Fatigue fractures of total knee prostheses - a cause of knee pain.

Femoral component fracture is a rarely reported complication in cemented total knee arthroplasty. We present a case of new- onset acute unresolving knee pain caused by fatigue fracture of the medial condyle of the femoral component 11 years after primary total knee replacement. This was identified and subsequently revised with a revision prosthesis.

The routine use of tranexamic acid in hip and knee replacements.

Purpose: Our aim was to determine whether the administration of intravenous tranexamic acid is a safe and effective means of reducing blood loss associated with hip and knee replacement surgery.

Method: Sequential cohort study analysing hemoglobin titers, transfusion rates, and the occurrence of venous thromboembolism in patients undergoing hip and knee replacements with and without the administration of tranexamic acid at the time of induction. Finally, a cost benefit analysis was performed.
