Published results showed anteromedialization tibial tubercle osteotomy with medial patellofemoral ligament imbrication decreased the risk of recurrent patellofemoral instability among patients with trochlear dysplasia.

Alan L. Zhang, MD, and colleagues retrospectively collected recurrent dislocation events, KOOS score, WOMAC index, Kujala scores and satisfaction of 31 patients with trochlear dysplasia who underwent medial patellofemoral ligament imbrication and concomitant anteromedialization tibial tubercle osteotomy for recurrent patellofemoral instability. Researchers also collected patient demographic information, including age at the time of surgery, sex, BMI, tibial tubercle-trochlear groove distance and grade of trochlear dysplasia.
