UNLABELLED
Tibial bone loss is a common scenario encountered during revision total knee arthroplasty. Reconstructive options depend on the amount and location of bone loss, but few good solutions exist to address large, uncontained tibial defects where cortical support is lost in the metadiaphyseal region. We describe a novel technique using acetabular augments to buttress a revision tibial component and recreate a hemiplateau during tibial revision total knee arthroplasty. In selected scenarios, this construct can create a biomechanically friendlier surface onto which to support the tibial tray and a less expensive option when compared to traditional stacked augments or cones.

胫骨骨缺损是翻修全膝关节置换术中常见的情况。重建方案取决于骨缺损的量和位置，但对于干骺端区域皮质骨支撑缺失的大面积、非包容性胫骨缺损，几乎没有好的解决方案。我们描述了一种新技术，在胫骨翻修全膝关节置换术中，使用髋臼增强器支撑翻修胫骨组件并重建半平台。在特定情况下，与传统的堆叠增强器或锥体相比，这种结构可以创建一个生物力学上更友好的表面来支撑胫骨托，并且成本更低。
