Tranexamic acid reduces allogenic transfusion in revision hip arthroplasty.
Revision THA is associated with high blood loss and a high probability of blood transfusion in the perioperative period. In November 2003, government legislation established the Blood Utilization Program at our center to reduce the rate and risks associated with allogenic transfusion. ⋯ Level III, therapeutic study. See the guidelines online for a complete description of level of evidence.

Modular femoral stems are one option for revision THA surgeons and allow offset restoration, leg length discrepancy correction, and stability independent of distal stem fixation. The complexity of revision THA usually leads surgeons to use multiple revision hip designs to address these issues. ⋯ Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

THA after acetabular fracture fixation: is frozen section necessary?
Infection is uncommon after THA performed for failed acetabular fracture repair, despite a high reported incidence of culture-positive fixation implants. The use of frozen section analysis at the time of THA after acetabular fracture fixation surgery is unknown. ⋯ Level III, diagnostic study. See Guidelines for Authors for a complete description of levels of evidence.
