Wear mechanisms of UHMWPE under physiological conditions In 2005 one of the giants in implant manufacturing launched the most flawed metal on metal implant. It caused a loss of billions of dollars and more than 8000 patients were forced to a revised surgery because of the high health hazard. At present, polymer on metal implants comprise of 70% of all hip and knee arthroplasty. Increased life expectancy and lower revision surgeries due to wear induced osteolysis are driving development of superior grades of UHMWPE. Since 1970s, the procedure for the development of new orthopaedic bearings initiates with screening of several candidate ... Read More
