Objective To investigate the correlation between the Barthel index score and other factors before revision total hip arthroplasty (THA) and the incidence of lower extremity deep venous thrombosis (DVT). Methods The clinical data of 122 THA revision patients who met the selection criteria between April 2017 and November 2020 were retrospectively analyzed. There were 61 males and 61 females with an average age of 65.3 years ranging from 32 to 85 years. The causes of revision were periprosthetic infection (7 cases), periprosthetic fracture (4 cases), prosthesis dislocation (6 cases), and aseptic loosening (105 cases). The Barthel index score was 76.4±17.7, including 10 cases of grade 1, 57 cases of grade 2, 37 cases of grade 3, and 18 cases of grade 4. Univariate analysis was performed on the age, gender, body mass index, Barthel index score, positive D-dimer, history of diabetes, hypertension, history of tumor, history of cerebral infarction, history of smoking, and history of thrombosis in patients with and without DVT before operation. The risk factors of DVT before revision THA were further screened by logistic regression analysis, and the incidence of DVT before revision THA was compared among different Barthel index grade. Results Eleven patients (9.02%) were found to have preoperative DVT, all of which were intermuscular venous thrombosis. The causes of revision were periprosthetic infection in 1 case, periprosthetic fracture in 1 case, prosthesis dislocation in 1 case, and aseptic loosening of prosthesis in 8 cases. Univariate analysis showed that there were significant differences in age, gender, and Barthel index score between the two groups (P<0.05). Further logistic regression analysis showed that female, age ≥70 years, and Barthel index score <60 were independent risk factors for DVT before THA revision (P<0.05). Preoperative DVT occurred in 0 (0), 2 (3.5%), 3 (8.1%), and 6 (33.3%) patients with Barthel index grade 1, 2, 3, and 4, respectively. There was a correlation between Barthel index grade and the incidence of DVT before THA revision (P=0.001). Conclusion In patients undergoing revision THA, older age, female, and lower Barthel index score were associated with a higher incidence of preoperative DVT. For patients with low preoperative Barthel scores, preoperative screening for thrombosis should be emphasized.
