[Conventional x-ray diagnosis of the knee joint following surgical repair of ligament injuries and after ligament replacement plasty].

Characteristic radiological findings following operative repair of the ligaments of the knee joint are described and related to the type of operative procedure. The operations depend on a number of basic principles which are discussed in detail. The majority of these surgical procedures are not apparent radiographically. It is only by having a knowledge of the individual procedures and of the resulting functional changes in the knee joint, that the informed radiologist can make a correct assessment of the post-operative radiographs. Defects resulting from bone drilling can be recognised tomographically in the early postoperative phase, or if they persist for any reason. This could be confirmed by experiments on pigs' knees.
