Degenerative Arthritis Secondary to Knee, Other Impairment of
A condition caused or aggravated by an already service-connected disability can be granted its own service connection as a secondary condition under 38 CFR § 3.310. Here's how that works for Degenerative Arthritis when it develops after Knee, Other Impairment of.
Why Degenerative Arthritis Is Linked to Knee, Other Impairment of
Misalignment causes wear
Primary condition · VASRD 5257
Knee, Other Impairment of
This diagnostic code covers knee instability — the knee buckling, giving out, or shifting out of place — separately from pain or arthritis. Since the 2021 rewrite it rates two named things: recurrent subluxation or instability after a ligament sprain or tear, and instability of the kneecap (the patellofemoral complex) after surgical repair. The tier you land on depends less on how bad the instability feels than on what a medical provider has prescribed for it — a brace, a walking aid, both, or neither.

Degenerative Arthritis
Degenerative arthritis (osteoarthritis) is the gradual breakdown of the cartilage that cushions a joint, producing pain, stiffness, swelling and reduced motion. DC 5003 is not primarily a ladder of its own: the schedule rates degenerative arthritis established by X-ray "on the basis of limitation of motion under the appropriate diagnostic codes for the specific joint or joints involved", so most evaluations come from the affected joint's own code and DC 5003 supplies a floor.
Degenerative Arthritis VA Rating Tiers
The VA rates Degenerative Arthritis the same way whether it's claimed directly or as secondary to Knee, Other Impairment of — severity of Degenerative Arthritis itself determines the percentage.
Example combined rating
20% Knee, Other Impairment of + 10% Degenerative Arthritis = 28%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 20% and 10% combine to 28%, not 30%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
