| Objective: To compare the clinical curative effects of patella single tunnel and double tunnel to reconstruct the medial patellofemoral ligament in the treatment of recurrent patellar dislocation. Methods: From June 2010 to May 2016, chose 47 cases of patients with recurrent dislocation who receipted the patella reconstruction of medial patellofemoral ligament in arthroscopic as the research objects, according to the different treatment methods, they were divided into the patella single tunnel reconstruction group with 22 cases and the patella double tunnel reconstruction group with 25 cases. After the operation, recorded the number of re-dislocation, the inclination angle of patella and the Kujala scores of the two groups to evaluate the knee joint function. Results: All the patients were followed up for more than 12 months, the average followed up time was 39 months, with no dislocation cases. After the treatment, Kujala scores of two groups were higher than that before treatment, the differences were statistically significant, P＜0.05; and the difference between two groups’ Kujala score after treatment was not statistically significant, P＞0.05; after the treatment, the patellar tilt angle of two groups of patients were reduced, the differences were statistically significant, P＜0.05; and compared the two groups’ patellar tilt angle after treatment, there were no statistically significant differences, P＞0.05. Conclusion: The patella or single tunnel double tunnel reconstruction of medial patellofemoral ligament can restore the stability of patellar, improve the knee function. And the evaluation of clinical efficacy of two surgical methods has no significant difference, but compared with the double tunnel reconstruction method, single tunnel reconstruction method is simple, and with less trauma and shorter operation time, therefore, the patella single tunnel reconstruction is more conducive to clinical application. |
