Abstract

A custom-made distal femoral replacement was instrumented to measure axial force, torque and bending moments in the prosthesis shaft. Data are reported for the following activities at 1 year post-op: walking, stair climbing and descending, jogging and jumping. Mean peak shaft axial forces were as follows: 3.1BW for jogging, 2.7BW for stair descending, 2.2BW for walking, 2.1BW for stair ascending. Bending moments about the AP and ML axes for these activities were in the range 6.3-8.3BWcm and 3.5-5.5BWcm respectively. Axial torques were between 0.9-1.4 BWcm, inwardly directed.
