The Triathlon Partial Knee Resurfacing (PKR) System was designed to make unicompartmental knee resurfacing (UKR) potentially easier and more straight forward. The patented single radius design, coupled with the ability to balance the flexion and extension gaps, is intended to produce more stable, natural knee motion. The result is an elegant solution, helping to restore normal physiologic ligament tension and knee kinematics throughout the range of motion.

Features & Benefits：

Motion

• Patented Single Radius – designed to provide ligament stability through the range of motion.3,4
• Ligament Balancing – designed to restore normal physiological ligament tension.
• Anatomic Shape – the femoral component features a 7.5° bend to match the natural curve of the femoral condyle.

Simplicity

• Easy Size Interchangeability – bone cuts are the same for all 6 sizes. This provides intra-operative flexibility to change sizes without recutting the femur.
• Straightforward Gap Balancing Technique – instruments designed to provide a simple way to balance flexion and extension gaps and restore normal ligament tension.
• Procedural Efficiency – fewer instruments, pinless option, and “drill through” trials, allow surgeons to optimize positioning of the femoral component prior to peg prep.
• Navigation – designed for use with navigation software.

Confidence

• X3 Advanced Bearing Technology –Triathlon Partial Knee Resurfacing system utilizes Stryker’s proprietary X3 highly crosslinked bearing technology, which has shown a 96% decrease in wear in laboratory testing compared to competitive premium bearing surfaces in TKR’s.
• Forgiving Design – the femoral component can withstand up to +/- 10 degrees of malalignment without edge loading.
