Intended Use

Resurfacing of the patella-femoral joint; cemented use.

Device Story

Prelude PF Resurfacing Knee System is a cemented patellofemoral arthroplasty implant. It consists of a distal femoral trochlear component and a patella component. The femoral component replaces the damaged trochlear groove surface; the patella component replaces the patellar articular surface. The device is implanted by a surgeon in an operating room setting. By restoring the articulating surfaces of the knee, the system aims to alleviate pain and restore normal knee function. The femoral component is available in multiple sizes and is manufactured from CoCrMo with a porous titanium coating. The patella component is available in single or three-peg configurations made of UHMWPE with a stainless steel x-ray wire.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on non-clinical performance testing and engineering rationales.

Technological Characteristics

Femoral component: CoCrMo (ASTM F-75 cast or ASTM F-2886 MIM) with porous titanium coating. Patella component: UHMWPE (ASTM F-648) with stainless steel x-ray wire. Cemented fixation. Femoral component available in 9 sizes; patella component available in 25mm, 28mm, and 31mm diameters with 6.2mm or 8mm thicknesses, in single or three-peg options.

Indications for Use

Indicated for cemented patellofemoral arthroplasty in patients with degenerative arthritis in the distal femur and patella, history of patellar dislocation or fracture, or failed previous surgery (arthroscopy, tibial tubercle elevation, lateral release) with persistent pain, deformity, or dysfunction.

Regulatory Classification

Identification

A knee joint patellofemoral polymer/metal semi-constrained cemented prosthesis is a two-part device intended to be implanted to replace part of a knee joint in the treatment of primary patellofemoral arthritis or chondromalacia. 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 a component made of alloys, such as cobalt-chromium-molybdenum or austenitic steel, for resurfacing the intercondylar groove (femoral sulcus) on the anterior aspect of the distal femur, and a patellar component made of ultra-high molecular weight polyethylene. This generic type of device is limited to those devices intended for use with bone cement (§ 888.3027). The patellar component is designed to be implanted only with its femoral component.

#### Summary of the technological characteristics of the device compared to the predicate

The Prelude PF Resurfacing Knee System femoral components are comprised of CoCrMo and will be available for cemented application for fixation to the prepared femoral. The femoral component is to replace the damaged portion of the focal defect in the trochlear groove of the femur in the patient and restore normal knee function similar to the movement of a natural knee. The predicate device femoral components are also comprised of CoCrMo for cemented application and are similar to the Prelude PF femoral components in design and dimension.

The Prelude PF Resurfacing Knee System patella components are comprised of polyethylene (UHMWPE) and intended for cemented application available in either single or three-peg options for fixation. These patella components are identical to the Vanquard Series A patella components (K040770) and similar to the patellofemoral predicate patella component designs.

A tabular summary of the technological characteristics is provided below.
