Three designs of knee braces were investigated in 21 knees with arthroscopically verified old tears of the anterior cruciate ligament. Anterior-posterior and rotatory instability with and without anterior traction were recorded with roentgen stereophotogrammetric analysis. Two of the designs examined reduced the anterior-posterior instability (ECKO, modified Lenox Hill), but not to normal levels. At 20 degree of flexion, none of the braces decreased the internal rotatory instability, whereas one type (modified Lenox Hill) reduced the external rotatory instability.
对21例经关节镜证实存在前交叉韧带陈旧性撕裂的膝关节，研究了三种膝关节支具设计。通过X线立体摄影测量分析记录了有无前牵引时的前后向和旋转不稳定情况。所检查的两种支具设计（ECKO、改良的莱诺克斯山支具）可减轻前后向不稳定，但未降至正常水平。在屈膝20度时，没有一种支具能降低内旋不稳定，而有一种类型（改良的莱诺克斯山支具）可降低外旋不稳定。
