A biomechanical analysis of the knee joint undergoing rehabilitation: a case study

The purpose of this study was to use cinematographic methodology for the biomechanical analysis of the knee joint as the joint underwent rehabilitation following surgical repair of the ligament structure. The biomechanical variables consisted of time percent values for four phases of a single gait cycle, velocity profiles of knee joint motion, and dynamic force determinations. These variables were evaluated prior to and at 3-week intervals during a 9-week rehabilitation program. The results found identifiable changes in each of the variables.
