28 July 2010 - Ceramic coated knee ( OxiniumTM) is a revolutionary new alloy that provides improved wear characteristics in knee replacement and could last twice as long as standard devices A breakthrough in knee replacement technology from orthopaedic specialists, Smith & Nephew, means that millions of people who suffer with arthritis in India & elsewhere can now benefit from the new Ceramic coated knee, which could last their lifetime due to its superior strength, high wear resistance and endurance. It also means that younger patients who have suffered severe pain and immobility while waiting years to be offered a knee replacement, may no longer have to.

Hip replacements had very significant breakthroughs over the last decade with the introduction of wear resistant bearing of ceramics and metal on metal. This enabled surgeons to cater to young and active patients. In contrast knee replacements had no breakthrough in materials over the last 40 yrs. The only significant improvement in TKR was in designs to allow high flexion. (High flex designs without material improvement of the bearing couple could lead to a high wear situation and patients were advised to engage in high flexion activities in a very limited way.)

The high performance bearings of the hip could not be applied to the knee because of its unique anatomy.

Metal on metal would not work as it is not a ball and socket joint and ceramics would break as only thin implants can be used in the knee.

Finally the breakthrough has been achieved with the ceramic coated knee. OxiniumTM material is a unique and advanced bearing product technology created through manufacturing process that transforms the surface of the native metal to a ceramic. This results in a material that incorporates the best features of ceramic and metal. It has the strength of a metal prosthesis but showing the wear characteristics of a ceramic. Finally younger and active patients in India can look forward to relief from their painful arthritic knees.
