Femoral surface shaping guide for knee implants.

摘要

The present invention relates to a distal femoral surface shaping guide (10) for mounting on an intramedullary alignment guide (21) which references the central long axis of the femur in shaping the distal femoral surface and a method for shaping the distal femur using that shaping guide with particular applicability for shaping one condyle for attachment of a unicondylar prosthesis. The alignment guide of the present invention is adjustable relative to the surface of the condyle to insure that the distal femoral condyle (19) is resected relative to that surface. The alignment guide of the present invention utilizes visual sighting studs (82, 84) and provides a main body (12) which remains attached to the intramedullary alignment guide throughout the entire shaping of the distal femur.
