has taken away from you.

How to prepare for this specific exam

  • Bring the brace and the cane you actually use — do not leave them in the car.
  • Bring or request the prescription documentation for every device.
  • Bring the MRI report and the operative report if you had surgery.
  • Write down every episode of buckling in the last 90 days, with dates.
  • Bring a buddy statement or a spouse statement describing the knee giving out.
  • Do not warm the knee up before the exam so it performs better than it lives.

04The Protocol

What procedures are required during the exam

These are not courtesies. Each comes out of the regulation or out of binding case law. Take this list in with you and tick them off as they happen.

01Lachman test — the primary ACL sign

38 C.F.R. §4.71a

The examiner holds the knee at roughly 20 to 30 degrees of flexion and pulls the tibia forward against a stabilized femur. Excess forward travel with a soft endpoint is anterior cruciate laxity — the core finding for Code 5257. It must be performed on both knees so the good one is the baseline.

The Lachman is the most sensitive test for ACL instability. A documented positive Lachman is the objective proof that puts you under the instability code rather than a bare range-of-motion rating.

Clinical illustration of the anterior and posterior drawer test on a knee bent to ninety degrees with the shin pushed and pulled
Fig. 02Anterior and posterior drawer

02Anterior and posterior drawer

38 C.F.R. §4.71a

With the knee bent to 90 degrees, the examiner pulls the shin forward (anterior drawer, for the ACL) and pushes it back (posterior drawer, for the PCL). Excess travel in either direction documents which cruciate ligament has failed.

The drawer tests corroborate the Lachman and separate ACL from PCL involvement — which matters because the schedule rates on what is torn and whether it was repaired.

Clinical illustration of the valgus and varus stress test with hands applying sideways force to a straightened knee
Fig. 03Valgus and varus stress

03Valgus and varus stress

38 C.F.R. §4.71a

The examiner applies sideways force to the knee at 0 and at 30 degrees of flexion — inward force (valgus) tests the MCL, outward force (varus) tests the LCL. Gapping on either side is collateral ligament laxity.

Collateral instability is rated under the same code and is routinely skipped. Documented valgus/varus laxity captures a functional loss the range-of-motion measurements miss entirely.

Clinical illustration of the patellar apprehension test with the examiner pushing the kneecap sideways to assess tracking
Fig. 04Patellar apprehension and glide

04Patellar apprehension and glide

38 C.F.R. §4.71a

The examiner pushes the kneecap sideways and watches for the flinch of apprehension, then measures how far it glides. This documents patellar instability — the separate criteria set under Code 5257 for a kneecap that subluxes or dislocates.

If your kneecap is what gives way, this is the test that puts you under the patellar-instability criteria instead of the ligament criteria. Without it, patellar instability goes unrated.

05Review of MRI and operative reports

38 C.F.R. §4.71a

The examiner must read your MRI and any operative reports, not just lay hands on the joint. The imaging shows whether a complete tear exists and whether a repair failed — and a failed or unrepaired complete tear is the only path to the 30% level.

The paper record often proves more than the exam-day hands do. A complete tear on MRI with a failed repair in the operative note is what unlocks the top rating the wording allows.

05The Standard

What makes an exam adequate

Read your exam report against these. An exam that fails the standard is legally inadequate, and an inadequate exam is something you challenge rather than accept.

01

The range of motion has to be MEASURED, not estimated

38 CFR §4.46 states that the use of a goniometer in the measurement of limitation of motion is indispensable in examinations conducted within the Department of Veterans Affairs. An examiner who eyeballs your bend and writes a number has not complied with the regulation. This is the most common defect in a spine exam and it is the easiest one to spot from the chair.

02

Joints must be tested in every required condition

Under Correia v. McDonald, a joint examination for pain must, wherever possible, record active motion, passive motion, motion in weight-bearing and motion in non-weight-bearing — and where relevant, the range of the opposite undamaged joint. An exam that records one set of numbers and stops is incomplete on its face, and that incompleteness is grounds to challenge it.

03

Flare-ups have to be addressed, not dodged

Under Sharp v. Shulkin, when a veteran describes flare-ups, the examiner is obligated to estimate the additional loss of motion during a flare based on all the available evidence — including your own account of it. "I cannot opine without resorting to mere speculation" is not automatically acceptable; the examiner has to have actually sought the information first and explained why an estimate is impossible.

04

Repetitive use and functional loss must be factored in

Sections 4.40 and 4.45, and the DeLuca line of cases, require that pain, weakness, fatigability, incoordination and lack of endurance after repeated use be considered — and expressed in additional degrees of lost motion where that is feasible. Your rating is supposed to reflect what you can do on the fifth repetition and on a bad day, not just the first careful bend of the morning.

05

Neurological findings must be separately documented

Note (1) to the General Rating Formula requires that any associated objective neurologic abnormality be evaluated separately under an appropriate diagnostic code. If your leg symptoms were mentioned in the narrative but never tested and never assigned, the exam did not do what the schedule requires of it.

06

The examiner must review the record when the question requires it

Where a medical opinion on cause, aggravation or a secondary relationship was requested, the examiner is expected to review the relevant evidence and give a reasoned explanation. A bare conclusion — "less likely than not related to service" with no reasoning attached — carries little weight, and an opinion with no rationale is challengeable.

07

The examiner has to be qualified for the body system

The VA may use its own clinicians or a contract vendor. Either way, the examiner is expected to have the competence to evaluate the system being examined. If a spinal exam with a neurological component was performed by someone who never tested a reflex, that is a problem worth raising.

08

The exam has to be CURRENT

A rating is supposed to reflect your condition now. An exam performed before a documented worsening, or years before the decision, may not support the current evaluation — and you can request a new one on that basis.

06Afterward

What happens after your exam is complete

The examiner writes the report and submits it, it is reviewed for completeness, and only then does the claim move toward a rating decision. Here is what actually controls the clock.

01

The examiner writes and submits the report

Days 1–5 after the exam

The examiner compiles the history, the physical findings, the measurements and any testing into the questionnaire, adds any requested medical opinion, and submits it. Contract vendors typically have a turnaround requirement measured in days, not weeks.

Nothing about your claim moves while this is happening, and nothing you do speeds it up. What matters is that the report is written from notes taken in the room — which is exactly why what you said, and how the examiner recorded it, is already locked in by the time you get to your car. Request your copy now rather than later.

02

Quality review — and the request for clarification

Days 3–30

The report is reviewed for completeness. If it is internally inconsistent, missing a required field or missing the opinion the VA asked for, it goes back for correction or a second opinion. This is the single most common cause of a claim appearing to stall after the exam.

Understand what a finished exam actually means: it means the appointment happened, not that your claim is ready for a decision. If the reviewer finds a blank range-of-motion field, an opinion that does not answer the question that was asked, or findings that contradict each other, the file goes back out for more information. That is a normal quality control step, not a rejection of your claim, and it is not a sign that you did something wrong — but it does add weeks, and it is the reason so much of what you read online sounds like the system is broken.

03

Your status tracker moves backward — and it is usually not bad news

Any time after the exam

The online tracker shows eight steps. Veterans watch it reach step 7 or 8, then find it back at step 3 or 4 a week later. That regression almost always means one thing: the file went back for additional information, most often a returned or clarified exam.

This is the number one thing veterans panic about, and it is misread constantly. The tracker is not a countdown — it is a location marker. When the VA decides it needs one more piece of evidence, a corrected exam, a clarifying medical opinion or an outstanding record, the claim is routed back to the evidence gathering step and the bar redraws itself where the file physically is. It does not mean a denial. It does not mean your case was thrown out or restarted. It does not erase anything already in the file, and it does not change your effective date. What it does mean is that something in the record was not good enough to decide on yet — which is worth knowing, because if the weak link is the exam, this is the window where a corrective statement or a private opinion from your own doctor does the most good.

Evidence gathering closes

Varies

Before anyone rates your claim, the file has to be built. This is the stretch where the Regional Office pulls together everything the decision will rest on: your service treatment records, your VA medical records, any federal records, the C&P exam report, and any private records it has requested on your behalf. The claim sits here until the VA is satisfied the record is complete enough to decide — which is exactly why a status tracker can appear to stall or slide backward at this step. You are not powerless while it sits here. Anything you put into the file yourself lands the day you send it, and every relevant record you add now is one less thing the rater can later say was missing.

A VA request to a private provider is a letter that may or may not be answered, and the VA will wait on it for weeks before moving on — sometimes without ever getting a response. A record you walk in yourself, or upload through your claim, is in the file the day you send it. So do not sit and wait to be asked. If you know a treatment record, an imaging report, a surgical note or a buddy statement exists and it matters, send it now, with a VA Form 21-4138 statement that explains in plain words what the document is and what it shows. This is also the window where a corrective statement or a private medical opinion from your own doctor does the most good — before the rater has locked in a decision, not after. Once the evidence gathering step closes, the file goes to a rating specialist, and your chance to shape the record cheaply and quickly closes with it.

Rating decision and promulgation

Typically several weeks after the last piece of evidence lands

This is the stage where your evidence finally becomes a number. A rating specialist — not the examiner, and not a doctor — takes everything in the file and applies the rating schedule to it: the exam findings, your range-of-motion measurements, your lay statements, your private records and any medical opinions. They assign a diagnostic code to each condition, pull a percentage from the schedule, set your effective date, and either grant, deny or defer each issue. The decision is then reviewed and authorized — promulgation is simply the VA’s word for making it official — and the decision letter and code sheet are generated and mailed. Where an award is made, payment follows the effective date rules, and back pay is calculated to that date.

Read the code sheet, not just the percentage. It names the diagnostic code used, the exact measurements relied on and the effective date assigned — and that is where most mistakes live. This is a human being reading a file under a production quota, and the two things that go wrong most often are a rater using the pre-repetition range-of-motion numbers instead of the worst-case figures §4.59 and §4.40 require, and a claimed condition being decided on a thin record or quietly left out. Check whether painful motion was accounted for, whether your radiculopathy was rated separately under Note (1) or folded into the spine rating, and whether every condition you claimed was actually addressed. A decision you do not read is a decision you cannot challenge — and the deadline to challenge it starts the day the letter is dated, not the day you understand it.

C&P examination is the decision letter

The day it lands in your mailbox

The envelope holds two different documents: the narrative decision letter, and the code sheet. Together they are the single most important piece of paper in your claim, because every deadline, every appeal option and every dollar of back pay is set by what is printed on them — not by what you were told at the exam.

Most veterans read one thing on that letter: the percentage. Then they either celebrate it or get angry at it, and file it in a drawer. That is the mistake. The percentage is the conclusion; the reasons section is the reasoning, and the reasoning is what you attack. It tells you which diagnostic code the rater used, which range-of-motion figures they relied on and which they ignored, whether painful motion under §4.59 was accounted for, whether your neurological findings were rated separately under Note (1) or folded into the spine rating, which conditions were decided, which were deferred, and which were never addressed at all. It also assigns your effective date, which controls back pay. A rating that looks low is very often not a disagreement about how bad your neck is — it is a rater who used the pre-repetition numbers, or missed the radiculopathy, or rated one side and not both. You cannot see any of that from the percentage. Do not go by the percentage alone, and do not decode it by yourself if you are not sure what you are looking at — have someone who reads these for a living read it with you before the clock runs out. You have one year from the date on that letter to file a Higher-Level Review (VA Form 20-0996), a Supplemental Claim (VA Form 20-0995) or a Board appeal, and the deadline runs from the date printed on the letter, not the date you opened it. Bring it to this office and we will go through it line by line, at no cost, and tell you plainly whether it is right.

What normal looks like: 30 to 60 days for a simple claim, longer for a complex one

After your exam you should expect some kind of notification from the VA — a decision, a request for more information, or a notice that another exam has been scheduled. For a straightforward, single-issue claim that often lands within 30 to 60 days. But 30 to 60 days is a rough guide, not a rule, and it is not a ceiling. A claim with several conditions, a toxic-exposure or presumptive question, a returned exam, or missing records routinely takes 90 days or more, and that alone does not mean anything is wrong — the more moving parts your case has, the longer the VA takes to work it. Inside the window that is normal for a case like yours, silence is expected and there is nothing to fix, and a tracker that jumps backward is normal too.

What matters is not a fixed number of days — it is whether the claim is still moving and whether you can get a straight answer about where it is. Once you are well past what is normal for a case like yours and the VA either goes silent or cannot tell you what the claim is waiting on, stop waiting. That is usually where the real trouble hides — an exam that came back twice, a records request that was never answered, a claimed condition that got dropped, or a file sitting in the wrong queue. Call the VA at 800-827-1000, ask specifically what the claim is waiting on and who it is assigned to, and write down the answer. If you cannot get a straight answer, or the answer tells you the exam is the problem, that is the moment to bring it to this office rather than sitting on it for another three months. Problems raised early get fixed inside the claim. Problems discovered in a denial letter get fixed on appeal, and that costs you a year.

Other things that control the clock

Six things decide how long you wait, and none of them are visible from the tracker alone.

Check it at the source, not second-hand

The VA publishes an average days-to-complete figure for disability claims that moves month to month; check the current number on the VA’s own claim status page rather than relying on any second-hand figure. In practice, most veterans see a decision somewhere between roughly three and eight months from the date the claim was filed, with the exam usually falling in the middle of that window.

The exam is not the last step

Three stages still sit in front of you

The exam is not the last step. The clock does not start at the exam and it does not stop there either — the claim still has to clear evidence gathering, the rating decision and authorization.

A returned exam is the invisible delay

The reason a tracker slides backward

A returned or clarified exam is the most common invisible delay, and it is why a tracker can slide backward. Expect some contact from the VA within 30 to 60 days of the exam. Past 60 days with nothing at all, call and ask specifically what the claim is waiting on.

30 to 60 days is a guide, not a deadline

A complex case can take 90 days or more

Thirty to sixty days is a rough average for a simple, single-issue claim — not a hard rule and not a ceiling. A claim with several conditions, a presumptive or toxic-exposure question, a returned exam, or missing records can easily take 90 days or more, and that alone does not mean anything is wrong. Watch whether the claim is still moving, not the calendar. Only when it stalls well past what is normal for a case like yours, and no one can tell you what it is waiting on, should you stop waiting — call 800-827-1000 and ask what the claim is waiting on and who it is assigned to.

Watch your status yourself — in one of three places

Weekly, not daily

Check your own status in one of three places: your VA.gov claim status page, the VA Health and Benefits mobile app, or by calling 800-827-1000. Check it weekly, not daily. And understand exactly what a status check can tell you: if a decision is posted in your account, it is live; if it is not posted, it is not ready. That is the whole rule. This is not something your representative or your attorney can speed up — we see the same thing you see, at the same time, and calling us to ask does not move it. Calling the VA to ask for an update does not move it either. Watch it yourself, weekly, and the moment a decision posts, bring it to us.

06

Your decision letter arrives — read it, then start the appeal clock

What to do the day it lands in your mailbox

The decision letter is the finish line of the claim and the starting line of the appeal — and the moment it arrives, a one-year clock starts running. Read it the same day. Find the combined rating, the percentage assigned to each condition, and the effective date, because the effective date controls how far back your back pay reaches. Then request a copy of your C&P exam report so you can see whether the rater used your real range-of-motion numbers or ignored the radiculopathy. If any part of the decision is wrong — a low rating, a denied condition, or a bad effective date — you have three appeal lanes, and you must choose one within one year of the date printed on the letter: a **Higher-Level Review (VA Form 20-0996)**, where a senior reviewer re-decides on the same evidence; a **Supplemental Claim (VA Form 20-0995)**, when you have new and relevant evidence such as a private DBQ or your own range-of-motion exam; or a **Board Appeal (VA Form 10182)** to a Veterans Law Judge. Miss that one-year deadline and the decision becomes final. You can still file again later, but you lose the original effective date — and that lost time is lost back pay you never get back. Bring the letter to this office before the year runs out and we will read it with you, line by line, at no cost.

07Remedy

How to report a bad exam

Where this exam goes wrong

The single most common failure in this exam is an examiner who measures flexion and extension, writes "no instability noted," and never performs a Lachman. A one-word negative with no test named is not a finding. If the report shows no stability testing performed, or shows testing on the wrong knee, that exam is inadequate under **38 CFR §4.2** and it can be challenged rather than accepted.

Date, start time, end time, the examiner’s name and credentials, the vendor, every test that was performed, and every test that was not. A contemporaneous note written the same day is evidence. A memory reconstructed four months later is not.

Name the defect specifically, with the citation

Never write "the exam was unfair." Write "no goniometer was used, contrary to 38 CFR §4.46" or "flare-ups were reported and not addressed, contrary to Sharp v. Shulkin" or "repetitive use testing was not performed, contrary to 38 CFR §4.40 and DeLuca." A specific, citable defect is what forces action.

VA Form 21-4138, Statement in Support of Claim, filed through VA.gov or mailed to the Evidence Intake Center. State the defect, cite the authority, and request a new or supplemental examination. Do this BEFORE the decision if the claim is still open — it is far easier than undoing a decision afterward.

If the problem is behavior rather than methodology — you were rushed out, dismissed, never touched, or treated with hostility — file a complaint with the VA facility’s Patient Advocate, or with the vendor directly for a contract exam, and copy the Regional Office. Conduct complaints and adequacy challenges are two different tracks and you can run both.

If a decision has already issued, pick the right lane

A Higher-Level Review (VA Form 20-0996) argues the VA erred on the evidence it had — the right vehicle when the exam was inadequate on its face. A Supplemental Claim (VA Form 20-0995) is the vehicle when you are adding new and relevant evidence, such as your own private range-of-motion examination or a completed DBQ from your treating provider.

Put your own measurements on the table

A private examination with full goniometric measurements, or a DBQ completed by your own provider, creates a conflict in the evidence that the VA has to resolve — and under 38 CFR §3.102 reasonable doubt is resolved in your favor.

The Questions Veterans Actually Ask

Knee Instability Claims — Frequently Asked Questions

Straight answers to the questions that decide knee instability claims — the ratings, the separate evaluations, and the exam mistakes that cost veterans money.

Knee Instability is evaluated under DC 5257. The scale runs across 7 rating levels, and the highest is 10%, which the VA assigns for: Ligament instability. Sprain, incomplete ligament tear, or complete ligament tear (repaired, unrepaired, or failed repair) causing persistent instability, without a prescription from a medical provider for an assistive device (cane, crutches, walker) or bracing for ambulation. Where your evaluation actually lands depends on how your exam and records document those criteria — not on how bad the condition feels on an average day.
