Knee & Hip Conditions Secondary to Flat Feet

The recognized connection, the three-legged evidence standard, and the free routes to the medical opinion.

← All secondary claims · Ratings by condition

A secondary claim is a condition caused or worsened by one the VA has already service-connected. The causation fight is already half-won — the VA agreed your flat feet came from service; the question is only whether it caused the knee & hip conditions. That's a medical question with a recognized answer.

The connection

Altered biomechanics travel up the chain: flat feet or plantar fasciitis change how you stand and stride, and years of that altered gait load the knees, hips, and low back abnormally. Podiatric and orthopedic literature both document the cascade — which is why a service-connected foot condition so often anchors claims for everything above it.

How the VA rates knee & hip conditions

Knee: instability (5257) and limitation of motion (5260/5261) can STACK — a rare double-dip the VA allows.

What the claim needs — the three legs

  1. The anchor: service connection for the flat feet (see how that condition is rated). Not connected yet? File it first — a secondary claim needs something to attach to.
  2. A current diagnosis of knee & hip conditions — the VA rates diagnosed conditions, not symptoms.
  3. The medical link. An opinion stating it is "at least as likely as not" that the flat feet caused or aggravated the knee & hip conditions. The VA's own C&P examiner supplies this free in most cases; your own doctor can too. A paid independent opinion is the last resort, not the first move.
Honesty note: nothing here is a promise of any rating — the VA decides every claim on its own evidence. What this page describes is a recognized medical pathway and the evidence standard that applies to it. Describe your real symptoms, including your worst days, accurately — never more, never less.
