Abstract
A coated prosthetic implant and a method of forming a continuous coating of highly crystalline polymer over a prosthetic implant by means of passing particles of polymer through a high temperature plasma and subsequently depositing the molten particles over the implant surface. This invention is especially useful for coating polymer composite implants, such as a femoral insert for a hip joint prosthesis, with a coating of poly (aryl-ether-ketone).
