Purpose: To evaluate the clinical success rate, along with risk factors for failure, in patients undergoing latissimus dorsi transfer for the treatment of massive, irreparable, previously failed rotator cuff tears., Methods: We performed a retrospective chart review of prospectively collected data from an institutional shoulder outcome registry. All patients who underwent latissimus dorsi transfer for previously failed rotator cuff repair between 2006 and 2013 with a minimum follow-up period of 1 year were included in the study. The indications for inclusion were large (≥2 tendons), retracted, chronic rotator cuff tears with fatty infiltration or atrophy for which prior surgical repair had failed. Preoperative and postoperative American Shoulder and Elbow Surgeons (ASES) and Simple Shoulder Test scores were collected, along with postoperative Single Assessment Numerical Evaluation scores. Complications and clinical failures (Δ in ASES score <17) were recorded. Patient demographic and tear characteristics were evaluated as potential risk factors for failure., Results: A total of 22 patients (mean age, 53 ± 6 years) were included in the study, with a mean follow-up time of 3.4 ± 1.1 years. Over 63% of patients (n = 14) reported undergoing 2 or more prior failed rotator cuff repairs. Patients undergoing latissimus dorsi transfer showed significant improvements in ASES scores (from 35.2 ± 21.9 preoperatively to 55.8 ± 22.9 postoperatively, P = .001), Simple Shoulder Test scores (from 3.5 ± 3.1 preoperatively to 5.2 ± 3.4 postoperatively, P = .002), and pain scores (from 5.9 ± 2.8 preoperatively to 4.6 ± 4.3 postoperatively, P = .002) at final follow-up. The complication rate after latissimus transfer was 27%. The rate of revision to reverse total shoulder arthroplasty was 13.6% (n = 3) after a mean of 2.7 years, and the clinical failure rate was 41% (n = 9) at final follow-up. An acromiohumeral interval of less than 7 mm (P = .04) and high-grade fatty infiltration (grade 3 or greater, P = .004) were significant preoperative risk factors for clinical failure., Conclusions: Latissimus dorsi tendon transfer resulted in a clinical failure rate of 41% and complication rate of 27%, with an acromiohumeral interval of less than 7 mm and high-grade fatty infiltration being associated with postoperative failure., Level of Evidence: Level IV., (Copyright © 2019 Arthroscopy Association of North America.

Purpose: The objective of the current study was to compare surgeon-rated visualization in shoulder arthroscopy using irrigation fluid with and without epinephrine., Methods: Eighty-three patients were randomized to receive irrigation fluid with (44 patients) or without (39 patients) epinephrine during their arthroscopic shoulder procedures. After each procedure, the blinded senior author (G.F.C.) evaluated visualization based on a visual analog scale (VAS), and all clinically important procedure variables were recorded., Results: Eighty-three arthroscopic shoulder procedures were included in the study. Fifty-four of these procedures were arthroscopic rotator cuff repairs, allowing a subset analysis of this specific procedure. There was a significant difference, with improved visualization in the epinephrine group versus the group without epinephrine when comparing all procedures (P < .0001) and when comparing only rotator cuff repairs (P < .0001). However, there was no statistical difference in other clinically important variables, including operative time and amount of irrigation fluid used., Conclusions: The addition of epinephrine to irrigation fluid significantly improves surgeon-rated visualization in shoulder arthroscopy. Without an observed significant difference in operative time or volume of irrigation fluid used, the clinical significance of this improved visualization is unclear, and the use of irrigation fluid without epinephrine remains a viable option in the hands of an experienced surgeon., Level of Evidence: Level I, high-quality randomized controlled trial with statistically significant difference., (Copyright © 2015 Arthroscopy Association of North America.
