Abstract:

BACKGROUND: Clinically for the treatment of patellar instability, can be divided into conservative method and surgical method. There are so many surgical treatment, each one has focus and inadequate. However, there is still no unified consensus on which method should be used for the treatment of patellar instability.
OBJECTIVE: To investigate the application of anatomical double bundle reconstruction of medial patellofemoral ligament for the treatment of patellar dislocation through autologous tendon graft.
METHODS: A total of 46 patients that had been treated with arthroscopic double bundle medial patellofemoral ligament reconstruction by using the semitendinosus tendon for patellar dislocation in the Department of Orthopedics, First Affiliated Hospital of Anhui Medical University.
RESULTS AND CONCLUSION: All cases were followed-up for 2-16 months and the patient’s range of motion and stability were assessed. During follow-up, no patients had serious complications, and all patients gained normal knee activity, except 1 case straight restricted. No patellar dislocation occurred postoperatively. The mean Lysholm score and the Kujala knee function score postoperative were improved compared with those preoperative (P < 0.01). This study concludes that medial patellofemoral ligament with anatomical double bundle reconstruction using the semitendinosus tendon for the treatment of patellar dislocation is an effective method.
