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

What does VA need to service connect an ankle condition?

Generally a current ankle disability, an injury or disease in service, and a medical link between the two; 38 CFR 3.303 sets out the principles. Arthritis of the ankle 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)). Limited motion is rated under DC 5271, as moderate or marked.

Many ankle claims start with a sprain: 1,810 of them (19.7%) mention one. What the Board looks for next is a link from that injury, or from years of the same duties, to the condition today.

Most ankle claims are sent back first

Of 9,202 veterans whose ankle claim the Board decided from 2020 to 2025, it granted 17.4%, denied 25.6% and remanded 56.9%. The comparison below sets the 1,604 grants against the 2,359 denials.

What separated ankle grants from denials?

A positive nexus opinion was in 51.3% of grants and 9.0% of denials, and the Board found the veteran credible in 54.7% of grants and 11.7% of denials. With both, it granted 72.0%; with neither, 4.5%.

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

With both, the Board granted 389 of 540 claims. A credibility finding without a positive opinion was granted 42.7%, and a positive opinion without a credibility finding 46.0%. Most claims had neither: 6,576 veterans, of whom 293 were granted.

The old sprain

Can an ankle sprain in service lead to a grant years later?

Yes, if a medical opinion links the current condition to it. The claim or the Board's summary mentions a sprain for 1,810 veterans, and the Board granted 26.7% of those, above the share for ankle claims overall. For 2,327 denials, the Board's note named a missing medical link in 60.9% of them and the in-service injury in 44.0%.

A credible account helps here. The veteran's own statement was in almost every decision, grants and denials alike, so what counted was whether the Board believed it: it found the veteran credible in 54.7% of grants and doubted the veteran in 24.5% of denials. A buddy statement was rare in both (7.7% of grants).

Ankle claims made secondary to a foot or knee

Can an ankle condition be secondary to a foot or knee condition?

Yes, under 38 CFR 3.310, usually through a change in gait. The Board granted ankle claims made secondary to a foot condition for 83 of 395 veterans (21.0%) and to a knee condition for 56 of 415 (13.5%). Direct claims: 17.9%.

Route	Granted	Veterans	Share
Direct (from service)	1,334	7,453	17.9%
Secondary to a foot condition	83	395	21.0%
Secondary to a knee condition	56	415	13.5%
Secondary to a back condition	19	184	10.3%
Secondary to something else	130	897	14.5%

Most ankle claims are direct, and the secondary routes did not do better: only the foot route came out above direct claims. A secondary claim still needs an opinion that explains how the foot or knee changed the way the veteran walks and why that harmed the ankle.

Does a negative VA opinion end an ankle claim?

No. An unfavorable VA exam was in 82.5% of grants, because the Board weighs it against the other evidence. A private medical opinion was in 49.2% of grants and 27.6% of denials.

Read the decisions

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

• A25110426, December 2025: a right ankle strain granted as related to a right ankle sprain in service.
• A25108575, December 2025: strains of both ankles granted secondary to a service-connected knee condition, on an independent medical opinion, despite a negative VA exam and unavailable service records.
• A25111259, December 2025: right ankle pain denied; the Board found the private opinion inadequate because it rested only on the veteran's statements and conflicted with service records that showed a left ankle injury, not a right one.

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. The route table counts a veteran once per route, so a few appear on two. Increased-rating claims are left out. Historical outcomes, not predictions.

For representatives

• Find the in-service ankle injury in the records, and get a medical opinion that links it to the condition today; denials turned on that link most often.
• Back the account with consistent statements about symptoms since service, and a buddy statement if one is available.
• For a secondary claim, have the opinion describe the gait change and address aggravation as well as causation (38 CFR 3.310(b)).
