Half-dose may be equivalent to full-dose anticoagulants in preventing venous thromboembolism after primary total joint arthroplasty: a single center comparative retrospective cohort study

Half-dose of DVT prophylaxis drugs during the perioperative period of TJA does not elevate DVT incidence. Furthermore, it significantly decreases TBL and shortens hospital stays, while having no adverse impact on postoperative joint function recovery. These findings may support the implementation of half-dose protocol anticoagulants in the TJA protocol.
