Fixed rotation of either the femur or tibia has a significant influence on the patellofemoral joint contact areas and pressures. This is due to the anatomic asymmetry in the knee with respect to all planes, as well as the laterally directed force vector that naturally exists in bipedal lower-limb biomechanics. Specifically, femoral rotation results in an increase in patellofemoral contact pressures on the contralateral facets of the patella, and tibial rotation results in an increase in patellofemoral contact pressures on the ipsilateral facets of the patella. This difference can be elucidated when one considers that rotation of the femur is biomechanically different than rotation of the tibia. For both tibial and femoral rotations, the patella's distal attachment to the tibial tubercle influences the direction of patellar movement. The biomechanical evidence reviewed in this manuscript suggests that the determining factor in patellofemoral pathology is the derangement of normal joint mechanics. However, despite considerable experimental data supporting this position, there also are theories that suggest otherwise. This illustrates a very important point in patellofemoral joint pathology, where no one factor may be the sole defining etiology. Instead, the patellofemoral joint is one of the most complex diarthrodial joints in the body and there are a number of etiologic factors that can lead to pathology. This should be considered for developing repair and rehabilitation strategies.

“…Bresler and Cappozzo et al studied the joint moment during gait using a mechanical model [17,18]. Most of studies have since analyzed normal gait [19][20][21][22] or severe gait disturbance cases [23][24][25], and few were focused on coxarthrosis. It was difficult to evaluate the complex waveform of the joint moment in coxarthrotic patients.…”

Summary: I report the results from gait analysis for coxarthrotic patients using a ground reaction force plate and a three-dimensional motion analysis system. Twenty-seven coxarthrosic patients , and 9 healthy females as controls, participated in this study. The waveform of the ground reaction force and the joint moment during the stance phase were evaluated. The waveform of the hip joint moment changed and flattened in both pre-coxarthrosis and early-coxarthrotic patients, compared to those in controls, indicating that coxarthrotic patients adopted a particular gait pattern to reduce the load on the affected hip joint. Beyond X-ray observations and physical examinations, joint moment analysis could achieve a more objective evaluation of the clinical stage of coxarthrosis .
