Triathlon® Knee System
Knee Implants That Promote Easier Motion1,2,3
Stryker knee replacements are different than traditional knee replacements because they are designed to work with the body to promote easier motion,1,2,3 and a study has shown a more rapid return to functional activities after surgery.2 This is due to the single radius design of the knee implant. Single radius means that as your knee flexes, the radius is the same, similar to a circle, requiring less effort from your quadriceps muscle.1,4,7
Because the thigh muscle (the quadriceps) is attached to your knee, it is unavoidably involved in the surgery. Therefore, the quadriceps muscle can become a source of discomfort or pain during your recovery period. The quadriceps muscle plays an important role in your ability to move your legs so it also has a major impact on your recovery and how quickly you can get back to living your life.2
Knee Implants Designed to Last Longer5
Several factors influence how long an implant will continue to perform. Stryker knees are designed to resist wear in many ways — they use advanced bearing surfaces; they're balanced to help avoid excessive stress in any one spot; and, they're sized to better fit your personal anatomy.
The durability of knee implants depends on many things including patient weight and activity level, as well as the implant's bearing surface technology. The bearing surface is defined as the two parts of the knee that glide together throughout motion. Stryker developed the Triathlon Knee System with X3 Advanced Bearing technology. Based on laboratory testing, Stryker's Triathlon Knee with X3 technology has demonstrated a lower wear rate which may result in a longer lasting implant.5 X3 is a patented technology only offered by Stryker.
Better Results in Knee Replacement6
The Triathlon Knee has Better Results than other knee implants when measuring revision rates on the National Joint Registry of England and Wales.6 Let's take a look at how Stryker's Triathlon Knee with X3 technology compares to other knee implants.
