Patellar dislocation is a common disease in orthopaedics. The incidence of patellar dislocation is the highest in adolescents with an average age of 21.4 years. There are many methods to treat the dislocation of patella, among which the reconstruction of medial patellofemoral ligament (MPFL) is the main one. In this paper, the biomechanics and graft selection of medial patellofemoral ligament reconstruction were discussed in detail by reviewing the relevant literature at home and abroad. The femoral insertion, patellofemoral fixation and postoperative complications were also discussed, in order to provide reference for clinical workers. In view of different postoperative complications, there are many kinds of optimization schemes, and reasonable choice of operation scheme is the premise of good operation satisfaction rate.
