Classification of RCT using shoulder MR imaging is traditionally based on tear width and thickness, not arthroscopic classification. However, for surgical RCT repair, arthroscopic classification is more useful because the surgical method depends on the classification type. For example, U-shaped tears can be repaired by margin convergence whereas crescent-shaped tears can be repaired directly by a tendon-to-bone technique. We believe the ability to determine surgical classification of RCT type with preoperative MR imaging could be helpful, especially with recently introduced three-dimensional (3D) MR sequences.
