Patellar Glide (Adapted with permission from: Rossi R, Bruzzone M, Dettoni F, Margheritini F: Clinical examination of the knee. In: Orthopedic Sports Medicine, Principles and Practice. Edited by Margheritini F, Rossi R. Milan: Springer; 2010).The glide test is performed with the knee flexed at 30°: if the patella glides laterally over 75% of its width, a medial restraints laxity is diagnosed; while when it glides less than 25%, lateral restraints tightness is predicted.
