Abstract: A method of using a guide system for resecting a bone through incisions of the type utilized for arthroscopic procedures is provided. The guide system comprises a first alignment pin, a second alignment pin and a wire saw. The first alignment pin is configured to be inserted through a first incision into a bone in a first orientation. The second alignment pin is configured to inserted through a second incision into the bone in a second orientation. The first alignment pin and the second alignment pin are configured and oriented to define a resection plane of reference through which the bone is to be resected and the wire saw is configured to be inserted through the first and second incisions to be guided by the first and second alignment pins while being moved to resect the bone.

Abstract: Patient specific surgical instruments, and in particular cutting guides, and methods of use and manufacture are described. The surgical instrument can be used in an orthopaedic arthroplasty procedure to be carried out on a joint of a patient and can allowing soft tissue balancing for the joint. The instrument comprises a body having an attachment area configured using data specific to a bone of the joint of the patient so as to attach to the bone in a unique position. The instrument includes at least a first cutting guide and an adjustment mechanism operable to change the position of the cutting guide relative to the bone.

Abstract: A kit for a prosthesis system includes a plurality of first components, each of the plurality of first components for replacing one of a plurality of first surface portions of a bone, a second component for replacing a second surface portion of the bone and a resilient connector for connecting at least one of the plurality of first components to the second component. In accordance with one method, components from a prosthesis system kit used to replace adjacent portions of a bone surface are assembled ex vivo.

Abstract: An improved sliding patellar replacement component is provided. Various combinations of translational and/or rotational degrees of freedom are provided by boss and channel configurations between the base subcomponent of the replacement component and the articulating subcomponent of the patellar replacement component. In one embodiment, spin about one axis is restricted by a spin stop that may be movable to allow for ease of assembly. Alternatively, the boss and channel are configured to function as a spin stop. Assembly of the patellar replacement component in one embodiment is simplified by the provision of a boss assembly region.

Abstract: A prosthesis system includes a first component having an outer surface, an inner surface, a first side and a second side, the first component configured to replace a first portion of a surface of a bone. A second component is configured to replace a second portion of the surface of the bone and a spacer is configured to be located adjacent to the first side of the first component and between the first component and the second component when the first component and the second component replace the first portion and second portion, respectively, of the surface of the bone.
