Biologically enhanced healing of the rotator cuff.

Abstract

Failure of rotator cuff repair is a well-documented problem. Successful repair is impeded by muscle atrophy, fat infiltration, devascularization, and scar tissue formation throughout the fibrocartilagenous transition zone. This case study exemplifies a technique to biologically augment rotator cuff healing. Clinically, pain and function improved. Postoperative magnetic resonance imaging evaluation confirmed construct integrity. Biological enhancement of the healing process and physiologically based alterations in rehabilitation protocols can successfully treat complicated rotator cuff tears. Prospective studies with larger sample sizes and continued follow-up are necessary to assess the definitive efficacy of this treatment modality.
