Substantial bone loss and bone defects are among the most challenging problems faced by surgeons performing revision knee arthroplasty. Tibial bone loss in failed total knee arthroplasty (TKA) is a…
Acetabular bone deficiency may occur primarily (eg, dysplasia, inflammatory arthritis, or seronegative arthropathy) or secondarily (eg, aseptic or septic loosening of acetabular components, osteolysis, trauma, or iatrogenic loss during removal…
Well-fixed femoral and acetabular components often must be removed during revision total hip arthroplasty (THA). Determine which well-fixed components should be removed and which should be left in place at…
The number of revision total knee arthroplasty (TKA) procedures performed is projected to increase at an annual rate of 19.3%.13 Femoral bone defects are uncommon in primary TKA but are…
Extensor mechanism disruption following total knee arthroplasty (TKA) is a devastating complication, with a prevalence of 0.17% to 2.5%.1,3 The patella tendon is involved more commonly (0.22%) than the quadriceps…
Total hip arthroplasty (THA) is successfully performed around the world for the treatment of arthritis, osteonecrosis, and femoral neck fracture, with predictably excellent results. The criteria for successful THA are…
During revision of the femoral component in total knee arthroplasty (TKA), some bone loss from the distal femur is nearly inevitable when the femoral component is removed. Distal femoral bone…
Bone loss and indications for the use of metallic augments in revision total knee arthroplasty (TKA) usually are guided by classification of the bony defect and the intraoperative findings. Probably…
Proximal femur replacement is a salvage limb-sparing surgery for nononcologic and oncologic indications that in the past used to be treated with a major amputation. The magnitude of complexity of…
Valgus osteotomy of the proximal femur can be performed for a number of different conditions including (among others) congenital or acquired coxa vara, fracture nonunion, avascular necrosis (AVN), or Legg-Calvé-Perthes…
