Total Knee Implants Designed With Women in Mind

totalkneewomen1Total knee replacement is one of the safest and most successful types of surgery; in well over 90% of cases, it is complication-free and results in significant pain relief and restoration of mobility.1

Stryker’s Triathlon® Knee System represents the contribution of over 30 years of clinical success in orthopaedic implants. It utilizes the latest in knee technology to help increase the extent to which you will be able to restore motion in your knee after surgery. The Triathlon® Knee is designed for natural knee movement, helping to relieve your pain and restore your independence.

Over 60% of total knee replacements are performed on women.2 Triathlon® was designed with women in mind.3 It’s a complete knee system designed to increase motion, decrease wear and fit a woman’s anatomy.

Increased Knee Motion

totalkneewomen4Restoring motion in your knee is likely one of the reasons you are considering knee replacement. Motion, the bending (flexing), straightening (extension) and rotation of your knee, affects your ability to perform everyday activities. The Triathlon® Knee System allows for natural knee motion and up to 150° of flexion.

totalkneewomen2Better Fit for Women

There are over 300,000 knee replacements done each year in the US1 and over 60% of them are performed on women. Triathlon® is a total knee system designed with women in mind.

The design of Triathlon® offers a wide range of sizing options that closely match both the female and male anatomy. The smaller sizes are narrower, and a narrower implant accommodates the female bone structure, which improves fit and function for women.

totalkneewomen3Improved Wear Performance

Many things including patient weight, activity level as well as the implant’s bearing surface technology, can affect the longevity of the implant. The bearing surface is defined as the two parts of the knee that glide together throughout motion.

Stryker’s advanced bearing technology, called X3®, has demonstrated a 96% decrease in wear in laboratory testing compared to competitive premium bearing technologies.1 Based on this testing, X3® Technology may result in a longer lasting implant. This technology is particularly important for younger patients.
