Imaging of the rotator cuff following repair: Human and animal models

Abstract

Imaging of the rotator cuff following repair may be challenging due to the type of fixation, surgical manipulation of the tissue and the presence of residual defects that may exist in the presence of good functional outcome. Both ultrasound and magnetic resonance (MR) imaging present unique advantages in evaluation of the postoperative tissue. MR imaging has superior soft tissue contrast and provides a more global shoulder assessment, including the degree of arthrosis, while ultrasound enables a more dynamic testing of the repaired tissue. Power Doppler ultrasound and new contrast agents provide insight into the degree of vascular recruitment following repair.
