A study by Mark A. Snyder, MD, Alexandra N. Sympson, BA, CCRC, Christina M. Scheuerman, RN, BSN, CCRC, Justin L. Gregg, MA, BDSCP, Lala R. Hussain, MSc, MHA


Aspirin at 325 mg twice daily is now included as a nationally approved venous thromboembolism (VTE) prophylaxis protocol for low-risk total knee arthroplasty (TKA) patients. The purpose of this study is to examine whether there is a difference in deep vein thrombosis (DVT) occurrence after a limited tourniquet TKA using aspirin-based prophylaxis with or without extended use of mechanical compression device (MCD) therapy.


The DVT rate for the postdischarge MCD therapy group was 0% and 23.1% for the inpatient MCD group (P < .001). All DVTs resolved by 3 months postoperatively. Patient satisfaction was 9.56 (±0.82) for postdischarge MCD patients vs 8.50 (±1.46) for inpatient MCD patients (P < .001).

This study was published in The Journal of Arthroplasty.
