A meta-analysis of the efficacy of three-dimensional printing-assisted surgery for tibial plateau fractures / 中国组织工程研究

ABSTRACT

BACKGROUND:Three-dimensional (3D) printing technology exhibits a broad future in the orthopedics,especially exhibiting good guidance and auxiliary in the treatment of tibial plateau fractures.However,the related researches are few,and there is a lack of evidence-based medicine to confirm its application values.OBJECTIVE:To compare the efficacy of 3D printing-assisted surgery and traditional surgery in the treatment of tibial plateau fractures through a meta-analysis.ME=THODS:MEDLINE,Cochrane library,Embase,CBM,CNKI and WanFang databases were searched by computer and the relevant literatures were retrieved manually,to collect the controlled trials concerning the efficacy of 3D printing-assisted surgery versus traditional surgery for tibial plateau fractures.Methodology quality of the trials was assessed critically and relative data were extracted,followed by analysis on Stata 11.0 (Stata Corporation,College Station,TX) software.RESULTS AND CONCLUSION:(1) Seven controlled trials involving 362 patients were included.(2) Meta-analysis results showed that the 3D printing-assisted surgery had shorter operation time (SMD=-2.411,95％C/=-2.718-2.104,P=-0.00) and less intraoperative blood loss (SMD=-1.579,95％C/=-1.842--1.316,P=-0.00) than those in the traditional surgery.The excellent and good rate in Rasmussen and Hospital for Special Surgery knee scores showed no significant differences between two growps (P ＞ 0.05).(3) To conclude,compared with the traditional surgery,the 3D printing-assisted surgery can significantly shorten the operation time and reduce the intraoperative blood loss in the treatment of tibial plateau fractures.
