Anatomical Medial Patellofemoral Ligament Reconstruction in Management of Cases of Patellar Instability

medialis obliquus, is the main passive stabilizer of the patellofemoral joint. Recently, it has been shown that the medial patellofemoral complex is the main pathoanatomy after patellar dislocation [1-3] . In addition, biomechanical studies have demonstrated that the MPFL is the main restraint against lateral patellar displacement and that repair or reconstruction of the MPFL restores normal patellar tracking [4-8] . Since it is known that distal realignment procedures do not restore patellofemoral stability and can even increase the medial patellofemoral pressure, leading to arthrotic degeneration [9] , surgical interventions have focused on the passive joints stabilizers. Furthermore, lateral release procedures have been shown to increase patellofemoral instability in biomechanical investigation and thus reconstruction or repair of the MPFL has became the preferred treatment [10] .
