Abstract:[Objective] To compare the clinical efficacy of medial patellofemoral ligament (MPFL) reconstruction by suture anchor ver- sus double bone tunnel fixations on patellar side for recurrent patellar dislocation. [Methods] A retrospective study was done on 42 patients who received MPFL reconstruction for recurrent patellar dislocation in our department from January 2016 to December 2020. According to doctor-patient communication, 23 patients had tendon graft fixed on the patellar side by suture anchors, while the other 19 patients were double bone tunnels. The perioperative, follow-up and imaging documents were compared between the two groups. [Results] All patients in both groups were operated on successfully without serious complications. The anchor group consumed significantly shorter operation time than the tunnel group (P＜0.05) . During the follow-up lasted for more than 12 months, all patients in both groups achieved good functional recovery without patellar dislocation again, except one case in the tunnel group who got patella fracture. The anchor group resumed full weight-bearing activity significantly earlier than the tunnel group (P＜0.05) . The Kujala and Lysholm scores, as well as knee extension-flex- ion range of motion (ROM) increased significantly (P＜0.05) , whereas VAS score decreased significantly (P＜0.05) in both groups over time, whereas which proved not statistically significant between the two groups at any corresponding time points (P＞0.05) . Radiographically, the patellar title (PT) and patellar displacement (PD) were significantly reduced in both groups after surgery compared with those before surgery (P＜0.05) , which were not significantly different between the two groups at any corresponding time points (P＞0.05) . [Conclusion] Both the patellar fixation methods have achieved satisfactory clinical outcomes in MPFL reconstruction. In comparison, the anchor fixation has the advantages of shortening operation time, reducing complication risk and enhancing recovery.
