Abstract: The invention is relative to a roller bracket for cooperation with a cylindrical paint roller, comprising a handle and a bracket rod, and is also relative to a roller end piece. The roller end piece is wheel-shaped and has a substantially cylindrical envelope surface and a bearing for mounting on the bracket rod, wherein two roller end pieces are mounted on the bracket rod. An outer roller end piece is arranged at the end of the bracket rod and an inner roller end piece, which comprises a carried wheel with a push-off element, is arranged at distance form the outer roller end piece for removably carrying a respective end of paint roller on its respective substantially cylindrical envelope surface.

Abstract: A method of designing a guide tool for cartilage repair in an articulating surface of a joint, comprising the steps of: I. determining physical parameters for cartilage damage in a joint and generating design parameters for cartilage repair objects and their relative placement in a predetermined pattern, comprising: II. selecting repair objects to fit the individual cartilage damage site wherein the repair objects have: cross sectional areas adapted to fit the surface area of the cartilage damage site, lengths adapted to fit the selected joint and/or type of cartilage damage, and surfaces intended to align with the articular cartilage surface in the joint, based on the healthy surface contour curvature, III. determining, based on obtained image data, positions and angles of the selected cartilage repair objects, wherein the positions and angles are adapted so that the selected repair objects fit the individual cartilage damage site, IV.
