Knee joint biomechanics for various ambulatory exercises was investigated using inverse dynamics in OpenSim, a computational platform for accelerated biomechanics research. A motion capture system was used to collect kinematic and kinetic information during walking, squatting, and the one-legged squat. Pre-processing of the data was accomplished using a MATLAB toolbox. Subsequent modeling, simulation, and analysis was performed in OpenSim. Loading in the cruciate ligaments and select muscles were the primary focus for the analysis. The accuracy of the results is compared with other available work in the literature. The impact, limitations, technology, and novelty were also reviewed in the scope of this work.
