Instrumented knee laxity testing devices have been used in both the clinical and research setting to evaluate persons with injuries about the knee. The ability to accurately and reproducibly quantify knee motion has the potential to greatly benefit both clinical practice and research by improving the validity of the research involving treatment of knee-ligament injuries.
Systematic review; Level of evidence, 4.
A thorough literature review was performed, and a systematic overview is provided evaluating the methods of use and the evidence for the use of instrumented knee laxity testing devices.
Devices that provide measurements of knee laxity have evolved during the past 30 years. The authors describe in detail their proper use and the best estimates of their validity based on clinical studies.
The review suggests that the KT-1000 knee arthrometer and the Rolimeter provide best results when testing anterior laxity at the knee, whereas the Telos device is superior for the assessment of posterior laxity.
仪器化膝关节松弛度测试设备已在临床和研究环境中用于评估膝关节受伤的患者。准确且可重复地量化膝关节运动的能力，有望通过提高涉及膝关节韧带损伤治疗的研究的有效性，极大地造福临床实践和研究。
系统评价；证据等级，4级。
进行了全面的文献综述，并提供了系统概述，评估仪器化膝关节松弛度测试设备的使用方法和使用证据。
在过去30年中，提供膝关节松弛度测量的设备不断发展。作者根据临床研究详细描述了它们的正确使用方法及其有效性的最佳评估。
该综述表明，在测试膝关节前向松弛度时，KT-1000膝关节测松仪和旋转测量仪效果最佳，而Telos设备在评估后向松弛度方面更具优势。
