A Biomechanical Comparison of Posterior Cruciate Ligament Reconstruction Techniques

摘要: Most posterior cruciate ligament reconstruction techniques use both tibial and femoral bone tunnels for graft placement. Because of the acute angle must make to gain entrance into tunnel, abnormal stresses are placed on that could lead failure. An alternative technique involves placement plug from anatomically back tibia (inlay), preventing formation an at attachment site. We used six pairs human cadaver knees compare biomechanical properties these two techniques. One knee each pair underwent tunnel while other inlay reconstruction. There was significantly less anterior-posterior laxity in group when compared with 30° 90° flexion after repetitive loading flexion. Evaluation grafts revealed evidence mechanical degradation but not group. The resulted translation than did
