Knee Replacement (Total Knee Arthroplasty)

VA disability rating criteria for Knee Replacement (Total Knee Arthroplasty) under Diagnostic Code 5055. The VA assigns ratings of 30%, 60%, 100% based on the severity and functional impact of your condition.

Rating Criteria

30%Disability Rating

Minimum rating following knee replacement — intermediate degrees of residual weakness, pain, or limitation of motion rated by analogy to diagnostic codes 5256, 5261, or 5262.

Note: The 30% rating is the floor for any knee replacement after the 1-year 100% period. Intermediate residuals may warrant rating by analogy to DC 5256 (ankylosis), DC 5261 (extension limitation), or DC 5262 (flexion limitation).

60%Disability Rating

Chronic residuals consisting of severe painful motion or weakness in the affected extremity.

100%Disability Rating

Prosthetic replacement of knee joint — for 1 year following implantation of prosthesis.

Note: A 100% rating is assigned automatically for 1 year post-implantation to allow recovery. After 1 year, the VA must schedule a mandatory examination and re-rate based on residuals.
