BackgroundDeep vein thrombosis (DVT) is common after total joint arthroplasty (TJA), and can cause the sequela of post-thrombotic syndrome (PTS), which is associated with decreased quality of life and increased treatment cost. The purpose of this study is to determine the incidence and risk factors for PTS in patients with DVT following primary unilateral total knee and hip arthroplasty.MethodsWe conducted this follow-up study involving patients developing DVT after primary unilateral total knee arthroplasty or total hip arthroplasty at our institution between April 2010 and March 2017. Each patient received a follow-up clinical interview regarding PTS-related symptoms and signs. We introduced demographic, clinical, and surgical data into the analysis to identify the risk factors for PTS.ResultsA total of 182 patients with postoperative DVT were enrolled with a mean follow-up time of 3.6 years. The incidence of PTS was 9.3% in patients developing DVT after TJA. Malignancy (P = .033), previous surgery in ipsilateral lower extremity (P = .013), and blood transfusion (P = .022) appeared to be the risk factors for PTS.ConclusionWe determined the incidence and risk factors for PTS in patients with DVT following TJA. Preventive measures should be used for patients at high risk of PTS.Copyright © 2018 Elsevier Inc. All rights reserved.
