A 68-year-old woman underwent arthroscopic capsular release and manipulation under general anesthesia for adhesive capsulitis. Six hours postoperatively, she suffered an anterior glenohumeral joint dislocation with passive forward flexion while working with physical therapy. Postoperative workup revealed pseudocholinesterase deficiency. Pseudocholinesterase deficiency may increase the risk of atraumatic glenohumeral dislocation in the immediate postoperative period. Caution should be taken concerning early physical therapy in these patients to minimize the risk of dislocation.
