To evaluate the clinical outcome and the osseous union of strut onlay allografts (SOAs) used as adjunct in revision total joint arthroplasty (TJA).
Patients that had previously undergone SOA augmentation were considered for inclusion. Patients were invited to provide information for the following: Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), EuroQol five dimension score (EQ-5D) and Parker mobility score. Osseous union rates between SOA and the host bone were determined by radiograph with the Emerson classification system. Bone mineral density was measured via quantitative computed tomography.
Seventeen patients were identified, at a mean follow-up of 2.8 years. The median total WOMAC score was 22 [interquartile range (IQR)=21]. The median EQ-5D score was 0.887 (IQR=0.350) (time trade-off). The Parker Mobility Score was 8.0 (IQR=3.5). Emerson stages of radiographic graft to host union were 'rounding off' in one case, 'partial bridging' in three and 'complete bridging' in 13. Quantitative computed tomography showed an average bone mineral density of approximately 1,300 mg/cm3.
From our findings, it is concluded that SOAs used in revision total joint arthroplasty provide promising results and are recommended for broader clinical use. A complete osseous union between host and graft bone was observed in the majority of cases.
评估支撑式同种异体骨移植（SOA）作为翻修全关节置换术（TJA）辅助手段的临床效果和骨愈合情况。
考虑纳入先前接受过 SOA 增强的患者。邀请患者提供以下信息：西安大略和麦克马斯特大学骨关节炎指数（WOMAC）、欧洲五维健康量表（EQ-5D）和帕克活动能力评分。通过放射照相和 Emerson 分类系统确定 SOA 与宿主骨之间的骨愈合率。通过定量计算机断层扫描测量骨密度。
确定了 17 名患者，平均随访 2.8 年。WOMAC 总分中位数为 22 [四分位距（IQR）=21]。EQ-5D 评分中位数为 0.887（IQR=0.350）（时间权衡）。帕克活动能力评分为 8.0（IQR=3.5）。放射照相移植骨与宿主骨融合的 Emerson 分期为 1 例“变圆”，3 例“部分桥接”，13 例“完全桥接”。定量计算机断层扫描显示平均骨密度约为 1300 mg/cm3。
根据我们的发现，SOA 用于翻修全关节置换术可提供有前景的结果，建议更广泛地临床应用。在大多数情况下，宿主骨和移植物骨之间观察到完全的骨愈合。
