(1) : The aim of this study was to evaluate short- to mid-term clinical and radiological results in patients undergoing primary total hip arthroplasty (THA) with the use of a Selective Laser Melting 3D-printed highly porous titanium acetabular cup (Jump System Traser, Permedica Orthopaedics). (2) : We conducted a retrospective study and collected prospective data on 125 consecutive patients who underwent primary THA with the use of highly porous titanium cup. Each patient was evaluated preoperatively and postoperatively with a clinical and radiological assessment. (3) : The final cohort consisted of 104 patients evaluated after a correct value of 52 (38-74) months. The median Harris Hip Score (HHS) significantly improved from 63.7 (16-95.8) preoperatively to 94.8 (38.2-95.8) postoperatively ( < 0.001), with higher improvement associated with higher age at surgery (β = 0.22, = 0.025). On postoperative radiographs, the average acetabular cup inclination and anteversion were 46° (30°-57°) and 15° (1°-32°), respectively. All cups radiographically showed signs of osseointegration with no radiolucency observed, or component loosening. (4) : The use of this highly porous acetabular cup in primary THA achieved excellent clinical, functional, and radiological results at mid-term follow-up. A better clinical recovery can be expected in older patients. The radiological evaluation showed excellent osseointegration of the cup with complete absence of periprosthetic radiolucent lines.
(1)：本研究的目的是评估使用选择性激光熔化3D打印的高度多孔钛髋臼杯（Jump System Traser，Permedica Orthopaedics）进行初次全髋关节置换术（THA）患者的短期至中期临床和放射学结果。(2)：我们进行了一项回顾性研究，并收集了125例连续使用高度多孔钛杯进行初次THA患者的前瞻性数据。每位患者在术前和术后均接受临床和放射学评估。(3)：最终队列由104例患者组成，在平均52（38 - 74）个月的随访后进行评估。Harris髋关节评分（HHS）中位数从术前的63.7（16 - 95.8）显著提高到术后的94.8（38.2 - 95.8）（<0.001），手术年龄越大改善越明显（β = 0.22，P = 0.025）。术后X线片显示，髋臼杯平均倾斜度和前倾角分别为46°（30° - 57°）和15°（1° - 32°）。所有髋臼杯在X线片上均显示骨整合迹象，未观察到透光线或假体松动。(4)：在初次THA中使用这种高度多孔髋臼杯在中期随访时取得了优异的临床、功能和放射学结果。老年患者有望获得更好的临床恢复。放射学评估显示髋臼杯骨整合良好，假体周围完全没有透光线。
