PurposeThe目前的文章总结了一个简单的，客观的，和非侵入性的胫股旋转测量设备的发展，以评估静态旋转膝laxity.Methods和resultsThe设备是基于拨号测试与患者俯卧和膝关节屈曲30°。从30名健康参与者的测量结果来看，该设备实现了较高的观察者间和观察者内可靠性，并显示出测量结果与参与者对侧膝关节的高度相关性。还在人体尸体研究中进行了器械测量，与膝关节导航系统的同步测量相比，显示了高度相关的结果，膝关节导航系统用作评估胫骨旋转的有创标准方法。在人尸体标本中，结果表明，与完整ACL相比，后外侧束的模拟撕裂以及ACL完全撕裂导致单独胫股旋转显著增加。一项回顾性病例系列研究了体内ACL手术后的临床结果以及膝关节松弛度测量值。在平均27个月的术后随访中，通过将测量结果与每例患者对侧未受影响膝关节的结果进行比较，对52例患者的旋转以及前后（AP）膝关节松弛进行了客观评估。临床结果与文献中报告的结果相当。此外，旋转松弛成功恢复后ACL重建，而AP松弛显示出显着差异相比，对侧膝关节，虽然他们被定义为临床成功根据IKDC classification.ConclusionsA非侵入性和客观的膝关节旋转测量设备已开发，这提供了良好的潜力，客观质量控制膝关节韧带损伤及其治疗。四级。
PurposeThe present article summarizes the development of a simple, objective, and non-invasive measurement device for tibiofemoral rotation to assess static rotational knee laxity.Methods and resultsThe device is based on the dial test with the patient lying prone and the knee flexed to 30°. From measurements of 30 healthy participants, the device achieved high inter- and intra-observer reliability and showed a high correlation of the measured results with the contralateral knees of the participants. Measurements of the device were also performed in a human cadaver study and revealed highly correlated results when compared to the simultaneous measurements of a knee navigation system, which was used as an invasive standard method to assess tibial rotation. In human cadaver specimens, it was shown that a simulated tear of the posterolateral bundle as well as a complete ACL tear led to a significant increase in isolated tibiofemoral rotation compared to the intact ACL. A retrospective case series investigated the clinical results as well as knee laxity measurements after ACL surgery in vivo. Rotational, as well as anteroposterior (AP), knee laxity was objectively assessed in 52 patients at a mean postoperative follow-up of 27 months by comparing the measured results with the results of the contralateral unaffected knee in each patient. The clinical results were comparable to the results reported in the literature. Moreover, rotational laxity was successfully restored after ACL reconstruction, whereas AP laxity showed significant differences compared to the contralateral knees although they were defined as clinically successful according to the IKDC classification.ConclusionsA non-invasive and objective knee rotational measurement device has been developed, which offers good potential for objective quality control in knee ligament injuries and their treatment.Level of evidenceReview article, Level IV.
