The Repaired Rotator Cuff: MRI and Ultrasound Evaluation

Area of Science:

• Orthopedic imaging
• Radiology
• Musculoskeletal imaging

Background:

• Postoperative assessment of rotator cuff repairs is crucial for patient outcomes.
• Understanding imaging findings after rotator cuff surgery aids in differentiating normal healing from complications.

Purpose of the Study:

• To review current practices in postoperative rotator cuff imaging.
• To describe imaging findings of normal and abnormal postoperative rotator cuffs.
• To identify common postoperative complications.

Main Methods:

• Review of current literature on postoperative rotator cuff imaging.
• Analysis of imaging findings from magnetic resonance imaging (MRI) and ultrasound (US).

Main Results:

• Repaired rotator cuffs frequently show abnormal appearances on MRI and US, which often normalize within 6 months.
• Capsular and bursal thickening decrease significantly in the first 6 months postoperatively.
• MRI and US show comparable accuracy in postoperative assessment, with lower sensitivity for partial tears.

Conclusions:

• Postoperative rotator cuff imaging, particularly MRI and US, is valuable for assessing repair integrity and detecting complications.
• Further investigation is needed for newer techniques like patch augmentation and superior capsular reconstruction.
• Clinically insignificant abnormal imaging findings can persist beyond 6 months.
