Hip revision surgery with a cementless tapered femoral component can provide axial and rotational stability in patients with compromised proximal bone stock. This study includes 90 cases revised with the Link MP (Waldemar Link, Hamburg, Germany) prosthesis. The median age at surgery was 72 (38-89) years. Aseptic loosening (70%) and periprosthetic fracture (22%) were common indications for surgery. Sixty-three patients (70%) were followed clinically with a median of 6 (5-11) years of follow-up. All other patients were followed through the Swedish Hip Register. The 5-year survival rate was 98% with stem removal and 90% with any reoperation as the end point. Complications included hip dislocation in 17 (19%) patients. The median Harris hip score was 78 (16-100) points, and the median radiographic stem migration was 2.7 mm at follow-up.
髋关节翻修术采用非骨水泥锥形股骨假体，可为骨量不足的患者提供轴向和旋转稳定性。本研究共纳入 90 例采用 Link MP（德国汉堡 Waldemar Link）假体进行翻修的患者。手术时的中位年龄为 72（38-89）岁。无菌性松动（70%）和假体周围骨折（22%）是常见的手术适应证。63 例患者（70%）接受了临床随访，中位随访时间为 6（5-11）年。所有其他患者均通过瑞典髋关节登记处进行随访。以去除柄和任何翻修为终点，5 年生存率分别为 98%和 90%。并发症包括 17 例（19%）患者髋关节脱位。中位 Harris 髋关节评分 78（16-100）分，随访时的中位放射学假体柄迁移为 2.7mm。
