However, some studies suggest it may be associated with certain complications. It is currently unclear whether using a tourniquet meaningfully changes outcomes compared to not using one. This study aims to assess whether both approaches result in similar outcomes within a clinically acceptable range.\n\nThe main question this study aims to answer is:\n\nIs total blood loss during surgery equivalent between TKA performed with a tourniquet and TKA performed without a tourniquet, within a predefined margin of ±100 mL?\n\nAdditional questions include:\n\nAre surgical field quality, postoperative pain, functional recovery, and complication rates comparable between the two techniques?\n\nResearchers will compare:\n\nTKA performed with a pneumatic tourniquet TKA performed without a tourniquet\n\nto determine whether outcomes between the two approaches are equivalent rather than whether one is superior to the other.\n\nParticipants will:\n\nBe randomly assigned to one of the two surgical groups using a computer-generated process Undergo standard total knee replacement surgery and routine perioperative care Have blood loss assessed during and after surgery Be monitored for pain, recovery of function, wound healing, and complications during hospital stay and follow-up visits\n\nThis study is designed as a randomized controlled equivalence trial to determine whether both surgical approaches produce comparable outcomes within clinically acceptable limits, in a standardized local setting.",[67,68],"Knee Osteoarthritis (OA)","Total Knee Anthroplasty",[70],"tourniquet use","NOT_YET_RECRUITING","2026-03-27",{"date":74,"type":75},"2026-04-01","ACTUAL",{"date":77,"type":61},"2026-06",{"date":79,"type":61},"2027-09",{"name":5,"class":6},1]
