Purpose:
To determine whether tranexamic acid (TXA) is safe to administer preoperatively in patients undergoing hip arthroscopy by comparing the venous thromboembolic rate and complication rate between patients who did and did not receive TXA preoperatively.
Methods:
This was a multicenter consecutive-cohort series of patients who underwent arthroscopic hip surgery between 2014 and 2021. The 2 cohorts comprised patients who did and did not receive TXA preoperatively (single dose of 1-2 g), after a practice change. Data were collected via chart review. Surgical outcomes included days until follow-up, visual analog scale pain score at first follow-up, total operating room (OR) time, number of arthroscopic fluid bags (3 L/bag), and complications and revision operations up to 1 year after surgery. The Mann-Whitney U test was performed for continuous variables, and the χ2 test, for categorical variables.
Results:
A total of 862 patients were identified: 449 (52%) received TXA and 413 (48%) did not. Patient demographic characteristics including age, sex, height, weight, body mass index, smoking status, and procedures performed, as well as number of anchors used (3.5 anchors for no TXA vs 3.7 anchors for TXA) and traction time (38 minutes for no TXA vs 40 minutes for TXA), did not significantly differ between groups. Significantly more patients underwent prior hip arthroscopy in the TXA group (n = 45; primary, n = 404) than in the group that did not receive TXA (n = 25; primary, n = 388) (P = .03). Visual analog scale pain scores at the first follow-up visit (2.61 for no TXA vs 2.62 for TXA, P = .62) and the need for subsequent revision surgery (24 patients with no TXA vs 18 patients with TXA, P = .68) were not significantly different. TXA use was associated with less arthroscopic fluid utilization (5.9 bags of 3 L of fluid for no TXA vs 5.3 bags of 3 L of fluid for TXA, P < .01) and less total OR time (99.5 minutes for no TXA vs 90.0 minutes for TXA, P < .01). There was a higher overall complication rate in the group that did not receive TXA (n = 27) than in the group that did (n = 10) (P = .01). However, if lateral femoral cutaneous nerve neurapraxia was excluded, then no difference in complication rate was observed (P = .24).
Conclusions:
There was no difference in the incidence of venous thromboembolic complications between patients who did and did not receive TXA preoperatively. We observed a lower overall complication rate in patients who received TXA preoperatively; however, this normalized between the 2 groups when lateral femoral cutaneous nerve neuritis was excluded. No difference in early pain control or revision surgery rate was observed between groups. Although there was statistically less arthroscopic fluid utilization and less total OR time in the group that received TXA, further studies are needed to clarify whether this is clinically meaningful. Preoperatively administered TXA is a safe adjunct medication in patients undergoing arthroscopic hip surgery.
