title: [Principles and peculiarities of the therapy of knee  joint fractures (author's transl)].
abstract: Some unfavourable and favourable peculiarities and principles have to be recognized in the therapy of intraarticular knee joint fractures. Apart from the self-evident necessity of an exact reconstruction of joint faces (more often than before conditioning the indication for arthrotomy) timely mobility can be reached by only adapting osteosynthesis, as in this region there is virtually no pseudoarthrosis. A defect in the articular face of the tibia can be replaced by a part of the patella. A shattered patella can be partially or totally extirpated and good function can be obtained if the extirpation prevents the remaining parts of the periosteum from developing a neopatella, limiting mobility and causing pain. The distal end of the femur can ideally be fixed with a condylar splint even in those cases where a number of fragments can only approximately be put together under the condition of knee joint face restitution. In order to restore the function, it is sometimes necessary to loosen and prolong the quadriceps tendon to achieve sufficient flexion if this is required by the living and working conditions of the injured person.
