臀肌松解术治疗臀肌挛缩导致膝骨性关节炎52例临床分析

目的：探讨臀肌挛缩松解术对预防臀肌挛缩症导致膝骨性关节炎发生的临床疗效与意义。方法：回顾性分析2008年1月至2010年6月收治的臀肌挛缩导致膝骨性关节炎患者52例,男15例,女37例;年龄15～45岁,平均35岁;左侧18例,右侧30例,双侧4例。本组52例均进行臀肌挛缩松解术。术后采用Lysholm膝关节功能评分对患者术前、术后客观结果进行评估。结果：52例均获随访,时间12～37个月,平均15个月,Lysholm膝关节功能评分由术前平均（68.12±0.78）分改善为术后末次随访时的（91.23±0.47）分,术后评分提高（t=31.269,P〈0.01）。结论：臀肌松解术能有效缓解臀肌挛缩症及膝骨性关节炎的症状。臀肌挛缩症的患者,早期治疗可以有效防止臀肌挛缩对膝关节的力学影响,减缓膝关节的早期退变,预防膝骨性关节炎。

Gluteal muscle contracture release for the treatment of gluteal muscle contracture induced knee osteoarthritis:a report of 52 cases

Objective: To investigate clinical efficacy and significance of gluteal muscle contracture release for the treatment of gluteal muscle contracture induced knee osteoarthritis. Methods: From January 2008 to June 2010,52 patients with gluteal muscle contracture induced knee osteoarthritis were reviewed. Among the patients,15 patients were male and 37 patients were female,ranging in age from 15 to 45 years,with an average of 35 years. Eighteen patients had left knee osteoarthritis,30 patients had right osteoarthritis,and 4 patients had double knee osteoarthritis. All the patients were treated with gluteal muscle contracture release. Lysholm knee score was used to evaluate therapeutic effects before and after operation. Results: All the patients were followed up,and the duration ranged from 12 to 37 years,with a mean of 15 months. The Lysholm knee score improved from preoperative(68.12±0.78) points to postoperative(91.23±0.47) points at the last follow-up,the difference had statistical difference(t=31.269,P<0.01). Conclusion: Gluteal muscle contracture release is effective to relieve symptoms of gluteal muscles contracture and knee osteoarthritis. The patients with gluteal muscle contracture should be treated early so as to prevent effects of gluteal muscle contracture on knee joint,slow down degeneration of knee joint at early stage,and prevent occurrence of knee osteoarthritis.
