Prosthetic Alternatives Enhance Lifestyle Capacity
February 15, 2008 – 3:22 pmThe excitement is growing at the Neurologic and Orthopedic Hospital of Chicago as we get ready to introduce the Hi-Flex Mobile Bearing Knee this February, to the best of our knowledge for the first time in the U.S. Until now, a good outcome for knee replacement was the ability to restore up to 115-120 degrees of motion post operative. The major patient complaint though in over 15% of knee replacement recipients has been pain or stiffness. I started working with the Mobile Bearing Knee outside of the United States in 2001 as a visiting professor to countries that demand the utmost in pain relief and motion following knee replacement surgery. Because of my knowledge and interest, I was chosen as a clinical investigator in 2003 and as a result, I have been granted the privilege of adding the Mobile Bearing Knee to the prosthetic alternatives offered at NOHC.

Flexion greater than 120 degrees significantly adds to lifestyle capacity and recreational performance be it level gait, stooping, squatting, climbing stairs, bowling, playing golf, riding a bike, skiing, etc., etc., etc. So why the delay in FDA approval; why availability outside U.S. first?
The concern of the FDA and the orthopedic surgical community has been accelerated wear at the knee articulating surfaces of which there are two in the Mobile Bearing Concept and one in the fixed bearing design. The latter has been the standard but with 15% lack of patient satisfaction because of permanent stiffness after the surgery.
Our research has documented that improved resistance to wear, delaminating, and posterior loading fatigue of highly cross linked UHMWPE inserts will result in improved motion for the total knee replacement patient without the risk of early failure. TheHi-Flex Mobile Bearing Knee is now FDA approved and you can enjoy the more successful outcomes at NOHC
