Abstract
OBJECTIVE: To compare the therapeutic effects between drainage blood reinfusion and temporary clamping drainage after total knee arthroplasty in patients with rheumatoid arthritis to provide a basis for clinical practice. METHODS: Data from 83 patients with rheumatoid arthritis undergoing total knee arthroplasty were retrospectively analyzed. The 83 patients were divided into a drainage blood reinfusion group (DR group, n = 45) and a temporary clamping drainage group (CD group, n = 38). In the DR group, postoperative drainage blood was used for autotransfusion. In the CD group, closed drainage was adopted, and the drainage tube was clamped for 2 h postoperatively followed by patency. The postoperative drainage amount, hemoglobin level, rate and average volume of allogeneic blood transfusion, swelling and ecchymosis of the affected knee joint, time to straight-leg raising and range of active knee flexion were compared between the two groups. RESULTS: The total drainage volume was higher in the DR group than in the CD group (P = 0.000). The average volume of postoperative allogeneic blood transfusion (P = 0.000) and the decrease in the hemoglobin level 24 h after total knee arthroplasty (P = 0.012) were lower in the DR group than in the CD group. Swelling and ecchymosis of the affected knee joint, time to straight-leg raising and the range of active knee flexion were improved in the DR group compared with the CD group (all P<0.05). CONCLUSION: Compared with temporary clamping drainage, drainage blood reinfusion after total knee arthroplasty can reduce the allogeneic blood transfusion volume and is conducive to early rehabilitation in patients with rheumatoid arthritis.
