Abstract:[Objective] To evaluate the risk factors of traumatic arthritis after surgical treatment of tibial plateau fractures. [Methods] The data bases, including Wanfang、SinoMed、CNKI、PubMed、Embase and Cochrane Library were searched for the papers that met the criteria by computer from the creating to October 2022. The risk factors of traumatic arthritis after surgical treatment of tibial plateau frac- tures were analyzed by using RevMan 5.3. [Results] A total of 12 articles were included, including 1 prospective study and 11 retrospective studies, with 338 arthritic patients and 1 038 non-arthritic patients in the study. As results of the meta-analysis, the high-energy injury (OR=3.50, 95%CI 2.44~5.03, P<0.001), fracture type ≥ IV (OR=3.86, 95%CI 2.60~5.73, P<0.001), osteoporosis (OR=2.63, 95%CI 1.04~ 6.65, P=0.04), meniscus injury (OR=1.74, 95%CI 1.08~2.81, P=0.02), time elapsed between injury and surgery >7 days (OR=2.95, 95%CI 2.02~4.30, P<0.001), non-anatomical reduction of the fractures intraoperatively (OR=5.92, 95%CI 2.73~12.84, P<0.001), poor postopera- tive fracture reduction anatomical score (OR=10.67, 95%CI 2.12~53.77, P=0.004), and mechanical axis malalignment ≥ 5° (OR=2.85, 95% CI 1.12~7.26, P=0.03) were risk factors for postoperative traumatic arthritis of tibial plateau fractures. [Conclusion] The high energy injury, tibial plateau fracture type ≥ IV, osteoporosis, meniscus injury, time elapsed between injury and operation >7 days, non-anatomical reduc- tion intraoperatively, poor anatomical score of postoperative fracture reduction, and malalignment of mechanical axis ≥5° are risk factors for traumatic arthritis after tibial plateau fracture surgery. Patients with the above risk factors should be given high attention and early interven- tion to reduce the incidence of postoperative arthritis and improve the clinical prognosis of patients.
