Tranexamic acid reduces blood loss in cemented hip arthroplasty: a randomized, double-blind study of 39 patients with osteoarthritis.

Background: Tranexamic acid has been found to reduce blood loss and the need for blood transfusions in knee arthroplasty. In hip arthroplasty, the benefit of tranexamic acid is not as clear.

Patients And Methods: In a randomized, double-blind study, 39 patients with primary cemented hip arthroplasty for osteoarthritis were divided into two groups; one receiving tranexamic acid and the other not receiving it.

Poor correlation of clinical signs with patellar cartilaginous changes.

PURPOSE: There is controversy between the symptoms and signs of chondromalacia. Patellar chondromalacia has several clinical tests, whose reliability as a parameter of chondral damage is unclear. The purpose of this prospective study was to correlate the sensitivity, specificity, predictive values and accuracy of clinical patellar tests with the findings at arthroscopy.
