Cosmetic effect of knee joint in a knee disarticulation prosthesis

Fred A. de Laat, MD, PhD, et al.

Patients with a knee disarticulation have a lengthened thigh and subsequent shortened lower leg due to the knee device built at the end of the upper leg. We show that the amount of thigh lengthening varies between 23 and 92 mm, depending on the knee device used, while lower leg shortening varies between 3 and 50 mm. The most favorable knee devices are polycentric, whereas microprocessor-controlled knees show less favorable characteristics because of their extended lengthening of the thigh.
