Porous-coated metaphyseal sleeves are designed to fill bone loss and facilitate osseo-integration when bone loss occurs during revision total knee arthroplasty (TKA). The purpose of this paper was to evaluate the clinical and radiographic outcomes of porous-coated metaphyseal sleeves for severe bone loss in revision TKA.
Form December 2014 to March 2018, we retrospectively analyzed 36 patients receiving revision TKAs. They had Anderson Orthopaedic Research Institute (AORI) Type II and III tibial bone loss and were treated with metaphyseal sleeve. The patients were followed up for a mean time of 28.5 months. The Knee Society Score (KSS), the Hospital for Special Surgery (HSS) Knee Score, Visual Analog Scale (VAS) score and the range of motion (ROM), radiographic findings of sleeve osteo-integration were also recorded. The paired t test was used to compare the KSS, the HSS knee score and VAS score before and after the revision TKAs. A value of P < 0.05 was considered statistically significant.
Thirty-six patients had complete clinical and radiographic data. At the final follow-up (mean: 28.5 months), significant improvements in knee range of motion, KSS, HSS score and VAS score were observed postoperatively (P < 0.001 for all). No aseptic implant fixation failure occurred. Radiographic reviews at the final follow-up revealed that components were stable without occurrence of component migration or clinically significant osteolysis.
This short-term retrospective study illustrated that porous-coated metaphyseal sleeves were useful in revision TKA, with a low rate of intraoperative complications, excellent osteo-integration and stable fixation.
多孔涂层干骺端套筒旨在在翻修全膝关节置换术（TKA）期间发生骨质流失时填充骨质缺损并促进骨整合。本文的目的是评估多孔涂层干骺端套筒用于翻修TKA中严重骨质流失的临床和影像学结果。
从2014年12月至2018年3月，我们回顾性分析了36例行翻修TKA的患者。他们患有安德森骨科研究所（AORI）II型和III型胫骨骨质流失，并接受了干骺端套筒治疗。患者平均随访28.5个月。还记录了膝关节协会评分（KSS）、特种外科医院（HSS）膝关节评分、视觉模拟量表（VAS）评分和活动范围（ROM），以及套筒骨整合的影像学表现。采用配对t检验比较翻修TKA前后的KSS、HSS膝关节评分和VAS评分。P < 0.05被认为具有统计学意义。
36例患者有完整的临床和影像学数据。在最后一次随访时（平均：28.5个月），术后膝关节活动范围、KSS、HSS评分和VAS评分均有显著改善（所有P < 0.001）。未发生无菌性植入物固定失败。最后一次随访时的影像学检查显示组件稳定，未发生组件移位或临床上显著骨溶解。
这项短期回顾性研究表明，多孔涂层干骺端套筒在翻修TKA中有用，术中并发症发生率低，骨整合良好且固定稳定。
