Quick Answer: The VA rates knee conditions primarily by range of motion — specifically flexion (bending) and extension (straightening). Most veterans receive 10% for their knees when they should receive more, because they don’t know how to communicate painful motion or instability during their C&P exam.
How the VA Rates Knee Conditions
Knee conditions are rated under several Diagnostic Codes depending on the specific condition. For limitation of motion (the most common rating basis), DC 5260 (limitation of flexion) and DC 5261 (limitation of extension) apply:
| Condition | Rating |
|---|---|
| Flexion limited to 60° | 10% |
| Flexion limited to 45° | 20% |
| Flexion limited to 30° | 30% |
| Flexion limited to 15° | 40% |
| Extension limited to 10° | 10% |
| Extension limited to 15° | 20% |
| Extension limited to 20° | 30% |
| Extension limited to 30° | 40% |
| Extension limited to 45° (cannot walk) | 50% |
Instability and Painful Motion
Beyond range of motion, the VA can rate knees under DC 5257 (recurrent subluxation or lateral instability) at 10%, 20%, or 30%. If your knee gives out, buckles, or is unstable, make sure to describe this at your C&P exam — it may warrant a separate or higher rating in addition to your limitation of motion rating.
The painful motion rule (38 CFR § 4.59) requires the VA to assign at least the minimum compensable rating when movement of a joint is painful. If your knee is painful at any point during range of motion, report this clearly to the examiner. Do not push through pain to demonstrate maximum range — stop at the point of pain and say “it’s painful here.”
Bilateral Knee Claims
If both knees are service connected, the bilateral factor applies (38 CFR § 4.26). Both knees are combined first using the Whole Person method, then 10% of that combined value is added before entering the overall combined ratings table. File for both knees separately with individual ratings for each — don’t let the VA lump them into one condition.
Secondary Conditions to Claim
- Hip pain: Altered gait from service-connected knee conditions causes secondary hip degeneration — a well-documented medical relationship
- Back pain: Knee-related gait changes can cause or worsen lower back conditions
- Ankle conditions: Compensatory patterns from knee injuries frequently cause ankle problems
Frequently Asked Questions
Does a knee replacement affect my VA rating?
Yes — significantly. A total knee replacement is rated at 100% for one year following surgery (the recovery period), then re-evaluated based on residual limitation of motion and pain. Partial replacements and other surgical procedures have specific rating criteria as well. If you’ve had knee surgery, review your rating under the post-operative criteria.
My knee was injured during PT, not combat. Does it still qualify?
Yes. Service connection covers any injury or condition incurred or aggravated while on active duty — including injuries during physical training, sports, or routine military activities. You do not need a combat-related injury to receive VA disability for a knee condition.
