The Incidence Of Deep Venous Thrombosis After Arthroscopically Assisted Anterior Cruciate Ligament

Purpose:The purpose of our study was to retrospectively assess and analyze the incidence of deep venous thrombosis (DVT) after arthroscopically assisted anterior cruciate ligament reconstruction (ACLR) at our institution. Methods:We conducted a retrospective analysis of249arthroscopic ACLRs performed in our hospital between February2009and February2012. The surgical procedure was standardized in all the patients and was conducted by the same2surgeons. Quadrupled hamstring autograft was used in all the patients. No patient was given nonsteroidal anti-inflammatory drugs for the first2weeks after surgery. A unilateral contrast venography examination was performed on the third postoperative day. Patients were confined to bed once DVT was confirmed, followed by therapeutic doses of batroxobin. The proportion of patients with DVT was calculated. The significance of the association between clinical factors and postoperative DVT was determined. Results:This study included171patients (123men and48women), with a mean age (+SD) of30.1±10.0 years. DVT was detected in24patients (14.0%;95%confidence interval,8.8%to19.3%). Body mass index (BMI), operative time, operator, and duration of tourniquet application were not significant risk factors for DVT. The risk of DVT was significantly higher in patients aged35years or older (P<.01). Higher risk for DVT was also identified in female patients (P<.05). Pulmonary embolism did not develop after thrombolytic therapy in any of the24patients with DVT after ACLR. Conclusions:The incidence of DVT in patients who underwent arthroscopic ACLR was14%in this study. Female patients and those aged35years or older have a significantly higher risk of DVT developing after ACLR; thus thromboprophylaxis is advocated in these patients.
