Radiographic changes occurring beneath three types of non-cemented, porous coated, cobalt-chrome tibial components were retrospectively reviewed a minimum of 1 year after arthroplasty. Radiolucent zones, radiodense lines, and loose sintered particles were commonly observed. These changes are consistent with non-rigid, fibrous tissue fixation. Histologic evaluation of two specimens retrieved at revision surgery revealed predominantly fibrous tissue within the porous surface under the tibial plateau. The long-term implication of fibrous tissue fixation of porous coated tibial implants in unknown.
对三种非骨水泥型、多孔涂层钴铬合金胫骨部件植入后至少1年的影像学变化进行了回顾性研究。常见透亮区、致密线和松散的烧结颗粒。这些变化与非刚性纤维组织固定一致。翻修手术取出的两个标本的组织学评估显示，胫骨平台下方多孔表面主要为纤维组织。多孔涂层胫骨植入物纤维组织固定的长期影响尚不清楚。
