The exclusion criteria consisted of less than 2\u00a0years' follow\u2010up, previous hip surgery, inflammatory arthritis, open surgery, full\u2010thickness abductor tear, and Workers' Compensation patients. All patients underwent a documented preoperative physical examination with strength testing (scale of 0\u20105) and observation of their gait. Patient satisfaction and PRO scores were recorded preoperatively; at 3\u00a0months postoperatively; and at 1, 2, 5, and 10\u00a0years after surgery. The PRO scores collected were the modified Harris Hip Score, Hip Outcome Score\u2013Activities of Daily Living Subscale, Hip Outcome Score\u2013Sports\u2010Specific Subscale, Non\u2010arthritis Hip Score, and VAS score.
