Knee condition VA claims: what the Board relied on in grants and denials

What does VA need to service connect a knee condition?

Generally a current knee disability, an injury or disease in service, and a medical link between the two; 38 CFR 3.303 sets out the principles. Knee arthritis can also be presumed if it reached a compensable level within a year of discharge (38 CFR 3.307(a)(3) and 38 CFR 3.309(a)).

For combat veterans, 38 CFR 3.304(d) also lets a credible account of an injury in combat prove it happened. Knee claims are rated under DC 5256 to DC 5263, and knee arthritis under DC 5003.

Most knee claims are sent back first

Of 29,590 veterans whose knee claim the Board decided from 2020 to 2025, it granted 20.4%, denied 23.6% and remanded 56.0%. The comparison below sets the 6,035 grants against the 6,986 denials.

What separated knee grants from denials?

A positive nexus opinion was in 51.4% of grants and 8.5% of denials, and the Board found the veteran credible in 54.1% of grants and 11.5% of denials. With both, it granted 77.4%; with neither, 5.4%.

One count per veteran; a remand counts as not granted.

With both, the Board granted 1,436 of 1,855 claims. A credibility finding without a positive opinion was granted 46.7%, and a positive opinion without a credibility finding 51.1%. Most claims had neither: 20,556 veterans, of whom 1,102 were granted.

Why are knee claims denied?

For 6,869 denials, the decision summary noted what was missing: a medical link in 68.0% of them and the in-service injury in 52.2%. The diagnosis was rarely the problem (10.1%).

A knee injury in service may not be recorded at all, or recorded only once. Service records were discussed in nearly every decision (89.2% of grants, 96.1% of denials), so their presence says little; what they show is what counts.

Does a negative VA opinion end a knee claim?

No. An unfavorable VA exam was in 82.1% of grants, because the Board weighs it against the other evidence. A private medical opinion was in 53.5% of grants and 29.1% of denials.

The Board can find a VA opinion inadequate, for example when it ignores the veteran's account of symptoms in service. In the first grant below, credible statements about symptoms in service outweighed a negative VA opinion.

Read the decisions

Recent decisions, with the Board's reasoning as summarized by AI:

• A26040542, April 2026: both knees granted, including a meniscal tear and arthritis; credible lay evidence of symptoms in service outweighed a negative VA opinion.
• A26040500, April 2026: a bilateral knee condition granted; statements about knee strain as a cannon crewmember were credible, and a private medical opinion linked the injuries to the current disability.
• A26040694, April 2026: a left knee condition denied; no knee complaints in service, and a VA examination found no knee diagnosis.

What the data cannot tell you

These are what the decisions contained, not what caused the result. Some items, such as a credibility finding or the benefit of the doubt, are part of how the Board explains a grant. The evidence items were extracted by AI and apply to the whole decision. Historical outcomes, not predictions.

For representatives

• Get a medical opinion that addresses the in-service injury and explains the link; denials turned on that most often.
• Build credibility where the injury was not recorded: consistent statements, buddy statements, and the duties that strained the knee.
• Challenge a VA opinion that ignores the veteran's account of symptoms in service.
