The medial patellofemoral ligament (MPFL) originates from the bony surface between the medial epicondyle of the femur and the tuberosity of the medial malleolus and ends at the upper portion of the medial border of the patella, restricting patellar external translation, and is the main static stabilizing structure of the patella. Injury to this ligament caused by patellar dislocation results in failure of the medial patellar limiting structure, often leaving patellar instability or recurrent dislocation. MPFL reconstruction restores the medial patellar static stabilizing structures and provides patellar stability and normal trajectory, but does not correct bony abnormalities. MPFL reconstruction can be performed in cases with clear indications after full evaluation of all pathologic factors leading to patellar dislocation. MPFL reconstruction techniques can be divided into non-anatomical and anatomical reconstruction, and anatomical reconstruction has become more popular recently. The key technique of anatomical reconstruction is to determine the original anatomical starting and ending points of MPFL. Different grafts and fixation methods can be used for reconstruction. Regardless of the method of reconstruction, the key is to restore the normal MPFL anatomy and maintain its isometric properties. In our department, 30 cases of patellar dislocation were treated with minimally invasive reconstruction of medial patellofemoral ligament in the past 5 years, and the follow-up results were significantly better than the traditional treatment techniques.
