Zimmer Biomet Cementless Partial Knee OK’d

FDA has approved a Zimmer Biomet PMA supplement for its Oxford Cementless Partial Knee. The company says the device allows partial knee replacement procedures with “improved fixation, better long-term implant survival rate and improved efficiency in the operating room compared to the Oxford Cemented Partial Knee procedure.”

Unlike traditional partial knee replacements that use bone cement to secure the device in place, a cementless approach allows for natural bone growth to secure the implant for better long-term fixation, Zimmer Biomet says. The device also features a mobile bearing that can move with the femoral component throughout the entire range of motion to mimic natural knee movement, it says, adding that the design provides better range of motion, a more natural feel and a more stable implant-to-bone fixation. Additionally, its tibial and femoral components have a titanium and hydroxyapatite coating to promote bone growth into the implant.
