Abstract: Disclosed herein are patellar implants and methods to prepare bone for receiving the same. The patellar implant may include an articulating surface with an elliptically shaped median ridge. The anterior surface of the patellar implant may have a non-planar surface to engage with a resected natural patella. The non-planar surface may allow for varying thickness of the patellar implant. The patellar implant may include dual attachment features to secure patellar implant to a resected patella by onlay and inlay techniques. A method for attaching a patellar implant to a patella may include onlay and inlay techniques and may further include bone preparation at the implant-bone interface.

Abstract: A surgical guide system includes a shell trial having a convex side configured to engage an acetabulum, a concave side forming a cavity therein, and windows extending through the convex and concave sides for viewing bone. The system further includes a liner trial having a convex side configured to be received within the cavity of the concave side of the shell trial, and a concave side with recessed hole guides there, wherein more than one of the hole guides align with the windows of the shell trial when the liner trial is received therein. The system further includes an acetabular cup implant having a convex side configured to engage an acetabulum, a concave side, and a thickness extending between the concave and convex sides, the concave side defining a cavity configured to receive the liner trial.
