The early term results of 29 cases of revision total knee arthroplasty using highly porous trabecular metal cone implants for femoral and tibial major bone deficit reconstruction (Anderson Orthopedic Research Institute classification type 2B and 3) have been prospectively analyzed. Indications for revision surgery included: aseptic loosening/wear, staged reimplantation after infection, as well as periprosthetic fracture. At an average follow-up of 33 months (range, 13-73 months) the mean Knee Society Score and functional score statistically improved. Radiological follow-up revealed no evidence of loosening or migration of the constructs. No evidence of complications was noted in correlation with the use of trabecular metal cones. This study supports evidence that trabecular metal cones are an efficient and effective option for dealing with significant bone deficits and obtaining stable biological fixation in revision total knee arthroplasty.
对29例采用高度多孔小梁金属锥形植入物进行股骨和胫骨主要骨缺损重建(安德森骨科研究所分类2B型和3型)的翻修全膝关节置换术的早期结果进行了前瞻性分析。翻修手术的指征包括:无菌性松动/磨损、感染后分期再植入以及假体周围骨折。平均随访33个月(范围13 - 73个月),膝关节协会评分和功能评分在统计学上有显著改善。影像学随访未发现植入物松动或移位的迹象。未发现与使用小梁金属锥形植入物相关的并发症。本研究支持小梁金属锥形植入物是处理严重骨缺损和在翻修全膝关节置换术中获得稳定生物固定的有效选择这一证据。
