A patellar implant includes a body and at least one oblique anchoring pin. The body includes a bone-facing surface that is substantially planar and has a lateral end and a medial end. The body also includes an articulating surface opposite the bone-facing surface. The at least one oblique anchoring pin extends from the bone-facing surface at an acute angle toward the lateral end of the bone-facing surface. The at least one oblique anchoring pin includes a first end attached to the bone-facing surface and a second end spaced from the first end. A longitudinal axis extends from the first end to the second end. The longitudinal axis defines the acute angle with respect to the bone-facing surface. The at least one oblique anchoring pin extends into a surgically-prepared patella when the patellar implant is such that the surgically-prepared patella abuts the bone-facing surface.
