Intended Use

The Persona™ Personalized Knee System is a semiconstrained modular knee prosthesis designed to resurface the articulating surface of the femoral, tibial and patellar bones. The Persona Knee System utilizes a modular design between the tibial plates and articular surfaces. The addition of the Trabecular Metal™ femoral component will provide surgeons with the ability to implant with, or without cement (biological fixation). 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. Porous coated components may be used cemented or uncemented (biological fixation). All other femoral, tibial baseplate, and all-polyethylene (UHMWPE and VEXLPE) patella components are indicated for cemented use only.

Device Story

The Persona™ Personalized Knee System is a modular, semiconstrained knee prosthesis designed to resurface femoral, tibial, and patellar articulating surfaces. It incorporates a Trabecular Metal™ femoral component, allowing for either cemented or uncemented (biological fixation) implantation. The system is intended for use by orthopedic surgeons in clinical settings to address severe knee pain and disability resulting from arthritis, necrosis, or previous surgical failure. By restoring joint configuration and stability, the device aims to improve patient mobility and reduce pain. The system is used during total knee arthroplasty procedures; surgeons select appropriate modular components to match patient anatomy. The device is compatible with MRI environments.

Clinical Evidence

No clinical data was required or provided for this device. Substantial equivalence was established through non-clinical bench testing, including posterior condyle fatigue testing and mechanical/chemical characterization of the Trabecular Metal™ porous surface.

Technological Characteristics

Modular knee prosthesis featuring Trabecular Metal™ porous-coated femoral components. Materials include UHMWPE and VEXLPE for patella components. Designed for cemented or uncemented (biological fixation) use. Testing conducted per FDA guidance for knee joint metal/polymer porous-coated uncemented prostheses and modified metallic surfaces. MRI compatible.

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. Also indicated for salvage of failed surgical attempts or knees lacking stability in flexion.

Regulatory Classification

Identification

A knee joint patellofemorotibial metal/polymer porous-coated uncemented 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 is designed to achieve biological fixation to bone without the use of bone cement. This identification includes fixed-bearing knee prostheses where the ultra high molecular weight polyethylene tibial bearing is rigidly secured to the metal tibial base plate.

Special Controls

*Classification.* Class II (special controls). The special control is FDA's guidance: “Class II Special Controls Guidance Document: Knee Joint Patellofemorotibial and Femorotibial Metal/Polymer Porous-Coated Uncemented Prostheses; Guidance for Industry and FDA.” See § 888.1 for the availability of this guidance.
