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. 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. A plurality of anchoring elements may share a single upper layer.

Cartilage repair plug

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 prebricatable 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 orthopedic surgeons, which includes a variety of differently sized and shaped plugs, as well as a set of instruments for the procedure are also disclosed.

A suture anchor for facilitating the anchoring of soft tissue to a bony site includes a distal sharpened tip, and intermediate threaded section and a proximal drive head. The drive head is configured to receive a socket drive tool and has a suture-receiving eyelet formed therethrough. The threaded section is defined by a crest taper angle that is greater than the root taper angle.

Wedge screw suture anchor

An orthopedic interference screw for compression anchoring a bone graft in a bore formed in a bone mass. The interference screw includes a biocompatible body with a root. A screw thread is formed over substantially all of the root. The screw thread includes buttress structure on only one side of the screw thread so that forces applied to the screw thread from a side remote from the buttress structure will be buttressed by the buttress structure.
