One hundred subjects with normal knees and 47 patients with chronic rupture of the anterior cruciate ligament were tested in the Genucom Knee Analysis System; the 13 different laxity tests were carried out on both knees. Measurements on right and left knees in normal subjects showed that only the lateral pivot shift test, performed at 25 degrees of knee flexion, had a good side-to-side correlation, but did not differentiate the involved and uninvolved knees in the patients with anterior cruciate ligament deficiency. The sensitivity of the lateral pivot shift was 30% and specificity 91%. The corresponding figures for the anterior drawer test at 30 degrees flexion using 93 N force were 45% and 88%. Measurements showed great variation. Care should be taken in interpreting the results from the Genucom System. It should be considered as an experimental device with little value in assessing patients with anterior cruciate ligament deficiency.
100名膝关节正常的受试者和47例前交叉韧带慢性断裂患者在Genucom膝关节分析系统中接受测试；对双膝进行了13种不同的松弛度测试。正常受试者左右膝的测量结果表明，仅在膝关节屈曲25度时进行的外侧轴移试验具有良好的左右相关性，但在前交叉韧带损伤患者中无法区分患侧和未患侧膝关节。外侧轴移试验的敏感性为30%，特异性为91%。使用93 N力在30度屈曲时进行的前抽屉试验的相应数据分别为45%和88%。测量结果显示差异很大。在解释Genucom系统的结果时应谨慎。应将其视为一种实验设备，在评估前交叉韧带损伤患者方面价值不大。
