Gait analysis in peripheral vascular insufficiency through-knee amputation.

Due to recent improvements in prosthetic limb componentry, through-the-knee (knee disarticulation) amputation has gained new interest for rehabilitation-minded amputation surgeons. Recent objective scientific studies from our gait analysis laboratory have described the walking characteristics of peripheral vascular insufficiency through-knee amputees, and have compared their function with similar patients amputated above (transfemoral), or below (trans-tibial), the knee joint. This paper provides a summary of that available information.
