Intended Use

The OPTETRAK Comprehensive Knee Systems are indicated for use in skeletally mature individuals undergoing primary surgery for total knee replacement due to osteoarthritis, osteonecrosis, rheumatoid arthritis and/or post-traumatic degenerative problems. They are also indicated for revision of failed previous reconstructions where sufficient bone stock and soft tissue integrity are present. In the USA, the OPTETRAK Comprehensive Knee System is indicated for cemented use only.

Device Story

The Optetrak Logic Porous Femoral Component is a modification of existing femoral components for total knee arthroplasty. The device consists of a cobalt-chrome femoral component with an added beaded, sintered porous coating on non-articulating surfaces to facilitate bone apposition. It is intended for use by orthopedic surgeons in clinical settings. The device is implanted during total knee replacement surgery to restore joint function. The porous coating design is based on previously cleared Exactech porous-coated components. The device is used in conjunction with cemented fixation as per US indications. Clinical benefit is derived from the mechanical replacement of the knee joint in patients with degenerative conditions.

Clinical Evidence

No clinical data provided. Evidence consists of bench testing: porosity/pore size/thickness (ASTM F1854-09), shear strength (ASTM F1044-05), tensile strength (ASTM F1147-05), shear fatigue (ASTM F1160-05), and abrasion resistance (ASTM F1978-12). All mechanical testing met or exceeded minimum requirements. A cadaver lab evaluation confirmed the prototype could be implanted without difficulty.

Technological Characteristics

Cobalt-chrome femoral component with sintered beaded porous coating. Porosity: 65.8%; mean pore size: 339.9 μm; coating thickness: 766.9 μm. Testing performed per ASTM F1854-09, F1044-05, F1147-05, F1160-05, and F1978-12. Device is a semi-constrained cemented prosthesis.

Indications for Use

Indicated for skeletally mature individuals undergoing primary total knee replacement or revision of failed reconstructions due to osteoarthritis, osteonecrosis, rheumatoid arthritis, or post-traumatic degenerative problems, provided sufficient bone stock and soft tissue integrity exist.

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).

# Exactech® Optetrak Logic® Porous Femoral Component Traditional 510(k) - 510(k) Summary of Safety and Effectiveness

## Device Description:

The proposed Optetrak Logic Porous Femoral Component devices represent modifications to existing Optetrak Logic Total Knee System (K093360) and Optetrak Logic CR Knee System femoral components (K111400 and K121307) used in total knee arthroplasty. The only difference between proposed Optetrak Logic Porous Femoral Components and predicate Optetrak Logic femoral components is the addition of a beaded, sintered cobalt-chrome coating to specific non-articulating areas of the subject devices, similar to the coating added to predicate Optetrak Porous Coated Cruciate Retaining Femoral Component devices cleared per 510(k) K935726 and predicate Exactech Posterior Stabilized Porous Femoral Component devices cleared per 510(k) K935773.

Both predicate and proposed devices share the following similarities:

- the same indications for use .
- . the same materials
- . the same basic fundamental scientific technology
- . the same device compatibility
- the same materials and processes used for packaging and sterilization .
