Introduction
The Stryker Triathlon Knee System is a primary total knee replacement system designed to work with the body. With over 15 years and over 3 million implantations worldwide‚ Triathlon has a long clinical history. In a 10-year follow-up study‚ Triathlon showed 99 survivorship. Triathlon was designed to incorporate some of the most studied features of Stryker’s prior designs that have been shown to address many of the main reasons for revision TKA‚ such as instability‚ patellofemoral tracking complications and loosening/osteolysis. The Triathlon knee system offers surgeons a variety of options depending on disease‚ deformity and patient demand including cruciateretaining‚ condylar-stabilizing‚ posterior-stabilizing and difficult primary options. Studies have shown that Triathlon and the single radius provide⁚
Stability⁚ Triathlon’s single radius design allows for mid-flexion stability. A single vs. multi-radius functional outcome study concluded that Triathlon’s advantages in stability‚ walking‚ stair climbing and knee straightening stem from the single radius design‚ particularly its longer moment arm and enhanced ligament stability based on maintained isometry throughout knee range of motion. A fluoroscopic study on Triathlon patients showed the femoral component was kinematically stabilized in mid-flexion ranges. Additionally‚ gait reviews comparing patients with a single or multi-radius knee implant showed that patients with a single radius knee implant experienced gait patterns that more closely mimicked that of the non-diseased control group.
Satisfaction⁚ A review of Triathlon patients showed a high level of satisfaction at seven year follow up. Survivorship⁚ Multiple studies and joint registries from around the world consistently show a high rate of survivorship with Triathlon with more than 10 years of follow up. The Triathlon Total Knee System is available for use with the Mako System for Mako Total Knee.
History and Design
The Stryker Triathlon Knee System has its roots in Stryker’s extensive history in orthopedic innovation‚ spanning over 30 years. The Triathlon system was designed to incorporate the best of Stryker’s previous designs‚ addressing common issues like instability‚ patellofemoral tracking problems‚ and loosening/osteolysis that can lead to revision total knee arthroplasty (TKA). The Triathlon Knee System is a testament to Stryker’s commitment to continuous improvement and understanding of the complex needs of patients and surgeons.
The Triathlon system is built upon the principle of working with the body‚ rather than against it.
