The invention also relates to a set comprising two of said devices, whereby the first device is intended for forming the articulation surface of a first articular spacer and the second device is intended for forming the articulation surface of a second articular spacer, whereby the two articulation surfaces touch against each other and form the sliding surfaces of the articular spacer in the patient-inserted state such that the articular spacer assumes the function of the bones of the respective joint, preferably of a knee joint. Moreover, the invention also relates to the use of said device and a method for producing an articular spacer on a bone (19), in particular the bone surface, comprising the following chronological procedural steps: A) Applying a bone cement to a prepared bone B) Pressing said device onto the bone cement and C) Detaching the device from the cured bone cement.1/6 2 1 2 3
