Knee Condition Secondary to Ankle, Foot, or Hip (Altered Gait)
Why altered-gait claims succeed
An antalgic gait — limping, shortened stride, or weight-shift away from a painful joint — places asymmetric load on the unaffected lower extremity. Over time, this contributes to meniscal wear, ligamentous strain, and accelerated osteoarthritis. The medical literature on gait kinematics supports this link, and VA recognizes it as a valid theory when the file contains evidence of the gait abnormality.
Building the file
- Document the gait abnormality — physical therapy notes, podiatry records, prosthetist notes, or VA primary-care notes describing the limp, shortened stride, or weight shift.
- Document the new knee diagnosis — imaging showing osteoarthritis, meniscal tear, or chondromalacia; clinical findings of limitation of motion or instability.
- Obtain a medical opinion that names the altered-gait mechanism explicitly and concludes that the knee condition was caused or aggravated by the service-connected ankle / foot / hip condition.
How the knee is rated
- 5260 — limitation of flexion (45° = 10%, 30° = 20%, 15° = 30%).
- 5261 — limitation of extension (10° = 10%, 15° = 20%, 20° = 30%).
- 5257 — instability/subluxation (slight 10%, moderate 20%, severe 30%).
- 5258 / 5259 — meniscus pathology.
- 5003 — degenerative arthritis with (separate combinable rating in some cases).
Separate ratings when warranted
Limitation of flexion ( 5260) and limitation of extension (DC 5261) of the same knee can be rated separately — they are different functional losses. Instability under DC 5257 is rated separately from arthritic limitation of motion (VAOPGCPREC 23-97). Bilateral knee involvement triggers the under § 4.26.
Where these claims break down
- ×Filing without any documentation of the gait abnormality in the medical record.
- ×Accepting a single combined 'knee pain' rating when separate flexion, extension, and instability ratings apply.
- ×Skipping the aggravation theory — even pre-existing knee arthritis can be compensable if the gait accelerated it.
- ×Forgetting the bilateral factor when both knees are involved.
