The purpose of this study is to report outcomes of an arthroscopic knotless double-row (DR) rotator cuff repair (RCR) technique at 2- and 5- years postoperatively, and to compare clinical outcomes in patients undergoing knotless DR RCR with incorporated lateral row biceps tenodesis (LRT) vs. those without LRT. All primary RCR surgeries were performed by a single surgeon at a single institution using a knotless transosseous equivalent (TOE) technique. The postoperative rehabilitation protocol was standardized for all patients. The primary outcomes collected included American Shoulder and Elbow Surgeons (ASES) Function, ASES Index, Single Assessment Numeric Evaluation (SANE), Simple Shoulder Test (SST), Veterans RAND 12-Item Health Survey (VR-12) physical and mental, and Visual Analogue Scale (VAS) scores. Three hundred forty-two patients met inclusion criteria, of which 262 patients underwent isolated RCR and 61 underwent RCR with a concomitant LRT, 15 underwent RCR with concomitant tenotomy and 4 had RCR with débridement of the biceps. Significant improvements in VAS, ASES, SANE, SST, and VR-12 scores were observed at all-time points in all patient groups. No statistically significant differences in outcomes were noted in patients undergoing RCR with a lateral row tenodesis vs. those undergoing RCR alone. Similarly, no differences were seen when stratified by age, sex, body mass index, Worker’s Compensation status, smoking, and diabetes mellitus. Based on ASES, 81% of patients met minimum clinically important difference, and 64% met maximal outcome improvement at 1-year postoperatively. Knotless DR TOE arthroscopic RCR significantly improves patient-reported clinical outcomes at 1-, 2- and 5-year follow-ups. These results are reflected in clinical practice because 80% achieve minimum clinically important difference postoperatively. Patient-related factors, including body mass index, age, sex, Worker’s Compensation, and diabetes mellitus do not significantly affect patient-reported outcomes in the first 5 years after surgery. Smokers have worse baseline scores which persist at 2-year follow-up. Lastly, adding an arthroscopic LRT in knotless DR TOE arthroscopic RCR provides similar clinical outcomes to knotless DR TOE arthroscopic RCR without biceps tenodesis.
