摘要

Here, we showed that small misalignments of the patella relative to the femur change the joint contact mechanics substantially for a given external load. Therefore, understanding of the contact mechanics requires an accurate, 3-D geometry of the articular cartilage surface and the corresponding bone alignment and orientation, for in vivo joint movement and walking. This is a problem that has not been solved adequately for in vivo diarthrodial joints. Thus, contact models and simulations remain, at present, the best source for estimating the in vivo contact mechanics of real joints during normal, everyday movement.
