Distal femoral replacement following periprosthetic fractures around the Stanmore total knee

Distal femoral periprosthetic fractures associated with total knee replacement occur more commonly in patients with osteopenia and rheumatoid arthritis. This compromises the results of either conservative treatment or internal fixation. We describe a technique in which the distal femur together with the femoral component are removed and replaced with a custom made endoprosthesis which articulates with the tibial component which remains in situ. The surgery is quick and simple with good short term results.
