关节镜下膝前交叉韧带重建术疗效分析

目的：探讨自体中1／3骨－髌腱－骨（B－PT－B）重建前交叉韧带（ACL）的临床效果。方法：1996年9月－2000年10月对13例膝ACL损伤，其中男9例，女4例，年龄23－45岁。均采用关节镜下自体中1／3B－PT－B重建ACL，挤压螺钉固定，治疗CAL损伤后关节不稳定，术前抽屉试验13例均为阳性，轴移试验4例阳性，Lachman试验7例阳性，术后获随访5－25个月，平均15个月。结果：术后屉试验，轴移试验和Lachman试验均转阴性。按照Bosaotta的术后临床指标评价方法，优9例，良3例，可1例，所有患者均感膝关节稳定性明显改善。结论：关节镜下自体中1／3B－PT－B重建ACL损伤疗效显著。

EFFECT OF ARTHROSCOPIC ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION

Objective To investigate the clinical effect of reconstructing anterior cruciate ligament by using a bone patellar tendon bone autograft under arthroscopy. Methods Among 13 patients with anterior cruciate ligament injury, there were 9 males and 4 females(aged 23 45). Their anterior cruciate were reconstructed by applying the mid one third autologous bone patellar tendon bone strip in press fit technique under arthroscopy. The result was positive in 13 cases in anterior drawer test, in 4 cases in pivot shift test and in 7 cases in Lachman's test preoperatively. Results The follow up period was 5 25 months averaged 15 months. The results of the above tests were negative in all the patients. According to Boszotta's evaluation quota, the results were excellent in 9 cases, good in 3 cases and fair in 1 case. The knee stability improved obviously in all patients. Conclusion Anterior cruciate ligament injury can be treated by arthroscopic reconstruction with autologous bone patellar tendon bone strip and the clinical result of short term followup is satisfactory .
