Intra-articular Administration of 3.0g Tranexamic Acid Has no Effect on Reducing Intra-articular Hemarthrosis and Postoperative Pain After Primary Anterior Cruciate Ligament Reconstruction: A Randomized Controlled Trial

The purpose of this study was to investigate whether intraarticular administration of tranexamic acid could reduce hemarthrosis and postoperative pain in patients following anterior cruciate ligament reconstruction. The hypothesis of the study was that patients treated with intraarticular tranexamic acid would have significantly less postoperative hemarthrosis and less pain in the early phase of the rehabilitation process compared with those without intraarticular tranexamic acid .
