Intended Use

The Trabecular Metal Femoral Cone Augments are indicated for use in the reconstruction of bony defects in knee reconstruction due to severe degeneration, trauma, or other pathology of the knee joint, and in the revision or salvage of failed, previously reconstructed knee procedures and implants. The Trabecular Metal Femoral Cone Augments are for cemented use only in the USA, and for cementless or cemented use outside the USA.

Device Story

Trabecular Metal Femoral Cone Augments; rectangular, tapered, hollow-center design; used to fill femoral cavitary defects during knee arthroplasty. Augments interface with Zimmer LCCK or Rotating Hinge Knee femoral components; fixed to femoral component via bone cement. Hollow center allows passage of femoral stem into canal. Used by orthopedic surgeons in clinical settings. Provides structural support for implants in compromised bone; facilitates reconstruction in revision or salvage cases.

Clinical Evidence

No clinical data provided. Substantial equivalence determined via comparison of technological characteristics and reliance on previous testing of Trabecular Metal material.

Technological Characteristics

Trabecular Metal material; rectangular, tapered, hollow-center geometry; cemented fixation (USA); compatible with LCCK and Rotating Hinge Knee femoral components.

Indications for Use

Indicated for patients requiring knee reconstruction due to severe degeneration, trauma, or other knee joint pathology, including revision or salvage of failed prior knee procedures/implants.

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).

The Trabecular Metal Femoral Cone Augments are to be used Device in conjunction with Zimmer Inc.'s LCCK and Rotating Hinge ൗescription: Knee femoral components. The subject devices are used to Rhos remoral cavitary defects encountered when implanting either of these two systems. The design of the augment interface inversely corresponds to the design of an LCCK or Rotating Hinge Knee femoral component. The augment has a rectangular, tapered shape. The opposing sides of the rectangle are longer than the center allowing the sides of the augment to fit into the condyles of the femoral component the dugment to fit the augment to fit over the "box" of the femoral The center of the augment is hollow to allow component. passage of the stem through the center of the cone and into the femoral canal. The augments are fixed to the femoral component with bone cement. The Trabecular Metal Femoral Cone Augments are for cemented use along the bone in the USA, and for cementless or cemented use along the bone outside the USA.
