A prospective study investigates anterior knee laxity in 100 healthy subjects (mean age 24.5 years). Testing was performed by two examiners either clinically by Lachman test or by means of KT-1000 arthrometer. Mean anterior tibial translation was 4 mm for the right and 4.3 mm for the left knee when tested clinically. With use of KT-1000 at 89 Newton results were 4.6 mm and 4.0 mm, respectively. Clinical measurements revealed an inter-examiner difference of 0 to 1 mm in 77% of right and 80% of left knees. In the remainder difference was more than 1 mm. On apparative testing the two examiners obtained similar results at 67 Newton. Measurements differed increasingly, however, at 89 Newton and 134 Newton. In conclusion, the use of KT-1000 arthrometer in routine assessment of anterior knee laxity offers no advantage over clinical testing alone.
一项前瞻性研究对100名健康受试者（平均年龄24.5岁）的膝关节前侧松弛度进行了调查。测试由两名检查者进行，临床检查采用拉赫曼试验，或使用KT-1000关节测量仪。临床测试时，右膝平均胫骨前移为4毫米，左膝为4.3毫米。使用KT-1000在89牛顿力时，结果分别为4.6毫米和4.0毫米。临床测量显示，77%的右膝和80%的左膝检查者间差异为0至1毫米。其余的差异超过1毫米。在仪器测试中，两名检查者在67牛顿力时获得了相似的结果。然而，在89牛顿力和134牛顿力时，测量结果差异越来越大。总之，在膝关节前侧松弛度的常规评估中，使用KT-1000关节测量仪并不比单纯的临床测试更具优势。
