ABSTRACT
Background: Periprosthetic fractures following total knee arthroplasty (TKA) are infrequent, devastating complications. The purpose of study is to compare non operative and open reduction and internal fixation techniques for periprosthetic supracondylar femur fractures.
Methods: We followed 3920 patients of TKR and found 23 patients having periprosthetic fractures. 20 patients were treated by operative method while 3 patients were treated by conservative methods.
Results: The total incidence of the fracture was 0.58 %. 3 patients suffered from infection after surgery. 2 out of 3 conservative treated cases had malunion, while amongst 20 cases treated operatively, 16 had primary union, 2 had union after bone grafting while 2 had non union. The average reduction in the knee score after fracture is 20.53%.
Conclusions: Good results for periprosthetic fracture can be obtained if proper and timely intervention is done. However, short duration of follow up and small number of patients is major limiting factor.
