摘要目的 探究21例股内侧肌下入路治疗膝关节外翻畸形的手术效果。方法 根据纳入及排除标准选取外翻畸形骨关节病患者21例,其中男6例,女15例。骨关节炎17例,类风湿性关节炎4例,年龄55~77岁,平均(63.51±3.47)岁,BMI数值均在20~26 kg/m2之间。术前评估患者膝关节活动度(range of motion,ROM)、胫股角(femorotibial angle,FTA)、膝关节评分(hospital for special surgery knee score,HSS)。同一主任医师行经股内侧肌下入路全膝关节置换手术,术后统一标准围手术期处置,康复出院后定期随诊,术后6个月评估患者ROM、FTA、HSS。结果 21例患者顺利完成膝关节置换,平均手术时间(95.00±4.60)min,术后第4天血红蛋白下降量(21.00±7.12)g/L,术前膝关节HSS评分(36.01±5.19)分,术后膝关节HSS评分(88.62±3.61)分,差异均有统计学意义(P<0.05)。术前膝关节外翻角(18.21±0.92)°,术后6个月膝关节外翻角(5.13±4.51)°,差异均有统计学意义(P<0.05)。术前膝关节活动度(85.35±3.11)°,术后6个月膝关节活动度(105.28±6.17)°,差异均有统计学意义(P<0.05)。结论 经股内侧肌下入路全膝关节置换手术治疗膝关节外翻畸形术后早期临床疗效较好,并发症较少。
