Case Discussion

Periprosthetic fractures involving the distal femur are increasing in prevalence (most likely down to an ageing population) they occur after trivial trauma such as the case above 1. Supracondylar periprosthetic femoral fractures are generally classified via the Rorabeck and Taylor system where 2.3:
