Clinical observation of arthroscopic assisted double bundle medial patellofemoral ligament reconstruction for recurrent patellar dislocation

Objective To investigate the clinical effect of arthroscopic reconstruction of medial patellar ligament for recurrent patellar dislocation. Methods The clinical data of 29 patients with recurrent patellofemoral dislocation treated by arthroscopic assisted double bundle reconstruction of medial patellofemoral ligament from January 2017 to June 2019 in Jingzhou Central Hospital of Hubei Province were retrospectively analyzed, including 10 males and 19 females, with an average age of 19.4 years (range, 14.0-29.5 years). TT-TG distance and patellar inclination angle were measured by CT. The Caton index was calculated. Kujala and Lysholm scores were used to evaluate knee joint function before and after operation. Results All patients were followed up for 12 to 36 months. The TT-TG distance was less than 20 mm, patella tilt angle was less than 20° and Caton index was 0.9-1.1 before operation. There was no recurrence of dislocation in all patients. The preoperative and postoperative Kujala scores were (51.32±5.52) and (82.45±3.38). Lysholm scores were (53.25±5.85) and (89.65±4.75). The preoperative and postoperative patellar tilt angle was 13.15°±1.67° and 6.94°±1.47°. The differences were statistically significant (P<0.05). Conclusion Arthroscopic assisted double bundle reconstruction of medial patellofemoral ligament for the treatment of recurrent patellar dislocation without serious bony abnormality is simple, effective, with few complications, and no recurrence in recent follow-up, which can significantly improve the knee joint function.
