Persona Partial Knee System, Vivacit-E® Highly Crosslinked Polyethylene Partial Articular Surface - Unicondylar knee insert

Intended purpose

Vivacit-E® Partial Articular Surface 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 Articular Surface is a modular component made from Vivacit-E® Vitamin E HXPE. Locking mechanism of baseplate permits articular surface to be inserted into the baseplate intraoperatively and also to be removed and exchanged after the baseplate has been implanted. Top of articulating surface has a gentle radius in the sagittal plane to improve stress distribution. This unconstrained design helps prevent kinematic conflict between resurfaced condyle and the healthy condyle. Uncemented use only.
