Persona Partial Knee System, Partial Tibia Cemented - Uncoated unicondylar knee tibia prosthesis, metallic

Intended purpose

Cemented Tibial Component is a part of the Persona Partial Knee System intended for patients with painful and/or disabling knee joints due to the following indications: Noninflammatory degenerative joint disease (NIDJD), e.g., osteoarthritis, avascular necrosis; traumatic arthritis; previous tibial condyle or plateau fractures with loss of anatomy or function; varus deformities; and revision of the articular surface of a previously implanted Persona Partial Knee System providing that the tibial plate locking mechanism is not compromised and the femoral and tibial plate components remain well fixed and undamaged. Also indicated for combined use with the Zimmer Gender Solutions Patello-Femoral Joint.

Functional description

PPK Tibia is a modular tibial baseplate made from Tivanium® Ti-6Al-4V Alloy. Proximal side is pocketed to receive the modular articular surface component. Stable cemented implant fixation is provided by three projections into tibial bone - two hourglass-shaped pegs and a triangular fin to resist implant movement relative to bone. The fin is fluted to provide additional cement interlock. Cemented use only.
