Abstract：
Accurate pre-operative templating of prosthesis components is an essential factor in successful total hip arthroplasty (THA), including robotically-assisted THA (RA-THA) techniques. We sought to validate the accuracy of a novel, robotic-optimized THA planning software compared to a predicate THA planner for component sizing. We analyzed a series of 199 patients who received manual THA (mTHA) and fluoroscopy-based RA-THA at a single institution. All cases were templated using a predicate pre-operative templating software. For RA-THA cases, the novel robotic-optimized pre-operative planner software was also used for templating. The differences between templated and implanted acetabular cup, femoral head, and stem component sizes were compared based on matching within 1, 2, and ≥3 sizes. Differences in templated and implanted femoral stem implant geometry were also compared. The robot-optimized pre-operative RA-THA plans demonstrated equivalent accuracy to that of predicate pre-operative plans for both RA-THA and mTHA cases. Templated acetabular cups (90.4 vs. 86.8 vs. 82.8; p = 0.421), femoral stems (76.0 vs. 65.1 vs. 67.7; p = 0.096), and femoral heads (91.3 vs. 96.2 vs. 88.2; p = 0.302) were within +/-1 size of implanted components. No significant differences were detected in the proportion of matching templated and implanted stem geometry across the study cohorts.
摘要：
准确的假体组件的术前模板是成功的全髋关节置换术（THA）的一个重要因素，包括机器人辅助THA(RA-THA)技术。我们试图验证小说的准确性，与用于组件大小调整的谓词THA计划器相比，机器人优化的THA计划软件。我们分析了199例患者，这些患者在一个机构接受了手动THA（mTHA）和基于透视的RA-THA。所有病例均使用谓词术前模板软件进行模板化。对于RA-THA病例，新颖的机器人优化的术前计划软件也用于模板。模板化和植入髋臼杯之间的差异，股骨头,和茎组件尺寸根据1、2和≥3尺寸内的匹配进行比较。还比较了模板化和植入的股骨柄植入物几何形状的差异。机器人优化的术前RA-THA计划显示出与RA-THA和mTHA病例的预测术前计划相当的准确性。模板化髋臼杯（90.4vs.86.8vs.82.8；p=0.421），股骨茎（76.0vs.65.1vs.67.7；p=0.096），和股骨头（91.3vs.96.2vs.88.2；p=0.302）在植入组件的+/-1尺寸内。在整个研究队列中，模板化和植入的茎几何形状的匹配比例没有检测到显着差异。
