The surgical approach and arthroplasty were the same as those in the mesh group. We made two drillholes (2 cm apart) in the trochanteric crest of the greater trochanter. We passed MB66 nonabsorbable sutures through the drillholes and sutured the capsule and short external rotator tendons together with the modified Kessler method [The posterior capsule and external rotator muscle were repaired by conventional tendon-to-bone method as illustrated (
