An orthopaedic implant system includes a trochlear, patellar, a uni-condylar implant component, and an anti-abrasion stud. The anti-abrasion stud has a head with a bearing surface, a bone-facing surface and a fixation post extending outward from the bone-facing surface of the head. The bearing surface of the stud is sized and shaped so that it can be implanted to supplement or extend the bearing surfaces of the other implant components to protect native articular cartilage from abrasion from the patellar component.
