Abstract

UNLABELLED

Recent studies question an effect of gender on outcome of primary TKA. We questioned whether the results of revision TKA were affected by gender. We separated 67 revision TKAs by gender and preoperative diagnosis into four groups (arthrofibrosis, infection, instability, and wear and loosening). Each revision TKA was individually matched by age and gender to two primary TKAs. Postoperative Knee Society pain and function scores after revision TKA were lower than for primary TKA for both females and males. However, postoperative Knee Society pain and function scores were similar in males and females. Postoperative pain and function scores were lower for all revision groups compared with primary TKA, except for pain and function scores after revision for instability. Postoperative pain and function scores were higher for instability and wear or loosening than for arthrofibrosis. Our data suggest the results of revision TKA are affected by preoperative diagnosis but not gender.

摘要

未标注

近期研究对性别对初次全膝关节置换术(TKA)结果的影响提出质疑。我们探讨了翻修TKA的结果是否受性别影响。我们根据性别和术前诊断将67例翻修TKA分为四组(关节纤维化、感染、不稳定以及磨损和松动)。每例翻修TKA均根据年龄和性别与两例初次TKA进行个体匹配。翻修TKA术后的膝关节协会疼痛和功能评分在女性和男性中均低于初次TKA。然而,男性和女性术后的膝关节协会疼痛和功能评分相似。与初次TKA相比,除不稳定翻修术后的疼痛和功能评分外,所有翻修组的术后疼痛和功能评分均较低。不稳定以及磨损或松动组的术后疼痛和功能评分高于关节纤维化组。我们的数据表明,翻修TKA的结果受术前诊断影响,但不受性别影响。
