The patellofemoral joint is complex, and the management of the first patellar dislocation is not well decoded. The progression to recurrent instability is common. Bony anatomy, muscle tone, and soft tissues are essential stabilizers to preserve the physiological patellar tracking, and they should be carefully evaluated when facing patients with instability. © 2022 Professor P K Surendran Memorial Education Foundation.
