Intended Use

The Vanguard™ Patella is intended use is for replacement of part of the knee joint in conjunction with a femoral and tibial component. Specifically: 1. Painful and disabled knee joint resulting from osteoarthritis, rheumatoid arthritis, traumatic arthritis where one or more compartments are involved. 2. Correction of varus, valqus or posttraumatic deformity. 3. Correction or revision of unsuccessful osteotomy, arthrodesis, or failure of previous joint replacement procedure.

Device Story

Vanguard™ Patella Components are orthopedic implants designed for knee joint replacement. Device features a true dome shape, under-surface grooves, and single or 3-peg fixation options; available with or without x-ray wire. Constructed from ArCom polyethylene. Used in conjunction with femoral and tibial components to restore joint function. Intended for surgical implantation in patients with degenerative or traumatic knee conditions. Device provides a bearing surface to replace damaged patellar cartilage, aiming to reduce pain and correct joint deformity. No software or electronic components.

Clinical Evidence

No clinical data provided. Equivalence established via engineering analysis.

Technological Characteristics

Material: ArCom polyethylene. Design: True dome shape, single or 3-peg configuration, optional x-ray wire. Mechanical fixation. No software or electronic components.

Indications for Use

Indicated for patients with painful/disabled knee joints due to osteoarthritis, rheumatoid arthritis, or traumatic arthritis; patients requiring correction of varus, valgus, or posttraumatic deformity; and patients requiring revision of unsuccessful osteotomy, arthrodesis, or failed previous joint replacement.

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).
