前交叉韧带损伤术前膝关节稳定性测试

Preoperative Evaluation of the Knee Stability in Anterior Cruciate Ligament (ACL) Injury

比较６８例前交叉韧带损伤术前常规及麻醉下的前抽屉试验、Ｌａｃｈｍａｎ试验、膝外翻应力试验的结果，并用Ｓｔｒｙｋｅｒ膝关节仪做稳定性测试。前抽屉试验的阳性率为４４．１％，麻醉下为７９．４％；Ｌａｃｈｍａｎ试验的阳性率为８８．２％，麻醉下为９５．６％；膝外翻应力试验的阳性率为６６．２％。仪器测试结果阳性率为８２．４％。作者认为，Ｌａｃｈｍａｎ试验对于前交叉韧带损伤具有重要的诊断意义，仪器的稳定性测试可作为诊断的补充措施。

A prospective study was performed on 68 patients who were thought or suspected to have anterior cruciate ligament(ACL) injury. Each patient had a clinical examination preoperatively and under anesthisia.By Drawer test there were 44.1% of the cases positive and 79. 4% under anesthesia; By Lachman test there were 88.2% positive and 95.6% under anesthesia; Instrumented testing with Stryker arthrometer showed that 82.4% in positive results.This study suggests that the Lachman test is the most significant for evaluation of the knee stability and the most accurate way to determine ACL integrity. However, instrumented testing was benifical. In many cases, the clinical diagnosis was improved by instrumented confirmation.
