Abstract:

Objective To study the efficacy of 3D printing combined with arthroscopic reduction in the treatment of tibial plateau fractures with arthroscopic monitoring. Methods A total of 62 patients with tibial plateau fractures from March 2018 to March 2020 were selected and randomly divided into control group and obser⁃ vation group，31 cases in each group. The control group was treated with arthroscopy，and the observation group was given 3D printing before operation. The operation indicators including mean operation time，intraoperative blood loss，fracture reduction time and clinical indicators including postoperative recovery time，pain and swelling degrees，complications were compared between the two groups. The knee joint function（HSS）and motor function （FMA）scores were compared in the follow⁃up of 6 months. Results There were 28 patients in control group and 29 patients in observation group in all getting the follow⁃up. The mean operation time and fracture reduction time of observation group were shorter than those of control group，and intraoperative blood loss was less（P < 0.05）. The VAS score in 3 days of observation group was lower than that in control group，and the degree of swelling was reduced（P < 0.05）；while there were no differences of recovery time and complication rate between groups（P > 0.05）. Lastly，the HSS and FMA scores of observation group were higher than those of control group after follow⁃up （P < 0.05）. Conclusion 3D printing before operation assisting arthroscopic minimally invasive treatment for tibial plateau fracture has good clinical effect，which can shorten operation and fracture reduction time，reduce blood loss，lighten pain and swelling after operation，and improve knee joint function and motor function.
