Introduction to Total Knee Replacement

Total knee replacement, also known as total knee arthroplasty (TKA), is a highly successful surgical procedure aimed at alleviating pain from arthritis in the knee joint. Over half a million procedures are performed annually in the United States.

Exactech Knee System Overview

The Exactech knee system, with a history spanning over 30 years, originated at the Hospital for Special Surgery in New York. The Optetrak® lineage of knee systems is renowned for its excellent long-term clinical results, aiding patients worldwide in regaining mobility.

Procedure Details

The procedure involves replacing damaged portions of the femur, tibia, and patella with metal and/or plastic components to mimic natural knee movement. Depending on the severity of the condition, a surgeon may replace all or part of the knee.

Design and Material Considerations

The design of knee implants is crucial to minimize wear. The Optetrak Logic’s components are designed to distribute weight evenly, reducing pressure and discomfort. The system also features a wide femoral groove for natural patella tracking, unlike some competitive designs that may cause pain.

Proven Clinical Performance

Exactech emphasizes actual long-term clinical performance over laboratory projections. The Optetrak knees have documented a 98% success rate for up to 15 years, supported by a proven design and high-quality materials.

Unique Features of the Optetrak System

  • Wide range of solutions tailored to individual conditions.
  • Innovative surgical approaches to preserve natural tissues and bones.
  • Net Compression Molded polyethylene inserts for cartilage replication.
  • Curved femoral and tibial components for even weight distribution.
  • Bone-sparing, high-flexion implants for reduced ligament strain and natural patella tracking.
  • Streamlined instrumentation for alternative surgical approaches and potentially quicker recovery.

Material Quality

The quality of polyethylene used in the tibial tray is critical for long-term viability. Exactech’s manufacturing process ensures high resistance to wear, providing durable plastic inserts.

Conclusion

Exactech implants are designed to accommodate various anatomical and lifestyle factors, offering a proven design foundation enhanced by modern surgical technologies. The Optetrak systems provide confidence through their long-standing clinical success.

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...
