Increasing age is associated with decreased physical activity after surgical stabilization, and therefore in growing and very active athletes early surgical treatment intervention needs to be considered. Reconstruction of the MPFL (medial patellofemoral ligament) in patients with minor trochlear dysplasia is technically possible without interfering with distal growth plate of the femur,[8] however, large studies are missing. Osseous articular correction before epiphyseal closure is contraindicated.[9]
