Utilization of portable motion capture system for knee stability assessment in ACL-deficiency during stair descent

摘要

Background: Recently, there have been various surgical techniques seeking to preserve the remnants of anterior cruciate ligament (ACL) in the knowledge that these remnant bundles play animportant role in graft healing process, proprioception preservation as well as biomechanicalstability. Surgeons try to preserve ACL remnants maximally for better clinical outcomes ofACL reconstruction. But remnant preservation technique has a problem like poor arthroscopicview to search for proper tunnel position. Therefore, we compared clinical results and tunnelpositions between splitting remnant preservation technique, non-splitting remnant preservationtechnique and remnant non-preservation technique by three-dimensional computed tomography.
