Background Minimizing intra-articular bleeding and swelling is crucial in preventing the development of stiffness around the elbow. Tranexamic acid (TXA) has been shown to be an effective adjunct in reducing perioperative bleeding after surgery. Purpose: To determine the effect of intravenous (IV) TXA on postoperative drain tube output in arthroscopic osteocapsular release of the elbow for primary degenerative arthritis. Study Design: Cohort study; Level of evidence, 3. Methods: The authors performed a retrospective cohort study of 83 consecutive patients with primary degenerative elbow arthritis who underwent an arthroscopic osteocapsular release between 2015 and 2018. They organized patients into a no-TXA group (control) and a group that was given 1.0 g of IV TXA before tourniquet release. The primary outcome measure was drain tube output, and secondary outcome measures included postoperative day 1 pain levels on a visual analog scale and early range of motion at 8 weeks. Differences between groups were analyzed using 1-way analysis of variance, the Mann-Whitney U test, or the Fisher exact test. Results: There were 43 patients in the no-TXA group and 40 patients in the TXA group. Administration of IV TXA resulted in a 51% decrease in mean intra-articular bleeding for the TXA group, as measured via drain tube output (88.8 ± 80.5 mL [no-TXA] vs 43.4 ± 52.4 mL [TXA]; P = .0016). In both groups, there were significant increases in elbow arc of motion when compared with preoperative measurements. There were no between-group differences in early range of motion (129.7° ± 12.4° [no-TXA] vs 131.7° ± 9.2° [TXA]; P = .549) or postoperative pain (1.9 ± 2.2 [no-TXA] vs 1.5 ± 1.7 [TXA]; P = .89). Conclusion: In this study, IV TXA significantly reduced postoperative intra-articular bleeding in patients who underwent arthroscopic osteocapsular release of the elbow for primary degenerative arthritis. However, there were no differences in postoperative range of motion or pain between patients who received TXA and controls. |
