From July 1983 to August 1986, arthroscopic lateral release was performed in sixteen patients (sixteen Rnees) of subluxation syndfrome of the patella. Their mean age at the time of operation was 20.1 years with a range from 12 to 20 years. Eight patients had osteochondral fracture of the patellar medial facet. Fragments of all patients were removed arthroscopically.Fifteen patients were available for follow up. The follow up interval ranged from three months to three years and four months (mean, 12.7 months).Roentgenographycal results were satisfactory in all patients, but clinical results were unsatisfactory in two patients (follow up interval of one patient was seven months and another was eight months). These patients were unable to play sports at the time of follow up.Arthroscopic findings of these patients showed more remarkable changes of chondromalacia patellae than those of other patients, and physiological findings showed remarkable genu valgum, and roentgenographycal findings showed remarkable dysplasia of the patellar groove.
