Intended Use

The indications for the Regenerex™ Tibial Components include: - Painful and disabled knee joint resulting from osteoarthritis, rheumatoid arthritis, 1. traumatic arthritis where one or more compartments are involved. - 2. Correction of varus, valgus or posttraumatic deformity. - 3. Correction or revision of unsuccessful osteotomy, arthrodesis, or failure of previous joint replacement procedure. These devices are single-use implants intended for cemented or uncemented applications.

Device Story

Regenerex™ Tibial Components are single-use orthopedic implants for primary knee arthroplasty. Designed to integrate with existing Biomet tibial tray profiles and sizing systems; used in cemented or uncemented applications. Implants replace damaged joint surfaces to address pain and deformity resulting from arthritis or previous surgical failure. Operated by orthopedic surgeons in clinical/hospital settings. Device provides structural support for knee joint; restores joint function; improves patient mobility.

Clinical Evidence

No clinical data provided as a basis for substantial equivalence. Bench testing only.

Technological Characteristics

Porous-coated metal/polymer knee prosthesis. Design and sizing are similar or identical to predicate Biomet tibial components. Intended for cemented or uncemented fixation.

Indications for Use

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

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.
