Musculoskeletal
Knee & Lower Leg Conditions
Instability, limitation of motion, and the rule against pyramiding
Knee conditions can carry more than one rating at once — instability and limitation of motion are rated separately. Most veterans are only rated for one.
Each Condition, Broken Out
Every Condition In This Category Has Its Own Page
These are separate diagnostic codes with separate criteria, separate exams and separate money. Each one below opens a full page: how it is rated, the schedule spelled out, the service-connection arguments, and exactly what happens at that specific C&P exam.
DC 5257
Knee Instability — Recurrent Subluxation and Patellar Instability
The knee gives way underneath you. The ligaments no longer hold the joint where it belongs.
Read the full Knee Instability page
DC 5260 · 5261
Limitation of Range of Motion of the Knee — Flexion and Extension
The knee will not bend far enough, or will not straighten all the way. Both are measured in degrees on a goniometer — and each direction is its own rating on the same knee.
Read the full Range of Motion page
DC 5258 · 5259
Semilunar Cartilage — Dislocated Meniscus and Meniscectomy Residuals
The shock absorber in the knee is torn, displaced, or has been cut out. The joint locks, swells, and hurts.
Read the full Meniscus page
DC 5003 · 5010
Degenerative and Post-Traumatic Arthritis of the Knee
The cartilage is worn through and bone is working against bone. It is stiff in the morning and it never fully goes away.
Read the full Knee Arthritis page
DC 5256
Ankylosis of the Knee
The knee is fused. It does not move at all — and the angle it is frozen at decides the rating.

DC 5262
Impairment of the Tibia and Fibula, and Medial Tibial Stress Syndrome
The shin bones themselves — a fracture that never knitted straight, or shin splints that never stopped.

What Knee & Lower Leg Conditions Really Is
Knee disability is loss of motion, instability, and cartilage or meniscus damage — plus the surgical residuals and the arthritis that follows years later.
What it actually means
Knee disability is loss of motion, instability, and cartilage or meniscus damage — plus the surgical residuals and the arthritis that follows years later.
What the VA measures
Multiple diagnostic codes in 38 CFR §4.71a at once: limitation of flexion (5260) and extension (5261) by degrees, recurrent subluxation or lateral instability (5257), and meniscus pathology (5258/5259).
Why claims get missed
Only one code gets claimed. Limitation of motion and instability are separately ratable for the same knee, and both knees are separate ratings with a bilateral factor added on top.
What in Your Service Causes Knee & Lower Leg Conditions
Service connection is not a feeling, it is a chain of evidence. These are the pathways the VA already recognises. Find yours, then make sure your file says it out loud.
Ruck, run, and load-bearing wear
Cumulative impact from running in boots on pavement, ruck marches, and body-armor weight is the standard mechanism for patellofemoral and meniscal injury.
Airborne and hard-landing trauma
Jump injuries, fast-rope, and vehicle egress produce ligament and meniscus damage often treated in sick call as a sprain.
Obstacle courses and PT injury
Documented PT-related knee injuries in your service treatment records are direct evidence, even when the note says the injury resolved.
Altered gait from another injury
A service-connected ankle, hip, or opposite-knee condition shifts load onto the knee and is a recognized secondary pathway under §3.310.
Two Ratings for One Knee
The VA General Counsel has confirmed that a knee with both instability (Code 5257) and arthritis with limitation of motion (Codes 5003/5260/5261) can receive separate ratings for each, because they compensate different functional losses and do not constitute pyramiding. Most veterans are rated for only one and never told they qualified for both.
Getting the Measurements Right
Flexion and extension are measured in degrees, and painful motion begins the compensable range earlier than examiners often record. Instability is graded slight, moderate, or severe based on ligament laxity. Meniscus conditions, dislocated cartilage, and post-surgical residuals each have their own diagnostic codes.
What to Document
Buckling, giving way, or use of a brace (instability)
Measured flexion and extension with pain onset
Locking and effusion for meniscus claims
Secondary hip or opposite-knee strain from altered gait
Establishing Service Connection
To establish service connection for a musculoskeletal condition, veterans must meet three criteria. First, there must be a current diagnosis. Second, there must be evidence of an in-service injury, repetitive strain, or the physical demands of your duties that could have caused or aggravated it. Third, a nexus — a medical link — must connect the in-service event to the current condition.
Current diagnosis of the joint or spine condition
In-service injury, repetitive strain, or documented physical demands
Medical nexus linking the condition to service ("at least as likely as not")
Imaging (X-ray or MRI) showing arthritis, disc disease, or joint damage
Lay statements describing onset and continuity of pain since service

Our advocates are trained to identify and link service-related conditions, increasing the likelihood of a successful claim. We also provide personalized representation, helping veterans navigate appeals and secure the benefits they deserve. As a VA-Accredited Claims Agent, our fees are regulated under 38 CFR §14.636 — and there are no fees unless we win your appeal.
The Rating Schedule, Spelled Out
Knee conditions are rated under 38 CFR §4.71a, Diagnostic Codes 5256–5263. Instability (5257) and limitation of motion (5260/5261) compensate different functional losses, so a single knee can legitimately carry both ratings without pyramiding. Every code in the range is reproduced below.
Note on the 2021 amendment: the criteria for Diagnostic Code 5257 (instability) and 5262 (tibia and fibula) were rewritten effective February 7, 2021. The current criteria are shown below. 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.
Favorable angle in full extension, or in slight flexion between 0 and 10 degrees.
In flexion between 10 and 20 degrees.
In flexion between 20 and 45 degrees.
Extremely unfavorable, in flexion at an angle of 45 degrees or more.
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.
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.
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.
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.
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.
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.
Dislocated semilunar cartilage with frequent episodes of locking, pain, and effusion into the joint.
Semilunar cartilage removed, symptomatic.
Flexion limited to 60 degrees.
Flexion limited to 45 degrees.
Flexion limited to 30 degrees.
Flexion limited to 15 degrees.
Extension limited to 5 degrees.
Extension limited to 10 degrees.
Extension limited to 15 degrees.
Extension limited to 20 degrees.
Extension limited to 30 degrees.
Extension limited to 45 degrees.
Nonunion of the tibia and fibula, with loose motion, requiring a brace.
Malunion of the tibia and fibula is evaluated under Diagnostic Codes 5256, 5257, 5260 or 5261 for the knee, or 5270 or 5271 for the ankle, whichever results in the highest evaluation.
Treatment for less than 12 consecutive months, one or both lower extremities.
Requiring treatment for no less than 12 consecutive months, and unresponsive to either shoe orthotics or other conservative treatment, one or both lower extremities.
Requiring treatment for no less than 12 consecutive months, and unresponsive to surgery and either shoe orthotics or other conservative treatment, one lower extremity.
Requiring treatment for no less than 12 consecutive months, and unresponsive to surgery and either shoe orthotics or other conservative treatment, both lower extremities.
Genu recurvatum (acquired, traumatic) with weakness and insecurity in weight-bearing objectively demonstrated.
Key Points to Remember
Rated under 38 CFR §4.71a on range of motion (DC 5260/5261) and instability (DC 5257)
Separate ratings can apply for limitation of motion and instability of the same knee
Painful motion and flare-ups must be considered (§4.40 and §4.45)
Dislocated cartilage (DC 5258) and other findings can support additional evaluation
What to Expect at Your Knee C&P Examination
The knee is measured in two directions and tested for two separate things — motion and stability — and those are two separate ratings. Under Diagnostic Code 5260 flexion limited to 60 degrees is noncompensable, 45 degrees pays 10%, 30 degrees pays 20% and 15 degrees pays 30%. Under Diagnostic Code 5261 extension limited to 5 degrees is noncompensable, 10 degrees pays 10% and it climbs to 50% at 45 degrees. Normal knee motion for VA purposes is 0 degrees extension to 140 degrees flexion.
Goniometer flexion and extension on BOTH knees, active and passive, weight-bearing and non-weight-bearing.
Repetitive-use testing — three repetitions — then re-measurement, plus a flare-up estimate in degrees.
The degree at which pain begins in the arc, recorded separately from the endpoint (38 CFR §4.59).
Joint stability testing: anterior and posterior (Lachman, drawer) and medial-lateral. Since the February 7, 2021 revision, instability is rated on whether it is recurrent, on the need for an assistive device, and on whether surgical repair was performed — not on the old slight/moderate/severe wording.
Meniscal testing — McMurray and joint-line tenderness — with documentation of locking, effusion and pain, which rate on their own under DC 5258 and 5259.
Measurement of thigh and calf circumference for quadriceps atrophy, and a note on crepitus.
Imaging review for degenerative arthritis, because arthritis plus instability is legitimately two ratings on one knee.
What Happens Once the C&P Exam Is Complete
The examiner compiles a detailed report — your medical history, physical findings, and diagnostic results — and assesses the severity, symptoms, and impact of your condition. That report is sent to the VA Regional Office handling your claim and becomes part of your official file, reviewed alongside your other evidence.
The VA may send the report back for corrections, clarification, or a second opinion if it finds it incomplete or unclear. This can delay your claim, because the VA requires thorough and accurate information to decide. Your claim only moves to the decision phase once the VA is satisfied with the evidence — which is exactly why the quality of the file we build for you matters so much. Once decided, your effective date controls how far back your back pay reaches, and any denial can be challenged through a Supplemental Claim, Higher-Level Review, or Board appeal.
The Advocate’s Take
One knee can legitimately carry two ratings. If yours has instability and arthritis, being rated for only one is money left on the table.
Every Level the VA Can Assign You
These percentages come straight out of the rating schedule that governs knee & lower leg conditions — Diagnostic Code 5256. Read them slowly. If your current rating does not match what your records actually show, that gap is exactly what an appeal exists to correct.
30%
Favorable angle in full extension, or in slight flexion between 0 and 10 degrees.
40%
In flexion between 10 and 20 degrees.
50%
In flexion between 20 and 45 degrees.
60%
Extremely unfavorable, in flexion at an angle of 45 degrees or more.
Secondary Claims — Both Directions
Under 38 CFR §3.310, a condition caused or made worse by an already service-connected condition is itself service connected. That runs in both directions, and it is the single largest pool of unclaimed compensation in the system.
What can cause knee & lower leg conditions
If one of these is already service connected, this condition can be claimed as secondary to it.
Service-connected ankle, hip, or opposite knee
Compensatory gait changes are an accepted cause of secondary knee disability.
Lumbar spine condition with radiculopathy
Weakness and instability from nerve involvement produces documented secondary knee injury.
What knee & lower leg conditions can cause
If this condition is already service connected, each of these is a separate claim you may be owed.
Lumbar spine strain and degeneration
A limp or altered gait from knee disability is a recognized cause of secondary spine disability.
Opposite knee and hip disability
Overloading the good leg for years produces separately ratable disability on the other side.
Depression from chronic pain and lost activity
Loss of mobility and continuous pain support a secondary mental health claim under §3.310.
A secondary claim still needs two things: a current diagnosis of the secondary condition, and a medical opinion saying it is at least as likely as not caused or aggravated by the service-connected condition. You do not have to prove it happened in service.
Building a Knee & Lower Leg Conditions Claim That Wins
Every claim stands on three legs. Knock one out and the claim falls over, no matter how bad your symptoms are. Before you file, look at your file and find all three.
A current diagnosis
A doctor has to say you have it, now, in writing. Not "reports symptoms of" — a diagnosis. Without this leg, nothing else in the file matters.
A link to your service
An event, an injury, an exposure, or an already service-connected condition. Service records, unit records, buddy statements, and your own account all count as evidence.
A nexus that ties the two together
A medical opinion stating it is at least as likely as not that your service caused or aggravated the condition. That phrase is a legal standard: 50 percent or better. It is the leg most denials break.
Document the problem before you file
• Keep a dated symptom log for at least 30 days. Frequency, severity, and what it stopped you from doing.
• Get statements from people who see it — a spouse, a coworker, a battle buddy. Lay evidence is legal evidence.
• Pull your private treatment records. The VA only has to help; it does not have to go find everything.
• Write down what you have stopped doing. Lost work, lost sleep, lost activities. That is what impairment looks like on paper.
Your Rights in This Process
It costs nothing to file
Filing a VA claim is free. Accredited representatives may only charge for work on an appeal after an initial decision, and those fees are capped by 38 CFR §14.636.
The VA has a Duty to Assist you
Under 38 CFR §3.159 the VA must help you get the evidence it needs, and it must tell you what is missing before it denies you for missing it.
You can ask for a different examiner
You may request a trauma-informed clinician, or a clinician of a specific gender, for a C&P examination. Ask before the exam is scheduled.
You can claim every condition you have
There is no limit and no penalty. Primary conditions, secondary conditions, and conditions made worse by service all get filed.
You can appeal and be re-evaluated
A denial is not the end. You may submit new evidence, request a higher-level review, appeal to the Board, and ask for re-evaluation when your condition worsens.
You must be considered for TDIU
If your service-connected conditions keep you from holding substantially gainful employment, you may be paid at the 100 percent rate without a 100 percent rating.
Questions Veterans Ask About Knee & Lower Leg Conditions Claims
Can I get more than one rating for the same knee?
Yes. Limitation of flexion under DC 5260, limitation of extension under DC 5261, and instability or recurrent subluxation under DC 5257 are separately ratable for the same knee because they compensate different functional losses. Meniscus pathology under DC 5258 or 5259 can add another.
What is the bilateral factor?
When both knees — or any paired extremities — are service-connected, 38 CFR §4.26 adds 10 percent of the combined value of those ratings before combining with everything else. It is applied automatically, but only if both sides are actually claimed and rated.
I had a knee replacement. What is that worth?
A total knee replacement is rated 100 percent for one year following implantation under DC 5055, then a minimum of 30 percent thereafter, with higher levels for chronic residuals including severe painful motion or weakness. Many veterans are never told about the one-year total rating.
My instability is not on the exam. What now?
Instability under DC 5257 depends on the examiner performing and documenting stability testing. If the DBQ shows no testing or you were not asked to describe giving way, buckling, or falls, the examination is inadequate for rating purposes and a new one should be requested.

What to Expect at Your C&P Exam
Your Compensation & Pension (C&P) exam is not treatment. It is a rating tool. The examiner will not fix anything — they complete a Disability Benefits Questionnaire (DBQ) and check the boxes that decide your rating. What happens in that room can move your rating an entire level, so walk in prepared.

TDIU — Paid at 100% Without a 100% Rating
Total Disability based on Individual Unemployability (38 CFR §4.16) pays you at the 100% rate when your service-connected conditions prevent substantially gainful employment — even if your combined rating is lower. You may qualify if:
- One condition is rated 60% or higher, or
- Two+ conditions combine to 70% with at least one rated 40%, and
- Those conditions keep you from holding steady, gainful work.
- Cannot meet the numbers? Extraschedular TDIU under §4.16(b) may still apply.
Special Monthly Compensation (SMC)
SMC (38 CFR §3.350) pays above the normal schedule for especially serious losses — loss or loss of use of a body part, being housebound, or needing the aid and attendance of another person. Common levels:
- SMC-K — Loss / loss of use — Add-on for loss or loss of use of a specific body part (hand, foot, eye, reproductive organ, or certain other losses). Paid on top of your regular compensation. Can stack (up to the statutory cap).
- SMC-S — Housebound — Statutory housebound: a single 100% disability plus additional disabilities of 60%+, or substantially confined to your home. Veteran-alone rate shown.
- SMC-L — Aid & Attendance — You need the regular aid and attendance of another person, or have anatomical loss/loss of use of both feet, one hand and one foot, blindness, or are permanently bedridden. Veteran-alone rate shown.
- SMC-M — Higher Aid & Attendance — A higher level of aid and attendance (e.g., loss of use of both hands, or loss of use of both legs at a higher level). Veteran-alone rate shown.
These are the benefits veterans most often leave on the table because no one told them they qualified. If any of this sounds like your situation, call an accredited agent at 702-992-4883 — we screen for SMC and TDIU on every case.
