• Attributes: Therapeutic

Intended Use

Non-cemented total knee replacement

Device Story

Metallic knee femoral and tibial base-plate components designed for non-cemented (porous coated) application. Components are identical to previously cleared cemented versions. Used in total knee replacement surgery to address joint pain, disability, or deformity. Intended for use with previously cleared tibial bearings, all-polyethylene patellar components, and non-porous coated femoral/tibial base-plates. Operates as a mechanical implant to restore joint function.

Clinical Evidence

No clinical data provided.

Technological Characteristics

Metallic femoral and tibial base-plate components with porous coating for uncemented fixation. Identical in design and material to previously cleared cemented components.

Indications for Use

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