Objectives: We aimed to evaluate the effectiveness of postoperative autotransfusion method on prevention of the need of allogeneic blood transfusion in hip and knee arthroplasty. Methods: Seventy-four patients who underwent 77 hip and knee arthroplasty operations were randomized into control and study groups, and evaluated prospectively. In the knee group (39 patients; 30 females, 9 males; mean age 66.6 years), cemented, cruciate retaining, and bicompartmental arthroplasty was performed under tourniquet control; whereas in the hip group (35 patients; 24 females, 11 males; mean age 59.3 years) cementless arthroplasty with posterolate . . .ral approach was performed. None of the patients received preoperative and intraoperative allogeneic blood transfusion. The collected blood in the surgical area was transfused with autotransfusion system to the patients in the study groups at the end of the fourth hour postoperatively. The mean amounts of autotransfused blood in hip and knee groups were 413 mL and 480 mL, respectively. Allogeneic blood transfusion was applied to the patients with hemoglobin level below 8 g/dL, hematocrit level below 25%, and clinical symptoms of anemia. Results: Preoperative and postoperative hemoglobin-hematocrit levels did not differ significantly between study and control groups. Allogeneic blood transfusion was applied to one patient (5%) in study and 8 patients (38%) in control groups during knee arthroplasty (p=0.01); whereas 9 patients (53%) in study and 15 patients (79%) in control groups received allogeneic blood transfusion during hip arthroplasty (p=0.044). The amount of allogeneic blood transfusion in study groups was significantly lower than that in control groups (p=0.008 for knee arthroplasty, p=0.048 for hip arthroplasty). Conclusion: The need and amount of allogeneic transfusion were reduced with postoperative autotransfusion in both knee and hip arthroplasty groups with greater extent in knee arthroplasty. © 2010 Turkish Association of Orthopaedics and Traumatology Daha fazlası Daha az

Objective: We aimed to find out the distribution of etiological factors in patients who had total hip replacement for coxarthrosis. Methods: The medical records of the 965 hips of 886 patients operated with total hip replacement between 2001 and 2012 in two separate arthroplasty clinics were analyzed by two separate senior surgeons. Each patient's pre- and postoperative X-rays and demographic data such as gender, age, side and probable etiologic factors were noted. Results: Six hundred and eighty-four patients were women and 202 were men. The mean age were 62.7±14.3 (range: 16 to 91) in women, 58.8±17.1 (range: 25 to 91) in men. 52. . . .1% of the surgeries were performed on the right side, 39% on the left, and 8.9% bilaterally. In women 36.2% of the cases were primary coxarthrosis, while the etiology was developmental dysplasia of the hip (DDH) in 43.5% of the cases, avascular necrosis in 10%, romatoid diseases in 7%, slipped capital femoral epiphysis in 5%, posttraumatic coxarthrosis in 3.9%, pathologic coxarthrosis in 1.9%, and Perthes sequel in 1.7%. In men, 24.4% of the cases were primary coxarthrosis, while the etiology was avascular necrosis in 21% of the cases, DDH in 17.6%, posttraumatic coxarthrosis in 16.8%, romatoid diseases in 10.9%, Perthes sequel in 4.2%, slipped capital femoral epiphysis in 2.5%, and pathologic coxarthrosis in 2.5%. The most common etiologic factor was DDH with a rate of 37.1%. Conclusion: Despite the heterogeneity of our study population, our results may reflect the distribution of coxarthrosis etiologies in Turkey. Developmental dysplasia of the hip appears to be the most frequent cause of coxarthrosis among the patients undergoing total hip replacement. © 2013 Turkish Association of Orthopaedics and Traumatology Daha fazlası Daha az
