Recurrence of Patellar Instability in Adolescents Undergoing Surgery for Osteochondral Defects Without Concomitant Ligament Reconstruction

Abstract

If the MPFL is not reconstructed during index loose body treatment, children have a 61% recurrent instability rate. Patients with TT-TG distance greater than 15 mm, and particularly greater than 20 mm, are at highest risk for recurrent instability.
