The clinical outcomes of all patients were evaluated preoperatively, as well as at 1 year, 2 years, and 3 years postoperatively. The guidelines of the International Knee Documentation Committee (IKDC) were used to evaluate knee function and sport activity[44], while the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score was used to evaluate OA[45]. Scores obtained using visual analog scales (VAS) were also used to assess pain.
