Abstract
Iron supplementation provides iron storage and facilitates effective production of hemoglobin. The purpose of this study was to investigate the effect of early postoperative intravenous (IV) iron supplementation in different types of total knee arthroplasty (TKA) surgery. We retrospectively analyzed 863 patients who underwent TKA between September 2017 and September 2021. The IV iron (I) and non-IV iron (NI) groups were compared. Hemoglobin responders, defined as patients who showed a change in hemoglobin level of ≥2 g/dL at 6 weeks of surgery compared to the baseline immediate postoperative hemoglobin level, were identified and they were compared with the nonresponders. After logistic regression analysis, the patients were classified according to the type of surgery (unilateral TKA, staged bilateral TKA, and simultaneous bilateral TKA). A subgroup analysis was performed according to the comorbidity as Charlson Comorbidity Index (CCI). The type of surgery and the rate of hemoglobin responders differed between the I and NI groups. The surgery type and iron supplementation significantly affected the hemoglobin responder in the logistic regression model. In each surgery type, hemoglobin drop in the I group was generally lower in the second and sixth weeks than that in the NI group. It was also effective in reducing hemoglobin drop on the first day of the second surgery in staged bilateral TKA. In addition, the number of hospital days was lower in the IV iron supplementation group who underwent a staged bilateral TKA. CCI did not affect hemoglobin responder, hemoglobin drop, and transfusion rate in both the I and NI groups. Postoperative IV iron supplementation affected the outcome of hemoglobin responders. In addition, it reduced early postoperative hemoglobin drop. However, iron supplementation did not affect the transfusion rate, complications, and clinical outcome, regardless of the type of surgery. LEVEL OF EVIDENCE: Level III, case-control study.

Comparison of hematologic data and postoperative transfusion rate between a prophylactic allogenic or autologous transfusion group with a no-transfusion group: A preliminary retrospective cohort study. Transfus Clin Biol 2024; 31:70-75. [PMID: 38211936 DOI: 10.1016/j.tracli.2024.01.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Revised: 12/20/2023] [Accepted: 01/03/2024] [Indexed: 01/13/2024]
Abstract
OBJECTIVES To determine whether prophylactic intra-operative allogenic or autologous transfusion could prevent postoperative anemia and additional transfusion comparing to the control group without receiving any prophylactic intervention in unilateral total knee arthroplasty. MATERIALS AND METHODS This study included 711 patients who underwent unilateral TKA. They were divided into four groups: allogeneic transfusion group (group AL), autologous transfusion group (group AT), tranexamic acid group (group TA), and control group (group C). The primary outcome was rate of postoperative allogeneic blood transfusions. Secondary outcomes were postoperative hemoglobin and hematocrit levels, postoperative bleeding amount. RESULTS Groups AT and AL did not exhibit a significant reduction in postoperative allogenic blood transfusion rate compared to group C (28/108 vs. 20/108, p = 0.21 and 37/159 vs. 34/159, p = 0.78 respectively). However, group TA demonstrated a significantly lower rate of postoperative allogenic blood transfusions than group C (22/125 vs. 3/125, p = 0.0001). Postoperative hemoglobin and hematocrit levels were statistically higher in group TA than in group C. However, those levels in group AT and AL did not differ significantly from those of group C. CONCLUSION Intra-operative prophylactic transfusions did not decrease postoperative anemia or additional postoperative transfusion compared to the control group in patients undergoing total knee arthroplasty. However, the group receiving tranexamic acid showed lower transfusion rate and higher levels of hemoglobin and hematocrit.

Abstract
BACKGROUND Blood loss during and after total knee arthroplasty (TKA) can lead to substantial morbidity and the need for blood transfusions. There are several methods to minimize blood loss and decrease transfusion rates in patients undergoing TKA. Tranexamic acid, an antifibrinolytic agent with known efficacy for achieving these goals, is combined with tourniquets to reduce bleeding in arthroplasty surgeries. Our study investigated the effects of various combinations of tranexamic acid and tourniquet use on bleeding in knee arthroplasty in 558 patients. AIM We aimed to determine the method that would provide the least blood loss and transfusion need in knee arthroplasty surgery. METHODS Between January 2018 and December 2022, 558 patients aged between 55 and 85 years underwent TKA surgery for grade 4 gonarthrosis in our clinic, and their decrease in hemoglobin value and whether they were transfused or not were analyzed. The patients were divided into four groups based on use of tranexamic acid and tourniquet. Demographic variables and patient data (body mass index, INR values, and preoperative hemoglobin values) were recorded. RESULTS There were 558 patients with a mean age of 68.19 (67 ± 6.949) years. In group 1, tranexamic acid was not used in 128 patients and tourniquet was used only during cementation; in group 2, in 132 patients, tranexamic acid was not used and tourniquet was used throughout the surgery; in group 3, in 158 patients, tranexamic acid was used and tourniquet was used throughout the surgery; in group 4, in 140 patients, tranexamic acid was used and tourniquet was used only during cementation. The decrease in hemoglobin value and transfusion rate was lowest in group 3 and highest in group 1. Besides, there was a greater decrease in hemoglobin value in group 2 than in group 4 and the transfusion rate was similar. CONCLUSIONS This clinical study showed that using tranexamic acid and a tourniquet throughout surgery significantly reduced the decrease in hemoglobin value and the need for transfusion.

Clin Orthop Surg 2023; 15:942-952. [PMID: 38045586 PMCID: PMC10689217 DOI: 10.4055/cios22312] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2022] [Revised: 12/23/2022] [Accepted: 01/05/2023] [Indexed: 12/05/2023] Open
Abstract
Background This study aimed to evaluate the annual trends of transfusion rates and utilization of blood management agents in total knee arthroplasty (TKA) based on the operation type and to analyze the risk factors of transfusion after TKA. Methods Using the Korean National Insurance claims database of 797,106 primary and revision TKAs between January 2008 and October 2019, data on the patients' characteristics, comorbidities, utilization of transfusion, and blood management agents were collected. The patients were categorized into three groups based on the operation type: primary, revision, and simultaneous bilateral TKA. The transfusion rate and utilization of blood management agents (intraoperative tranexamic acid [TXA] and preoperative iron supplements) were compared, and the risk factors for transfusion were evaluated. Results After excluding the inaccurate data, 730,554 arthroplasties (636,292 primary, 10,540 revision, and 41,861 simultaneous bilateral TKAs) were identified. The transfusion rates of primary, revision, and simultaneous bilateral TKAs in 2019 were 64.0%, 67.7%, and 68.9%, respectively, which were significantly decreased compared with 83.2%, 88.0%, and 92.5% in 2008, respectively (p < 0.001). Conversely, the utilization of intraoperative TXA and preoperative iron supplements was significantly increased from 4.6% and 13.8%, respectively, in 2008 to 52.4% and 27.0%, respectively, in 2019 (p < 0.001). The utilization of intraoperative TXA and preoperative iron supplements significantly lowered the risk of transfusion after TKA (odds ratio [OR], 0.20; p < 0.001 and OR, 0.71; p < 0.001). Conclusions The transfusion rate after TKA decreased gradually from 83.5% to 64.5% between 2008 and 2019 in South Korea corresponding with the increased utilization of blood management agents. Therefore, consistent attention to patient blood management should be emphasized to reduce the transfusion rate after TKA.

Effects of intraoperative or postoperative administration of intravenous iron supplements on hemoglobin recovery in patients with total knee arthroplasty: A systematic review and meta-analysis. Medicine (Baltimore) 2023; 102:e35744. [PMID: 37904349 PMCID: PMC10615465 DOI: 10.1097/md.0000000000035744] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/30/2023] [Accepted: 09/29/2023] [Indexed: 11/01/2023] Open
Abstract
BACKGROUND The objectives of the researchers are as follows: First, to investigate whether intraoperative or postoperative administration of Intravenous (IV) iron supplements in patients undergoing primary total knee arthroplasty (TKA) can contribute to the hemoglobin recovery during the postoperative period (between 4 and 8 weeks after surgery). Second, to examine whether the administration of IV iron supplements during or immediately after TKA in patients undergoing primary TKA can reduce the need for allogenic blood transfusion during hospitalization. METHODS Articles published between January 1, 1990, and June 30, 2023 were searched in PubMed, Cochrane, and Embase. The population, intervention, comparison, and outcome of this study are as follows; Population: Patients undergoing primary total knee arthroplasty; Intervention: Administration of IV iron supplements during or immediately after surgery; Comparison: Non-administration of IV iron supplements; Outcome: Degree of hemoglobin recovery (between 4 and 8 weeks after surgery) and the need for blood transfusion during hospitalization. RESULTS There was a statistically significant difference in the amount of change in hemoglobin between iron supplementation group and non-iron supplementation group. The effect size were -0.44 (95% confidence interval: -0.69 to -0.19, P value < .001) in all patients. This means that the amount of change in hemoglobin were significantly reduced in the iron supplementation group than in the non-iron supplementation group. There was a statistically significant difference for post-operative transfusion rate between 2 groups. The effect size were 0.28 (95% confidence interval: 0.10-0.81, P value = .02) in all patients. This means that the post-operative transfusion rate was significantly less in the iron supplementation group than in the non-iron supplementation group. CONCLUSION The administration of IV iron supplements during or after TKA surgery increases hemoglobin recovery between 4 and 8 weeks after surgery and reduces the need for allogeneic blood transfusion during hospitalization.

Abstract
The effectiveness of Floseal, a thrombin-based hemostatic matrix, in total knee arthroplasty (TKA) in minimizing blood loss and transfusion requirements remains a topic of debate. This meta-analysis aims to evaluate the up-to-date randomized controlled trials (RCTs) on the efficacy and safety of Floseal in TKA. A comprehensive search was conducted in electronic databases to identify relevant RCTs. The methodological quality of the included studies was assessed, and data extraction was performed. The pooled effect sizes were calculated using standardized mean difference (SMD) or odds ratios (OR) with 95% confidence intervals (CIs). Eight studies involving 904 patients were included in the meta-analysis. The use of a thrombin-based hemostatic agent significantly reduced hemoglobin decline (SMD = -0.49, 95% CI: -0.92 to -0.07) and the risk of allogenic transfusion (OR = 0.45, 95% CI: 0.25 to 0.81) but showed no significant difference in the volume of drainage or total blood loss. Funnel plots showed no evidence of publication bias. This meta-analysis provides robust evidence supporting the effectiveness of Floseal in reducing hemoglobin decline and transfusion in TKA. Further well-designed RCTs with longer follow-up periods are warranted to assess long-term efficacy and safety.

Abstract
The transfusion rate in staged bilateral total knee arthroplasty (TKA) remains high despite the application of blood management techniques. The potential of robotic arm-assisted TKA (R-TKA) in reducing the transfusion rate in staged bilateral surgery has not yet been investigated. Therefore, we aimed to evaluate the effectiveness of R-TKA on transfusion reduction compared with conventional TKA (C-TKA) in staged bilateral surgery. This retrospective study involved two groups of patients who underwent 1-week interval staged bilateral TKA-the C-TKA group and the R-TKA group-using MAKO SmartRobotics (Stryker, Kalamazoo, MI, USA). Each group comprised 53 patients after propensity score matching and was compared in terms of nadir hemoglobin (Hb) level and transfusion rate after each stage of surgery. Both groups showed no significant differences in the propensity-matched variables of age, sex, body mass index, American Society of Anesthesiologists physical status score, and preoperative Hb level. The R-TKA group showed a significantly higher nadir Hb level than the C-TKA group after the second TKA (p = 0.002). The transfusion rate was not significantly different between the two groups after the first TKA (p = 0.558). However, the R-TKA group showed a significantly lower transfusion rate in the TKA (p = 0.030) and overall period (p = 0.023) than the C-TKA group. Patients who undergo staged bilateral R-TKA have lower transfusion rate than those who undergo C-TKA. R-TKA may be effective in minimizing unnecessary allogeneic transfusions in staged bilateral surgery.

Abstract
BACKGROUND Preoperative anemia is associated with adverse events following total knee arthroplasty (TKA). It remains unknown if this effect is due to comorbid conditions, adverse events associated with transfusions, or the anemia itself. We used propensity-score matching to isolate the effect of anemia on postoperative complications following TKA, regardless of blood transfusions. METHODS Patients undergoing primary TKA from 2010 to 2020 without receiving a perioperative blood transfusion, were identified using a large national database. A 1:1 propensity score matching was used to create cohorts of anemic and nonanemic patients matched on Charlson Comorbidity Index (CCI), American Society of Anesthesiology (ASA) classification, age, sex, and prevalence of bleeding disorders. There were 43,370 patients were included in each group (mean age 68 [range, 29 to 99; 44% male]). The 1:1 matching yielded groups with similar CCI, ASA classification, age, sex, and prevalence of bleeding disorders (all, P > .9). RESULTS Anemic patients had a higher incidence of major complications (4.1 versus 2.8%; P < .001), 30-day mortality rate (0.2 versus 0.1%; P < .001), and extended lengths of stay (LOS) (8.3 versus 6.6%; P < .001). Anemic patients also had increased 30-day rates of wound infection requiring hospital admission, renal failure, reintubation, myocardial infarction, and pneumonia (all, P < .001). CONCLUSION In matched cohorts of anemic versus nonanemic patients undergoing TKA, all who had no postoperative blood transfusion, anemic patients had higher rates of complications, extended LOS, and mortalities. Thus, anemia should be considered an independent risk factor for complications following TKA.

[PMID: 36449066 PMCID: PMC10293358 DOI: 10.1007/s00402-022-04698-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Accepted: 11/10/2022] [Indexed: 12/05/2022]
Abstract
INTRODUCTION Malalignment and resulting complications are major challenges in total knee arthroplasty (TKA) which patient-specific instrumentation (PSI) is proposed to alleviate. Previous PSI meta-analyses of TKA outcomes typically do not differentiate between PSI systems and assess relatively few outcomes, so the value of their findings is limited. VISIONAIRE™ cutting guides (Smith + Nephew Inc., Memphis, TN, USA) is a PSI system based on preoperative magnetic resonance and X-ray imaging. A systematic literature review (SLR) and meta-analysis, focussed specifically on VISIONAIRE, were conducted to assess TKA accuracy, intraoperative outcomes, and postoperative outcomes, compared with conventional instrumentation (CI). MATERIALS AND METHODS The SLR was performed using PubMed, Embase, and Google Scholar databases to identify relevant studies published until March 2022. Depending on statistical heterogeneity, meta-analyses were performed for outcome measures with fixed effect (I2 < 50%) or random-effects models (I2 ≥ 50%). Dichotomous outcomes were reported as odds ratios and continuous outcomes were reported as mean differences. Descriptive analyses were performed for outcomes not amenable to meta-analysis. RESULTS Outcomes for VISIONAIRE versus CI were reported in 25 studies. Compared with CI, VISIONAIRE reduced odds of mechanical outliers by 40% (p < 0.0001), with no statistically significant differences in odds of overall coronal, sagittal, or rotational plane component outliers. VISIONAIRE improved surgical efficiency (operating room, turnover, and tourniquet times reduced by 7.3% (p = 0.02), 42% (p = 0.022), and 15.9% (p = 0.01), respectively), lowering the odds of blood transfusion by 53% (p = 0.01) and shortening patients' hospital stays (11.1% reduction; p < 0.0001). There were no significant differences between groups in incidence of postoperative complications and (descriptively analyzed) return-to-function outcomes. CONCLUSION Options for PSI in TKA differ substantially, and it is important to assess the outcomes of individual systems. The current findings suggest that VISIONAIRE guides can lead to improved alignment accuracy and surgical efficiency compared with CI, without compromising postoperative safety and return-to-function outcomes.

[PMID: 37512024 PMCID: PMC10384006 DOI: 10.3390/medicina59071212] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/03/2023] [Revised: 06/21/2023] [Accepted: 06/26/2023] [Indexed: 07/30/2023]
Abstract
Background and Objectives: Total knee arthroplasty (TKA) involves blood loss, increasing the risk of postoperative anemia and delayed functional recovery. Intravenous (IV) iron supplementation limits postoperative anemia; however, the effectiveness of IV iron, administered one day before TKA, on postoperative anemia and functional recovery has scarcely been studied. Materials and Methods: We conducted a retrospective cohort study with propensity score matching using two consecutive groups of patients who underwent TKA using tranexamic acid: the iron group received 500 mg ferric derisomaltose intravenously one day before surgery (n = 46); the non-iron group did not (n = 46). Hemoglobin (Hb) level was determined at postoperative days (PODs) 2, 4, 6, 14, and 30. Ferritin, transferrin saturation (TSAT), and functional iron deficiency anemia (IDA) rate were measured at PODs 2, 4, 6, and 14. Length of hospital stay and transfusion rate were also evaluated. Results: The iron group had higher Hb levels at PODs 6, 14, and 30 and higher ferritin and TSAT at PODs 2, 4, 6, and 14. The functional IDA rate was significantly higher in the non-iron group at PODs 2, 4, 6, and 14. Length of hospital stay was significantly shorter in the iron group; however, the rate of transfusion did not differ between the two groups. Conclusions: IV iron administered one day before TKA was associated with postoperative anemia recovery and length of hospital stay; however, it did not lower the postoperative transfusion rate.

Abstract
We retrospectively investigated the natural course of hemoglobin levels after allogenic blood transfusion in total knee arthroplasty. All patients were treated according to the same clinical pathway, and blood tests were performed on the same day. All blood tests were done on pre-op, immediate post-op, midnight of op day, 1st, 2nd, 3rd, 5th, 7th, and 11th day after surgery. Of the total 593 cases, a total of 197 cases (33.2%) were performed within 3 days of surgery. Hemoglobin level was significantly lowest on the 3rd day after surgery and tended to increase afterwards in the non-transfusion group. In the case of blood transfusion on the day of surgery, the hemoglobin level showed an increase on the next day and then showed a minimum value on the fifth day of surgery and then increased. The same pattern was identified when blood transfusion was done on the 1st and 2nd day of surgery. However, when blood transfusion was done on the 3rd day, the hemoglobin level showed a steady increase afterwards. The hemoglobin level of total knee arthroplasty patients with no blood transfusion was the lowest on the 3rd day after surgery and increased afterwards. If blood transfusion was done within 2 days after surgery, the hemoglobin level was the lowest on the 5th day after surgery and increased afterwards. If blood transfusion was done on the 3rd day after surgery, the hemoglobin level increased afterwards.

Abstract
BACKGROUND Despite advancements in total hip arthroplasty (THA) and the increased utilization of tranexamic acid, acute blood loss anemia necessitating allogeneic blood transfusion persists as a post-operative complication. The prevalence of allogeneic blood transfusion in primary THA has been reported to be as high as 9%. Therefore, this study aimed to develop and validate novel machine learning models for the prediction of transfusion rates following primary total hip arthroplasty. METHODS A total of 7265 consecutive patients who underwent primary total hip arthroplasty were evaluated using a single tertiary referral institution database. Patient charts were manually reviewed to identify patient demographics and surgical variables that may be associated with transfusion rates. Four state-of-the-art machine learning algorithms were developed to predict transfusion rates following primary THA, and these models were assessed by discrimination, calibration, and decision curve analysis. RESULTS The factors most significantly associated with transfusion rates include tranexamic acid usage, bleeding disorders, and pre-operative hematocrit (< 33%). The four machine learning models all achieved excellent performance across discrimination (AUC > 0.78), calibration, and decision curve analysis. CONCLUSION This study developed machine learning models for the prediction of patient-specific transfusion rates following primary total hip arthroplasty. The results represent a novel application of machine learning, and has the potential to improve outcomes and pre-operative planning. LEVEL OF EVIDENCE III, case-control retrospective analysis.

Abstract
Objective The aim of this study was to identify the influence of a tourniquet on the blood loss, transfusion requirement, swelling, pain, knee function, range of motion (ROM), operation time, bone cement mantle thickness, and complications in patients operated with total knee arthroplasty (TKA). Methods Two authors independently retrieved PubMed, Embase, and CENTRAL to identify eligible randomized controlled trials (RCTs) evaluating the effectiveness of a tourniquet in TKA. Fixed- (I 2 < 50%) or random-effects (I 2 > 50%) models were selected to perform meta-analysis according to the value of I 2. Mean difference (MD) and risk ratio were selected as the effect sizes for continuous and dichotomous variables, respectively. Results A total of 29 RCTs, involving 2,512 operations (1,258 procedures with a tourniquet and 1,254 procedures without a tourniquet), were included, and 18 outcomes were compared. Tourniquet application could significantly decrease intraoperative blood loss (MD = -138.72 ml, p < 0.001), shorten operation duration (MD = -1.77 min, p < 0.001), and increase cement mantle thickness (MD = 0.17 mm, p < 0.001). However, it was significantly associated with increased postoperative pain intensity, decreased full ROM/flexion ROM/extension ROM, poorer knee function, increased knee swelling, and increased length of hospital stay (LOS) at several follow-up points (p < 0.050). No significant difference was found for postoperative draining volume, total blood loss, transfusion rate, change of Hb level, and risks of deep venous thrombosis and all complications. Conclusions Tourniquet application could only decrease the intraoperative blood loss but has no effectiveness on the total blood loss and transfusion requirement. On the contrary, it has a reverse effect on the pain score, knee function, ROM, swelling, and LOS.

Abstract
The use of tourniquet in total knee arthroplasty (TKA) had a lot of controversies with no clear agreement about the advantages and disadvantages of tourniquet. This study aims to show the effects of tourniquet use in TKA on the functional and clinical outcomes with follow-up of 5 years. This is a randomized, double-blind, and single-center study of 101 patients who were treated by TKA and divided randomly into two groups. Tourniquet was used in group A and was not used in group B. Both groups were assessed by Knee Society score (KSS), knee injury and osteoarthritis outcome score (KOOS), visual analogue scale (VAS) score for thigh pain, and postoperative complications. Both groups were followed up for 5 years. The group of no tourniquet showed significant better functional outcomes measured by KSS at postoperative periods of 2 weeks (p = 0.001), 6 weeks (p = 0.006), and 3 months (p = 0.034), and KOOS at postoperative periods of 2 weeks (p = 0.001), 6 weeks (p =0.001), and 3 months (p = 0.016). However, there was no significant difference in long-term follow-up of 5 years. There were significantly better results with use of tourniquet regarding surgeon's visualization during surgery, less operative time, and less calculated blood loss, while significantly better results with no use of tourniquet were reported regarding less hospital stay, less postoperative analgesic consumption, and less postoperative thigh pain measured by VAS score at postoperative periods of day 1 (p = 0.001), day 5 (p = 0.001), 2 weeks (p = 0.001), and 6 weeks (p = 0.001). Regarding postoperative blood transfusion and clinical deep venous thrombosis, there was no significant difference between use of tourniquet or not. The evidence presented in this level-1 randomized controlled trial suggests that no use of tourniquet in TKA can improve functional outcomes in early postoperative period with no significant difference on functional outcome at 5 years of follow-up.

Abstract
Maximizing hemostasis during total knee replacement procedures remains a key challenge in current practice. Bipolar sealer technology achieves intraoperative hemostasis through tissue sealing and coagulation with adjustable radio frequency energy and a saline-irrigated tip. Optimal surgical site hemostasis is important to avoid potential complications such as hemarthrosis, wound drainage, increased pain, delayed discharge, and readmissions. The aim of this study is to evaluate the safety and effectiveness of the bipolar sealer device in primary knee replacement in the largest consecutive series to date. A consecutive, treatment-control series of subjects who underwent a primary total knee arthroplasty (TKA) utilizing a bipolar sealer for hemostasis, one subgroup with concomitant tranexamic acid (TXA) administration (n = 1599) and one subgroup without TXA administration (n = 3582), compared with a control group of primary TKA under tourniquet only (n = 667). Statistical analyses were performed through two-tailed unpaired t-tests. There was less total postoperative drain output and a lower overall transfusion rate in the bipolar sealer group (807ml ± 428) (2.5%) than the tourniquet only group (1290 ± 658, p = 0.001) (8.4%, p = 0.0001), respectively. Drainage output in bipolar sealer + TXA (450 ± 297 ml) was lower than the other two groups (bipolar sealer 807 ± 428 mL, p = 0.0001; tourniquet only 1290 ± 658 ml, p = 0.0001). The bipolar sealer group had a higher hematocrit at postoperative day 1 (POD1) (bipolar sealer: 33.1 ± 4.3 cc, tourniquet only: 32.5 ± 4.3 cc, p = 0.001) and at discharge (POD2, bipolar sealer: 31.5 ± 3.7 cc, tourniquet only: 30.2 ± 3.9 cc, p = 0.0001). There were zero reported serious adverse events related to hemostasis management in any group. The bipolar sealer system is a safe and effective instrument to achieve intraoperative hemostasis during primary TKA. The bipolar sealer group required significantly fewer postoperative blood product transfusions and maintained a higher hematocrit concentration at the time of discharge compared with subjects treated solely with tourniquet mediated hemostasis. Addition of TXA to local hemostasis methods may further reduce blood loss and transfusion requirements. LEVEL OF EVIDENCE: This is a Level III study.

Abstract
Background: Infection rates after total ankle replacement (TAR) are known to be greater than those after hip or knee arthroplasty. Swelling after TAR can make wound healing more difficult, which can lead to infection. Tranexamic acid (TXA) has been shown to minimize blood loss after surgery, improving healing outcomes. We aim to assess the effect of TXA on blood loss and wound complications in TAR. Methods: The research looked retrospectively at patients who had TAR procedures between September 2014 and December 2019. The procedures were done using the anterior approach at a single hospital by two, foot and ankle surgeons. Tranexamic acid was given intraoperatively before the tourniquet was inflated. The surgeons did not use surgical drains. Pre and postoperative hemoglobin levels, outcome scores as well as post-operative complications were all documented. Results: A total of 69 patients were included in the study with 33 of them receiving TXA. With a mean age of 67.2, we had 31 females and 38 males. Tranexamic acid was given in doses ranging from 1 gm to 2 gm. None of the patients required blood transfusions after surgery, and there was no statistically significant difference in pre and postoperative hemoglobin levels between the two groups. In the TXA group, there were fewer wound complications. The TXA group achieved better results compared to the non-TXA group (p=0.0130). Conclusion: Tranexamic acid is safe and effective in lowering postoperative bleeding and preserving hemostasis after deflating the tourniquet, reducing edema and postoperative wound problems such as breakdown and dehiscence.

Abstract
Vitamin K is essential for the carboxylation of the vitamin K-dependent proteins that are responsible for the suppression of matrix calcification. The use of vitamin K antagonists (VKAs) in patients with cardiovascular diseases could affect protein carboxylation and lead to the development of osteoarthritis (OA). This review aims to summarise the current evidence for the relationship between VKAs and OA. The literature search revealed that in observation studies, good vitamin K status, as reflected by the circulating level or protein carboxylation status of vitamin K, is associated positively with improved joint structural and functional indices and negatively associated with OA incidence. By contrast, in limited retrospective and prospective studies, the use of VKAs is associated positively with OA occurrence and knee/hip replacement. Pharmacological interactions between VKAs and various OA therapeutic agents exist and require careful monitoring and dosing. In conclusion, further epidemiological studies are warranted to verify the relationship between VKA use and OA to strengthen the evidence. Given that VKA use exerts potentially negative effects on joint health, intervention is required to protect the quality of life and mobility of patients.

Abstract
BACKGROUND: Significant blood loss and requirement of allogenic blood transfusion during or after total knee replacement (TKR) have been reported. Incidence of blood transfusion in TKR is highly variable and depends on several factors. We investigated the blood utilization in patients undergoing TKR in our hospital and depicted the important risk factors that determine the need of allogenic blood transfusion in primary unilateral TKR. MATERIALS AND METHODS: The study included 1241 consecutive patients undergoing primary unilateral total knee arthroplasty. All the surgeries were performed by a single surgical team of orthopedists following standard procedure. Patient and disease details were obtained from patient file and hospital information system. Compatibility test was performed in blood bank before blood reservation following mandatory guidelines. Details of test, blood issue, and blood transfusion were documented in the blood bank. RESULTS: Of 1241 enrolled patients, 1069 (86.2%) were female. The median age of patients was 66 years with mean preoperative hemoglobin of 9.9 g/dL. Allogenic blood transfused was needed in 223 (17.9%) patients. Diabetes mellitus, hypertension, thyroid disorders, and chronic heart diseases were the major comorbid conditions. Risk factors such as gender, American Society of Anesthesiologists score, preoperative hemoglobin, and intraoperative and postoperative blood losses were significantly associated with blood transfusion. CONCLUSION: The risk factors determining blood transfusion in TKR vary between studies, however, all centers should establish standard operating procedures describing the surgical procedure and transfusion support in TKR. In addition, each center may develop specific blood management strategy to rationalize blood transfusion in TKR and overall successful care in TKR.

Abstract
The aim is to study whether a 3 day course of Tranexamic acid (TXA) is more effective in reducing blood loss following a TKR than a 1 day course. 250 patients were prospectively randomised into Group A (n=138; Perioperative and additional oral TXA for two days) and Group B (n=112; only perioperative TXA). Total Blood loss was calculated by the Haemoglobin (Hb) loss method at 4 days and compared in both groups using Mann Whitney test. The mean peri- operative blood loss in group A was 631.69 ± 264.99 ml as compared to 685.55 ± 239.033 ml in group B (p=0.0434). Use of TXA for 3 days following a TKR can be more effective in reducing blood loss.

Abstract
BACKGROUND Kinematic total knee arthroplasty (KA) is emerging as an alternative for conventional mechanically aligned (MA) total knee arthroplasty (TKA) for treating patients with osteoarthritis (OA) knee. Since its introduction, concerns remain about the reproducibility and outcomes in different ethnic groups. This study was undertaken to analyse patient-reported outcomes of kinematically aligned total knee arthroplasty using Oxford Knee Score (OKS) in Indian population. METHODS A total of 104 consecutive patients (75 females and 29 males) who underwent total knee arthroplasty between February 2016 and February 2018 were included in this prospective study. Only patients with primary OA knee were included, those with rheumatoid arthritis, previous knee surgery were excluded. All surgeries were done by a single surgeon using the same type of cruciate-retaining prosthesis (Vanguard, Zimmer Biomet, Indiana, United States) with the conventional instruments. The principles of kinematic knee alignment were followed. Preoperative and postoperative OKS were recorded. Secondary outcome variables such as Haemoglobin (Hb) drop and blood transfusion rate were noted. RESULTS The mean age of this group of patients was 65.28 years (range 54-83 years). 96 patients (108 knees) were available for final review. The average preoperative OKS was 15.71 whereas the average OKS at 2 years follow-up improved to 42.07. The mean Hb drop was 1.18 g/dl and none of the patients required blood transfusion. CONCLUSION This study demonstrates that kinematic alignment TKA provides excellent to good patient satisfaction in Indian population. There were no catastrophic failures in three years of follow-up in this series. The results of KA TKA were not compared to MA TKA in this study and our sample size is not big enough to make recommendations on routine use of this technique. Larger randomised trials in Indian patients are needed to propose solid recommendations. Our pilot data can be useful in calculating sample size for such studies.

Abstract
Background The prevalence of anaemia in patients planned for total hip and knee arthroplasty is about 20%. Optimising pre-operative haemoglobin levels by iron supplementation has been shown to decrease transfusion rates, complications and associated morbidity. The need for universal screening with iron studies of all elective arthroplasty patients is not clearly defined at present. Methods Retrospective review of 2 sequential cohorts of patients undergoing primary hip or knee arthroplasty by a single surgeon at a single centre between January 2013 and December 2017. The first group of patients underwent pre-operative iron studies only if found to be anaemic, with a haemoglobin below 12g/dl. From January 2015, all patients irrespective of the presence of anaemia were screened with a complete iron profile before surgery. Patients with a confirmed iron deficiency were administered with intravenous iron prior to surgery. The 2 cohorts were compared with regard to blood transfusion rate post-operatively and cost efficiency for universal screening with iron studies. Results There was a net decrease in the allogenic blood transfusion rate from 4.76 to 2.92% when universal iron studies were introduced but the difference was not statistically significant. Obtaining universal pre-operative iron studies is cost neutral with the price of allogenic blood transfusion in a similar cohort. We also diagnosed 5 patients with occult malignancies. Conclusions Universal screening with pre-operative iron studies and iron infusion in elective arthroplasty patients may reduce allogenic blood requirements and is cost neutral. An additional benefit is the potential to diagnose asymptomatic malignancies. Further studies are required to show the true benefit of universal pre-operative iron screening.

Efficacy and Safety of Intravenous Ferric Carboxymaltose in Patients with Postoperative Anemia Following Same-Day Bilateral Total Knee Arthroplasty: A Randomized Controlled Trial. J Clin Med 2021; 10:jcm10071457. [PMID: 33918110 PMCID: PMC8036569 DOI: 10.3390/jcm10071457] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Revised: 03/25/2021] [Accepted: 03/28/2021] [Indexed: 01/28/2023] Open
Abstract
(1) Background: The purpose of this study was to evaluate the efficacy and safety of intravenous (IV) ferric carboxymaltose (FCM) to treat acute postoperative anemia following same-day bilateral total knee arthroplasty (TKA). (2) Methods: A total of 118 patients who underwent same-day bilateral TKA were randomly assigned to two groups: an FCM group (FCM infusion, 58 patients) and a Control group (placebo with normal saline, 60 patients). The primary endpoint was the number of responders with a Hb increase of two or more points by the second postoperative week. The secondary endpoints were Hb level, iron metabolism variables and blood transfusion rate at 2, 6 and 12 weeks after surgery. (3) Results: The FCM group had more Hb responders than the Control group (62.1% vs. 31.6%, p < 0.001). The Hb level was significantly higher in the FCM group during 12 weeks after surgery (all p < 0.05). Ferritin, iron and transferrin saturation levels were significantly higher in the FCM group from 2 to 12 weeks postoperatively (all p < 0.05). There was no difference in transfusion rate after surgery (p > 0.05). (4) Conclusion: In patients with postoperative anemia after same-day bilateral TKA, IV FCM infusion significantly improved Hb response two weeks after surgery without severe adverse events compared to placebo. In contrast, transfusion rate and various parameters of quality of life assessment up to 12 weeks did not vary between these groups. Level of evidence: Level I.

Abstract
We present a literature review with technique for tourniquetless TKA for surgeons interested in transitioning away from the tourniquet. Tourniquet use provides a bloodless field and improved visualization with decreased intraoperative blood loss, but the arguments for tourniquet use of improved cement fixation and decreased overall blood loss have not been supported by the literature. Regarding recovery, tourniquetless TKA has demonstrated less postoperative pain and improved knee function. There is also the potential for patient harm with tourniquet use. The process of tourniquetless TKA begins preoperatively with anemia screening and treatment. Tranexamic acid decreases the overall blood loss and blood transfusion risk. We recommend preemptive analgesia. The surgery is performed with the knee flexed for a near bloodless field. For cementation, the knee irrigation removes lipids from the exposed bone along with meticulous cement technique. Tourniquetless TKA is able to be safely performed on a routine basis and brings potential benefits to the patient with no evident increased risk in comparison to tourniquet use.

Clinical and Budget Impact of Treating Preoperative Anemia in Major Orthopedic Surgery-A Retrospective Observational Study. J Arthroplasty 2020; 35:3084-3088. [PMID: 32654943 DOI: 10.1016/j.arth.2020.06.018] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2020] [Revised: 06/01/2020] [Accepted: 06/09/2020] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Preoperative anemia (POA) in elective surgery is associated with worse outcome. In this retrospective study, in elective hip and knee arthroplasties, the prevalence of POA and its associations with outcome were analyzed, followed by a model estimating the budget impact of screening and treatment of POA. METHODS All elective hip/knee arthroplasties performed during the period 2016-2018 were included. Patients with normal hemoglobin and patients with POA (hemoglobin < 13.0 g/dL in men and <12.0 g/dL in women) were compared. Outcome measures were allogeneic blood transfusion (ABT), length of stay (LOS), complications, mortality, and costs. The budget impact of screening for POA and treatment with intravenous iron when relevant was modeled based on the results of the costs related to POA. RESULTS In 881 procedures, the prevalence of POA was 21.5%. POA independently predicted increased risks of ABT (odds ratio [OR]adj, 9.5 [confidence interval-CI, 6.4-13.9]), prolonged LOS (ORadj, 2.8 [CI, 1.8-4.2]), and was associated with increased complications (ORadj, 1.9 [CI, 0.7-4.9]) and mortality (ORadj, 3.2 [CI, 0.8-13.5]). POA resulted in increased costs per patient (P < .001). The budget impact model showed a cost reduction of 254 euros per patient based on the assumption that patients screened and treated for iron-deficient anemia would have the same outcome as non-POA. CONCLUSION The prevalence of POA in elective orthopedic surgery in Sweden is at the same level as previously reported by others. Screening and treatment of POA would reduce costs based on less ABT and decreased LOS and may reduce complications in elective major orthopedic surgery.

Abstract
Objective To explore the hemostatic effect of intra‐articular administration of tranexamic acid (TXA) combined with knee flexion in total knee arthroplasty (TKA). Methods This randomized controlled trial was conducted at the Third Affiliated Hospital of Southern Medical University (Guangzhou, China) from January 2017 to February 2018. The patients were randomized 1:1 to the TXA group (TXA 500 mg into the joint after closure, knee, and hip flexed at 45° for 4 h) or the control group (physiological saline, with limb fully extended). The primary endpoint was postoperative hemoglobin reduction. The postoperative levels of hemoglobin were measured at four time points: 6 h after operation, and on the first, second, and third postoperative days. Calculated blood loss (CBL) at 3 days, transfusion rate, range of motion (ROM), VAS pain score, and knee circumference increment were the secondary endpoints. Ninety‐four (47/group) patients were analyzed. Results Postoperatively, there were statistically significant differences between the TXA and control groups in CBL (791 ± 212 mL vs 1175 ± 273 mL, P < 0.05). Hemoglobin reduction was significantly lower in the TXA group (2.0 ± 0.9 g/dL vs 4.5 ± 0.7 g/dL, P < 0.05). Based on the transfusion criteria, 3 out of 47 (6.4%) patients in the TXA group and 13 out of 47 (27.6%) patients in the control group received blood transfusions (P = 0.006). ROM (90.8° ± 6.2° vs 87.6° ± 6.4°, P = 0.004), VAS pain score (4.1 ± 1.1 vs 4.8 ± 1.3, P = 0.004), and KCI (2.4 ± 0.9 cm vs 3.2 ± 1.0 cm, P = 0.01) were better in the TXA group compared with thecontrols. There was no deep venous thrombosis (DVT), wound infection or other adverse events in either group. In the control group, 2 patients had a fever after blood transfusion. Conclusion Intra‐articular injection of TXA combined with knee and hip flexion at 45° can effectively attenuate CBL and hemoglobin reduction during primary TKA, without an additional adverse event.

Ann Med Surg (Lond) 2020; 55:180-184.

Abstract
Background Morbid obesity is a challenge in cases that require total knee arthroplasty, and several studies considered it a contraindication for the procedure due to associated risk of complications, including plummeting hemoglobin levels and subsequent need for a blood transfusion. This study investigated risk factors for blood transfusion in this patient group and considered their relationship to obesity. Materials and methods Patients' data were extracted from medical records, including estimated blood loss and perioperative hemoglobin levels. Patients were weighed and measured, and their body mass index (BMI) was calculated and stratified according to international criteria. Results A total of 188 patients were included in this study; among them, 136 patients had obesity (72%), with a mean BMI of 33.54. The mean volume of blood lost was 1055.4 ml, with the mean postoperative hemoglobin decrease of 1.42 g/dl and 2.88 g/dl at 6 and 24 h after surgery, respectively. The pre-operative Hb level was the only significant risk factor for blood transfusion. BMI did not affect the risk of blood transfusion or amount of blood lost. Conclusion Obesity (BMI > 30 kg/m2) did not increase the risk of needing a blood transfusion after total knee arthroplasty. A judicious transfusion strategy involving the pre-operative Hb optimization should be adopted in TKA to decrease transfusion rate, benefit patient outcomes, and increase healthcare system efficiency. This study shows that high BMI is not a risk factor for postoperative blood transfusion.

Abstract
OBJECTIVES This study aims to investigate the use of multiple blood management strategies and the effect of tourniquet on the estimated blood loss (EBL) in Jehovah's Witness (JW) patients who underwent primary total knee arthroplasty (TKA). PATIENTS AND METHODS Twenty-two self-reported JW patients (9 males, 13 females; mean age 66.8±8.6 years; range, 51 to 83 years) who underwent primary TKA between January 2014 and January 2020 in our institution were retrospectively reviewed. A standard blood management protocol that consisted of hypotensive anesthesia, local and systemic administration of tranexamic acid (TXA) and intraoperative cell salvage was applied to all patients. Patients were divided into two groups: with (n=11) and without (n=11) tourniquet use. The EBL was calculated according to Meunier's formula. Hemoglobin (Hgb), hematocrit (Hct), and EBL on the first and third postoperative days were compared statistically. RESULTS There was no significant difference between groups regarding postoperative Hgb (p=0.801 and p=0.767), Hct (p=0.617 and p=0.895), Hgb decline (p=0.311 and p=0.822), and EBL (p=0.067 and p=0.284) at first and third postoperative days. None of the patients required blood transfusion. No wound complication or symptomatic deep vein thrombosis was seen during the hospital stay. CONCLUSION Combined use of hypotensive anesthesia, intravenous administration of TXA, intraoperative periarticular injection, and cell salvage seem to be sufficient in controlling the blood loss in JW patients during TKA. Additional tourniquet use may not further decrease the EBL.

Abstract
Background During primary total knee arthroplasty (TKA), synovectomy as a part of the procedure has been recommended to relieve pain and inflammation of the synovium, but there is a controversy about it due to increased bleeding. In this meta-analysis, the aim is to answer whether synovectomy should be performed routinely during TKA for symptomatic knee osteoarthritis (KOA). Methods Relevant randomized controlled trials (RCTs) on synovectomy were retrieved through database searches of PubMed, Embase, Web of Science, and Cochrane Library up to February 2019. Studies that compared postoperative pain, clinical Knee Society Score (KSS), functional KSS, range of motion (ROM), drainage, pre- and postoperative hemoglobin difference, transfusion rate, operative time, and/or complications were included in the meta-analysis. Review Manager 5.3.0 was used for meta-analysis. Results We included 5 RCTs with 542 knees. Pooled results indicated that the synovectomy group was associated with more blood loss via drainage (WMD = − 99.41, 95% CI − 153.75 to − 45.08, P = 0.0003) and pre- and postoperative hemoglobin difference (WMD = − 0.93, 95% CI − 1.33 to − 0.5, P < 0.00001), compared with the non-synovectomy group. No statistically significant differences were demonstrated between both groups in postoperative pain, clinical KSS, functional KSS, ROM, transfusion rate, or complications (P > 0.05). Conclusions The current evidence demonstrates that performing synovectomy in primary TKA for symptomatic KOA does not have any clinical benefit. It increases postsurgical blood loss. Surgeons routinely undertaking synovectomy should deliberate whether this is clinically indicated and consider limiting resection, if possible.

Abstract
BACKGROUND/OBJECTIVE Despite effective therapies, rheumatoid arthritis (RA) can result in joint destruction requiring total joint arthroplasty to maintain patient function. An estimated 16% to 70% of those undergoing total joint arthroplasty of the hip or knee will receive a blood transfusion. Few studies have described risk factors for blood transfusion following total joint arthroplasty in patients with RA. The aim of this study was to identify demographic and clinical risk factors associated with receiving a blood transfusion following total joint arthroplasty among patients with RA. METHODS A retrospective study (n = 3270) was conducted using deidentified patient health claims information from a commercially insured, US data set (2007-2009). Data analysis included descriptive statistics and multivariate logistic regression. RESULTS Females were more likely to receive a blood transfusion (odds ratio [OR], 1.48; 95% confidence interval [CI], 1.16-1.87; p = 0.001). When compared with those in the South, patients residing the Midwest were less likely to receive a blood transfusion following total joint arthroplasty (OR, 0.56; 95% CI, 0.44-0.71). Relative to those receiving total knee arthroplasty, patients who underwent total hip arthroplasty were more likely to receive a blood transfusion (OR, 1.39; 95% CI, 1.14-1.70), and patients who underwent a total shoulder arthroplasty were less likely to receive a blood transfusion (OR, 0.14; 95% CI, 0.05-0.38; p < 0.001). Patients with a history of anemia were more likely to receive a blood transfusion compared with those who did not have this diagnosis (OR, 3.30; 95% CI, 2.62-4.14; p < 0.001). CONCLUSIONS Risk factors for the receipt of blood transfusions among RA patients who have undergone total joint arthroplasty were identified.

Abstract
Background Unexpected cardiac arrest in patients during surgery is associated with high mortality. Reasons are often multifactorial and unclear. Case presentation This case report describes a patient who developed reversible asystole during knee surgery under general anaesthesia. All diagnostic cardiac examinations were unremarkable. After surgery, the patient showed no further symptoms. Conclusion To prevent cardiac arrest due to non-cardiac reasons, patients with a high risk for asystole caused by vasovagal reflex or by pain need to be identified. Preoperative conditions such as hypovolemia need to be improved prior to surgery, and additional monitoring should be used. Further investigations to determine the influence of non-cardiac disease and long-term medication are necessary.

Abstract
BACKGROUND Postoperative hypothermia in elderly patients is a well-known serious complication as it impairs wound healing, induces coagulopathy, increases the risk of blood loss, enhances oxygen consumption, and precipitates cardiac arrhythmias. We conducted this randomized controlled trial to evaluate the effect of a forced-air warming system on rewarming elderly patients undergoing total knee or hip arthroplasty. METHODS We recruited 243 elderly patients undergoing total knee or hip arthroplasty between May and December 2016. They were divided into three groups according to a computer-generated randomization table: group C (n = 78, rewarmed with only a regular blanket), group F1 (n = 82, rewarmed with a forced-air warming system set at 38°C), and group F2 (n = 83, rewarmed with a forced-air warming system set at 42°C). The nasopharyngeal temperature was recorded every 5 min for the first half hour, then every 10 min up to the end of the PACU (postanesthesia care unit) stay. The primary outcome was the rewarming time. The rewarming rate, increase in nasopharyngeal temperature (compared to the start of rewarming), hemodynamics, recovery time, and incidences of adverse effects were recorded. RESULTS No significant differences were found among the three groups in terms of the baseline clinical characteristics, use of narcotic drugs, intraoperative temperature, and hemodynamics (P > .05). Compared with the elderly patients in groups C and F1, both the heart rate and mean arterial pressure of those in group F2 were significantly increased 20 min after arrival at the PACU (P < .05). Patients in group F2 had the shortest rewarming time (35.89 ± 6.45 min, P < .001), highest rewarming efficiency (0.028 ± 0.001°C/min, P < .001), and fastest increased nasopharyngeal temperature among the three groups. Moreover, the elderly patients in group F2 had lower incidences of arrhythmia and shivering (P < .05). CONCLUSIONS The use of a forced-air warming system set at 42°C was shown to be the most effective way of rewarming elderly patients with postoperative hypothermia.

Abstract
Current antifibrinolytics have decreased perioperative blood loss; however, some patients still require transfusions postoperatively. The authors sought to determine the risk factors associated with postoperative transfusions and to establish a "cutoff" preoperative hemoglobin threshold value specific to total knee arthroplasty (TKA) that would identify patients who would benefit from blood conservation programs. The institutional database was queried for primary TKA patients. Preoperative patient demographics and hemoglobin values were determined in addition to intraoperative and postoperative variables, including transfusion rate. Patients were stratified by whether they received a transfusion perioperatively, and risk factors were identified through univariable and multivariable analysis. Optimal cutoff values for hemoglobin were identified by concurrently maximizing the sensitivity and specificity for predicting the risk of a postoperative transfusion event. Men and women were analyzed independently. A total of 532 primary TKAs were included for analysis, and 33 patients (6.2%) required a transfusion. Advanced age (P=.019), low pre-operative hemoglobin value (P<.001), and failure to receive tranexamic acid (P<.001) were associated with increased risk of postoperative transfusion. A preoperative hemoglobin value of 12.5 g/dL was identified as the optimal cutoff for predicting postoperative transfusion requirements across all patients, with a sensitivity of 84.8% and a specificity of 76.4%. Preoperative anemia remains predictive of transfusion following TKA despite current antifibrinolytics. Patients with a preoperative hemoglobin value of less than 12.5 g/dL who are not receiving intravenous tranexamic acid are particularly at risk and should be considered for blood conservation programs.

Abstract
Total joint arthroplasty is associated with significant blood loss, that could result in the need of blood transfusions. Several techniques are being utilised to limit the volume of blood loss, in order to avoid transfusion. In this review, we look at blood loss in total joint arthroplasty and the perioperative strategies to limit the loss of blood. With the use of tranexamic acid gaining popularity, we analyse the published literature on its use in patients undergoing total joint arthroplasty. We have found that published studies favour using tranexamic acid in total joint arthroplasty as a safe and effective method of reducing blood loss.

Abstract
Objective Evaluate the efficacy of tranexamic acid in reducing bleeding in patients undergoing total knee arthroplasty. Methods 101 patients were randomized into two groups: the tranexamic acid group (n = 51) and the placebo group (n = 50). Patients were compared regarding the following parameters: reduction of hemoglobin, total estimated blood loss, drain output, and postoperative blood transfusion rate. Results Comparing the groups, there were statistically significant differences (p < 0.05) in the following parameters: reduction of hemoglobin, decreased hematocrit, estimated blood loss, and drain output. All values were lower in the tranexamic acid group. Only placebo group patients required blood transfusion. Conclusion The use of intravenous tranexamic acid is effective to reduce bleeding in patients undergoing total knee arthroplasty.

Abstract
INTRODUCTION Although total hip arthroplasty (THA) is an effective treatment for end-stage arthritis, it is also associated with substantial blood loss that may require allogeneic blood transfusion. However, these transfusions may increase the risk of certain complications. The purpose of our study is to evaluate: (i) the incidence/trends of allogeneic blood transfusion; (ii) the associated risk factors and adverse events; and (iii) the discharge disposition, length of stay (LOS), and costs for these patients between 2009 and 2013. METHODS The National Inpatient Sample database was used to identify 1,542,366 primary THAs performed between 2009 and 2013. Patients were stratified based on demographics, economic data, hospital characteristics, comorbidities, and whether or not allogeneic transfusion was received. Logistic regression was performed to evaluate the risk factors for transfusion and postoperative complications. RESULTS From 2009 to 2013, allogeneic transfusions were used in 16.9% of primary THAs, with a declining annual incidence. Except for obesity, all comorbidities were associated with increased likelihood of receiving a transfusion. Allogeneic transfusion patients were more likely to experience surgical site infections or pulmonary complications (p<0.001 for all). These patients were more likely to be discharged to a short-term care facility (p<0.001). Additionally, they had a greater mean LOS (p<0.001) and higher median hospital costs and charges when compared to their non-transfused counterparts. CONCLUSIONS While the observed decline in allogeneic transfusion usage is encouraging, further efforts should focus on preoperative patient optimisation. Given the projected increase in demand for primary THAs, orthopaedic surgeons must be familiar with safe and effective blood conservation protocols.

Abstract
BACKGROUND When critically analyzing our hospital system's rate of hypotension and acute kidney injury (AKI) after total joint arthroplasty, our incidence rates (14.54%, 6.02%) were much higher than our peers (7.17%, 2.03%) and national rates (2.0%, 3.3%). We present a multi-disciplinary management intervention that aimed to decrease overall complication rates. METHOD A multi-disciplinary team implemented a protocol at our suburban hospital to limit complication rates after joint replacement surgery. Hypotension, AKI, length of stay (LOS), re-admission rates, and mortality rates were compared before the protocol was implemented, after protocol implementation, and after protocol integration into our EMR (electronic medical record). RESULTS In total, 1233 patients over 36 months were followed. Hypotension rates after protocol implementation into EMR (group 3) were significantly lower than rates before the protocol (group 1) (P = .002), with rates after protocol implementation without EMR (group 2) trending toward a significant decrease from group 1 (P = .064). AKI rates in group 3 were significantly lower than group 1 (P = .000) and group 2 (P = .006). No difference was seen in hypotension rates between group 2 and 3 (P = .792) or AKI rates between group 1 and 2 (P = .533). Finally, no significant difference was seen between groups in LOS (P = .560), re-admission rates (P = .378), and mortality rates (all 0.0%). CONCLUSION By implementing a comprehensive electronic protocol consisting of pre-operative risk stratification, multi-disciplinary medical optimization, and an evolving post-operative management plan, significant decreases in hypotension and AKI can be seen.

Abstract
BACKGROUND Allogeneic transfusions are commonly used for substantial blood loss in total knee arthroplasty (TKA), but have been associated with adverse effects and increased costs. The purpose of this study is to provide a detailed description of (1) trends of allogeneic blood transfusion; (2) risk factors and adverse events; and (3) discharge disposition, length-of-stay (LOS), and cost/charge analysis for primary TKA patients who received an allogeneic blood transfusion from 2009-2013. METHODS A cohort of 3,217,056 primary TKA patients was identified from the National Inpatient Sample database from 2009-2013. Demographic, clinical, economic, and discharge data were analyzed for patients who received allogeneic blood products, and for those who did not receive any type of blood transfusion. Other parameters analyzed include risk factors, adverse events, discharge disposition, and costs/charges. RESULTS There was a significant decline in use of allogeneic transfusion from 2009-2013 incidence (13.9%-7.3%; P < .001). All comorbidities examined were associated with significantly increased risk of receiving allogeneic transfusion with exception of patients with AIDS, metastatic cancer, and peptic ulcer disease. Allogeneic transfusion was associated with worse outcomes during hospitalization. Patients also had a greater likelihood of discharge to short-term care, greater LOS, and greater median costs/charges. Among TKA patients who received an allogeneic transfusion, costs varied based on hospital ownership and characteristics, primary-payer, region, and bed-size. CONCLUSION Given the poor outcomes and higher costs associated with allogeneic transfusions, efforts must be undertaken to minimize this risky practice. With the projected increase in demand for TKAs, orthopedists must understand effective blood management strategies.

Influence of synovectomy on blood loss and need for transfusion in standard total knee replacement. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2018. [PMID: 29523973 DOI: 10.1007/s00590-018-2160-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 01/23/2023]
Abstract
BACKGROUND Synovial proliferation is a rather frequent intraoperative finding during the surgery of a total knee replacement. The aim of this study is to asses whether the standard procedure of a synovectomy results in changes in blood loss and in the need for transfusion in the immediate postoperative time after the total knee replacement. METHODS A prospective cohort study was performed with 120 patients undergoing total knee replacement (60 with synovectomy and 60 without it). Data on gender, age, and hemoglobin concentration prior to and after surgery were obtained. A bivariate and multivariate logistic regression analysis was performed. RESULTS The male gender as a protective factor [RR 0.25 (0.06-1.01)] and the low preoperative hemoglobin as a risk factor [RR 6.22 (2.48-15.58)] were significant in bivariate analysis. However, only the presence of low preoperative hemoglobin was shown to have an independent risk factor for the need for transfusion [RR 8.55 (2.77-26.45)]. CONCLUSION The practice of synovectomy showed no difference either in blood loss or in the number of transfusions. The findings of this study indicate that the practice of a synovectomy in a standard total knee replacement does not generate any benefit or prejudice as to the blood factor of the total knee arthroplasty.

Abstract
Background Blood loss during total knee arthroplasty (TKA) remains a concern, as many patients require blood transfusions, which increase risks of allergic reactions, disease transmission, and thromboembolisms. The purpose was to determine factors associated with blood loss and need for transfusion in patients receiving routine TKA. Methods The authors prospectively analyzed 150 consecutive uncemented TKAs for age, gender, body mass index (BMI), anticoagulant medication, type of anesthesia, tranexamic acid (TXA) administration, tourniquet inflation, drain placement, pre- and post-operative Haemoglobin (Hb) level (g/dL), and whether transfusion was necessary. Univariable and multivariable regression analyses were performed to identify factors associated with Hb loss and need for transfusion with significance level set at P value<0.05. Results The cohort comprised 92 women and 58 men, aged 69.5±8.9 years. The mean Hb loss was 3.7±1.3 g/dL. The 20 patients (13%) who had transfusions also had lower preoperative Hb (12.6±1.2 g/dL) compared to the remaining patients (14.3±1.2 g/dL). Hb loss was significantly associated with preoperative Hb, TXA, and gender, but multivariable regression identified gender as a confounder and indicated that TXA reduced Hb loss by 0.92 g/dL. Multivariable regression revealed the need for transfusion was only significantly associated with preoperative Hb and indicated that a decrease of preoperative Hb by 1 g/dL nearly quadrupled the chances of needing transfusion. Conclusions Hb loss was significantly associated with preoperative Hb levels and use of TXA, while the need for transfusion was only associated with preoperative Hb levels. These findings could help identify patients at risk for blood transfusions. Level of evidence: level III, prospective case series.

Abstract
PURPOSE OF REVIEW Outpatient total joint arthroplasty (OTJA) allows for a safe, cost effective pathway for appropriately selected patients. With current pressures on arthroplasty surgeons and their associated institutions to reduce costs per episode of care, it is important to define the steps and challenges associated with establishing an outpatient arthroplasty program. RECENT FINDINGS Several studies have outlined techniques of selecting patients suitable for this type of postoperative pathway. With emerging concerns about patients who undergo outpatient arthroplasty being at increased risk of medical complications, which may lessen projected cost savings, it is important to identify value-based strategies to optimize patient recovery after OTJA. This article reviews digital techniques for patient selection and data collection, operating room efficiency systems, and provides a summary of methods to build and maintain value in outpatient total joint replacement within the framework of bundled payment reimbursement.

Abstract
Background Studies on the use of tranexamic acid (TXA) to improve clinical outcomes after joint arthroplasty have reported contrasting results between intravenous (IV) TXA alone and combined IV and intraarticular (IA) administration. We compared the effectiveness of the 2 methods in providing higher postoperative hemoglobin (Hb) levels in patients undergoing primary total knee arthroplasty (TKA). Methods A total of 100 TKA patients were randomly assigned to receive either IV TXA alone (group 1) or combined IV and topical IA TXA (group 2). Hb and hematocrit levels were measured before and after surgery. The amount of drained blood and transfused blood for the 2 groups was compared. Results The Hb level was significantly higher at postoperative day 4, together with a positive, albeit not significant, trend toward less postoperative blood loss in the group that received combined IV and IA TXA. No postoperative infections or deep venous thrombosis events occurred. Conclusions This study reinforces evidence that, as compared to IV TXA alone, combined IV and IA administration of TXA has a synergic effect, leading to higher postoperative Hb levels without influencing drug safety in TKA patients.

Abstract
BACKGROUND Tranexamic acid (TXA) has been proven to be effective in reducing blood loss and transfusion rate after total knee arthroplasty (TKA) without increasing the risk of deep vein thrombosis (DVT) and pulmonary embolism (PE). Recently, an increasing number of studies have been interested in applying combined intravenous (IV) with intraarticular (IA) tranexamic acid in total knee arthroplasty. The purpose of this meta-analysis was to compare the blood loss and complications of combined TXA with IV TXA or IA TXA on TKA. METHODS Systematic search of literatures were conducted to identify related articles that were published in PubMed, MEDLINE, Embase, the Cochrane Library, SpringerLink, ClinicalTrials.gov, and Ovid from their inception to September 2016. All studies that compare blood loss and complications of combined TXA and IV TXA or IA TXA on TKA were included. Main outcomes were collected and analyzed by the Review Manager 5.3. RESULTS Five studies were included in the present meta-analysis. There was significant difference in total blood loss and blood volume of drainage when compared combined TXA group with IV TXA group or IA TXA group (P < 0.05). There was no difference in transfusion rate and thromboembolic complications when comparing combined TXA with IV TXA or IA TXA alone (P > 0.05). CONCLUSIONS Compared with administration of IA TXA or IV TXA alone on TKA, combined use of TXA has advantages in reducing total blood loss and blood volume of drainage without increasing the incidence of thromboembolic complications. We recommend combined TXA as the preferred option for patients undergoing TKA.
