The anterior/posterior displacement in cruciate insufficient knee joint was measured. Both drawer tests were performed at 30 degrees of flexion in addition to 90 degrees of flexion, and the deta were statistically analyzed. The methods of loading a quantitative stress on the knee joint and a roentgenographic measurement were previously reported. In anterior cruciate insufficient knee, the anterior displacement was larger at 30 degrees of flexion than at 90 degrees. In posterior cruciate insufficient knee, on the contrary, the posterior displacement was larger at 90 degrees of flexion. The mean difference between complete and partial tear of each cruciate ligament was not statistically significant.
