Figure 7

Case studies. Four examples of varying first-visit severity were selected, illustrating cases where our models suggest limbs were (A) under-treated, (B) appropriately surgically treated, (C) potentially over-treated, and (D) potentially conservatively treated. Horizontal colored bands represent 95% confidence interval for range of expected outcomes without (orange) and with (blue) surgery. Black squares represent GDI at first gait visit, and colored dots represent GDI at follow-up gait visit.
