Background: To analyze the risk factors of revision operation after the treatment of distal femoral fracture with lateral locking plate (LLP).
Methods: Retrospective analysis of the clinical data of 152 cases with distal femoral fracture treated in our hospital from March 2005 to March 2019. SPSS 26.0 software (univariate analysis and Logistic regression analysis) was used to analyze the general condition, fracture related factors, operation related factors and construct characteristics of internal fixation.
Results: 16 of 152 patients who were included in the study underwent revision surgery, with a revision rate 10.5%. Univariate analysis showed that there were significant differences in age, body mass index(BMI), fracture type, supracondylar involved or not, type of incision, quality of reduction, ratio of length of plate/fracture area(R1), the ratio of the length of the plate/fracture area above the condylar(R2), ratio of distance between proximal part of fracture and screw/working length of proximal plate(R3) between the two groups (P＜0.05). Logistic regression analysis showed that age[OR for age >61.5 group is 4.900(1.071-22.414)], fracture type[OR for A3 fracture is 8.572(1.606-45.750), the OR for periprosthetic fracture after TKA is 9.073(1.220-67.506)], poor reduction quality[OR is 7.663(1.821-32.253)] and the ratio of the length of the plate/fracture area above the condylar were the possible risk factors (P＜0.05).
Conclusion: Age, fracture type (A3 and periprosthetic fracture after TKA), poor reduction quality and the ratio of the length of the plate/fracture area above the condylar were the possible risk factors of the revision in distal femoral fractures treated with lateral locking plate. The appropriate application of the locking plate and operation strategy are the key to reduce the revision rate in distal femoral fractures.
