Optetrak LOGIC® Knee System

It is widely recognized that quality design and materials contribute to longevity and function when it comes to total joint implants. The design behind Optetrak began with a concept developed at the Hospital for Special Surgery in New York, one of the world’s leading orthopaedic research and treatment institutions. The patented design features and proprietary materials contribute to Optetrak’s overall longevity and excellent clinical performance, including 98 percent good to excellent results for up to 15 years.

SOME OF THE SYSTEM’S UNIQUE FEATURES INCLUDE:
• Wide range of shapes and sizes to meet your unique knee anatomy

• Innovative surgical approach to preserve and protect as much of your surrounding tissues, ligaments and natural bone as possible

• Net Compression Molded polyethylene inserts used to replicate your cartilage with optimized performance

• Curved shape of femoral and tibial components distributes weight and pressure more evenly across the area where the components meet

• Bone-sparing, high-flexion implant is designed to reduce strain on surrounding ligaments, while providing natural patella tracking and excellent range of motion

• Streamlined low profile instrumentation provides options for alternative surgical approaches, such as reduced incision size, which can potentially allow for quicker recovery.

DESIGN
Just like your natural knee, the components of a knee implant are subject to wear caused by bending, straightening and supporting weight. The shape of knee implant component - particularly the parts that slide against each other- is very important to ensure the least possible amount of wear.

One part of a knee system that is subject to wear is the place where the femoral and tibial components meet. When weight is placed unevenly, as often happens with normal activities of daily living, a high level of pressure may be exerted on the edge of the joint. This can lead to pain and discomfort.

The unique shape of Optetrak Logic’s femoral and tibial components distributes weight and pressure more evenly across the area where the components meet, even when weight is concentrated on one side of the knee.

Another key factor in the way a knee implant performs is the way the knee cap (patella) moves when you bend your knee. From the earliest knee designs, surgeons have struggled to recreate the correct patella tracking and limb alignment to ensure you have a comfortable, natural feel and function.

Optetrak knee systems feature a wide femoral groove that allows the patient’s kneecap to track naturally (to either the inside or the outside) during normal bending and straightening of the leg. This is different than some competitive designs, which force the knee cap to track along a specific path that can cause pain or stress on the surrounding ligaments and muscles.

MATERIALS

Another important element of a knee implant is the polyethylene or plastic that fits into the tibial tray and slides against the femoral component. Variations in the way the plastic is made, packaged, and sterilized can have a significant impact on the long-term viability of the plastic itself.

Exactech uses a clinically documented and successful manufacturing process, to ensure that you receive the highest quality plastic insert during your total knee replacement. It is documented that Exactech’s manufacturing process provides plastic inserts with some of the best resistance to overall wear compared to the others available from our industry.
