Abstract：BACKGROUND:As more and more studies focus on the distal femoral fractures, the treatment has transformed from conventional conservative treatment to positive surgical treatment. At present, there are a variety of internal fixation methods in treatment of distal femoral fractures, but the prognosis is rarely reported. <br> OBJECTIVE:To explore and compare the effect of LISS plate and condylar plate fixation on the prognosis and rehabilitation of patients with distal femoral fractures, and provide evidence for the choice of internal fixation. <br> METHODS:Seventy-eight patients with distal femoral fractures were recruited from March 2009 to January 2013 and were randomly divided into two groups, with 39 cases in each group. The two groups were treated with internal fixation using LISS plate and condylar plate, respectively. The intraoperative and postoperative indicators of patients in the two groups were recorded. Evanich score at 12 months after discharge and adverse events during the folow-up were also observed. <br> RESULTS AND CONCLUSION:The incision length and fracture healing time in the LISS plate group were shorter than the condylar plate group (P < 0.05). At 12 months after discharge, there was no statisticaly significant difference in pain scores and stability between the two groups (P> 0.05); while the range of motion, scores of quadriceps femoris strength and Evanich total scores in the LISS plate group were higher than the condylar plate group (P < 0.05), the subtraction project was less than the condylar plate group (P < 0.05). The incidence of adverse events during the folow-up period was 5% (2/39) in the LISS plate group and 20.5% (8/39) in the condylar plate group, the difference was statisticaly significant between the two groups (P < 0.05). LISS plate internal fixation is better than condylar plate fixation for treatment of distal femoral fractures, it can effectively promote fracture healing and functional recovery of knee joint, induce fewer complications, and is an ideal method of internal fixation in field of orthopedics.
