Objectives: The purpose of this study was to evaluate the effect of intra-articular injection of fibrinogen on postoperative bleeding following total knee arthroplasty. Methods: A double-blind randomized clinical trial was conducted on 40 patients aged 40 - 70 years under spinal anesthesia candidate for total knee arthroplasty in Golestan hospital, Ahwaz, Iran, in 2017-2018. Patients were divided into fibrinogen intra-articular injection (n = 20) and control (n = 20) groups. The amounts of blood loss and blood transfusion requirement were recorded. Hemoglobin (Hb), hematocrit (HCT), international normalized ratio (INR), platelet (PLT), prothrombin time (PT), and partial thromboplastin time (PTT) were recorded before and after the surgery. Results: There was no significant difference in the average amount of intraoperative blood loss between the groups (P > 0.05). The average amount of blood loss 24 hours after the surgery was significantly lower in the fibrinogen group than in the control group (fibrinogen group 350.61 ± 120.32 cc; control group 540.00 ± 170.21 cc; P = 0.0002). There were significant differences in transfusion between the groups (fibrinogen group 250 ± 20 cc; control group 350 ± 50 cc; P < 0.0001). There was a significant difference between the two groups in 24 h postoperative Hb and HCT (P < 0.001). Conclusions: Intra-articular fibrinogen administration may reduce acute bleeding and can be used as an effective intervention to prevent further bleeding and the need for transfusion in patients undergoing total knee arthroplasty.

AbstractSeveral methods were introduced to limit perioperative blood loss in total knee arthroplasty (TKA). By transcollation of soft tissues below 100°C, bipolar sealers intend to reduce bleeding and tissue damage, compared with conventional electrocautery. Existing studies report contradictory findings about the performance of bipolar sealers. The purpose of this study was to evaluate the effect of a bipolar sealer on blood loss, transfusions, hospital length of stay (LOS), and functional scores in primary TKA. In this single-center prospective study, 101 patients, undergoing primary TKA in a fast-track setting without tourniquet use, were randomly assigned to either (1) the study group which was operated with a bipolar sealer or (2) the control group operated with conventional electrocautery. The study cohort comprised 49 men and 52 women, aged 71.1 ± 8.8 years. There was no significant difference between the bipolar sealer group and the control group in terms of blood loss at day 3 (1,240 ± 547.4 vs. 1,376 ± 584.4 mL; p = ns [not significant]), transfusion rate (10 vs. 4%; p = ns), surgery time (48.2 ± 10.8 vs. 46.6 ± 9.1 minute; p = ns) or LOS (4.1 ± 2.7 vs 4.3 ± 2.0 days; p = ns). At a mean follow-up of 63.3 ± 4.9 days, there was no significant difference between the bipolar sealer group and the control group in terms of net improvement of Knee Society Score (KSS) knee (26.0 ± 16.7 vs. 23.7 ± 12.3; p = ns) and KSS function (20.4 ± 19.3 vs. 20.8 ± 19.9; p = ns). Compared with the use of conventional electrocautery in primary TKA without tourniquet, we found no effect of bipolar sealer use on blood loss, transfusion rates, LOS, or functional recovery. This is a Level II, prospective cohort study.

Purpose: Patients with haemophilia suffer from recurrent joint haemarthrosis. This can progress to symptomatic arthropathy commonly affecting the knee. While modern coagulation strategies have reduced those proceeding to end-stage arthropathy, total knee arthroplasty (TKA) remains the optimal treatment for some patients. Despite innovation in perioperative haematological management, concerns about the potential for excessive haemorrhage still exist. The aim of this study is to quantify immediate postoperative blood loss and haematological complications in haemophiliacs following TKA. Methods: A retrospective study of patients with haemophilia types A or B who underwent a TKA over a 12-year period at a single institution was conducted. These patients were compared to both a non-haemophiliac control group and to published standards in non-haemophiliacs undergoing TKA. Results: Twenty-one TKA procedures in 18 patients (72% haemophilia A, 28% haemophilia B) were suitable for inclusion with a mean age of 44 years. The mean haemoglobin drops at 24 and 48 h postoperatively were 2.7 g/dl and 3.8 g/dl respectively. There was no significant difference in haemoglobin drop at 48 h postoperatively when compared to the non-haemophiliac control group ( P = 0.2644). There were no immediate perioperative complications and two patients (9.6%) required postoperative transfusion. Conclusion: Haemophiliacs undergoing a unilateral primary TKA in a specialised tertiary referral centre appear to have comparable rates of perioperative blood loss when compared to both a non-haemophiliac control group as and published haemostatic standards in non-haemophiliac patients following TKA. Perioperative management with expert orthopaedic and haematological input is recommended to optimise outcomes in this complex patient group.

Revision Tka

Aims Tranexamic acid (TXA) is proven to reduce blood loss following total knee arthroplasty (TKA), but there are limited data on the impact of similar dosing regimens in revision TKA. The purpose of this multicentre randomized clinical trial was to determine the optimal regimen to maximize the blood-sparing properties of TXA in revision TKA. Patients and Methods From six-centres, 233 revision TKAs were randomized to one of four regimens: 1 g of intravenous (IV) TXA given prior to the skin incision, a double-dose regimen of 1 g IV TXA given both prior to skin incision and at time of wound closure, a combination of 1 g IV TXA given prior to skin incision and 1 g of intraoperative topical TXA, or three doses of 1950 mg oral TXA given two hours preoperatively, six hours postoperatively, and on the morning of postoperative day one. Randomization was performed based on the type of revision procedure to ensure equivalent distribution among groups. Power analysis determined that 40 patients per group were necessary to identify a 1 g/dl difference in the reduction of haemoglobin postoperatively between groups with an alpha of 0.05 and power of 0.80. Per-protocol analysis involved regression analysis and two one-sided t-tests for equivalence. Results In total, one patient withdrew, five did not undergo surgery, 16 were screening failures, and 25 did not receive the assigned treatment, leaving 186 patients for analysis. There was no significant difference in haemoglobin reduction among treatments (2.8 g/dl for single-dose IV TXA, 2.6 g/dl for double-dose IV TXA, 2.6 g/dl for combined IV/topical TXA, 2.9 g/dl for oral TXA; p = 0.38). Similarly, calculated blood loss (p = 0.65) and transfusion rates (p = 0.95) were not significantly different between groups. Equivalence testing assuming a 1 g/dl difference in haemoglobin change as clinically relevant showed that all possible pairings were statistically equivalent. Conclusion Despite the higher risk of blood loss in revision TKA, all TXA regimens tested had equivalent blood-sparing properties. Surgeons should consider using the lowest effective dose and least costly TXA regimen in revision TKA. Cite this article: Bone Joint J 2019;101-B(Supple 7):10–16

Abstract Background: Total knee arthroplasty (TKA) is a highly complex and effective surgery even though its perioperative bleeding may increase the need for blood transfusion and its associated infection risk, cardiovascular overload, increased costs, and mortality. As tourniquet reduces intraoperative bleeding it may be associated with postoperative bleeding, venous thrombosis, and distal ischemia. The reperfusion may trigger a local and systemic inflammatory response. Anesthetic preconditioning (APC) with sevoflurane minimizes ischemia-reperfusion syndrome (I/R). This study evaluated the effects of APC with sevoflurane on perioperative bleeding in TKA.Methods: We allocated 30 patients into two groups: a sevo group (sevoflurane 2% for 15 minutes before the tourniquet) and a control group (propofol infusion). Laboratory tests were collected right before the tourniquet (LAB PRE, in the operating room) and after its release at four moments: LAB POST (immediately after), LAB 2 (two hours after), LAB 12 (12 hours after), and LAB 24 (24 hours after). The volume of the suction drain was measured at one, two, 12, and 24 hours after the end of the surgery. Antifibrinolytics were not administered.Results: There was no statistically significant difference in bleeding-related variables, such as drained volume and hemoglobin and hematocrit measurements. Drainage volume was higher in the first two hours after the procedure, while hematocrit decreased pre- to post-operatively and between two- and 12-hours post-procedure.Conclusion: Sevoflurane as an anesthetic preconditioning did not reduce postoperative bleeding in TKA surgery.Trial Registration: ClinicalTrials.gov – NCT03379103; December 20, 2017.
