An implant system, comprising:
- a cannulated post comprising a threaded portion configured to engage bone beneath a patient's articular surface;
- an implant having a perimeter defining an outer bound of a continuous load bearing surface that substantially matches at least one curvature of said patient's articular surface;
- a fixation element configured to couple said post to said implant, wherein said fixation element is further configured to permit said implant to rotate with respect to said post;
- and
- a guide pin configured to engage said bone and provide an axis in said bone, wherein at least a portion of said guide pin is configured to be received only in said cannulated post of said implant.
