摘要：
A prosthetic patellar implant has a posterior articulation surface and an anterior attachment surface. The anterior attachment surface has a medial attachment surface and a lateral attachment surface. The medial and lateral attachment surfaces can be planar and angled relative to one another, meeting at a common intersection medially offset from the sagittal centerline of the implant. The medial and lateral attachment surfaces can include convexities. The anterior attachment surface can have one or more pegs and/or recesses.
