The aim of this study was to compare the clinical and radiologic outcomes of 2 treatment methods for massive and irreparable rotator cuff tears (RCTs): partial repair (PR) and PR with long head of the biceps tendon (LHBT) augmentation. Biceps tendon augmentation is believed to promote better healing at the bone-tendon junction, leading to improved clinical and radiologic outcomes. This retrospective comparative study included patients with chronic, massive and irreparable RCTs involving both the supraspinatus (SSP) and infraspinatus muscles. Only patients with failure of nonoperative treatment and at least 1 year of follow-up between 2013 and 2018 were analyzed. The patients were divided into 2 groups based on the chosen treatment method. Irreparability was defined intraoperatively as the inability to achieve sustainable repair of the SSP after complete release, typically corresponding to a Goutallier classification of stage ≥ 3 and Patte classification of stage 3. The clinical assessment protocol involved measurements of range of motion and shoulder strength, as well as the Constant-Murley score (CMS) and Simple Shoulder Test score. Radiologic assessment comprised measurements of the acromiohumeral distance, Hamada classification, Sugaya classification, and Goutallier classification of both the SSP and infraspinatus. The study included data from 60 patients (30 in each group) with a mean age of 62.5 years and a mean follow-up period of 34.5 months. The retear rate was 43.3% for PR with LHBT augmentation and 73.3% for PR alone (P = .036). During the final examination, statistically significant differences in favor of PR with LHBT augmentation were observed for the CMS (76.2 ± 10.9 vs. 70.9 ± 11.5, P = .034), Sugaya classification (3.5 ± 1.1 vs. 4.1 ± 0.9, P = .035), and acromiohumeral distance (5.8 ± 2 mm vs. 4.7 ± 1.3 mm, P = .021). There were no significant differences between the groups in range of motion, shoulder strength, Hamada classification, Simple Shoulder Test score, and postoperative Goutallier stage. PR with LHBT augmentation for patients with irreparable, massive RCTs provides a lower retear rate and better humeral head centralization, as well as improved results measured by the CMS, compared with PR alone.
