Abstract
PURPOSE: This study aims to report the long-term results of lateral release and medial plication in patients with recurrent patellar dislocation. METHODS: In this study, 31 patients who underwent surgery for recurrent patellar dislocation were retrospectively reviewed between 1994 and 2004. Among the 31 patients were 12 male and 19 female patients. The average age was 23.9 ± 4.8 years, and the mean follow-up period was 11.6 ± 2.4 years. RESULTS: Three patients had postoperative dislocations. The mean Kujala score significantly improved from 57.5 ± 13.2 points preoperatively to 89.2 ± 8.7 points at the final follow-up (P < 0.0001). The median Tegner activity score significantly improved from 3 (range, 1-5) at preoperative examination to 7 (range, 3-9) at the final follow-up (P < 0.0001). Ten patients were rated as excellent, 18 as good, 2 as fair, and 1 as poor. The congruence angle improved from 16.5° ± 3.0° to -2.8° ± 2.7°, and the lateral patellofemoral angle improved from -4.2° ± 1.9° to 8.2° ± 2.5°. There was no case of osteoarthritis at the final follow-up. CONCLUSIONS: Percutaneous lateral release and medial plication showed satisfactory results with limited morbidity in the long-term follow-up. This traditional method remains a simple and effective surgical procedure for recurrent patellar dislocation. LEVEL OF EVIDENCE: Therapeutic, Level IV.
