System for ostechondral flap repair and method

摘要

A method of fixation of osteochondritis dissecans fragments in which chondral fragments are approximated to bone using a guide sleeve having multiple parallel guide tunnels. A drill is inserted through one of the guide tunnels, and a hole is drilled through the fragment and into the bone to a predetermined depth. A fragment-retaining implant inserted into the hole secures the fragment to the bone. Further holes are drilled while the fragment is held in place with the guide sleeve. The implant is inserted using the guide sleeve as a guide.
