摘要目的〓探究微创单髁置换术治疗膝关节自发性骨坏死的临床效果。方法〓回顾性分析2020年1月至2022年1月菏泽市单县中心医院采用人工单髁置换术治疗的49例膝关节自发性骨坏死患者,男29例,女20例;年龄43~57岁,平均(49.34±3.98)岁。根据选择的平台类型分成固定平台组21例和活动平台组28例。结果〓活动平台组住院时间和住院费用明显低于固定平台组(P<0.05);术后1 d及术后1个月,两组美国膝关节协会评分(knee society score,KSS)、美国特种外科医院(the hospital for special surgery,HSS)、疼痛视觉模拟评分(visual analogue scale,VAS)和疼痛数字模拟评分(numeric rating scales,NRS)评分比较,活动平台组明显优于固定平台组(P<0.05);两组术前和术后的解剖股胫角、胫骨后倾角、解剖轴股骨远端外侧角和解剖轴胫骨近端内侧角比较,差异无统计学意义(P>0.05)。活动平台组患者的垫片脱位率明显高于固定平台组(P<0.05),其余早期和晚期并发症两组差异无统计学意义(P>0.05)。结论〓活动平台微创单髁置换术治疗膝关节内侧自发性骨坏死可以取得更佳的早期效果。
