Abstract Objective To investigate the effect of locking plate surgery via the Carlson posterolateral approach on posterolateral tibial plateau fracture and its effect on joint function. Methods A total of 60 patients with posterolateral tibial plateau fracture admitted to the Anhui Wanbei Coal and Power Group General Hospital from January 2017 to January 2020 were selected and they were divided into observation group and control group according to random number table method, with 30 cases in each group. The observation group received locking plate surgery via the Carlson posterolateral approach, while the control group received locking plate surgery via the traditional posterior median approach. Intraoperative blood loss, fracture exposure time, surgery time, healing time, time to full weight bearing, incidence of complications and Rasmussen score of knee function six months after surgery were compared between the two groups. The changes of posterior slope angle (PA) and tibial plateau angle (TPA) of knee joint were compared between the two groups immediately after surgery and six months after surgery. Results The amount of intraoperative blood loss in the observation group was significantly less than that in the control group, and the fracture exposure time was significantly shorter than that in the control group, and the differences were statistically significant (all P < 0.05). There were no significant differences in surgery time, healing time and time to full weight bearing between the two groups (P ＞ 0.05). After surgery, there were no complications such as foreign body rejection and incision nonunion in the two groups. The excellent and good rate of Rasmussen score in observation group was significantly higher than that in control group, and the difference was statistically significant (P < 0.05). There were no significant differences in PA and TPA between the two groups immediately after surgery and six months after surgery (P ＞ 0.05). Conclusion Locking plate surgery via the Carlson posterolateral approach can reduce intraoperative blood loss in patients with posterolateral tibial plateau fracture, shorten fracture exposure time, and significantly restore the knee function of patients, which is worthy of clinical promotion and application.
