Group A patients chose dual acetabular rotational center and Group B patients chose single acetabular rotational center. The postoperative effects of the two groups 精品文档---下载后可任意编辑of patients were evaluated by observing the operation process and X-ray of the hip joint replacement.Results: The postoperative average hip joint front inclinat...
