VA Knee Pain Claim Guide
How the VA rates knee conditions — limitation of motion, instability, and arthritis can all apply at once, and stacking them correctly is where most of the missed rating value is.
Knee claims can be rated under multiple diagnostic codes simultaneously: limitation of motion (DC 5260/5261), instability (DC 5257), and arthritis (DC 5003). Each applicable rating combines using VA math rather than one code overriding the others.
Knee claims often get rated under only a single diagnostic code when the actual condition supports two or three simultaneously. Instability and limitation of motion are legally distinct impairments and can stack — missing that distinction is one of the most common ways veterans end up under-rated for a knee condition.
Proving Service Connection
You need a current diagnosis, evidence of an in-service event or onset, and a medical nexus tying the two. Many veterans miss the third piece.
How It's Rated
Common Combinations
- DC 5260/5261 — limitation of flexion or extension (10–30%)
- DC 5257 — recurrent instability or subluxation (10/20/30%)
- DC 5003 — degenerative arthritis confirmed by imaging (10/20%)
Evidence That Helps
- Imaging confirming arthritis or structural damage
- Range of motion measurements from a C&P exam or treating provider
- Stability testing results (Lachman test, drawer test)
- Surgical records if any procedures have been performed

Why Stacking Codes Matters
A knee with both instability and limited range of motion — a common combination after ligament injury — can be rated under both DC 5257 and DC 5260/5261 at the same time, since they measure genuinely different impairments. Many veterans are rated under just one code because the C&P exam or the rater didn't fully document both aspects, which is worth flagging in a Higher-Level Review if it applies to your decision.
Don't Skip Stability Testing
Range of motion measurements alone won't capture instability, and instability alone won't capture limited motion — make sure your C&P exam or private evaluation explicitly tests and documents both. If your prior exam only covered one, that's specific, actionable grounds for requesting a more complete evaluation.
Meniscus and Cartilage Damage Use Separate Codes Too
Beyond range of motion and instability, meniscus tears and cartilage damage are evaluated under their own diagnostic codes entirely (DC 5258, 5259), which can add yet another combinable rating if you have a documented meniscus injury alongside the other knee findings. A comprehensive knee claim benefits from making sure every diagnostic code relevant to your specific condition gets considered, not just the most obvious one.

Conclusion
If you have a current diagnosis and an in-service link, a knee pain claim is worth filing. Educational only. Not legal advice.
