摘要
目的介绍在关节镜下利用绳肌肌腱和微型钢板纽扣重建后十字韧带(PCL)的方法,探讨其临床效果。方法对21例单纯PCL断裂的患者,在关节镜下利用绳肌肌腱和微型钢板纽扣进行重建,术后进行1年以上的随访,了解膝关节功能。结果术后3个月,所有患者均无伸膝受限,膝关节屈膝活动度均大于120°。术后1年,患肢的股四头肌-绳肌峰力矩比超过正常侧的90%;屈膝70°时后抽屉试验Ⅰ度阳性2例,其余均为阴性;屈膝30°时后抽屉试验Ⅰ度阳性6例,其余为阴性;膝关节功能Lysholm评分为90.7±2.3。结论在关节镜下利用绳肌肌腱和微型钢板纽扣重建PCL方法简单,能够可靠恢复膝关节功能。
Objective To study the clinical outcome of arthroscopic reconstruction of posterior cruciate ligament (PCL) with hamstring tendons and mini-plate and button. Methods From January 1998 to December 2000, 21 cases of PCL ruptures were reconstructed arthroscopically with five to seven strands of hamstring tendons and mini-plate and button. There were 14 males and 7 females aging from 27 to 49 years with the mean age of 36.4 years. All of the patients were free from posterolateral corner ligament injury. The interval from injury to diagnosis was 2.5 months ranging from 2 weeks to 15 months. There were 3 fresh and 18 old injuries. The patients were followed up for more than 12 months and were evaluated for knee function. Results No extension limitation occurred and the flexion degree were more than 120° in all cases 3 months postoperatively. One year after operation, the quadriceps-hamstrings peak torque ratio reached more than 90% of the uninjured leg; posterior drawer test at 70° flexion were negative in all but two cases who had one-degree instability; posterior drawer test at 30° flexion were one degree positive in six cases, and negative in other cases; the Lysholm knee score were 90.7±2.3. Conclusion Arthroscopic reconstruction of PCL with hamstring tendons and mini-plate and button is relatively simple and reliable for the restoration of knee function.
