Retrospective comparison of total ankle arthroplasty with patient-specific instrumentation and ankle arthrodesis for patients with end-stage ankle arthritis and preoperative degeneration of adjacent joints
This retrospective study demonstrates that total ankle arthroplasty with patient-specific instrumentation yields superior functional outcomes and preserves ankle motion compared to ankle arthrodesis in patients with end-stage ankle arthritis and preoperative adjacent joint degeneration, without increasing complication rates or accelerating peritalar joint progression at short-term follow-up.
