Hip Limitation Claimed Secondary to Knee Instability

Hip Limitation (VA diagnostic code 5252) is sometimes claimed as secondary to service-connected Knee Instability (code 5257) under 38 CFR 3.310. This page reports what published Board of Veterans' Appeals decisions on that pairing show. It is an encyclopedic reference, not a forecast.

What published Board decisions show

Across 820 published Board (BVA) decisions in our index where hip limitation was claimed as secondary to knee instability, the outcomes broke down as follows. These are historical aggregates of decided appeals, not a prediction for any individual claim.

15%
Granted
52%

31%
Remanded
Granted 124Denied 426Remanded 256 (sent back for more development)

Counting only appeals that were granted or denied (setting aside remands), about 23% were granted. A remand is not a loss; it means the Board needed more evidence before deciding.

How this pairing works

A secondary claim says hip limitation flows from a service-connected knee instability. Whether the medical link exists in any one case is a medical question decided on that case's own evidence (the nexus). See the Secondary Claim guide.

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 hip limitation (the secondary).
  • A service-connected primary: Knee Instability, already service-connected (the primary). A 0% primary still counts.
  • A medical nexus: a medical opinion linking the hip limitation to the knee instability, 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.

Frequently Asked Questions

Does Knee Instability have to be highly rated to support a hip limitation secondary claim?

No. 38 CFR 3.310 looks at whether the service-connected Knee Instability caused or aggravated the hip limitation, not at how severe the Knee Instability 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 820 published Board decisions on this exact pairing: 15% granted, 52% denied, 31% remanded. They describe decided appeals already on record. They do not predict what would happen in any individual case.
