    Abstract:
    BACKGROUND: Anterior cruciate ligament reconstruction (ACLR) is reportedly associated with a higher incidence of deep vein thrombosis (DVT) incidence than other arthroscopic surgical procedures. The aim of this study is to retrospectively investigate the incidence and type of DVT and evaluate the relationship between DVT and risk factors among all patients who underwent ACLR under uniform conditions consisting of mechanical prophylaxis, no medical prophylaxis, and preoperative and postoperative lower extremity venous ultrasonography. METHODS: Of the 114 patients who underwent arthroscopic primary ACLR at our hospital who did not have a compound ligament injury or revision surgery, 112 patients were included. Two patients were not examined. DVT evaluation consisted of whole-leg ultrasonography at 1 week after surgery. We evaluated age, sex, body mass index, comorbidities, operative time, tourniquet time, presence of concurrent surgery (meniscus repair/resection or osteochondral column grafting), and non-weight-bearing status at 1 week after surgery as risk factors for DVT. RESULTS: DVT was found in 33 (29.5%) of 112 patients. Of these, 22 (19.6%) had distal DVT and 11 (9.8%) had proximal DVT. Non-weight-bearing status at 1 week after surgery was a statistically significant risk factor for proximal DVT (P = .034). CONCLUSIONS: Non-weight-bearing status is an independent risk factor for DVT, suggesting that early weight bearing may reduce the occurrence of DVT.
