BACKGROUND: Blood loss in total knee arthroplasty (TKA) is an area of significant concern as it has an effect on patient morbidity and hospital stay. Among many different modalities to reduce blood loss, the use of Tranexamic acid has become a standard procedure nowadays. The aim of our study was to determine if Tranexamic acid alone decreases blood loss as an independent variable irrespective of other blood loss preserving measures. METHOD: This prospective non-randomized study included patients undergoing unilateral TKA by conventional method (Group 1) and computer-assisted TKA (Group 2)...

BACKGROUND: A tourniquet is usually used during anterior ankle arthroscopy to allow for improved visibility and reduced operation time. However, this has not been demonstrated to be true in clinical studies on knee arthroscopy, while limited tourniquet time has been described as a possible factor to lower the complication rate of ankle arthroscopy. The purpose of this randomized controlled trial was to examine the effect of tourniquet use on arthroscopic visualization, operative time, postoperative intra-articular bleeding, postoperative pain scores, and outcome of anterior ankle arthroscopy...

BACKGROUND: Wound complications following total ankle replacement (TAR) potentially lead to devastating consequences. The aim of this study was to compare the operative and demographic differences in patients with and without major wound problems which required operative management. We hypothesized that increased tourniquet and operative time would negatively influence wound healing. METHODS: We identified a consecutive series of 762 primary TARs performed between December 1999 and April 2014 whose data were prospectively collected...

BACKGROUND: Blood loss is a major concern in total knee arthroplasty (TKA) along with postoperative knee function. The present study explores the impact of tourniquet (T) and closed-suction drains (D) on these parameters in TKA. MATERIALS AND METHODS: A prospective study was conducted on 111 patients admitted for TKA. Subjects were divided into three groups: 36 in group T+D+, 42 in T-D+ and 33 in T-D- (where T+: prolonged tourniquet use, T-: cementation-only tourniquet, D+: closed-suction drain use, and D-: no drain)...

BACKGROUND: Air tourniquet-induced skeletal muscle injury increases the concentrations of some cytokines such as interleukin-6 (IL-6) in plasma. However, the effect of an air tourniquet on the IL-6 concentrations after total knee arthroplasty (TKA) is unclear. We therefore investigated the impact of tourniquet-induced ischemia and reperfusion injury in TKA using the IL-6 level as an index. METHODS: Ten patients with primary knee osteoarthrosis who underwent unilateral TKA without an air tourniquet were recruited (Non-tourniquet group)...

BACKGROUND: Drainage and tranexamic acid (TXA) have been widely used in total knee arthroplasty (TKA). However, it remains unclear whether it is necessary to clamp the drain after minimally invasive TKA (MIS-TKA) when TXA is used. We therefore conducted a randomized controlled trial to compare the effects of clamping versus not clamping drainage following MIS-TKA in patients in whom TXA was used. METHODS: From January 2015 to December 2015, 121 patients undergoing unilateral primary MIS-TKA were enrolled and randomly divided into 2 groups...

OBJECTIVE: Our study is aimed to explore effects of five treatment regimens on blood loss and blood transfusion rate in total knee arthroplasty (TKA) patients. METHODS: 191 TKA patients were divided into the rivaroxaban, nadroparin, and tranexamic acid groups (n = 37 each) as well as into the affected-limb-position and tourniquet group (n = 40 each). A 3-month follow-up after operation was needed for all patients. The total blood loss, hidden blood loss, and dominant blood loss were recorded, and hemoglobin and red blood cell changes, pain and knee swelling degrees, hospital for special surgery (HSS), and American knee society (KSS) knee scores were observed...

COMPARATIVE STUDY
Vicente J León, María A Lengua, Víctor Calvo, Alonso J Lisón
Total knee arthroplasty (TKA) is associated with substantial blood loss. Sources of bleeding are the femoral and tibial intramedullary canals, which are violated during implantation using standard instrumentation. Patient-specific instrumentation (PSI) and computer-assisted surgery (CAS) do not require violation of the intramedullary canals. Therefore, we sought to assess the impact of these methods on blood loss and transfusion requirement. A retrospective cohort study was conducted in a series of 107 consecutive primary TKAs...

Bilateral total knee arthroplasty (BTKA) patients may require blood transfusion which has its risks. Anti-fibrinolytic drugs such as aprotinin, aminocaproic acid and tranexamic acid (TXA) have reduced transfusion requirements in major surgery. This retrospective audit was performed to assess effectiveness of TXA in reducing blood transfusion rate in single-stage sequential BTKA cases operated by a single surgeon. Records of 91 patients given TXA and 80 controls who were operated before 2012 and not given TXA were reviewed...

INTRODUCTION: Stiffness and loss of motion following total knee arthroplasty (TKA) is a complex and multifactorial complication that may require manipulation under anesthesia (MUA). However, patient and surgical factors that potentially influence the development of knee stiffness following TKA are not fully understood. The purpose of this study was to identify patient and surgical factors that may influence range of motion loss following TKA by assessing a cohort of patients that underwent MUA and comparing them to a matched cohort of patients without complications...
