Total knee arthroplasty (TKA) is an effective treatment to reduce pain and restore joint mobility and function in end-stage osteoarthritis (OA) [Tourniquet use in TKA can provide a bloodless intraoperative field and dry bone surface for optimal cement work reduce intraoperative blood loss [The pros and cons of tourniquet use are uncertain, though many studies have reported its use in TKA. As a prospective study, the primary aim of this randomized trial was to assess the efficacy of tourniquet use for blood loss in primary TKA. The secondary aim was to compare perioperative complications with or without tourniquet use in TKA. We hypothesized that nontourniquet use does not increase blood loss but does reduce perioperative complications in TKA.
