PURPOSE
The purpose of this study is to evaluate the Rolimeter knee tester (Aircast, Europe) as reliable and clinically sensitive tool for identifying and quantifying knee joint laxity utilising a sample of both known ACLD and normal knees.
METHODS
Thirty matched subjects (15 known ACLD and 15 normal subjects) were tested for knee joint laxity using the Rolimeter. Each subject was measured at both 90 degrees and 30 degrees of knee flexion, by each of the six investigators. This was then repeated again by all six investigators so that inter-tester and intra-tester reliability could be examined.
RESULTS
Results showed that there was good reliability between testers, and intra-tester reliability was good for both left and right knees in both 90 degrees and 30 degrees of flexion. Results also demonstrated a high level of sensitivity for determining knee joint laxity in ACLD compared to normal knees.
CONCLUSION
The Rolimeter knee tester is a reliable device for quantifying knee joint laxity, and is sensitive enough to identify anterior cruciate ligament deficiency.
目的
本研究旨在评估Rolimeter膝关节测试仪（欧洲Aircast公司）作为一种可靠且临床敏感的工具，用于利用已知前交叉韧带损伤（ACLD）和正常膝关节样本识别和量化膝关节松弛度。
方法
使用Rolimeter对30名匹配的受试者（15名已知ACLD受试者和15名正常受试者）进行膝关节松弛度测试。六名研究人员分别在膝关节屈曲90度和30度时对每名受试者进行测量。然后所有六名研究人员再次重复测量，以便检查测试者间和测试者内的可靠性。
结果
结果表明，测试者之间具有良好的可靠性，并且在90度和30度屈曲时，测试者内可靠性对于左右膝关节均良好。结果还表明，与正常膝关节相比，该测试仪在确定ACLD膝关节松弛度方面具有较高的敏感性。
结论
Rolimeter膝关节测试仪是一种用于量化膝关节松弛度的可靠设备，并且足够敏感以识别前交叉韧带损伤。
