Subtalar or tarsal joint ankylosis

To support a 20% rating, evidence would need to show that your subtalar or tarsal joint is fused and that the fixed position interferes with normal weight-bearing. This could come from imaging such as X-rays or CT scans confirming ankylosis, along with a physical examination documenting the exact angle or alignment of the foot and how that position affects your gait or your ability to stand. A VA or private examiner's description of why the position is poor for weight-bearing carries particular weight. For a 10% rating, the same imaging and examination findings would apply, but the records would reflect that although the joint is fused, the foot remains in a position that still allows functional weight-bearing. Statements from you or people who observe you daily about difficulty walking, pain while standing, or the need for assistive devices can help show how the fixed position affects your work and daily activities.
