摘要:
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.

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.

A method for mounting an implant at an orthopedic joint includes forming a tunnel through a bone, the tunnel having an open second end on a natural or resected articulating surface of the bone and an open first end at a location on the bone spaced apart from the natural or resected articulating surface. A fastener is advanced into the tunnel from the first end of the tunnel. The fastener, which is at least partially disposed within the tunnel, is then secured to the implant which is disposed over the second end of the tunnel.
摘要:
A method includes resecting a portion of an articulation surface of a bone at a joint. A guide template is positioned on the resected articulation surface. The guide template at least partially bounds an opening that is disposed over the resected articulation surface. A portion of the resected articulation surface of the bone bounded within the opening of the guide template is then removed through the opening of the guide template.

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.
摘要:
A milling system for use in resecting at least a portion of a joint articulation surface of a bone includes an alignment guide having a top surface and an opposing bottom surface with an opening extending therebetween. Fasteners are used to secure the alignment guide to the bone so that the alignment guide is suspended above the bone. A template is removably mounted to the alignment guide so that a plurality of guide paths extending through template are aligned with the opening in the alignment guide. A mill extends down through the guide path and has a burr on the end thereof for resecting the bone.
摘要:
An implant for on a resected articulation surface of a bone includes a tray having a top surface and opposition surface. An opening extends completely through the tray between the top surface and the bone apposition surface. A bearing member is mounted on the top surface of the tray, the bearing member having a top articular surface. Anchor downwarly projects away from the bone apposition surface of the tray, the anchor being adapted to engage the bone and being configured so that the anchor can selective pass completely through the opening of the tray. A fastener connects the anchor to the tray.
摘要:
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.
