The ideal graft for use in anterior cruciate ligament reconstruction should have structural and biomechanical properties similar to those of the native ligament, permit secure fixation and rapid biologic incorporation, and limit donor site morbidity. Many options have been clinically successful, but the ideal, graft remains controversial. Graft choice depends on surgeon experience and preference,...
This study presents a new method to estimate 3-D linear accelerations at tibial and femoral functional coordinate systems. The method combines the use of 3-D accelerometers, 3-D gyroscopes and reflective markers rigidly fixed on an exoskeleton and, a functional postural calibration method. Marker positions were tracked by a six-camera optoelectronic system (VICON 460, Oxford Metrics). The purpose...
Results of the analysis of the gait of patients suffering from osteoarthritis in their hips are reported, showing the feasibility of an assessment of individual arthritic gait. The results were used to develop a method for assessing dynamic mechanical factors that engender or limit knee osteoarthritis. A routine for the measurement of the instantaneous center of rotation has been developed and tested...
