Blood Management Strategies in Total Knee Arthroplasty
( David Liu Fracs ),( Michael Dan Mbbs ),( Sara Martinez Martos Mbbs ),( Elaine Beller Bsc Mappstat ) 대한슬관절학회 2016 대한슬관절학회지 Vol.28 No.3
A perioperative blood management program is one of a number of important elements for successful patient care in total knee arthroplasty (TKA) and surgeons should be proactive in its application. The aims of blood conservation are to reduce the risk of blood transfusion whilst at the same time maximizing hemoglobin (Hb) in the postoperative period, leading to a positive effect on outcome and cost. An individualized strategy based on patient specific risk factors, anticipated blood loss and comorbidities are useful in achieving this aim. Multiple blood conservation strategies are available in the preoperative, intraoperative and postoperative periods and can be employed in various combinations. Recent literature has highlighted the importance of preoperative Hb optimization, minimizing blood loss and evidence-based transfusion guidelines. Given TKA is an elective procedure, a zero allogenic blood transfusion rate should be the aim and an achievable goal.

Effects of Tourniquet Use on Quadriceps Function and Pain in Total Knee Arthroplasty
( David Liu Fracs ),( David Graham Mbbs ),( Kim Gillies M Hlth. Sc ),( R. Mark Gillies ) 대한슬관절학회 2014 대한슬관절학회지 Vol.26 No.4
purpose: A pneumatic tourniquet is commonly used in total knee arthroplasty (TKA) to improve surgical field visualisation but may result in quadriceps muscle ischaemia. We performed this study to analyse the effect of the tourniquet on recovery following TKA. materials and methods: A prospective randomised single-blinded trial was undertaken to examine the effect of the tourniquet on post-operative pain, swelling, blood loss, quadriceps function and outcome following TKA. Twenty patients with osteoarthritis of the knee were randomised to tourniquet or no tourniquet groups. Quadriceps function was assessed using surface electromyography (EMG) during active knee extension. results: The no tourniquet group had significantly less pain in the early post-operative period compared to the tourniquet group. There was no difference in Oxford knee score, range of motion, or thigh and knee swelling up to 12 months post-operatively. Quadriceps function, measured by surface EMG, was compromised for the first six months post-surgery by tourniquet use. The radiological cement mantle at the bone prosthesis interface at 12-month follow-up was not affected by the absence of a tourniquet. conclusions: We believe that it is safe and beneficial for our patients to routinely perform TKA without a tourniquet.
