The Persona Knee System utilizes a modular design between the tibial plates and articular surfaces. This device is indicated for patients with severe knee pain and disability due to: - Rheumatoid arthritis, osteoarthritis, traumatic arthritis, । polyarthritis. - Collagen disorders, and/or avascular necrosis of the ເ · femoral condyle. - Post-traumatic loss of joint configuration, particularly when there is patellofemoral erosion, dysfunction or prior patellectomy. - Moderate valgus, varus, or flexion deformities. — - The salvage of previously failed surgical attempts or for l a knee in which satisfactory stability in flexion cannot be obtained at the time of surgery. Porous coated tibial baseplate components may be used cemented or uncemented (biological fixation). All other femoral, tibial baseplates and all-polyethylene (UHMWPE and VEXLPE) patella components are indicated for cemented use only. The proposed Zimmer® Persona™ Personalized Knee System components are similar or identical in intended use, materials, sterility, and performance characteristics to the predicate devices. Clinical Performance and Conclusions: Clinical data and conclusions were not needed for this device. Non-Clinical Performance and Conclusions: Vivacit-E material characteristics for the Persona Knee System are identical to the predicate Zimmer Vivacit-E Acetabular Polyethylene Liners (K120370). In contrast to conventional polyethylene, the Vivacit-E material is delamination resistant and exhibits a reduction in wear according to knee simulator bench testing. # Comparison to Predicate Device: Performance Data (Nonclinical and/or Clinical): {2}------------------------------------------------ Bench testing outlined below was conducted according to FDA guidance documents: | Property or<br>Characteristic | Test Results | |--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Cantilever Fatigue Test of the<br>Persona Trabecular Metal Tibia | Demonstrated adequate fatigue strength in the cantilever<br>loading condition. | | Wear Testing of Persona CR<br>Vivacit-E UHMWPE Articular<br>Surfaces Under Load and Motion<br>Curves From the ISO 14243<br>Standard | Demonstrated that the wear characteristics of the Persona<br>CR articular surfaces, when articulated against the Persona<br>CR femoral component, are sufficient to survive expected in<br>vivo loading conditions. | | Wear Testing of Persona PS Vivacit-<br>E UHMWPE Articular Surfaces<br>Under Load and Motion Curves<br>from the ISO 14243 Standard | Demonstrated that the wear characteristics of the Persona PS<br>and UC articular surfaces, when articulated against a<br>Persona femoral component, are sufficient to survive<br>expected in vivo loading conditions. | | Spine Fatigue Evaluation of the<br>Persona PS Vivacit-E Articular<br>Surfaces | Demonstrated that the spine of the Persona PS Vivacit-E<br>articular surfaces has sufficient strength to survive expected<br>in vivo stress/strain loading conditions. | | Tibiofemoral Constraint Evaluation<br>of the Persona CR/PS/UC Vivacit-E<br>UHMWPE Articular Surface | Demonstrated that constraint values for the Persona Vivacit-<br>E articular surfaces are comparable to data from the Persona<br>Conventional UHMWPE articular surfaces. Therefore, the<br>Persona Vivacit-E articular surfaces provide adequate<br>constraint through the needed tibiofemoral flexion angles. | | Persona Vivacit-E Patella Contact<br>Area, Contact Pressure, and<br>Constraint Evaluation | Evaluated material properties of Vivacit-E and demonstrated<br>that when mated with a Persona femoral component, it has<br>sufficient mechanical strength to survive expected in-vivo<br>loading conditions and provide adequate constraint. | | Tibiofemoral Contact Area and<br>Contact Pressure Evaluation of the<br>Persona CR/UC/PS Vivacit-E<br>UHMWPE Articular Surfaces | Demonstrated that the contact area and contact pressure of<br>the Persona Vivacit-E articular surfaces are comparable to<br>data from previous testing on Persona Conventional<br>UHMWPE articular surfaces. | | Property or<br>Characteristic | Test Results | | Anterior Liftoff Testing of the<br>Persona Vivacit-E Articular<br>Surfaces | Demonstrated sufficient locking mechanism strength to<br>survive potential worst case anterior liftoff loading<br>conditions during deep flexion. | | Posterior Liftoff Fatigue Strength of<br>the Persona Vivacit-E Articular<br>Surfaces | Demonstrated sufficient locking mechanism strength to<br>survive potential worst case shear loading conditions. | | Static Shear Strength of the Persona<br>Tibia Locking Mechanism | Demonstrated adequate resistance of the modular articular<br>surfaces to disassembly. | | Modified Metallic Surface<br>Characterization for the Persona<br>Porous Two Peg Tibia Component<br>with Trabecular Metal | Evaluated the Trabecular Metal material according to<br>applicable mechanical, physical and chemical analyses listed<br>in the guidance document. | | Static Tensile, Static Shear and<br>Shear Fatigue of Trabecular Metal<br>Diffusion Bonded to Tivanium -<br>One Hour Cycles | Demonstrated that one hour diffusion bonding cycles<br>produces a bond that meets the 20 MPa static tensile test<br>requirement. | | Evaluation of Interactions of the<br>Zimmer Legacy Knee and Persona<br>Primary Implant Systems with the<br>Magnetic Fields in the Magnetic<br>Resonance Imaging (MRI)<br>Environment | Demonstrated safety and compatibility within the MRI<br>environment. | {3}------------------------------------------------ . {4}------------------------------------------------ #### DEPARTMENT OF HEALTH & HUMAN SERVICES Public Health Service Food and Drug Administration 10903 New Hampshire Avenue Document Control Center - WO66-G609 Silver Spring, MD 20993-002 NOV 7 2012 Zimmer.
