Intended Use

When a mechanical alignment approach is utilized, 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 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 a knee in which satisfactory stability in flexion cannot be obtained at the time of surgery. When a kinematic alignment approach is utilized, 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 femoral condyle. - Moderate valgus, varus, or flexion deformities. The kinematic alignment (KA) surgical technique may only be used with Persona CR femoral components, Persona CR or UC articular surface components, and cemented nonporous Persona tibial components without a stem extension. Porous coated components may be used cemented (biological fixation). All other femoral, tibial baseplate, and all-polyethylene (UHMWPE and VEHXPE) patella components are indicated for cemented use only.

Device Story

Persona Personalized Knee System is a modular, semi-constrained knee prosthesis for total knee arthroplasty. Subject modification adds Ti-Nidium (nitrided titanium alloy) cruciate retaining (CR) femoral components to existing system. Device resurfaces femoral, tibial, and patellar articulating surfaces. Components available in multiple sizes to accommodate patient anatomy. Used in OR by orthopedic surgeons. Femoral components articulate against tibial and patellar surfaces to restore joint function and stability. Benefits include pain relief and improved mobility for patients with severe knee joint degeneration. Provided sterile and single-use.

Clinical Evidence

No clinical data was deemed necessary for the subject device. Substantial equivalence is supported by non-clinical bench testing, including intercondylar notch deformation, posterior condyle fatigue, wear testing of UHMWPE articular surfaces against Ti-Nidium components per ISO 14243-3, 3rd body particle wear assessment, MRI environment evaluation, and bacterial endotoxin testing per ANSI/AAMI ST 72:2011.

Technological Characteristics

Modular knee prosthesis. Femoral components: Titanium alloy (ASTM F136) with Ti-Nidium nitriding surface hardening. Articular surfaces: UHMWPE and VEHXPE. Semi-constrained design. Sterilized, single-use. No software or electronic components.

Indications for Use

Indicated for patients with severe knee pain and disability due to rheumatoid arthritis, osteoarthritis, traumatic arthritis, polyarthritis, collagen disorders, avascular necrosis of the femoral condyle, post-traumatic joint loss, or moderate valgus/varus/flexion deformities. Includes salvage of failed surgeries.

Regulatory Classification

Identification

A knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a knee joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a tibial component or components and a retropatellar resurfacing component made of ultra-high molecular weight polyethylene. This generic type of device is limited to those prostheses intended for use with bone cement (§ 888.3027).

## Purpose and Device Description:

The purpose of this submission is for the addition of the Ti-Nidium cruciate retaining (CR) femoral components to the Persona Personalized Knee System. These modifications do not change the intended use or fundamental scientific technology of the device.

The Persona Personalized Knee System is a semiconstrained modular knee prosthesis designed to resurface the articulating surface of the femoral, tibial and patellar bones. With this submission, femoral components made from Titanium alloy (ASTM F136) that undergo the Ti-Nidium nitriding surface hardening treatment are being added to the system. These femoral components articulate against tibial and patellar articular surfaces to form a total knee system. This design is available in multiple sizing options to accommodate a wide range of anatomies. "Narrow" femoral components have a smaller M/L dimension than the "Standard" femoral components. This femoral component, when used with a CR or Medial Congruent (MC) articular surface, can accommodate a maximum active flexion of 155°, and with an Ultra Congruent (UC) articular surface, can accommodate a maximum active flexion of 145°. These femoral components are provided sterile and single use.

## Intended Use and Indications for Use:

When a mechanical alignment approach is utilized, this device is indicated for patients with severe knee pain and disabilitv due to:

- Rheumatoid arthritis, osteoarthritis, traumatic arthritis, polyarthritis.

- Collagen disorders, and/or avascular necrosis of the 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 a knee in which satisfactory stability in flexion cannot be obtained at the time of surgery.

{5}------------------------------------------------

When a kinematic alignment approach is utilized, this device is indicated for patients with severe knee pain and disability due to:

- Rheumatoid arthritis, osteoarthritis, traumatic arthritis, polvarthritis.

- Collagen disorders, and/or avascular necrosis of the femoral condyle.

- Moderate valgus, varus, or flexion deformities.

The kinematic alignment (KA) surgical technique may only be used with Persona CR femoral components. Persona CR or UC articular surface components, and cemented nonporous Persona tibial components without a stem extension.

Porous coated components may be used cemented or uncemented (biological fixation). All other femoral, tibial baseplate, and all-polyethylene (UHMWPE and VEHXPE) patella components are indicated for cemented use only.
