This study is a prospective randomized controlled study of different arthroscopic treatments for elbow stiffness combined with tranexamic acid(TXA) injection. The patients with stiffness were randomly divided into groups before the operation. After the arthroscopic operation was completed, they were divided into a local TXA injection group and a control group (normal saline) to perform additional operations for reduction of hemorrhage. In different time periods, the quantitative and qualitative indicators including pain, functional score, range of motion, level of Hemoglobin, the circumference of the limb 10cm above and below the elbow, amount of hemorrhage, etc. were compared between groups at the same time period to evaluate the difference in the effect of arthroscopic treatment combined with TXA on the treatment of reduction of hemorrhage. Determine the effectiveness of TXA.
