Abstract:
PURPOSE: To evaluate the effectiveness of the modified Elmslie-Trillat operation on recurrent and habitual patella dislocation. MATERIALS AND METHODS: From November 1993 to December 2000, 16 cases of modified Elmslie-Tril-lat operation were performed in 13 patients. Recurrent dislocation were 10 cases, habitual were 6 cases. Mean age was 26 years old(15~46) and male was 1 patient, female were 12 patients. We checked the Q angle and congruence angle to compare the postoperative state with the preoperative result by radiologic finding. Crosby and Insall's criteria was used to evaluate the clinical results. RESULTS: The congruence angle and Q angle were improved from average 46 degrees (10 degrees ~ 77 degrees) and 20.2 degrees(16 degrees ~35 degrees) in preoperative state to average -5 degrees (-10 degrees ~4 degrees) and 9.5 degrees(4 degrees~15 degrees) in postoperative state. Patella alta were 2 cases and patella baja was none in preoperative measurement. There was no change of patella alta in postoperative measurement. In Crosby and Insall 's criteria, 5 cases showed excellent, 10 cases good, l case poor result. At final follow-up, there were no postoperative complications such as degeneratve arthritis, nonunion, ROM limitation except 1 case of patellar redislocation. CONCLUSION: Modified Elmslie-Trillat operation is good alternatives to the recurrent and habitual patella dislocation.
