Abstract

We examined whether the preoperative time required for the Timed "Up and Go" (TUG) test could predict the risk for deep venous thrombosis (DVT) in patients with hip osteoarthritis after total hip arthroplasty (THA). Eighteen patients with DVT diagnosed by venography were selected, and 18 without DVT of the same age and sex and with the same operated side as the DVT group were selected as a control group. We evaluated the 5 preoperative factors that might affect the occurrence of DVT complications, as follows: disease duration, body mass index, serum total cholesterol, subjective pain evaluated by the visual analog scale, and TUG. The JOA hip score (pain, range of motion, walking ability, and daily life) was also evaluated before surgery. As a postoperative factor, we checked the postoperative day when weight-bearing was initiated. As a result, TUG (DVT, 18.4 ± 4.0 sec vs. control, 15.0 ± 3.2 sec; p < 0.01) was only significantly different between the 2 groups. The ROC curve revealed that the cut-off point of 15.3 sec in preoperative time for TUG was sensitive (83.3%) and specific (61.1%) for DVT after THA (odds ratio = 7.0; 95% confidence interval, 1.630.8). These results suggested that low preoperative ambulatory ability in patients with hip osteoarthritis might be associated with DVT after THA. An improvement in TUG before surgery might contribute to a decrease in the occurrence of DVT after THA.
