Summary

The aim of the study will be to compare functional outcomes, basic morphology results, number of blood transfusions, costs of hospitalization, and inflammation factors, following total knee replacement (with use of one type of endoprosthesis) comparing use of closed suction drainage (CSD). Use of closed suction drainage may have influence on patients functional outcome.

Detailed description

Patients with primary knee osteoarthritis will be included in a randomized controlled trial and assigned to total knee arthroplasty with or without closed suction drainage. Subjects will be evaluated preoperatively, 1-day, 3-, 6- and 12-month postoperatively. Change in morphology results will be measured by comparing preoperative and postoperative levels of haematocrite, haemoglobin, erythrocytes, and platelets. Change in the number of blood transfusions will be measured by analyzing the number of needed transfusion of packed red blood cells in the postoperative period during stay in the hospital. Change in levels of inflammation factors will be measured by analyzing the level of C-reactive protein in first and third day postoperatively. Change in body temperature wille be measured daily by analyzing body temperature from day of the surgery until the day of discharge from the hospital Presence of haematoma will be evaluated daily in the postoperative period by clinical examination. Change in Western Ontario and McMasters University Osteoarthritis Index (WOMAC) Pain Score will be measured from baseline (can be measured anytime to a maximum of one month before surgery) 3,6 and 12 months post-operatively Change in Western Ontario and McMasters University Osteoarthritis Index (WOMAC) Function Score will be measured from baseline (can be measured anytime to a maximum of one month before surgery) 3,6 and 12 months post-operatively Costs of hospitalization will be measured by comparing cost of hospitalization between two analyzed groups
