Analysis of Failed Cases of Anterior Cruciate Ligament Reconstruction of the Knee with the Bone-Tendon-Bone Method

概要

Fifty-one anterior cruciate ligament reconstructions were performed using the bone-tendon-bone method from April 1991 through March 1996. In these 51 cases floor plasty was not performed in 23 cases, of which 12 cases were judges to be failed ACL reconstructions because of instability of 3 mm or greater relative to the healthy knee and confirmation of rupture with arthroscopy. These 12 cases of failed reconstruction (in 2 men and 10 women) were 6 cases of femoral tunnel (notch), 1 case of femur-side K-screw tip, 3 cases that can be considered tibia tunnel remodeling, and 2 cases that can be attributed to the tibia-side K-screw.<BR>To prevent these failures measures, such as thorough formation of the notch, posteriorly shifting the opening of the tibial articular facet tunnel hole, implementing floor plasty, and development of a non-tapered interference screw, should be considered.
