摘要:
目的：探讨3D打印技术在膝关节表面置换中的应用。方法：回顾性分析初次行人工膝关节置换术患者43例，根据手术方法不同将患者分为3D打印组（22例）和传统手术组（21例）。观察两组手术情况及隐性出血量、膝关节功能恢复情况和术后满意度。结果：两组患者随访1个月。3D打印组患者手术时间、术中出血量、术后引流量和隐性出血量显著低于传统手术组；两组患者术后2周膝关节活动范围和HSS评分显著高于术前，且下肢力线角度显著小于术前；术后2周3D打印组患者下肢力线角度显著小于传统手术组，而HSS评分显著高于传统手术组；3D打印组总满意度（95.45%）显著高于传统手术组（71.43%），差异有统计学意义（P<0.05）。结论：3D打印技术不仅可以减少人工膝关节置换术出血量及手术时间，还能帮助患者获得良好的下肢力线，改善膝关节功能，提高患者满意程度。
Abstract:
Abstract: Objective To explore the application of 3D printing technology in the surface replacement of the knee joint surface. Methods Forty-three cases of patients who underwent knee arthroplasty for the first time were analyzed retrospectively. According to different surgical procedures, the patients were divided into two groups, namely 3D printing group (n=22) and traditional operation group (n=21). The operation results, the amount of occult bleeding, the recovery of knee joint function and postoperative satisfaction were observed in two groups. Results The patients in both two groups were followed-up for a month. The operation time, intraoperative blood loss, postoperative drainage and occult bleeding in 3D printing group were lower than those in traditional operation group. Two weeks after surgery, the range of motion of knee joint and HSS score were increased, and the angle of lower limb line was decreased in both two groups and compared with traditional surgery group, 3D printing group had a smaller angle of lower limb line and a higher HSS score. The degree of satisfaction of 3D printing group (95.45%) was higher than that of traditional operation group (71.43%), and the difference was statistical significant (P<0.05). Conclusion 3D printing technology can not only reduce intraoperative blood loss and operation time of knee arthroplasty, but also help patients to obtain good lower limb force lines, improve knee joint function and improve degree of satisfaction.
