A partial resurfacing implant for use in repairing an articular cartilage defect site that includes a top articulating portion having a top surface that is configured with at least one radius of curvature to approximate the surface contour of the articular cartilage surrounding the defect site. The implant also includes a supporting plate that has a top surface and a bottom surface. The top surface is attached to the top articulating portion by a locking mechanism. The bottom surface of the supporting plate is constructed to facilitate the insertion of the implant into the defect site. Extending from the bottom surface of the supporting plate is at least one implant fixation portion. The at least one implant fixation portion is integrally connected to and is oriented about normal relative to the bottom surface. A method of repairing an articular cartilage defect with the partial joint resurfacing implant is also disclosed.
