Objective To evaluate arthroscopy-assisted release of the lateral retinaculum and reefing of the interior retinaculum for treatment of recurrent patello-femoral joint dislocation.Methods From January 2003 to December 2008, 78 cases of recurrent patello-femoral joint dislocation were treated under arthroscopy.They were 23 men and 55 women, with a mean age of 20.3 years (range, 11 to 45 years).Their recurrence of dislocation averaged 5 times.Operative release of the lateral retinaculum and reefing of the interior retinaculum were performed under arthroscopy for all the patients.Auxiliary Goldthwait-Roux procedures were conducted in addition in 13 cases, and auxiliary improved Goldthwait-Roux procedures in 26 cases.We evaluated their subjective symptoms and objective signs, recurrence of patello-femoral joint dislocation, X-ray examinations and functional rehabilitation of the knee joint during the first 3 months, and at 6 and 12 months postoperation.Results Of the 78 cases, 65 were followed up for a mean of 47.3 months (from 19 to 76 months).All the patients were satisfied with the therapeutic effect.Recurrence of dislocation was no longer observed.Seven cases experienced slight pain after excessive motion.The flexion was slightly limited in 5 cases.Six cases reported a sense of patello-femoral malposition.By the Bostman evaluation system, the 65 cases scored 18.5 ±4.5 and 27.5 ±2.5 before and after surgery respectively, showing a statistically significant difference(P=0.018).B...
