Biomechanically the knee joint has motion complex which includes gliding, rolling, translation, and rotation during their extension to flexion. A significant incidence of knee pain and disability arises from patellofemoral disorders in all ages. Patellar instability is a subjective term that defines pain, blockage, and clinical twisting due to the deterioration of the static and dynamic knee extensor mechanism. An accurate diagnosis relies both on assessing soft tissues and bony tissues together andconsidering pelvic and spinal stabilizers. Under the title of patellar instability, arthroscopic medial plication technique and the importance of the medial patellofemoral ligament in this approach will be discussed.
