  • Rotary Arc Patella Articulating Geometry
    Publication number: 20210085473
    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.
    Type: Application
