The HAKI technique of femoral interference screw insertion.

Abstract

We describe a simple and reliable technique, the HAKI technique, of femoral interference screw fixation that can reduce surgical complications. In 83 ordinary endoscopic anterior cruciate ligament (ACL) reconstructions and 110 ACL reconstructions with our new technique, surgical complications related to the femoral interference screw fixation were evaluated. With our new technique, only one complication occurred while overall complications of 15.7% occurred in the ordinary group. Compared with the ordinary technique group, which had an average of 12.0 degrees screw divergence on anteroposterior radiographs and 13.5 degrees on lateral radiographs, our new technique had a significantly lower incidence of femoral screw divergence, with 8.0 degrees and 8.3 degrees on the anteroposterior and lateral views, respectively. This new technique could reduce a significant portion of complications that occur during endoscopic (single incision) bone-patellar tendon-bone ACL reconstruction.
