The clinical and radiologic results of a gender-specific total knee arthroplasty design were compared with those of a conventional unisex design in 50 female patients with bilateral osteoarthritis and a minimum follow-up of 2 years. Total knee arthroplasty was performed using a conventional unisex implant in one knee and a gender-specific implant in the other. Clinical outcomes, which included range of motion, Hospital for Special Surgery scores, and Western Ontario and McMaster Universities Osteoarthritis Index scores, were compared. In addition, patients' subjectively preferred sides were noted, and radiologic results based on implant positions, posterior offsets, anterior offsets, and patellofemoral alignments were evaluated. No significant differences were observed between range of motion, Hospital for Special Surgery score, or Western Ontario and McMaster Universities Osteoarthritis Index scores. Patient subjective preferences and radiologic results were also similar for both sides. In conclusion, gender-specific knees in female total knee patients showed no advantages over standard unisex knees in terms of clinical or radiologic outcomes.
将性别特异性全膝关节置换设计的临床和影像学结果与 50 例双侧骨关节炎女性患者的常规通用设计进行比较，随访时间至少为 2 年。一侧膝关节使用常规通用植入物，另一侧膝关节使用性别特异性植入物进行全膝关节置换。比较了临床结果，包括活动范围、特种外科医院评分和西安大略省和麦克马斯特大学骨关节炎指数评分。此外，还记录了患者主观上更喜欢的侧别，并根据植入物位置、后偏移、前偏移和髌股关节排列评估了影像学结果。在活动范围、特种外科医院评分或西安大略省和麦克马斯特大学骨关节炎指数评分方面，两组之间均无显著差异。两侧的患者主观偏好和影像学结果也相似。总之，在临床或影像学结果方面，女性全膝关节置换患者的性别特异性膝关节并没有优于标准通用膝关节。
