An Advanced Option for Women
The knee is complex because the surfaces roll and glide against each other as the knee joint bends. In addition, the knee actually rotates slightly during both deep bending and normal activity.1,2
For women, rotation is especially important because women’s knees rotate more than men’s during deep knee bending.1 Rotation is important for walking, kneeling to garden, sitting to drive or travel, exercising, yoga, kneeling in church, climbing stairs, and playing with children or grandchildren.
DePuy offers a knee implant designed to bend, rotate, and allow for deep flexion: the Rotating Platform Knee. Unlike traditional implants, knees with a Rotating Platform are able to both bend and rotate, which helps accommodate for more normal movement.
Your surgeon will evaluate your mobility, as well as your rehabilitation goals, to determine if you are a good candidate for a Rotating Platform Knee. Rotating Platform Knees are proven to reduce implant wear by 94% over traditional knee implants.3 Also, patients followed for several years in a DePuy Orthopaedics multi-surgeon study reported a 97% satisfaction rate with their Rotating Platform Knee Replacement five years after surgery.4
IMPORTANT SAFETY INFORMATION
The way a knee replacement will perform depends on your age, weight, activity level, and other factors. There are potential risks, and recovery takes time. If you have conditions that limit rehabilitation, you should not have this surgery. Only an orthopaedic surgeon can tell you if knee replacement is right for you.
