Despite the widespread use of arthroscopic double-row transosseous-equivalent (TOE) rotator cuff repair (RCR) techniques, midterm outcome data are limited. The purpose of this article was to assess midterm clinical outcomes of patients following arthroscopic TOE RCR using either a knotless tape bridge (TB) repair or knotted suture bridge (SB) repair technique. We hypothesized that there would be significant improvements in patient-reported outcomes with TOE RCR that would be durable over time. We also hypothesized that the knotless TB technique would yield equivalent clinical results to the knotted SB technique, but that there would be differences in retear types between the two TOE techniques.


Patients included were a minimum of 5 years from an index arthroscopic double-row TOE repair using either a knotless TB or knotted SB technique for one, two, or three tendon full-thickness rotator cuff tears involving the supraspinatus tendon. Preoperative and postoperative American Shoulder and Elbow Surgeons, Short-Form 12 Physical Component Summary, Quick Disabilities of the Arm, Shoulder, and Hand, Single Assessment Numeric Evaluation, and satisfaction scores were collected. Scores were also stratified and compared based on primary and revision repair, tear location, and tear chronicity. Outcomes between techniques were contrasted, and survivorship analysis was conducted, with failure defined as progression to revision surgery.


One-hundred ninety-two shoulders were included with a mean follow-up of 6.6 years (range, 5.0 to 11.0 years). Fifteen shoulders (7.8%) underwent revision cuff repair. All scores improved significantly for TB repair (P < 0.001). For SB repair, all scores improved, but only American Shoulder and Elbow Surgeons and Short-Form 12 Physical Component Summary scores (P < 0.05) demonstrated statistical significance. No statistically significant differences were found between the repair techniques when stratified by primary and revision repairs, tear location, or chronicity. Postoperative clinical survivorship was 96.6% and 93.6% for knotted SB repairs and 96.7% and 93.9% for knotless TB repairs at 2 and 5 years, respectively.


TOE RCR results in significant clinical improvement and excellent survivorship at a minimum of 5 years of follow-up, using either knotted SB or knotless TB repair techniques in primary and revision cases and in small and large tears. Equivalent results were obtained with both TOE techniques. Patients undergoing repair with a TOE showed significant improvements in patient-reported outcomes that were durable at a minimum of 5 years postoperatively.
