Abstract:Objective: To retrospective a patellar end insertion repair method of Medial Patellofemoral Ligament (MPFL) to primary patellar dislocation in adolescents with osteochondral fracture. Methods: From January 2014 to June 2017,12 cases of acute primary patellar dislocation from Second Affiliated Hospital of Xi'an Jiao Tong University were enrolled in the study,including 7 males and 5 females,with an average age of 14±3.1 years years (11~17 years old), 9 left knees and 3 in the right. All the patients were treated within 2 weeks after injury surgical treatment was performed under general anesthesia, After internal fixation of osteochondral fracture,2 suture anchors were inserted into the upper 1/3 of media side of patellar to repair MPFL,and suture the injury side of MPFL on the medial patella. The apprehension sign and patellar hypermobility were compared at 6 months and last follow-up. Patients were evaluated postoperatively with the Kujala scoring questionnaire,Lysholm scores and Tegner scores . Results: All patients were followed up for 12~16 months (average 14.2±2.5 months), 2 patients were positive apprehension sign and patellar hypermobility, no recurrent dislocation occurred. Lysholm, Kujala and Tegner scores were significantly increased (P<0.05), and the knee joint function recovered well at last follow-up. Conclusion: MPFL patellar end suturing repair method is simple and minimally invasive for the treatment of primary dislocation of patella in adolescents with osteochondral fracture.
