Background: Combined lesions of the glenoid labrum involving tears of the anterior, posterior, and superior labrum have been infrequently reported in the literature.
Purpose: To evaluate the clinical outcomes of arthroscopic repair of these lesions in a general population using validated scoring instruments, presence of complications, and need for revision surgery.
Study design: Case series; Level of evidence, 4.
Methods: Fifty-eight patients who had arthroscopic labral repair of tears involving the anterior, posterior, and superior labrum (defined as a panlabral repair) were identified at our institution by retrospective review. All patients underwent arthroscopic labral repair with suture anchor fixation by a uniform approach and with a standardized postoperative protocol. Forty-four patients had a minimum 16-month postoperative follow-up. Outcomes were assessed postoperatively by the American Shoulder and Elbow Surgeons (ASES) score and the Penn Shoulder score. Complications were also documented, including need for revision surgery.
Results: The mean age at the time of surgery was 32 years (range, 15-55 years) in the 44 patients. Presenting shoulder complaints included pain alone (40%), instability alone (14%), or pain and instability (45%). Mean number of anchors per repair was 7.9 (range, 5-12). Mean follow-up was 42 months (range, 16-78 months). Mean ± standard deviation ASES score at final follow-up was 90.1 ± 17.7 (range, 22-100), and mean Penn Shoulder score was 90.2 ± 15.3 (range, 38-100). Three of the 4 patients with outcome scores of 70 or less at final follow-up had undergone prior surgery. Thirteen postoperative complications (30%) occurred, with 3 (7%) requiring a second surgery. Five patients (11%) had an instability event following panlabral repair, but only 1 of these patients (2%) required revision surgery for a recurrent labral tear.
Conclusion: Combined tears of the anterior, posterior, and superior glenoid labrum represent a small but significant portion of labral injuries. Arthroscopic repair of these injuries can be performed with good postoperative outcomes and a low rate of recurrent labral injury.
