Abstract
A cartilage plug, which is made from a biocompatible, artificial material, that is used to fill a void in natural cartilage that has been resected due to traumatic injury or chronic disease is disclosed. Alternatively, the plug may be relied upon to anchor a flowable polymer to subchondral bone. The plug is prefabricatable in any size, shape, and contour and may be utilized either singly or in a plurality to fill any size void for any application. The plug may be formed of a laminated structure to match the physiological requirements of the repair site. Additionally, ridges may be formed about the periphery of each plug to facilitate its anchoring to surrounding cartilage, bone and/or adjacent plugs. A procedure for resecting damaged or diseased cartilage and for implanting a replacement plug or plugs according to this invention, as well as a set of instruments for effecting the procedure, and a self-contained system for orthopaedic surgeons, which includes a variety of differently sized and shaped plugs, as well as a set of instruments for the procedure are also disclosed.
