Arthroscopic stabilization in patients with glenoid bone erosion yielded satisfactory outcomes

Young patients with glenoid bone erosions of more than 20% and who underwent arthroscopic stabilization procedures for recurrent anterior shoulder instability experienced satisfactory clinical outcomes and recurrence rates, according to results. However, researchers noted these results were inferior when compared to patients with glenoid erosions of less than 20%.
Researchers categorized 161 patients who underwent an arthroscopic stabilization procedure for recurrent anterior shoulder instability with anterior glenoid bone erosions and had at least 2 years follow-up into either a 20% erosion group (group 1; n=32) or a less than 20% erosion group (group 2; n=129). Researchers compared clinical outcomes between the groups using the American Shoulder and Elbow Surgeons score, Rowe score and sports/recreation activity level, and documented postoperative complications, including instability recurrence.
Results showed approximate mean glenoid defect sizes of 22.1% and 12.2% in group 1 and group 2, respectively. Although researchers found significantly improved clinical outcomes in group 1 postoperatively, these results were inferior to the clinical outcomes in group 2. According to results, 15.6% of patients in group 1 experienced postoperative recurrences vs. 5.4% of patients in group 2. Researchers noted 84.4% of patients in group 1 achieved competent recoveries to sports/recreative activity.
“Arthroscopic stabilization procedures can be applied as the primary treatment of recurrent anterior shoulder instability with a large glenoid bone erosion for functional restoration and return to previous sports activity level,” the authors wrote. – by Casey Tingle
