We assessed the relative restraints that are provided by fourteen currently available functional knee-braces, using six limbs in cadavera. The tests were made at 30 and 60 degrees of flexion of the knee, and a mechanical loading system applied loads that caused anterior-posterior translation and internal-external rotation. The braces limited abnormal tibiofemoral displacements by 10 to 75 per cent in translation; there was more variation in rotation. This study demonstrated that functional knee-braces provide a restraining influence that may be beneficial in the control of abnormal displacements of the knee, but that the degree of restraint varies considerably.
我们使用六具尸体的肢体，评估了十四种目前可用的功能性膝关节支具所提供的相对约束作用。测试在膝关节屈曲30度和60度时进行，一个机械加载系统施加导致前后平移和内外旋转的载荷。这些支具在平移时将异常的胫股位移限制了10%至75%；在旋转方面的变化更大。这项研究表明，功能性膝关节支具提供了一种约束作用，这可能有助于控制膝关节的异常位移，但约束程度差异很大。
