Utility of a New Developed Motion Capture with Infrared Camera System in ACL-Insufficient Knees by the Comparison with the Validated Navigation System

Based on the quantification of a dynamic rotatory knee laxity reproduced and evaluated by the pivot-shift test, our newly developed noninvasive system (MCICS) could be as accurate as the validated navigation system, particularly within range of knee flexion during the pivot-shift test, which could be useful in diagnosis of ACL pathology and the postoperative evaluation of surgical reconstruction.
