Abstract
The patellofemoral joint (PFJ) is a complex articulation between the patella and the femur, in-volved in the extensor mechanism of the knee. Patellofemoral disorders can be classified into ob-jective patellar instability, potential patellar instability, and patellofemoral pain syndrome. An-atomical factors such as trochlear dysplasia, patella alta, and tibial tuberosity-trochlear groove (TT-TG) distance contribute to instability. Patellofemoral instability can result in various types of dislocations, and the frequency of dislocation can be categorized as recurrent, habitual, or per-manent. Primary patellar dislocation requires diagnostic framing, including physical examina-tion and imaging. Magnetic resonance imaging (MRI) is essential for assessing the extent of damage, such as bone bruises, osteochondral fractures, and medial patellofemoral ligament (MPFL) rupture. Treatment options for primary dislocation include urgent surgery for oste-ochondral fragments or conservative treatment for cases without lesions. Follow-up after treat-ment involves imaging screening and assessing principal and secondary factors of instability. Detecting and addressing these factors is crucial for preventing recurrent dislocations and opti-mizing patient outcomes.
