VERILAST◊ Knee Technology

Our LEGION CR Knee with VERILAST Technology was lab-tested to simulate the number of steps the average person takes in 30 years.1-7

If knee replacement is in your future, you've come to the right place to learn about one of the truly significant advancements in joint replacement materials in the past 20 years, VERILAST Knee Technology.

It's important to remember that not every knee implant is the same. VERILAST Knee Technology directly addresses one of the most commonly cited concerns associated with knee replacement implants, implant wear.

Whether or not to undergo knee replacement surgery is a very important decision. No matter how statistically safe and successful knee replacement surgery has proven to be, every surgery has risks. Before making any surgical decision, conversations should take place with your family, your primary care doctor and your orthopaedic surgeon to make sure that knee replacement with VERILAST Technology is the right course of action for your particular situation.

Important Testing Note

VERILAST knee wear testing and results apply only to the VERILAST LEGION CR Primary Knee System only. Extended lab-testing for other VERILAST knee systems have not been performed. The results of laboratory wear simulation testing have not been proven to predict actual joint durability and performance in people. A reduction in wear alone may not result in improved joint durability and performance because other factors, such as bone structure, can affect joint durability and performance and cause medical conditions that may result in the need for additional surgery. These other factors were not studied as part of the testing.

Important Safety Notes:

Knee replacement surgery is intended to relieve knee pain and improve knee functions. However, implants may not produce the same feel or function as your original knee. There are potential risks with knee replacement surgery such as loosening, fracture, dislocation, wear and infection that may result in the need for additional surgery. Longevity of implants depends on many factors, such as types of activities and weight. Do not perform high impact activities such as running and jumping unless your surgeon tells you the bone has healed and these activities are acceptable. Early device failure, breakage or loosening may occur if you do not follow your surgeon's limitations on activity level. Early failure can happen if you do not guard your knee joint from overloading due to activity level, failure to control body weight or accidents such as falls. Talk to your doctor to determine what treatment may be best for you.
