Abstract:
BACKGROUND:Arthroscopy can observe the involutive relation of patelofemoral joint directly and dynamicaly, which can be used to judge whether the patelofemoral joint abnormalities can be completely corrected. OBJECTIVE:To analyze the clinical effect of lateral retinacular release and ligament reconstruction under arthroscope for patela recurrent dislocation. METHODS: A total of 58 patients diagnosed as having recurrent patelar dislocations were divided randomly into control and experimental groups, with 29 cases in each group. Patients in the control group received lateral retinacular release and ligament reconstruction under common operation and those in the experimental group received lateral retinacular release and ligament reconstruction under arthroscopy. RESULTS AND CONCLUSION:There was no significant difference in the Lysholm and Kujala scores before treatment in the two groups (P > 0.05), but at 12 months after treatment, the Lysholm and Kujala scores were both increased in the two groups, especialy in the treatment group (P < 0.05). No difference was found in the congruence angle and lateral patelofemoral angle with CT value at 30° of knee flexion (P > 0.05), and CT measurement values of the congruence angle and lateral patelofemoral angle were both decreased in the two groups, especialy in the experimental group, at 12 months after treatment. In addition, the operation time, healing time, and total effective rate were better in the experimental group than the control group (P < 0.05). These results indicate that the lateral retinacular release and ligament reconstruction under arthroscopy has a better effect on recurrent patelar dislocation.
