Genu recurvatum is a consequence of a poor control over the knee joint due to muscle weakness, impaired tonus and deficit in joint proprioception. Uncontrolled locking of the knee during ambulation causes recurrent microtrauma which leads to degenerative changes and instability. Known methods to control hyperextension of the knee during ambulation often fail. We have used the Swedish knee-cage attached to ankle-foot brace in an attempt to improve control over the knee in three patients. Gait analysis was performed to evaluate the effectiveness of this combined orthosis. Quality of gait improved, as demonstrated by a decrease in stance time asymmetry in the order of 45%; stride increased by 29% and speed of ambulation increased by 72%.
膝反屈是由于肌肉无力、张力受损和关节本体感觉缺陷导致膝关节控制不佳的结果。行走过程中膝关节不受控制的锁定会导致反复的微创伤，进而导致退行性改变和不稳定。已知的控制行走过程中膝关节过度伸展的方法往往无效。我们在三名患者中使用了连接到踝足矫形器上的瑞典膝关节固定架，试图改善对膝关节的控制。进行了步态分析以评估这种组合矫形器的有效性。步态质量得到改善，表现为站立时间不对称减少了约45%；步幅增加了29%，行走速度增加了72%。
