The aim of this study was to evaluate the clinical and radiographic results of cementless acetabular revision with deep frozen morsellised allografts. Sixty-one patients (65 hips) underwent acetabular revision using cementless components and deep frozen morsellised allografts. Fifty-seven hips (53 patients) were reviewed at a mean of 105.1 months (range 72-180 months) after revision. The study group included 29 males and 24 females with a mean age of 46.4 years. One cup underwent further revision for aseptic loosening and two were defined as radiographic failures. The mean time for allograft incorporation was 12.5 months (range 6-24 months) after index surgery. The mean Harris hip score of the patients improved from 61.1 points preoperatively to 91.6 points postoperatively. Linear and cavitary osteolysis was observed in two and 12 hips, respectively. The acetabular revision using cementless components with deep frozen morsellized allografts provides favourable clinical and radiographic results, although the initial disease and age may adversely affect the outcomes.
本研究旨在评估非骨水泥髋臼翻修中使用深冻碎骨移植物的临床和影像学结果。61 例患者（65 髋）接受了非骨水泥髋臼翻修术，并使用深冻碎骨移植物。57 髋（53 例患者）在翻修后平均 105.1 个月（72-180 个月）时进行了回顾。研究组包括 29 名男性和 24 名女性，平均年龄为 46.4 岁。1 个髋臼因无菌性松动而再次翻修，2 个髋臼被定义为影像学失败。所有移植物的平均融合时间为索引手术后 12.5 个月（6-24 个月）。患者的平均 Harris 髋关节评分从术前的 61.1 分提高到术后的 91.6 分。线性和囊性溶骨分别在 2 髋和 12 髋中观察到。使用非骨水泥髋臼组件和深冻碎骨移植物进行髋臼翻修可获得良好的临床和影像学结果，但初始疾病和年龄可能对结果产生不利影响。
