Surgical Technique
This section outlines the step-by-step approach for the Triathlon Knee System, focusing on tibial preparation, femoral resection, and joint line establishment to ensure proper alignment and stability.
3.1 Tibial Platform Preparation
Tibial platform preparation is critical for ensuring proper implant fit and alignment. The process begins with creating the tibial platform, using trial augments to achieve optimal positioning. The trial tibial baseplate is inserted, and the joint line is established by referencing the medial epicondyle. The extension gap is filled with the appropriate trial insert, ensuring stability and proper patellofemoral tracking. Pinning the components through the slot ensures secure placement during the procedure. This step-by-step approach ensures accurate alignment and a stable foundation for the femoral and tibial components, facilitating natural knee motion and long-term durability of the implant.
3.2 Femoral Preparation and Resection
Femoral preparation and resection involve precise steps to ensure proper sizing and alignment. The femoral alignment guide is used to determine the correct positioning, and the distal resection guide helps achieve accurate bone cuts. The process includes advancing the rod and guide slowly up the intramedullary canal to the desired depth. Once the femoral component is sized, the appropriate cutting guides are attached to the distal and posterior aspects of the femur. Resection is performed to match the implant geometry, ensuring proper ligament balance and patellofemoral tracking. This step is crucial for achieving a stable, natural-feeling knee joint post-surgery.
3.3 Joint Line Establishment and Extension Gap Management
Joint line establishment is critical for achieving a natural knee function. The medial epicondyle is often used as a reference point to set the joint line accurately. Extension gap management involves filling the gap with an appropriate trial insert and pinning it through a designated slot to ensure stability. Proper joint line positioning and gap balancing are essential for maintaining ligament tension and ensuring optimal knee kinematics. This step ensures that the knee functions naturally, with proper flexion and extension, and minimizes the risk of instability or restricted range of motion post-surgery.
