1. A joint implant having a polymer component with a smoothened surface, wherein the polymer component is produced by:
placing a polymer workpiece in an explosion chamber;
closing the explosion chamber;
introducing a flammable gas mixture into the explosion chamber; and
igniting the flammable gas mixture, wherein a temperature that lies above the melting point of the polymer and in a range of 1500° C. to 2800° C. is produced in the explosion chamber by igniting the gas mixture for smoothening the surface of the polymer component, and wherein igniting the flammable gas mixture in the explosion chamber also treats the polymer component by deburring.
