Level III, case-control.

AHD<6 mm is a sign of rotator-cuff rupture almost systematically involving longstanding total infraspinatus tear, not always amenable to suture repair due to advanced fatty degeneration. AHD equal to or greater than 6mm is of no diagnostic relevance and in no way indicates whether there is subscapularis tear and, if so, whether suture repair is feasible.

The present study introduces a new method to measure the SPE with the use of MRI. The evaluation of the functional engagement of the patella with the femoral trochlea in the sagittal plane can serve as a supplementary tool to the existing methods of evaluating patellar height, and may help to better identify the cases where inadequate engagement is recorded despite the absence of patella alta, so that the need for tibial tuberosity osteotomy may be re-assessed.

The precise extent of acute cellulitis and the presence of necrotizing soft-tissue infections can be determined with MR imaging, particularly on T2-weighted images.

Thirteen-megahertz ultrasound is a valuable tool for diagnosing LS. Morphological ultrasound diagnostic criteria had a high specificity and a high sensitivity.
