An Analysis of Human Knee Joint Motion for Anterior Cruciate Ligament reconstruction

Three dimensional joint motion data were obtained using precise magnetic sensors and X-ray. Six metal markers were inserted on the femur and the tibia to set the coordinate system. Two magnetic position sensors were used to record motion data and these positions were transformed into the knee motion. The quadriceps muscle was extended in an automatic manner by an extraction machine. Results of the knee motion were the same as the clinical data. The proposed method is found to be reasonable in describing the knee motion so that these motion data can be used to simulate the normal knee joint.
