- 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.
