经关节镜下松解及术后康复活动治疗膝关节僵直

Arthroscopy release and rehabilitation exercises for the treatment of knee ankylosis

目的 探讨关节镜下松解及康复训练治疗外伤性膝关节粘连僵直的效果. 方法 20例膝关节粘连僵直行关节镜下松解,切除关节内粘连束带和瘢痕组织,分离和切断部分挛缩的股四头肌腱,术后早期行持续被动活动锻炼及间歇主动活动锻炼.结果 20例随访10～20个月,膝关节活动度从术前平均40°增至术后110°,无感染、皮肤坏死或骨折等并发症发生. 结论 关节镜下对关节内粘连组织进行充分松解损伤小、辅以适当的康复训练,恢复快,是治疗膝关节粘连的一种良好方法.

Objective To investigate the effect of arthroscopy release and rehabilitation exercises for the treatment of knee ankylosis. Methods 20 cases of knee ankylosis were undergone arthroscopy release, the intraarticular adhesion bands and scarred tissues were resected, and the contracture quadriceps were freed and cut off. Postoperative continuous passive motion and intermittent active exercises were allowed. Results 20 cases were followed up for 10 ～20 months. The rang of motion of knee was improved from 40°to 110°, with improvement of 70° on average. No infection, skin necrosis or fracture was found. Conclusions It is a good way to treat knee ankylosis with arthroscopy release of intraarticular adhesion and rehabilitation exercises, which requires minimal trauma and provides quick recovely.
