Abstract

The pivot-shift test is an important examination to assess the rotational laxity in the anterior cruciate ligament (ACL) injured and reconstructed knees. Because this examination is related to subjective knee function, we may still see cases that have residual rotational laxity after ACL reconstruction. Quantitative evaluation of the pivot-shift test is preferable to the clinical pivot-shift test but is difficult to attain mainly due to complicated movements of the pivot-shift. The electromagnetic tracking system was developed to evaluate knee kinematics during the pivot-shift, providing information related to 6-degree-of-freedom knee kinematics with a high sampling rate. Through this device, the abnormal movement of the pivot-shift is characterized in two phases: an increased anterior tibial translation and a boosted acceleration of tibial posterior reduction. Since its invention, this system has been utilized to assess rotational laxity for clinical follow-up and research after the ACL reconstruction.
