Regarding the RA disease activity and severity of joint damage, patients with RA in the ABT group exhibited significantly higher ESR (50.0 vs. 37.0 mm/h, P < 0.001) and CRP (17.7 vs. 13.1 mg/L, P = 0.013), while the preoperative PT level (11.6 vs. 11.9 s, P < 0.001) was significantly lower in the ABT group than the non-ABT group. Here, CRP is linked to rheumatoid arthritis.
