Outcomes Following Double-Row and Medial Double-Pulley Rotator Cuff Repair

Abstract

Multiple arthroscopic double-row repair techniques have been developed to treat full-thickness rotator cuff tears. However, healing rates and functional outcomes vary among these repair methods. A suture tape and medial double-pulley (STDP) technique that incorporated 2-mm suture tape for a knotless double-row with a broad double-mattress suture medially was developed as an alternative method to other double-row repair techniques. This prospective study reviewed the functional outcomes and healing rates of full-thickness supraspinatus tendon tears repaired using an STDP technique. Of 33 consecutive patients who underwent arthroscopic rotator cuff repair with an STDP construct, 24 patients with a minimum of 1 year of follow-up were included in the study. Preoperative fatty atrophy was recorded. Ultrasound imaging was used to assess rotator cuff healing at a minimum of 6 months postoperatively. Range of motion and functional outcome scores were evaluated at final follow-up. Mean active forward elevation improved from 124° preoperatively to 160° postoperatively. Comparing preoperative and postoperative values, the American Shoulder and Elbow Surgeons score improved from 45.9 to 90.8, the Single Assessment Numeric Evaluation score improved from 34.6 to 87.1, and the visual analog scale score decreased from 5.3 to 1.3. Twenty-one of 24 patients (88%) were satisfied with their outcomes. Ultrasound evaluation demonstrated complete healing in 88% of the cohort. The STDP technique is a technically efficient method of obtaining medial fixation in a double-row repair and appears to demonstrate clinically acceptable results. Healing was observed in 88% of cases, and functional outcome showed a statistically significant improvement. [Orthopedics. 2021;44(1):e125-e130.].
