VA Disability Rating for Knee Conditions: 2026 Guide

Knee conditions are among the most common service-connected disabilities in the VA system. Years of rucking, jumping, running, and operating in difficult terrain take a toll. Getting the right knee rating requires understanding which diagnostic code the VA uses — and making sure they evaluate all your limitations.

Key Diagnostic Codes for Knees

• DC 5260 — Limitation of flexion (bending)
• DC 5261 — Limitation of extension (straightening)
• DC 5257 — Recurrent subluxation or lateral instability (giving way)
• DC 5055 — Knee replacement

The VA must rate your knee under whichever code produces the highest rating. If your knee is both limited in motion AND unstable, the VA should evaluate both and apply the higher one.

Limited Flexion (DC 5260)

Instability (DC 5257)

Bilateral Knees — The 10% Bonus

If both knees are service-connected, the VA applies the bilateral factor — a 10% bonus on those ratings before combining with your other conditions. Check the "bilateral" checkbox in the calculator to see how this affects your total pay.

Painful Motion Rule

Under 38 CFR 4.59, any joint that causes pain on use must be rated at least at the lowest compensable level (10%). If your knee hurts when you move it, say so clearly at the C&P exam. Document the specific movements that cause pain.

Secondary Conditions from Knees

Knee problems cause secondary conditions: hip conditions from altered gait, lower back pain from compensating posture, and depression from chronic pain — all separately ratable.

Frequently Asked Questions

How does the VA rate knee conditions?

The VA rates knees primarily by range of motion — limited flexion (DC 5260) and limited extension (DC 5261) — as well as instability (DC 5257). The VA must apply whichever code gives the highest rating.

What is the rating for limited knee flexion?

10% for flexion limited to 45 degrees, 20% for 30 degrees, 30% for 15 degrees. Most veterans with knee problems receive 10% for limited flexion.

Does the VA give extra pay for both knees?

Yes — the bilateral factor adds a 10% bonus to paired body part ratings. Both knees service-connected means a 10% bonus on those ratings before combining with other conditions.

What evidence do I need for a VA knee claim?

Current medical evidence (X-rays, MRI, physical exam), documentation of in-service injury or overuse, and a nexus letter if not already in your service treatment records.
