Patella dislocation is one of the most common pathologies of the knee joint. The incidence of patellar dislocation is 5.8–77.8 in 100,000 [1]. The medial patella-femoral ligament (MPFL) plays a pivot role in patella-femoral instability. All the acute dislocations cause some degree of macroscopic MPFL damage [2,3], and the studies show that a lateral dislocation is impossible without damage to MPFL. Forty-four percent of the nonconservative treatment patients go on to suffer redislocation [4], along with painful symptoms of chronic instability. The MPFL usually ruptures at its femoral origin upon lateral dislocation of the patella, typically under a rotational force with the knee extended. Up to 94% of patients suffer from MPFL rupture after acute patella dislocation. Over 130 distinct techniques for alleviating the patella-femoral instability and pain of all the origins have been described since 1915...
