Use of portable motion analysis system for knee stability assessment in ACL deficiency during single-leg-hop

摘要

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