Recurrent instability of the patella (RPI) is a multifactorial condition, which is challenging to manage particularly in skeletally immature patients [1,2,3].Risk factors associated with RPI are patellar height, patellar and trochlea dysplasia, rotational and coronal malalignment, malalignment of the extensor mechanism, and injuries to the medial patellofemoral ligament (MPFL) [4,5]. The purpose of this review is to present the most recent data concerning risk factors and their predictive value to estimate recurrent LPD risk.
