Summary
Brief summary
The aim of this pilot study is assess the efficacy of tranexamic acid in reducing post-operative pain, swelling and range of motion in patients undergoing arthroscopic meniscectomies. It is a blinded study in which participants are randomised to receive one intraoperative dose of either intravenous tranexamic acid or placebo (saline). Data collected is as follows: pain (0-10 scale), Lysholm knee score and Tegener activity score (to assess function), range of motion (measured by goniometer), suprapatellar and mid-calf circumferences (to assess swelling). Each of these data sets is collected pre-operatively (on the morning of surgery) and at three time points post-operatively (3, 14 and 30 days).
