Treatment of tibial plateau fractures: A comparison of two different operation strategies with medium-term follow up

BACKGROUND: The objective of this study was to compare the clinical and radiological outcomes of two surgical methods for tibial plateau fractures (TPFs): minimally invasive surgery (MIS) using a double reverse traction repositor and traditional open reduction internal fixation (ORIF). METHODS: From our prospectively collated database, 187 consecutive adult patients with 189 operatively treated TPFs in our level I trauma center were included from January 2015 to March 2018 who had a minimum of three years’ follow-up. All cases were performed by the senior surgeon using either MIS (group 1, 84 patients with 84 TPFs) or ORIF (group 2, 103 patients with 105 TPFs). Details of the demographics, injury mechanism, pre- and postoperative follow-up imaging, operative procedures and complications were collected. The final results from the 36-Item Short-Form Health Survey (SF-36), Western Ontario and McMaster Universities Osteoarthritis index (WOMAC) and Hospital for Special Surgery (HSS) were obtained at the final follow-up. RESULTS: Clinically, significant differences were observed in the WOMAC (pain, P ​= ​0.001; stiffness, P ​< ​0.001), HSS (P ​= ​0.003) and SF-36 (P ​= ​0.001). Radiologically, significant intergroup differences were observed in the loss of immediate postoperative reduction rates, secondary loss of reduction rates and signs of osteoarthritis (Kellgren–Lawrence). Two and ten superficial infections in group 1 (2.4%) and group 2 (9.5%), respectively, and 6 lateral popliteal nerve palsy cases occurred (0 MIS, 6 ORIF), with significant intergroup differences. CONCLUSION: Our study shows that the MIS using a double reverse traction repositor is promising and safe technique for the TPFs when used for the correct indications. THE TRANSLATIONAL POTENTIAL OF THIS ARTICLE: The current status of using a minimally invasive surgery for the treatment of TPFs have been analyzed and a new method of using a double reverse traction repositor for the treatment of TPFs have been proposed in this study, which updated treatment concept of TPFs.
