Development of a ten-station, multi-axis hip joint simulator

This is the authors' abstract. We don't add key points for this paper.

Joint simulators are now used extensively to evaluate the performance of materials and designs of total replacement hip and knee joints. In this Technical Note a new ten-station hip joint simulator with biaxial rotational articulation synchronized to a physiological loading cycle is described. The current simulator manufactured by ProSim Limited (Manchester, UK) is a development of a first generation machine designed and built in-house at DePuy International Limited (Leeds, UK). The use of this new form of ten-station hip simulator to evaluate the performance of 22 mm zirconia femoral heads and ultra-high molecular weight polyethylene acetabular cups over some 7 million loading cycles is described elsewhere [1].
