How the VA rates Limitation of Extension of the Leg (Knee)
Knee extension limits your ability to fully straighten your leg. This diagnostic code covers a specific, measurable limitation: how far you're able to straighten the knee. Unlike general knee pain, this rating is driven almost entirely by a precise angle measurement, so how and when that measurement is taken can significantly affect the outcome.
The rating is set directly by a goniometer reading - a tool that measures joint angle - taken during a VA Compensation & Pension exam or orthopedic assessment. Because range of motion can vary depending on pain, warm-up, and time of day, the VA looks for a measurement that reflects your knee's typical, day-to-day limitation, not a best-case result.

How does the VA choose a rating level?
Which level applies is set by the criteria the evidence meets, not by the diagnosis. Where there is a question as to which of two evaluations applies, 38 CFR § 4.7 assigns the higher one if the disability picture more nearly approximates the criteria required for that rating.

THE EVERYDAY PICTURE
What the Limitation of Extension of the Leg (Knee) examination has to record
The criteria above are read off an examination, and three sections of Part 4 govern what that examination has to contain. None of them is a diagnostic code, so none of them appears in the 5261 table, and all three apply to it. 38 CFR § 4.40: “Weakness is as important as limitation of motion, and a part which becomes painful on use must be regarded as seriously disabled.”
38 CFR § 4.45 lists what an examination of a joint is directed to consider:
- Less movement than normal (due to ankylosis, limitation or blocking, adhesions, tendon-tie-up, contracted scars, etc.).
- More movement than normal (from flail joint, resections, nonunion of fracture, relaxation of ligaments, etc.).
- Weakened movement (due to muscle injury, disease or injury of peripheral nerves, divided or lengthened tendons, etc.).
- Excess fatigability.
- Incoordination, impaired ability to execute skilled movements smoothly.
- Pain on movement, swelling, deformity or atrophy of disuse.
38 CFR § 4.59: “It is the intention to recognize actually painful, unstable, or malaligned joints, due to healed injury, as entitled to at least the minimum compensable rating for the joint.” So a joint that is painful on use is not a finding of nothing, even where the measured motion is close to normal.
The same section says how the joint is to be tested: “The joints involved should be tested for pain on both active and passive motion, in weight-bearing and nonweight-bearing and, if possible, with the range of the opposite undamaged joint.” An examination that records one measurement, taken once, sitting down, has not done what the section asks, and that is worth reading the exam report for.

Preparing your Limitation of Extension of the Leg (Knee) claim
Start with the practical tips, then explore the common oversights. You don’t need to work through everything at once.
Practical tips for your claim3 tips
- 01
Make sure the range-of-motion exam happens without warming up beforehand - testing a knee 'cold' (as it typically is during daily activity) gives a more accurate, and often more favorable, extension measurement than testing after stretching.
- 02
Document specific functional impacts like difficulty with stairs, squatting, or prolonged standing - this context helps an examiner connect the numeric measurement to real-world limitation.
- 03
Bring physical therapy records and imaging (X-ray or MRI) alongside the goniometer results, since imaging showing the underlying cause of the limitation supports the objective measurement.
C&P exam pitfalls to keep in mind3 tips
- 01
Having range of motion measured after warming up or stretching, which can produce a better result than the knee's typical daily function and lead to an understated rating.
- 02
Not reporting pain during the extension test itself - pain on motion can support additional consideration beyond the angle measurement alone.
- 03
A single measurement with no repeat testing for consistency, which examiners may weigh less heavily than a documented pattern.
Common filing mistakes3 tips
- 01
Not including a goniometric exam at all - without this specific measurement, the VA has no objective basis to rate under this diagnostic code.
- 02
Describing only pain without quantifying the actual functional limitation in degrees, since the rating schedule for this code is angle-based, not symptom-based.
- 03
Leaving out medical history or imaging that explains why the extension loss exists in the first place.
When symptoms may first appear2 tips
- 01
Limited knee extension frequently follows surgery, an injury, or arthritis that has progressed enough to physically block the joint from fully straightening.
- 02
It often develops gradually, with the extension deficit slowly worsening as the underlying joint damage progresses, which is why periodic re-measurement can matter for tracking a worsening claim.

This diagnostic code covers a specific, measurable limitation: how far you're able to straighten the knee. Unlike general knee pain, this rating is driven almost entirely by a precise angle measurement, so how and when that measurement is taken can significantly affect the outcome.
What VA disability rating can I get for Limitation of Extension of the Leg (Knee)?
Possible VA ratings for Limitation of Extension of the Leg (Knee) are 50%, 40%, 30%, 20%, 10%, 0%. Examples: 50%: Extension limited to 45 degrees; 40%: Extension limited to 30 degrees; 30%: Extension limited to 20 degrees.
What's the typical VA rating awarded for Limitation of Extension of the Leg (Knee)?
Vetrify estimates the typical rating awarded for Limitation of Extension of the Leg (Knee) at around 10%, based on VA claims data and the rating schedule. An estimated 152,700 veterans are service-connected for Limitation of Extension of the Leg (Knee). Estimated approval outlook: High – well-documented ROM loss leads to reliable ratings.
What evidence helps prove Limitation of Extension of the Leg (Knee) for VA disability?
Strong evidence for a Limitation of Extension of the Leg (Knee) claim includes: A documented goniometric measurement of extension loss - this is the specific evidence the diagnostic code is built around; Physical therapy evaluations that track range of motion over time, showing consistency rather than a single measurement; Knee X-ray or MRI results identifying the underlying cause (arthritis, prior surgery, ligament damage) of the extension loss.
Which DBQ is used for Limitation of Extension of the Leg (Knee)?
VA's Knee and Lower Leg Disability Benefits Questionnaire (DBQ) is on its public list of DBQs. VA's page says: "You can use these forms to submit medical evidence from your health care providers."
