Purpose: To analyze minimum 2-year postoperative patient-reported outcomes of a large group of patients after arthroscopic subscapularis (SSc) repair with respect to surgical findings and concurrent procedures. Methods: Patients who underwent arthroscopic SSc repair from January 2010 to April 2016 completed the Patient-Reported Outcomes Measurement Information System for Upper Extremity (PROMIS-UE) test and postoperative visual analog scale pain score. Medical records were reviewed for the preoperative visual analog scale pain score and surgical findings. SSc tears were considered partial or complete. Concomitant pathology and treatment of the supraspinatus (SS), infraspinatus (IS), and biceps tendon were recorded. We compared preoperative variables and outcomes between isolated partial SSc repair, partial SSc with SS and/or IS repair, isolated complete SSc repair, and complete SSc with SS and/or IS repair. Results: One hundred forty-five shoulders were included with an average age of 62.0 ± 9.8 years and average follow-up period of 52.2 ± 19.5 months. A significant reduction in the pain score occurred, from 4.8 (95% confidence interval [CI], 4.4-5.2) to 0.9 (95% CI, 0.6-1.1) (P < .001), with a mean postoperative PROMIS-UE score of 50.7 (95% CI, 49.5-52.0). Most SSc tears were partial with SS and/or IS repair (44.1%). Isolated partial SSc tears (29.9%), complete SSc tears with SS and/or IS repair (20.1%), and isolated complete SSc tears (5.9%) were less common. A significant difference in the mean postoperative PROMIS-UE score was not found between groups (P = .609). Biceps tendon pathology was significantly more common in complete SSc tears than partial SSc tears (P < .001), but there was no difference in the rate of biceps intervention (P = .110) or the PROMIS-UE score based on biceps intervention (P = .471). Conclusions: We observed significant improvements in pain and patient-reported outcomes in line with population means for a large group of patients after SSc tendon repair. Importantly, outcomes were similar despite the size of SSc tear or concurrent SS and/or IS repairs. Biceps pathology was common, and neither its presence nor its treatment influenced postoperative patient outcomes. Level of Evidence: Level IV, retrospective case series.
