Background:
Good clinical and radiographic short-term results have been reported for patients who underwent realignment surgery of the hindfoot for treatment of early- and mid-stage ankle osteoarthrosis (OA). However, no mid- to long-term results have been reported. The aim of this study was to gain a better insight into the indications and contraindications for realignment surgery.
Methods:
Two hundred ninety-four patients (298 ankles) underwent realignment surgery between December 1999 and June 2013. Kaplan-Meier survival analysis was performed with total ankle replacement and arthrodesis of the ankle joint as endpoints. A Cox proportional hazards model was performed to identify risk factors for failure. The mean time to follow-up was 5.0 ± 3.7 years.
Results:
The overall 5-year survival rate was 88%. Thirty-eight patients (12.9%) underwent either secondary total ankle replacement or ankle arthrodesis (30 total ankle replacements, 8 ankle arthrodesis). Risk factors for failure following realignment surgery were age at the time of surgery and a Takakura score of 3b preoperatively.
Conclusion:
Realignment surgery of the hindfoot was an excellent treatment option for young and physically active patients with early to mid-stage ankle OA.
Level Of Evidence:
Level IV, prospective observational study.
