(a) Preoperative radiograph of a 54-year-old woman with Crowe type II dysplasia. (b) On a postoperative radiograph, the cup center-edge angle was −9.2° and the bone coverage index was 48.8%. A morselized autograft was used. (c) A radiograph taken 3 years after surgery showed fixation by bone ingrowth with no radiolucent lines. The allograft was perfectly incorporated into the host bone.
