Evaluation of long-term postoperative outcomes between mini-open and arthroscopic repair for isolated supraspinatus tears: a retrospective analysis.

BACKGROUND: Despite arthroscopic repair of the rotator cuff is an increasingly popular procedure, the mini-open (MO) repair still remains a viable and appreciated technique. The purpose of the study was to analyze the long-term clinical outcomes of patients with isolated supraspinatus tear undergoing MO or arthroscopic surgery (AS) repair.

PATIENTS AND METHODS: Forty-six patients underwent supraspinatus repair with anchors: 24 with MO technique and 22 with AS procedure. They were evaluated postoperatively at 3, 6, 12 months and 2 years.

RESULTS: The mean surgery time, the mean hospital stay and the average costs were shorter in the MO patients respect to the AS group. Despite an initial better Disabilities of Arm, Shoulder and Hand and Constant Murley Score in the first 6 months of follow-up in the AS group, no differences were detected at 24 months.

CONCLUSION: This study suggests that isolated supraspinatus tears can be treated with a MO or arthroscopic repair procedure with similar clinical outcome in the long-term postoperative period. The mean surgery time and the average costs are less in the MO group respect to the AS group.
