研究概要

One hundred patients with knee osteoarthritis (OA) scheduled for a unilateral total knee arthroplasty (TKA) were randomized to receive an intra-articular injection of dexamethasone (n=50) or peri-articular injection of triamcinolone acetonide (n=50). Outcomes of interest included the following: pain which was evaluated using the Numeric Rating Scale (NRS) at rest and during walking, nausea measured on NRS, incidence of vomiting, mean number of uses of rescue analgesia, number of patients with a fever, and mean number of uses of metoclopramide. Furthermore, inflammatory and serum markers were measured including levels of interleukin-6 (IL-6), C-reactive protein (CRP), and prothrombin fragment 1.2 (PF1.2), fasting blood glucose, and D-dimer. Pain at rest was measured at 4, 8, 16, 24, 48, and 72 hours and 1 week follow-up whereas pain during walking was measured at 24, 48, and 72 hours and 1 week follow-up. The number of uses of metoclopramide and rescue analgesia, and the incidence of vomiting were measured at 24-hours post-surgery. Nausea severity on a NRS was measured at 8, 24, and 48 hours post-surgery. Levels of IL-6 and CRP were measured at 24 and 48 hours, and CRP was measured at 1 week follow-up. Lastly, PF1.2 was only evaluated at 4 hours whereas D-dimer was measured at 24 and 48 hours and 1 week post-surgery. Results revealed that mean NRS pain during rest and pain during walking at 24 hours were statistically significantly reduced in the peri-articular injection group compared to the intravenous injection group(p<0.01 for both). Also, PF1.2 was also statistically significantly higher in the peri-articular injection group vs. the intravenous injection group at 4 hours post-surgery (p=0.006). CRP levels were statistically significantly lower in the intravenous injection group at 24 and 48 hours post-surgery, but statistically significantly higher at 1 week follow-up when compared to the peri-articular injection group (p<0.05 for all). All other outcomes at all other timepoints were not statistically significantly different between the 2 groups (p>0.05 for all). Two cases of deep vein thrombosis were observed in each arm, and no incidence of infection or delayed wound healing were observed in either group.
