Forty-two patients referred to the outpatient clinic of Hagavik Orthopaedic Hospital within 3 weeks after an acute knee injury was found by arthroscopy to have a partial or total tear of the anterior cruciate ligament (ACL). In these patients, the results of clinical tests and instrumented laxity tests without anesthesia prior to the arthroscopy were analyzed. The Lachman test and the maximum anterior pull (150-200 N) KT-1000 instrumented test revealed abnormal laxity in 33 and 37 of 42 cases, respectively. Both tests revealed abnormal laxity more often than the KT-1000 test using 67 N (10/42) and the maximum anterior pull KT-1000 instrumented test also revealed abnormal laxity more often than the KT-1000 test using 89 N (25/42). By logistic regression analysis, the maximum anterior pull KT-1000 instrumented test was associated with rupture of the ACL (partial or total rupture). The results show that adequate anterior pull has to be used to overcome muscle tension to reveal abnormal laxity in acute ACL tears using the KT-1000 arthrometer.
42例急性膝关节损伤患者在关节镜检查发现前交叉韧带（ACL）部分或完全撕裂后3周内转诊至哈加维克骨科医院门诊。对这些患者关节镜检查前未麻醉时的临床检查和仪器化松弛试验结果进行分析。拉赫曼试验和最大前拉（150 - 200 N）KT - 1000仪器化试验分别显示42例中有33例和37例存在异常松弛。这两种试验显示异常松弛的情况比使用67 N的KT - 1000试验（10/42）更常见，并且最大前拉KT - 1000仪器化试验显示异常松弛的情况也比使用89 N的KT - 1000试验（25/42）更常见。通过逻辑回归分析，最大前拉KT - 1000仪器化试验与ACL撕裂（部分或完全撕裂）相关。结果表明，使用KT - 1000关节测量仪检测急性ACL撕裂时，必须施加足够的前拉以克服肌肉张力来揭示异常松弛。
