[Corrective osteotomy of the leg - comparison of two types of postoperative treatment.]

The author describes his experience with the immediate postoperative mobilization of the knee joint after high arc-shaped corrective osteotomy of the leg. The latter was indicated on account of a varus deformity of the knee with subsequent arthritis. The author compares the method with treatment by means of a plaster tube in the same indication and discusses the advantages of preserving the mobility of the knee joint. This is made possible by a special way of application of the plaster with articular metal splints. The maun asset is in the author's opinion the markedly reduced period of hospitalization and greater comfort of the patient. It eliminates rehabilitation needed to overcome the post-fixation stiffness of the knee which is always necessary when the traditional rigid fixation is used. Key words: high arc-shaped osteotomy of the leg, mobile knee joint, shorter hospitalization.
