Tips of the trade #28. Accurate tunnel placement using drill guides in knee ligament reconstruction.
Knee ligament reconstruction is optimized when intra-articular grafts are placed isometrically. Several drill guides have been designed to facilitate accurate tunnel placement. The use of an intra-articular keying hole, made with a burr, enhances proper and secure drill guide placement. Sterile mineral oil lubrication of the drill guide components will help prevent their distortion and will eliminate improper tunnel placement.
