臀肌挛缩症伴膝前疼痛的病因分析及意义

目的: 探讨臀肌挛缩症伴膝前疼痛的病因及关节镜松解术对该症的临床疗效.方法: 自 2002年3月至2013年8月收治臀肌挛缩症合并膝前疼痛患者36例,其中男15例,女21例;年龄9～40岁,平均(18.7±7.2)岁;病程4～30年.临床表现为并腿受限、Ober征阳性、臀部可触及挛缩带,下蹲活动时膝关节髌骨伴向外侧滑动感等.所有患者行关节镜下臀肌挛缩松解术.观察患者术后并发症情况,并比较手术前后Kujala评分.结果: 术后36例均获得随访,平均随访时间29个月,切口均愈合良好,未见并发症.术后较术前Kujala评分各项指标均有提高.结论: 臀肌挛缩松解术可以缓解髌骨外侧高压症,对髌股关节炎具有预防意义.

Etiological analysis and significance of anterior knee pain induced by gluteal muscles contracture

Objective: To explore causes of gluteal muscle contracture induced anterior knee pain and curative effect of arthroscopic release.Methods: From March 2002 to August 2013,36 patients with gluteal muscle contracture induced anterior knee pain were treated,including 15 males,21 females,aged from 9 to 40 years old with an average(18.7±7.2) years old;the courses of diseases ranged from 4 to 30 years. The clinical manifestations invloved limited to symmelia,positive Ober sign,buttocks touch contracture belts,knee and patella slide to lateral when doing squat activities. All patients were performed gluteal muscle contracture release under arthroscopic. Postoperative complications were observed,Kujala scoring before and after operation was used for compare curative effect.Results: All patients were followed up with an average of 29 months. The incision were healed well,and no complications were occurred. Postoperative Kujala score were improved more than preoperative.Conclusion: Gluteal muscle contracture release could alleviate hypertension of lateral patella,and palys an important role in preventing patellofemoral arthritis.
