The invention provides a method of correcting numerous bone abnormalities including bone tumors and cysts, avascular necrosis of the femoral head, tibial plateau fractures and compression fractures of the spine. The abnormality may be corrected by first accessing and boring into the damaged tissue or bone and reaming out the damaged and / or diseased area using any of the presently accepted procedures or the damaged area may be prepared by expanding a bag within the damaged bone to compact cancellous bone. After removal and / or compaction of the damaged tissue the bone must be stabilized.

Techniques and reconstruction systems for ACL repair by providing cross-pin fixation of a graft within a tibial tunnel. The invention provides tibial fixation techniques according to which cross-pin fixation of a graft (for example, an Anterior Tibialis allograft) is achieved on the tibial side, close to the jointline, by a single incision and with cortical fixation.

This invention provides for a novel orthopedic prosthesis, specifically a prosthetic tibial component for a prosthetic total knee joint, that comprises two constructs, one being a metal base construct that engages the bone and the other being a polyethylene bearing construct that attaches to the metal base construct and articulates with a femoral prosthetic component on the opposing side of the joint. The metal base construct is composed of two different metals, one of which engages the bone surface and the other of which engages the polyethylene bearing construct. Each of these metals is selected so that its characteristics are well suited to its particular function. More particularly, the first metal (i.e., the one that engages the bone surface) is selected so as to provide a superior bone-engaging face, while the second metal (i.e., the one that engages the polyethylene bearing construct) is selected so as to provide a superior polyethylene-engaging face. By combining the different material characteristics of two different metals in the metal bone construct, it is possible to simultaneously form a superior bone-engaging face and a superior polyethylene-engaging face.

A device for positioning a tibial tunnel during ACL reconstruction, the device that includes an elongated body having proximal and distal ends; and a distal arm extending from the distal end of the elongated body, a distal portion of the distal arm being configured for insertion into a pre-formed opening in a femur. The distal arm and the body are not aligned relative to each other when viewed from above. A pair of such devices, providing tunnel positioning for right and left knee surgeries, maybe provided in a set.

An improved one piece tibial tray uniquely characterized by its construction including an asymmetric keel extending from the bottom of the tibial tray base plate, whereby insertion of the tray during arthroplasty may be accomplished with a smaller than normal incision, enhancing the efficacy and safety of the surgical procedure. A fin on either or both sides of the asymmetric fin may be provided for enhanced stability of the tray.

Disclosed herein are methods and devices for securing soft tissue to a rigid material such as bone. A tissue anchoring device is described that comprises an anchor body and a spreader such that tissue may be captured or compressed between outside surfaces on the anchor and inside surfaces of a bone tunnel to secure the tissue within the tunnel. An anchoring device is described that comprises an anchor body having compressible tabs with teeth, and a spreader that forces the compressible tabs into an expanded state when inserted into anchor body, facilitating engagement between bone and the teeth of the compressible tabs. Also described is an inserter tool that can be used to insert the anchor into bone and move the spreader within the anchor to expand the anchor and capture the tissue between the anchor and the bone. Methods are described that enable use of the bone anchoring device to secure a tissue graft into the tibial and femoral bones during anterior cruciate ligament (“ACL”) reconstruction.

An improved tibial plateau leveling osteotomy plate is disclosed. The plate is contoured in its proximal head portion to more closely resemble the structure of the tibial bone segment that is cut and rotated during the procedure. The plate also preferably has screw holes in the proximal head portion that are machined through the pre-contoured proximal head portion and are designed to angle the screw in a targeted screw path with respect to the osteotomy.
