阶梯式多孔钛干骺端套筒可以提供增强固定的选择，以处理翻修全膝关节置换术 (TKA) 中具有挑战性的胫骨缺损。我们回顾性分析了 2007 年 6 月至 2011 年 7 月期间 51 名因安德森骨科研究所 (AORI) II 型和 III 型胫骨缺损接受干骺端套筒翻修术的患者的数据。在这 51 名患者中，36 名患者拥有完整的临床和影像学数据。在最后一次随访（平均：38 个月）中，术后观察到膝关节活动度和膝关节协会评分显着改善（P < 0.001）。需要进行四次修正手术，但没有一次是因为无菌种植体固定失败。最终随访时的放射线检查显示稳定的骨整合成分，没有成分迁移或临床上显着的骨溶解。干骺端套筒用于治疗全膝关节置换术中中度至重度胫骨缺损，取得了满意的临床结果，是实现稳定固定的多功能选择。 (C) 2014 Elsevier Inc. 保留所有权利。
Stepped porous titanium metaphyseal sleeves may provide an option for enhanced fixation in managing challenging tibial defects in revision total knee arthroplasty (TKA). We retrospectively reviewed data on 51 patients who underwent revision TKA utilizing a metaphyseal sleeve for Anderson Orthopaedic Research Institute (AORI) Type II and III tibial defects between June 2007 and July 2011. Of these 51 patients, 36 patients had complete clinical and radiographic data. At final follow-up (mean: 38 months) significant improvements in knee range of motion and Knee Society scores were observed postoperatively (P < 0.001). Four revision procedures were necessary, but none for aseptic implant fixation failure. Radiographic review at final follow-up revealed stable, osteointegrated components without component migration or clinically significant osteolysis. Metaphyseal sleeve use in the management of moderate to severe tibial defects in revision TKA resulted in satisfactory clinical outcomes and is a versatile option for achieving stable fixation.
