Impact of Tourniquet on Blood Loss and Postoperative Recovery in Total Knee Arthroplasty: A Randomized Clinical Trial |
|
| چکیده انگلیسی مقاله |
Background: Total knee arthroplasty (TKA) is an effective surgical procedure for alleviating pain and improving function in patients with severe knee osteoarthritis. However, significant intraoperative blood loss is a common concern, often necessitating blood transfusions and increasing the risk of complications. A tourniquet during TKA is a widely accepted technique to reduce blood loss and improve implant fixation, but it may lead to postoperative pain and restricted range of motion (ROM).
Objectives: This randomized clinical trial aimed to compare intraoperative blood loss, postoperative ROM, and pain in patients undergoing TKA with and without a tourniquet.
Methods: A total of 34 patients were randomized into two groups: 18 patients in the tourniquet group (TG) and 16 in the non-tourniquet group (NTG). Intraoperative blood loss, postoperative hemoglobin levels, ROM, thigh pain, and straight leg raise (SLR) were measured at multiple intervals postoperatively.
Results: The results showed that the TG group had significantly lower intraoperative blood loss (236.11 mL vs 531.25 mL, P<0.001) and higher postoperative hemoglobin levels than the NTG group. However, the TG group experienced significantly lower ROM on the first and second postoperative days (P<0.001) and reported greater thigh pain. By six months postoperatively, the two groups had no significant difference in ROM.
Conclusion: Using a tourniquet in TKA significantly reduces intraoperative blood loss but is associated with increased immediate postoperative pain and reduced early ROM. However, these adverse effects do not persist long-term. Individualized patient care and strategies to optimize tourniquet use are recommended to balance these outcomes. |
