Abstract Objective To analysis the outcome of total knee replacement in elderly patients with distal femoral fracture in order to determine whether total knee replacement can be an available method.Methods In this study，17 patients aged from 66 to 87 years old (mean age as 80.2 years) with the KL arthritis grade of two or over.They were treated with total knee arthroplasty，the choice of the implant and level of constraint was determined as bone defects and ligaments status.Patients were allowed rapid mobilisation with immediate full weightbearing，then they were followed up for clinically and radiographically.Results Mean blood loss was 789 mL (660～1 860 mL)，mean operative time was 78 minutes (57～118 mins).There were no peri-operative deaths.Patients were followed up from 0.75 to 4.00 years (mean 2.4 years).The patients returned to independent walking meanly in 6 days(3～17 day).At the latest follow-up，there was no dislocation or loosening，no secondary operation，Mean ROM was 95.3° (78.4°～112.3°)，and mean HSS score was 83.6 (74～92).Conclusion Total knee replacement is a reasonable treatment of distal femoral fractures in elderly.
