ACL Reconstruction with Biologic - synthetic Composite Graft using Bone Patellar Tendon Bone and Kennedy - LAD in Chronic Injury

• Jeong HJ

Abstract

This study was designed to evaluate the results of anterior cruciate ligament(ACL) reconstructions with ligament augmentation device(Kennedy LAD; 3M Co., St. Paul, MN, USA) in chronic injury. Eighteen patients with chronic ACL insufficiency were treated by ACL reconstruction using bone- patellar tendon-bone/LAD composite graft. The patients were followed up more than 5 years and the lat- est follow-up results are presented here. Evaluations were based on the Lysholm functional score, Lachman test and pivot-shift test. Data were analysed using the SPSS software. There were 9 patients(50%) with a Lysholm score more than 84(excellent or good) at latest follow-up. This postoperative improvement of Lysholm score was sta- tistically significant, P=0.001. There was no serious perioperative complications. Rehabilitation was not prolonged. This study demonstrated that a synthetic graft augmentation may improve results. However, no significant advantages have been observed with the use of LAD to augment patellar tendon. The com- parison study of ACL reconstruction with and without Kennedy LAD is recommended to assess the possi- ble effects of the addition of the LAD. And routine use of LAD should not be advocated in uncomplicated reconstruction of ACL using biological graft.
