Pitfalls in the use of interference screws for anterior cruciate ligament reconstruction: brief report
1Union Memorial Hospital Department of Orthopaedic Surgery, Johns Hopkins University School of Medicine, Baltimore, Maryland 21218.
Abstract:
Arthroscopically assisted bone patellar tendon bone reconstruction of the anterior cruciate ligament (ACL) is becoming an increasingly popular surgical technique. Use of interference screw fixation of the bone plugs within bony tunnels has been shown to improve fixation and pull-out strength. Several potential pitfalls exist which can jeopardize results of the surgical procedure when this form of fixation is used. This article describes the potential pitfalls and suggests methods to avoid them.
