A new technique of arthroscopic fixation using double anchors for SLAP lesions

The aim of this study was to evaluate the clinical and structural outcome of the new fixation technique of type-II SLAP repair using double anchors compared with conventional method.

Twenty-eight patients with 29 shoulders, who were followed up for at least 1 year after surgery, were enrolled. Fourteen shoulders were treated using the new technique (group 1), and 15 shoulders using the conventional technique (group 2). The clinical outcomes were evaluated using two different functional scores, the pain VAS and range of motion. The postoperative labral integrity was determined by magnetic resonance imaging at 1 year after surgery.

At postoperative 6 months, all functional scores of group 1 were superior to group 2, particularly in pain VAS and Constant Scoring System. All ranges of motion in group 1 showed a better result than in group 2, particularly in forward flexion and external rotation at 90° abduction (88° ± 4.8 in group 1 and 84° ± 9.2 in group 2, P = 0.03). At postoperative 12 months and the last visit, all functional scores in group 1 were superior to those in group 2 and all external rotations at 90° of abduction in group 1 showed significantly better results than those of group 2. All patients in group 1 showed complete healing of the repaired SLAP lesion but one patient in group 2 showed partial detachments on the MRI.

This new technique provides anatomical restoration of a SLAP lesion and yields successful clinical and structural outcomes at a short-term follow-up.
