Abstract
Using published data on knee joint forces, the distribution of compressive forces on the tibial tracks of the polycentric knee was examined. The theory of a finite beam on an elastic foundation was applied to examine the tensile and compressive stresses acting on the cancellous bone foundation. Polycentric tibial tracks are available in standard (2. 54 cm) and extended 3. 81 cm) lengths. The extended track has superior stress distribution characteristics compared to the standard track, particularly for loads applied 5 mm or more from the track centers.
