[Surgical treatment of chronic recurrent patella dislocations. Surgical procedure and results].

This is a report about a simplified operative technique of discission of the lateral retinaculum and vastus and medial drawing tight of the capsule. After the end of growth there will be always a medial transfer of the tuberositas tibiae at the same time by an undermining technique of osteotomy and osteosynthesis with a traction screw. Evaluation of our own 135 cases (1964-1981) with 27 only soft-tissue-operations and 108 combined operations by longterm-observations or recent control (115 cases with average observation period of 5,9 years). The number of reluxations of the patients, who had only a soft-tissue-operation, was as high as other reports; the primary number of reluxations after the combined operation was much lower (6,7%). By further conservative treatment or sometimes second operation none of our patients had any longer reluxations of the patella.
