At least one compensation element has an element rear side and, lying opposite along the proximal-distal axis, a contact face for contacting a lateral condyle and/or medial condyle. A connection system has at least one connection portion on the reference block. At least one complementary connection portion is disposed on the compensation element. The connection system is configured to releasably attach the compensation element on the block front side. The compensation element in the attached state does not completely cover the block front side. The connection system is configured so that the compensation element is attachable in different positions on the block front side by the connection system.
