摘要目的 分析第四代Oxford混合型单髁置换术治疗膝关节前内侧骨关节炎的短期临床疗效。方法 回顾性分析2020年10月至2021年9月就诊于江苏省中医院骨伤科的60例前内侧骨关节炎患者资料,均行第四代Oxford混合型单髁置换,其中男20例,女40例;年龄54~85岁,平均(68.43±7.04)岁;左膝32例,右膝28例;身体质量指数19.5~39.1 kg/m2,平均(25.68±3.55)kg/m2。记录术前和末次随访的疼痛视觉模拟评分(visual analogue scale,VAS)、美国特种外科医院(hospital for special surgery,HSS)评分、关节活动度(range of motion,ROM)及术后并发症,通过术前、术后X线片上的股胫角(femorotibial angle,FTA)评估内翻纠正程度。结果 60例患者术后均获随访,随访时间6~16个月,平均(11.40±2.94)个月。术后末次随访VAS评分为(0.37±0.48)分,HSS评分为(91.56±2.51)分,ROM为(117.83±7.83)°,术后FTA为(176.17±2.54)°。术后所有切口均Ⅰ级愈合,无关节感染,影像学显示假体对位、对线正常,未见假体周围骨折、松动和衬垫脱位。结论 第四代Oxford混合型单髁置换术治疗膝关节前内侧骨关节炎的短期疗效优良。
