摘要 目的:探讨单侧全膝关节置换术中髌骨缩小联合外侧支持带松解在退行性膝骨关节炎患者中的应用。 方法:对 98 例退行性膝骨关节炎患者的临床资料进行回顾性分析,按照手术方法不同分为A 组(n=45)和 B 组(n=53)。 A 组在单侧全膝关节置换术中行髌骨缩小联合外侧支持带松解,B 组在术中行髌骨缩小。 比较两组膝前痛及髌骨轨迹不良发生情况、手术前后膝功能、髌骨功能、并发症发生率。 结果:A 组膝前痛发生率 6.67%低于 B 组 22.64%(P<0.05);术后 1 年,A 组膝关节协会评分(KSS)、髌骨评分(Feller)高于 B 组(P<0.05);两组并发症发生率比较,差异无统计学意义(P>0.05)。结论:单侧全膝关节置换术中髌骨缩小联合外侧支持带松解可以减少退行性膝骨关节炎患者膝前痛的发生,改善膝关节功能及髌骨功能,安全性较好。

Abstract Objective: To investigate the application of patella reduction combined with lateral retinacular release to patients with degenerative osteoarthritis(DOA)of knees during unilateral total knee arthroplasty (TKA). Methods: The clinical data of 98 patients with TKA were retrospectively analyzed, and the patients were divided into two groups according to different surgical methods: Group A(n=45)and Group B(n=53). Group A underwent patella reduction combined with lateral retinacular release during unilateral TKA, while Group B received patella reduction during unilateral TKA. Then, the incidence of anterior knee pain and poor patella track, knee and patella functions, and the incidence of complications before and after surgery were compared between the two groups. Results: The incidence of anterior knee pain in group A was lower than that in group B (6.67% vs 22.64%) (P<0.05); one year after surgery, knee society score(KSS)and patella score(Feller)in group A were higher than those in group B(P<0.05); and there was no significant difference in the incidence of complications between the two groups(P>0.05). Results: In unilateral TKA, the application of patella reduction combined with lateral retinacular release can reduce the incidence of anterior knee pain in patients with DOA of knee, improve knee and patella functions, without increasing the incidence of complications in patients.

Keywords: total knee arthroplasty(TKA); patella reduction; lateral retinacular release; degenerative osteoarthritis(DOA)of knee
