DelBello SM, et al. - This study was undertaken to investigate the significance of initial and residual rotator cuff tear defect size on the need for revision surgery in a consecutive group of patients undergoing partial repair of massive rotator cuff tears. Researchers performed a retrospective chart review for all arthroscopic rotator cuff repairs conducted by a single surgeon between January 2013 and December 2016 (n=1,954). They assessed the cross-sectional area of the initial and residual tear defect was arthroscopically, and patients were followed postoperatively for a minimum of 2 years (mean 4.5 years). This consecutive series indicates that after index surgery, partial repair of massive rotator cuff tears proved to be a durable intervention with only 5.2% of patients requiring subsequent surgical intervention at an average follow-up of 4.5 years. It was shown that larger residual rotator cuff defects did associate with the necessity for subsequent nonoperative interventions. Nevertheless, no association was found between residual cuff defect size and the need for revision surgery. Partial repair of massive cuff tears was found to be a viable option when managing these complex patients and preserves the option for more invasive salvage operations if required.
