Counts from RateMyVSO's index of published BVA decisions, as of July 2026. "Granted 38%" counts only issues decided up-or-down: granted ÷ (granted + denied). A remand is not a loss; it means the Board needed more evidence before deciding. Secondary service connection rule: 38 CFR § 3.310.

Quick Checklist Before You File

  • Service connection already in place for Ankle Limitation, and a current medical diagnosis of degenerative arthritis.
  • Diagnostic testing, imaging, or clinical records documenting the degenerative arthritis, whatever your provider used to diagnose and track it.
  • A nexus opinion, whenever possible from a doctor familiar with degenerative arthritis, stating it is at least as likely as not caused or aggravated by the ankle limitation, and naming the mechanism rather than just the conclusion.
  • Lay statements: spouse, family, friends, or battle buddies describing what they've witnessed or noticed.
  • Your STRs and any VA opinions already in the file on either condition. If a VA opinion already went against you, your submitted opinion or statement should address its specific reasoning.

Why degenerative arthritis is claimed secondary to ankle limitation

Documented mechanism
A stiff or limited ankle changes the way a person walks, and that altered gait is a recognized cause of accelerated arthritis in the joints above and around it. When the ankle cannot move through its normal range, the foot, knee, and hip compensate, absorbing forces and moving through angles they were not designed for; over years the cartilage in those overworked joints wears down faster, producing degenerative arthritis. The ankle joint itself can also develop arthritis directly from the original injury that limited its motion. This biomechanical pathway, restricted motion in one joint overloading its neighbors, is well accepted in orthopedics. Whether it explains a particular veteran's arthritis depends on that veteran's own records, including the cause and degree of the ankle limitation, which joints are affected, imaging, and a clinician's opinion connecting the wear pattern to the altered gait.
This rationale is generated from the data for this specific pairing, not hand-written per page. The grant and denial figures above come only from the decision data, never from the rationale text.

Whether that medical link exists in any one case is a medical question decided on that case's own evidence (the nexus).

What a secondary claim on this pairing needs

Under 38 CFR 3.310 a secondary claim turns on three elements:

  • A current diagnosis: a medical diagnosis of degenerative arthritis (the secondary).
  • A service-connected primary: Ankle Limitation, already service-connected (the primary). A 0% primary still counts.
  • A medical nexus: a medical opinion linking the degenerative arthritis to the ankle limitation, showing the primary caused or aggravated it.

See the Secondary Claim guide for the caused-versus-aggravated split, and the Nexus Letter guide for what makes the medical opinion strong.

Do's and Don'ts

Do
  • Get service connection established for Ankle Limitation and a current diagnosis of degenerative arthritis documented before you file.
  • Get a nexus opinion that names the specific mechanism connecting the degenerative arthritis to the ankle limitation and cites supporting literature, not just a conclusion.
  • Include diagnostic testing, imaging, or clinical records for the degenerative arthritis.
  • Get a spouse, family, friend, or buddy statement describing what they've witnessed, lay evidence the Board credits directly.
  • If a VA opinion already exists in your file, have your own opinion rebut it point by point rather than simply asserting the opposite conclusion.
Don't
  • Don't accept "the study shows an association, not causation" as the final word, exact etiology and scientific consensus are not the legal standard (Alemany v. Brown, 9 Vet. App. 518 (1996); Wise v. Shinseki, 26 Vet. App. 517 (2014)).
  • Don't treat a VA examiner's "unable to determine without speculating" as evidence against you, an unexplained non-opinion is not evidence at all.
  • Don't let a service-to-diagnosis time gap sink your secondary claim, that gap matters for a direct claim, not this one.
  • Don't assume you need an expensive specialist, a treating provider's notes plus published literature have carried grants before.
  • Don't leave a negative opinion unchallenged if it never engaged your submitted literature or lay statements, the Board has downgraded exactly that kind of opinion to minimal weight.

The Claims Process, Step by Step

A secondary claim moves through the same pipeline as any other. Understanding who does what helps you know who to contact and what to expect.

  1. You file the claim, naming Ankle Limitation as the service-connected primary and degenerative arthritis as secondary. Directly with VA, through VA.gov, or with an accredited representative's help.
  2. VA assigns a Veteran Service Representative (VSR) to develop the claim: gather your service treatment records, VA and private medical records, and order a C&P exam if needed.
  3. The C&P exam is conducted, usually with the examiner asked to address the specific secondary theory (causation and aggravation both).
  4. The file goes to a Rating Veteran Service Representative (RVSR), the "rater," who weighs the medical evidence and decides service connection and, if granted, the rating percentage.
  5. VA issues the decision letter stating the outcome and the reasoning.
  6. If denied or under-rated, you choose an appeal lane, Supplemental Claim, Higher-Level Review, or a Board appeal, covered below.

Who's who: VSO vs. VSR vs. Rater vs. C&P Examiner

Your VSO

An accredited representative, agent, or attorney. Not a VA employee. Helps prepare and file, and can represent you on appeal. Has no authority to decide your claim.

VSR

VA staff who develops the claim: gathers records and schedules the exam. Does not decide the rating.

Rater (RVSR)

VA staff who reviews the complete file and makes the actual decision on service connection and percentage.

C&P Examiner

Conducts the exam and, where asked, gives a nexus opinion. Does not decide the claim, but the opinion's reasoning and legal framing carry real weight.

For the full walkthrough, see Inside Your Claim and Claim Stages.

DBQs and Your C&P Exam

A Disability Benefits Questionnaire (DBQ) is the standardized form the examiner completes for your condition. See the DBQ Guide for how these forms work and whether a private DBQ from your own doctor can be submitted instead of relying solely on a VA exam. For what to expect and how to prepare, see the C&P Exam Prep Guide, and be specific about how your degenerative arthritis symptoms relate to your ankle limitation timeline, treatment, and any aggravation, that is the detail a nexus opinion relies on.

Reading Your Decision Letter, and What to Do If Denied

Your decision letter has a narrative "reasons and bases" section and a codesheet with the rating and effective date. See the Reading Your Decision Letter Guide or use the Letter Interpreter tool to decode your own letter. If denied, you have three main lanes:

  • Supplemental Claim: refile with new and relevant evidence, such as a nexus opinion that addresses the mechanism and the specific VA rationale you're rebutting. See Supplemental Claim Guide.
  • Higher-Level Review (HLR): a senior reviewer looks at the same evidence again, useful if the denial rested on a legal error. See HLR Guide.
  • Board Appeal: your case goes to a Veterans Law Judge, with a direct review, evidence, or hearing docket. See Board Appeal Guide.

Not sure which lane fits? See the Appeals decision guide for a side-by-side comparison.

After You Win: Maintaining Your Rating

Keep documentation of ongoing treatment, follow-up evaluations, and any updated diagnostic testing for your degenerative arthritis on file, this protects you if VA schedules a future reexamination. See Protect Your Rating for when a rating becomes protected and Future Reexaminations for what triggers one. If your degenerative arthritis worsens, see the Rating Increase Guide.

Frequently Asked Questions

Does Ankle Limitation have to be highly rated to support a degenerative arthritis secondary claim?

No. 38 CFR 3.310 looks at whether the service-connected Ankle Limitation caused or aggravated the degenerative arthritis, not at how severe the Ankle Limitation rating is. Even a 0% service-connected primary can anchor a secondary claim.

What do the percentages on this page mean?

They are the historical outcomes of 459 published Board decisions on this exact pairing: 27% granted, 43% denied, 28% remanded. They describe decided appeals already on record. They do not predict what would happen in any individual case.
