Persona Partial Knee System, Partial Femur Cemented - Uncoated unicondylar knee femur prosthesis

Intended purpose

Cemented Femoral 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 Femur contains 2 fluted posts angled 30° from the sagittal anatomic axis of the femur to resist component loosening in extension and flexion. Wide contour of frontal plane provides bone coverage and minimises stress concentration in bone & cement. Tip of distal condyle provides native patella with impingement-free knee flexion. Posterior femoral condyle is curved to accommodate knee flexion without compromising articular contact area. Made of Zimaloy CoCrMo alloy. Cemented use only.
