[Results of knee joint arthrolysis surgery (author's transl)].

This work reports the results of operative treatment of knee-stiffness from 1973-1981 in the Department of Orthopaedic Surgery, University Kiel. 42 out of 46 occurrences of age, were post-operatively controlled. In most cases the stiffness was of traumatic origin. In more than one half of the cases the pre-operative controlled. In most cases the stiffness was of traumatic origin. In more than half of the cases the pre-operative degree of motion was less than 60 degrees. Intraarticular revision alone or extraarticular revision alone or a combination of both and other bone surgery was performed in approximately 1/4 of the patients respectively. The absolute range of motion, an average of 58 degrees pre-operatively, improved to 114 degrees post-operatively. The mean relative improvement of motion, in regard to a norm of 140-0-0 degrees, was 68% at discharge. Among our patients complication were seldom. In our opinion operative arthrolysis in indicated cases is a tried and proven method for treatment of stiff knees.
