Abstract: A milling system for use in resecting at least a portion of a joint articulation surface of a bone includes a template having a base with a top surface, an opposing bottom surface, and an opening extending therebetween. One or more fasteners are used to removably mount the template on a bone. A guide is movably mounted on the template and projecting across at least a portion of the opening of the template. The guide is selectively movable across at least a portion of the opening of the template. A rotatable mill is mounted on the guide. The mill is selectively movable along at least a portion of the length of the guide.

Abstract: A prosthesis for the replacement of multiple diseased or traumatized spinal facets comprises a portion that replaces at least a bony portion of the facets to be replaced and where the prosthesis attaches to the vertebra in a manner that does not require attachment to, or abutment against, the lamina. Multiple configurations of the prosthesis provide for replacement of the two inferior facets, the two superior facets, a superior and inferior facet, or all four facets. A method of installing the prosthesis is provided that is comprised of the steps of resecting at least a portion of the facets that carry the diseased or traumatized spinal facets and attaching the prosthesis in a manner that does not require attachment or abutment against the lamina.

Abstract: Apparatus and method for reconstructing a ligament.

Abstract: A method of performing a tibial tubercle osteotomy includes cutting a bone portion of a tibial tubercle from a remaining portion of the tibial tubercle, at least a portion of a patella ligament being attached to the bone portion. The bone portion of the tibial tubercle is separated from the remaining portion of the tibial tubercle such that the patella ligament remains attached to the bone portion. After completing a surgical procedure, the separated bone portion of the tibial tubercle is reattached to the remaining portion of the tibial tubercle.

Abstract: A method of cutting bone with a bone die cutter includes positioning complementary cutting dies on at least substantially opposing sides of a bone. At least one of the cutting dies is pressed toward the other so that the cutting dies cut a bone portion from the bone. The cut bone portion is separated from the remainder of the bone. The cut bone portion is subsequently reattached to the bone at the location from which it was removed.

Abstract: A guide template for use in resurfacing a portion of a bone includes a body adapted for positioning over a natural or resected articulation surface of the bone. The body has a top surface and an opposing bottom surface that each extend between a proximal end and an opposing distal end. The body at least partially bounds an opening extending between the top surface and the bottom surface. At least a portion of the top surface or the bottom surface has a convex curvature or a concave curvature that extends between the proximal end and the opposing distal end. At least three spaced apart supports project below the bottom surface of the body such that the body can be supported by the supports. Fasteners are provided for securing the body to the bone.

Abstract: A trochlear groove implant includes a body having a first side with an articular surface and an opposing second sid with a bone apposition surface, the articular surface and the bone apposition surface each extending between a proximal end and an opposing distal end of the body. An elongated channel is recessed on the articular surface and longitudinally extends between the opposing ends of the body. An elongated ridge outwardly projects from the bone apposition surface and longitudinally extends between the opposing ends of the body.

Abstract: An implant for resurfacing at least a portion of an articulation surface of a bone includes a body having a first side with a top articular surface and an opposing second side with a bone apposition surface. The bone apposition surface is adapted to bias against a natural or resected articulation surface of a bone. An elongated flexible first line is coupled to and extends from the body.

Abstract: The present invention relates to guide systems and methods for resecting at least a portion of a joint articulation surface on a bone by mounting a first cutting guide on the joint articulation surface. A first portion of the joint articulation surface is resected using the first cutting guide as a guide for resecting. A second cutting guide is then mounted on the joint articulation surface following which the first cutting guide is removed. A second portion of the joint articulation surface is then resected using the second cutting guide template as a guide for resecting, at least a section of the second portion of the joint articulation surface having been previously covered by the first guide template.

Abstract: A method includes the acts of sliding a first end of a flexible first line through a channel in a first bone anchor. A portion of the first line is connected to an implant having a top articular surface and an opposing bone apposition surface. The first line extending between the implant and the first bone anchor is then tensioned. While the tensioning force is maintained on the first line, the first line is secured to the first bone anchor.

Abstract: A prosthesis for the replacement of a diseased or traumatized facet of a mammalian vertebra includes a surface that articulates with another prosthetic facet or a natural facet, a portion that replaces at least a bony portion of the diseased or traumatized spine facet which is to be replaced, and an element to attach the prosthesis to the vertebra in a manner that does not require attachment to or abutment against the posterior arch. A method of installing the prosthesis includes the steps of resecting at least a portion of a facet and attaching the prosthesis in a manner that does not require attachment or abutment against the posterior arch.
