Ten patients with chronic lateral instability of the ankle have been treated by operation using a homograft of preserved skin and scar tissue to reinforce the lateral ligament complex. The technique is simple and cheap. We have analysed the functional stability of the ankles after operation by E. M. G. and Cybex studies of the appropriate muscle groups when standing on an unstable platform and during normal gait. The passive tension of the ligaments is of greater value in stabilising the ankle than active contraction of the muscles. The peroneus brevis has an important action in opposing varus stress, and should be preserved rather than used for ligament substitution.
10例慢性踝关节外侧不稳定患者接受了手术治疗，采用保存的皮肤和瘢痕组织同种异体移植来加强外侧韧带复合体。该技术简单且成本低廉。我们通过肌电图（EMG）以及在不稳定平台上站立和正常步态期间对相应肌肉群进行Cybex研究，分析了术后踝关节的功能稳定性。韧带的被动张力在稳定踝关节方面比肌肉的主动收缩更有价值。腓骨短肌在对抗内翻应力方面有重要作用，应予以保留而非用于韧带替代。
