Recurrent patellar dislocations are often caused by multiple pathologic and anatomic factors, including bony structural abnormalities, static ligament structural abnormalities, and dynamic muscle function abnormalities [1]. Conservative treatment has a high recurrence rate, and it is the consensus of most scholars to advocate surgical treatment [2]. However, the understanding of the mechanism of recurrent patellar dislocation varies, and there are many surgical options available, which can be divided into soft tissue surgery and bony surgery according to the tissue structure involved in surgery, and can be roughly divided into proximal rearrangement of the knee extensor device, distal rearrangement of the knee extensor device, and combined distal and proximal rearrangement of the knee extensor device according to the site involved, and there are still large differences in the choice of treatment modality [3 and 4]. In recent years, with the understanding of the biomechanics of the medial patellofemoral ligament (MPFL), MPFL reconstruction has become the most central procedure in the series of surgical modalities for the treatment of recurrent patellar dislocation, with an increasing number of successful reports [5-7]. However, reports on the surgical approach of MPFL reconstruction vary and still hold different opinions on graft selection, choice of fixation point, choice of fixation method, and graft tension [3,8,9]. We used minimally invasive MPFL double bundle anatomical reconstruction and lateral support band release with the assistance of autologous semitendinosus tendon arthroscopy to treat recurrent patellar dislocation.
