Each year about 430.000 patients in the European Union have a total hip or knee joint replacement to provide relief from crippling joint diseases such as arthritis. The survival time of current hip and knee implants rarely exceeds fifteen years due to the generation of tremendous numbers of predominately sub-micron-sized polyethylene wear particles, eventually leading to implant loosening. The project aims to provide more durable implant joints with substantially longer lifetimes and to reduce the need for subsequent surgery. Two areas of advanced surface technology, sol-gel and High Velocity Oxy Fuel thermak spaying, will be developed to ammow the deposition of novel hybrid coatings of ceramic-polymer composite. Such coating will be used to eliminate or reduce debris generation from UHMWPE in the hip joint, and to provide a coated metal alternative to UHMWPE for knee, hip and other orthopedic wear couples.
