Abstract

We treated a 17-year-old girl with post-infectious fibrous ankylosis of the left knee by geometric total knee replacement arthroplasty. Six months after the operation, the patient has slight pain and motion full extension to 110° flexion. Biomechanically and anatomically, a hinged metal-on-metal prosthetic knee does not allow for simulation of normal knee motion, including rotation. The successful developement of the total hip replacement has encouraged the developement of an equally successful total knee replacement. The use of polymethyl metacrylate to provide secure fixation of the component parts has provided a capability not possible with any previous system of total knee arthroplasty. Geometric or polycentric total knee arthroplasty represents a major advance in joint reconstruction; while, according to Coventry and Convery, the former is more promising.
