Knee Limitation of Extension

DC 5261Musculoskeletal38 CFR 4.71a, DC 5261

Limited ability to straighten the knee. The VA rates this based on how far you can extend (straighten) your knee. Normal extension is 0 degrees (fully straight).

How the VA rates this condition

The VA rates this condition primarily based on range-of-motion measurements. During your C&P exam, the examiner will use a goniometer to measure how far you can move the affected joint. Pain, flare-ups, and repetitive-use limitations also factor into the final rating.

Common Pitfalls

⚠Same as knee flexion — extension and flexion can be rated separately under DC 5260 and 5261.
⚠Not documenting that the knee cannot fully straighten — even a few degrees of limitation counts.
⚠Not filing for instability separately under DC 5257.
