Abstract

Background: To compare patient reported outcomes, range of motion (ROM), and complications of patients undergoing arthroscopic rotator cuff repair (RCR) augmented with a bioinductive patch compared to standard repair. Methods: A retrospective review was conducted of patients undergoing primary RCR with and without bioinductive bovine collagen patch augmentation for MRI or Ultrasound confirmed supraspinatus/infraspinatus tears from 2016 to 2021. Exclusion criteria included the following: open RCR, ipsilateral shoulder surgery, active infection, or less than 6-week postoperative follow-up. Patch RCR was matched 2:1 to controls based on age, sex, BMI, tear size, and the number of tendons involved. Patient Reported Outcome Information System (PROMIS) for upper extremity function (-UE), pain interference (-PI), and depression (-D) scores were recorded up to 2 years. Results: Overall, 81 patients underwent RCR with patch augmentation and were matched to 162 controls. No significant differences were found between groups in terms of age (p=0.62), sex, smoking, diabetes, partial vs. full-thickness tears, and tear size. ROM in forward-flexion (FF) and abduction were significantly increased at 6-month follow-up for the augmented group compared to controls (FF 156.8±21.6 vs. 148.1±23.2 degrees, p<0.01; abduction 133.1±33.2 vs. 114.1±36.5 degrees, p=0.019) but not at 1-year follow-up. No differences were seen for PROMIS-UE, PROMIS-PI, or PROMIS-D scores. The augmented group had ten complications (12.3%) and the control had 20 (12.3%). The augmented group had four retears (4.9%) of which three required revision compared to 11 retears for the control (6.8%) of which eight required revision. The augmented group had six cases (7.4%) of adhesive capsulitis, five of which took place in mid-late 2020, compared to the four cases (2.5%) of adhesive capsulitis (three before mid 2019 and one in early 2021) seen in the control and all patients underwent manipulation under anesthesia. Conclusions: Bioinductive patch augmentation for RCR demonstrated increased ROM at six months and equivalent physical function, pain in daily life, and depression levels at 2 years when compared to standard RCR. There was a lower retear rate in the augmented group compared to the controls. The increased incidence of postoperative adhesive capsulitis in the augment group is a concern and needs to be further evaluated.
