ABSTRACT:
An adjustable drill guide for marking a proper location of a bone tunnel for arthroscopic surgery. The drill guide includes an arc shaped outrigger, an adapter slidably coupled to the outrigger, a plurality of interchangeable marking hooks adapted to be received by said adapter, and a sighting device coupled to the outrigger. The sighting device is adapted to receive a guide pin for marking the tunnel position. One of the plurality of marking hooks is chosen and inserted into the adapter of the outrigger. The adapter is then slid along the outrigger to a marked position at which an angled tip of the marking hook becomes aligned with the sighting device. Next, the marking hook is inserted into the knee requiring surgery. The sighting device is then advanced towards the knee until it is directly adjacent the knee. A guide pin is inserted into the sighting device and drilled into the knee. The drill guide is removed, thereby leaving the guide pin in position for drilling the tunnel.
