Arthroscopic anterior shoulder stabilization with percutaneous assistance and posteroinferior capsular plication.

To study the technique and clinical outcomes of arthroscopic shoulder stabilization with anterior labral repair and percutaneous posteroinferior capsular plication, we retrospectively reviewed 20 cases. Mean (SD) final postoperative follow-up was 3.4 (0.6) years (range, 2.7-5.1 years). A mean (SD) of 4.9 (0.9) suture anchors (range, 4-7) was used during surgery, with 1.6 (0.7) (range, 1-3) devoted to the posteroinferior plication. There were statistically significant improvements in forward elevation (P = .016) and internal rotation (P = .018) from before surgery to final postoperative follow-up; external rotation did not change (P = .336). Significant improvements (P < .001) were also seen in visual analog scale pain ratings, American Shoulder and Elbow Surgeons survey scores, and Simple Shoulder Test scores. Mean (SD) Rowe instability score at final follow-up was 81.1 (28.9). Eighty-five percent of the patients returned to sport at or above preinjury level, and 70% returned to a degree of athletic physical contact at or above preinjury level. Two cases (10%) were categorized as treatment failures (redislocation). Percutaneously assisted arthroscopic anterior stabilization with posteroinferior capsular plication produces acceptable results, with functional outcomes and redislocation rates comparable to those reported in the literature.
