关节镜下治疗股骨髁间窝退变性狭窄症

目的探讨关节镜监视下股骨髁间窝狭窄症的疗效。方法自2001年6月～2006年6月通过关节镜下诊断和治疗股骨髁间窝退变性狭窄症59例。所有病例均行镜下股骨髁间窝扩大成形术，18例行前交叉韧带紧缩术，以Lysholm评分评价比较手术前后膝关节功能。结果镜下所见：股骨髁间窝外侧髁骨突撞击46例，内侧髁骨突撞击5例，内、外侧髁均撞击5例，髁间窝前缘撞击3例；受撞击前交叉韧带相应部位有不同程度的磨损及纤维断裂。52例获得15．48个月随访，术后检查患者关节屈伸功能基本正常，根据Lysholm评分系统评估关节功能，关节功能由术前76．5±4．5提高到96．7±3．8，差异有统计学意义（T=4．874，P〈O．05）。结论关节镜技术具有损伤小、术后康复快、疗效确切等优点，是诊治股骨髁间窝退变性狭窄症最直接有效的手段。

Arthroscopy in the treatment of degenerative stenosis of femoral intercondylar fossa

Objective To investigate the efficacy of the arthroscopy in diagnosis and treatment of degenerative stenosis of femoral intercondylar fossa. Methods From June 2001 to June 2006, 59 patients with degenerative stenosis of femoral intercondylar fossa were diagnosed and treated arthroscopically. All patients underwent arthroscopic femoral intercondylar fossa enlarging plasty, 18 patients underwent contraction of anterior cruciate ligament.According to Lysholm score criteria,the knee joint function was compared before and after operation. Result Arthroscopic finding：femoral lateral condyle impact in 46 cases, medial condyle impact in 5 cases, medial and lateral condyles impact in 5 cases, anterior edge of the intercondylar fossa impact in 3 cases.The ACL corresponding parts had different degrees of wear and fiber breakage.52 cases were followed for an average of 15-48 monthes. The fundamental function of joint was normal. The Lysholm score was increased from 76.5± 4.5 to 96.7±3.8.It＇s difference had statistical significanee（t=4.874,P〈0.05）. Conclusion Arthroscopy is the most direct and effective means and it has advantages of less trauma,quicker rehabitation and confirmed efficacy. In diagnosis and treatment of femoral intercondylar fossa stenosis syndrome.
