These complex revisions involve severe femoral bone loss (secondary to osteolysis with extension to the femoral shaft) or femoral shaft fractures that could not be adequately treated by a conventional cemented or cementless stem.
This selection would exclude the majority of revisions with severe bone defects.
This article provides a review of contemporary methods of bone loss management with a focus on highly porous metals and an emphasis on the authors' preferred method for managing the severe bone loss in revision TKA.
Moreover, intense research efforts have been directed at characterising postoperative thigh pain, a clinical limitation in THA that can range from immediate mild postoperative symptoms to severe disabling pain requiring revision surgery [ 7, 8].
