Abstract:   Objective  Clinical analysis of the effect of internal fixation combined with postoperative rehabilitation training on tibial plateau fractures.Methods  Fifty patients with tibial plateau fractures were randomly divided into observation group and control group，25 cases in each group.Patients in control group were treated with internal fixation combined with independent rehabilitation.Patients in observation group Internal fixation combined with postoperative rehabilitation training.The knee joint function was assessed by knee function scoring system（HSS）at 3，6，and 12 months after operation.The degree and clinical efficacy of tibial plateau varus（TPA）and rake angle（PA）.Results  Both groups were followed up for 3，6 and 12 months after operation，and the improvement rate of HSS score in observation group was significantly higher than that in control group（P<0.05）;the TPA of the observation group and the control group had a decreasing trend at 3，6 and 12 months after operation，although there was no significant difference between the two groups（P>0.05），but the decrease of the observation group was higher than that of the control group[ the two groups of patients showed an upward trend in PA，the increase in the age group was higher than that in the control group，but the difference was not statistically significant（P>0.05）;the total effective rate in the observation group was significantly higher than that of the control group，the result was statistically significant（P<0.05）.Conclusion  HSS score，TPA，PA were significantly better than traditional open surgery combined with independent rehabilitation treatment after internal fixation operation combined with postoperative rehabilitation training，internal fixation combined with postoperative rehabilitation effective in improving patient's joint function，the prognosis of patients with good.
