Aslam F, Arshad HU, Qammar B, Shakeel I, Sidhu Z, Shakeel Z, Arbaz HM, Rashid T, Ishfaq MA, Zafar MN, Raza M. Comparison of Mean Postoperative Hemoglobin Concentrations in Patients Undergoing Total Knee Arthroplasty With Intravenous Versus Intraarticular Administration of Tranexamic Acid. Cureus 2024; 16:e68593. [PMID: 39371743 PMCID: PMC11450361 DOI: 10.7759/cureus.68593] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/02/2024] [Indexed: 10/08/2024] Open
Abstract
BACKGROUND Total knee arthroplasty (TKA) may result in significant blood loss, but it is an effective and affordable treatment for severe osteoarthritis in the knees. While intravenous (IV) tranexamic acid (TXA) is a commonly used technique, intraarticular (IA) TXA has just recently started to gain traction in joint replacement procedures. The purpose of this research was to examine the mean postoperative hemoglobin concentration in order to assess the effectiveness of TXA administered IV vs IA after TKA. OBJECTIVE To assess the effectiveness of intraarticular TXA against intravenous administration. MATERIALS AND METHODS The six-month randomized controlled experiment was started from October 5, 2022, to April 4, 2023, at "the Orthopedics Department of Sir Ganga Ram Hospital in Lahore". The experiment included 60 patients undergoing TKA, ranging in age from 30 to 70. All members of the surgical team, including the supervisor (a consultant surgeon), assistants, and researchers, were present throughout the surgery. A high, thigh tourniquet was employed in every case, and a medial parapatellar technique was performed as well. Before the tourniquet was inflated, individuals in the intravenous group received 1 g of TXA intravenously 15-30 minutes beforehand. In the IA group, the "patient received an injection of 2 g of TXA in a 20 mL solution" straight into the joint after the prosthesis was implanted and secured. Data were analyzed using SPSS (version 26), with numerical data (age, BMI, surgical length, and hemoglobin levels) presented as mean ± SD and categorical factors (gender, American Society of Anesthesiologists (ASA) class, anatomical side) shown as frequency and percentage. The mean postoperative hemoglobin levels were compared between groups using an independent sample t-test, with data stratified by various factors and p ≤ 0.05 considered significant. RESULTS There were 60 patients in this study, ranging in age from 30 to 70. The mean±SD age was 48.73±10.35 years. Patients' mean BMI was 25.51±4.48 kg/m², with representation across underweight, normal, overweight, and obese categories. The procedure took 173.10±32.61 minutes. The overall postoperative hemoglobin concentration was significantly higher in the IA TXA group (12.12±1.32 g/dL) compared to the IV TXA group (11.11±1.10 g/dL), with a p-value of 0.02. Additionally, when stratified by age, the IA TXA group consistently demonstrated higher postoperative hemoglobin levels across all age brackets, with significant differences observed in the 51-60 years (p = 0.001) and 61-70 years (p = 0.011) groups. Gender-based comparisons showed that IA TXA was associated with higher postoperative hemoglobin levels for both males (p < 0.05) and females (p < 0.05) compared to IV TXA. CONCLUSION This study demonstrates that IA administration of TXA is more effective in maintaining higher postoperative hemoglobin concentrations compared to IV TXA in patients undergoing TKA. The IA TXA group consistently achieved significantly higher hemoglobin levels across various age groups and both genders, indicating superior efficacy in reducing blood loss associated with TKA. These findings suggest that IA TXA could be a preferable alternative to IV TXA for enhancing postoperative hemoglobin recovery and potentially improving patient outcomes in knee arthroplasty procedures.

Abstract
BACKGROUND Revision total hip arthroplasty (rTHA) and revision total knee arthroplasty (rTKA) require considerable surgical proficiency, but are frequently delegated to the least experienced surgeons. This study examined the influence of surgeon experience on revision outcomes. METHODS Prospective data on confirmed aseptic rTHAs (n = 122) and rTKAs (n = 195) performed by 4 fellowship-trained surgeons in the same practice were retrospectively analyzed. Surgeons were grouped based on years in practice (inexperienced [IE] first 2 years, early experience [EE] 4 to 6 years, and senior experience [SE] 15 to 17 years). Procedure duration, estimated blood loss (EBL), and reoperation rates were compared, controlling for potential covariates. RESULTS Procedure durations varied based on surgeon experience for 3 of 4 rTHA diagnoses (P ≤ 0.001). Relative to the SE surgeon, procedure duration was 80.0 (95% confidence interval 61.7 to 98.4, P < 0.001) minutes longer for IE surgeons and 30.9 (95% confidence interval 17.5 to 44.3, P < 0.001) minutes longer for the EE surgeon. Procedure durations also varied based on surgeon experience for 3 of 4 rTKA diagnoses (P < 0.001), with the longest durations for IE surgeons. Procedure durations varied based on the interaction of surgeon experience, patient age, and body mass index. The EBL did not differ in rTHA based on surgeon experience (P = 0.978), but did differ for rTKA (P = 0.004). There were 25% of rTHAs performed by IE surgeons compared to 15.5% for the EE surgeon and 3.6% for the SE surgeon that underwent reoperation within a year of the index procedure (P = 0.064), with significantly more reoperations for the same indication among IE and EE surgeons (P = 0.046). CONCLUSIONS Complex procedures completed by less experienced surgeons may result in longer procedures, higher EBL, and more early reoperations. Study findings implicate a learning curve for revision arthroplasty that continues for several years, warranting consideration of existing patient allocation and referral patterns.

Medicine (Baltimore) 2024; 103:e38656. [PMID: 39093740 PMCID: PMC11296455 DOI: 10.1097/md.0000000000038656] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2024] [Accepted: 05/31/2024] [Indexed: 08/04/2024] Open
Abstract
Fascia iliaca compartment block (FICB) reduces opioid consumption and pain scores after total hip arthroplasty (THA), and has recently been widely applied. We investigated whether FICB could also reduce postoperative bleeding. One hundred and fifteen consecutive patients who underwent elective THA under general anesthesia over 5 months were retrospectively analyzed. They were divided into 2 groups: the FICB group received an epinephrine-mixed FICB procedure and the control group did not receive any block. Using the hematocrit measured at 4 different time points (preoperative and 1, 24, and 48 hours after surgery), the estimated blood loss (EBL) was calculated for 3 different time periods (0-1, 1-24, 24-48 hours after surgery). EBL at 1 to 24 hours (226 vs 398 mL, P = .008) was significantly lower in the FICB group than in the control group. Additionally, the number of packed red cell (PRC) units transfused per patient over 48 hours was 0.38 units in the FICB group, which was significantly lower than the 0.70 units used in the control group (P = .040). Epinephrine-mixed FICB in THA has the potential to reduce postoperative bleeding in the first 24 hours after surgery as well as reduce PRC transfusion requirements.

Abstract
BACKGROUND Von Willebrand disease (VWD) is the most common congenital bleeding disorder. This autosomal dominant condition arises from quantitative or qualitative defects of Von Willebrand factor. To our knowledge, this study leveraged a national database to characterize the largest VWD cohort of total hip arthroplasty (THA) patients to date, assessing 90-day postoperative adverse events and 5-year revision-free survival. METHODS Adult patients who underwent primary THA for osteoarthritis were identified from January 2010 to October 2021 in a nationwide database. Patients who had and did not have VWD were matched (4:1) on age, sex, and Elixhauser Comorbidity Index and compared with multivariable logistic regression. Patients were then categorized based upon venous thromboembolism (VTE) chemoprophylaxis prescription patterns to compare bleeding and thrombotic adverse events. RESULTS Of 544,851 THA patients, VWD was identified in 309 patients (0.06%). The matched cohorts contained 1,221 patients who did not have VWD and 306 patients who have VWD. On multivariable analysis, VWD patients had increased odds of 90-day VTE (odds ratio [OR] = 1.86) and hematoma (OR = 3.40) (P < .05 for all). No difference in 5-year revision-free survival was found. The VWD patients receiving aspirin or no prescriptions had greater odds of VTE (OR = 2.39, P = .048). Those on other chemoprophylaxis agents had greater odds of hematoma (OR = 4.84, P = .006). CONCLUSIONS Patients with VWD undergoing THA had increased odds of 90-day VTE if using aspirin or no prescriptions, or hematoma if using other chemoprophylaxis. There is a delicate balancing act of clotting versus bleeding that must be considered in managing such patients, but it was reassuring that no difference in overall 5-year revision-free survival was found.

Ir J Med Sci 2024; 193:1971-1976.

Abstract
INTRODUCTION Approximately 7000 total hip arthroplasty (THA) surgeries occur in Ireland each year. A number of preoperative factors have been identified that increase the risk of postoperative blood transfusion after THA, including anaemia. The ability to identify patients at risk may allow preoperative management strategies to reduce blood transfusions. Data from Irish orthopaedic patients is currently lacking. AIM To investigate if preoperative anaemia and other factors are associated with postoperative blood transfusions in patients who undergo THA. METHODS A retrospective cohort study of all patients who underwent THA in 2019 in SIVUH, Cork, using medical chart review. RESULTS In total, 350 charts met the inclusion criteria, with 291 charts reviewed. 8.9% of the patients who underwent THA had preoperative anaemia. Among these, 19.2% had a postoperative blood transfusion, compared to 1.5% of patients who were not anaemic preoperatively. The odds of receiving a blood transfusion was 15.5 times greater in the preoperative anaemia group compared to the non-anaemic group. Increasing age and higher ASA scores were associated with preoperative anaemia and postoperative blood transfusions. Length of stay was increased by 2.2 days (p < 0.00016) if blood transfusion was required. CONCLUSION Preoperative anaemia was common in an Irish orthopaedic population undergoing THA. Preoperative anaemia predisposes patients to the greatest increased risk of postoperative blood transfusions. The other factors associated with the need for postoperative transfusion were ASA grade 3 or more and age greater than 65 years. Patients who received postoperative blood transfusions had a significantly increased length of hospital stay.

Are Routine Postoperative Hemoglobin Tests Justified in All Patients Who Undergo Total Hip Arthroplasty Due to a Displaced Femoral Neck Fracture? J Clin Med 2024; 13:4371. [PMID: 39124638 PMCID: PMC11313077 DOI: 10.3390/jcm13154371] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2024] [Revised: 07/16/2024] [Accepted: 07/20/2024] [Indexed: 08/12/2024] Open
Abstract
Background: Total hip arthroplasty (THA) is a standard treatment for a displaced femoral neck fracture in the elderly. In contemporary healthcare, there is a global shift towards fast-track treatment modalities, prioritizing early hospital discharge for patients. Consequently, routine postoperative blood tests may become redundant, offering significant time and cost savings. We aim to evaluate postoperative hemoglobin levels in trauma-related THA cases and identify patient profiles for whom these tests hold significance. Methods: A retrospective review of 176 THA procedures performed between 2018 and 2022, focusing on individuals undergoing THA for displaced femoral neck fractures. Multivariable logistic regression analysis was employed to identify factors associated with postoperative hemoglobin levels below 8.5 g/dL. Results: Of the 176 patients included, 109 (61.9%) were women and the mean age was 69.09 ± 8.13 (range 27 to 90) years. The majority of the patients underwent surgery within 48 hours of admission. The mean preoperative hemoglobin (Hb) level was 13.1 ± 1.4 g/dL, while the mean postoperative Hb level was 10.5 ± 1.2 g/dL. Only six patients (3.41%) exhibited postoperative Hb levels of ≤8.5 g/dL. No significant associations were found between postoperative Hb levels ≤ 8.5 and any demographic, surgical, or medical characteristics. Conclusions: Our findings suggest that routine postoperative blood count testing may not be necessary for most patients undergoing THA for displaced femoral neck fractures, particularly those without complications or significant comorbidities.

Abstract
Aims Transfusion after primary total hip arthroplasty (THA) has become rare, and identification of causative factors allows preventive measures. The aim of this study was to determine patient-specific factors that increase the risk of needing a blood transfusion. Methods All patients who underwent elective THA were analyzed retrospectively in this single-centre study from 2020 to 2021. A total of 2,892 patients were included. Transfusion-related parameters were evaluated. A multiple logistic regression was performed to determine whether age, BMI, American Society of Anesthesiologists (ASA) grade, sex, or preoperative haemoglobin (Hb) could predict the need for transfusion within the examined patient population. Results The overall transfusion rate was 1.2%. Compared to the group of patients without blood transfusion, the transfused group was on average older (aged 73.8 years (SD 9.7) vs 68.6 years (SD 10.1); p = 0.020) and was mostly female (p = 0.003), but showed no significant differences in terms of BMI (28.3 kg/m2 (SD 5.9) vs 28.7 kg/m2 (SD 5.2); p = 0.720) or ASA grade (2.2 (SD 0.5) vs 2.1 (SD 0.4); p = 0.378). The regression model identified a cutoff Hb level of < 7.6 mmol/l (< 12.2 g/dl), aged > 73 years, and a BMI of 35.4 kg/m² or higher as the three most reliable predictors associated with postoperative transfusion in THA. Conclusion The possibility of transfusion is predictable based on preoperatively available parameters. The proposed thresholds for preoperative Hb level, age, and BMI can help identify patients and take preventive measures if necessary.

Abstract
BACKGROUND Modern surgical protocols, particularly the use of tranexamic acid (TXA), have reduced, but not eliminated, blood transfusions surrounding total hip arthroplasty (THA). Identifying patients at risk for transfusion remains important for risk reduction and to determine type and screen testing. METHODS We reviewed 6,405 patients who underwent primary, unilateral THA between January 2014 and January 2023 at a single academic institution, received TXA, and had preoperative hemoglobin (Hgb) values. We compared demographics, baseline Hgb levels, and surgical details between patients who were and were not transfused. Data were analyzed utilizing multivariate regression and receiver operating characteristic curve analysis. RESULTS The overall perioperative and intraoperative transfusion rates were 3.4 and 1.0%, respectively. Patients who were older, women, and American Society of Anesthesiologists class >II demonstrated an increased risk of transfusion. Risk of transfusion demonstrated an inverse correlation with preoperative Hgb levels, a bimodal association with body mass index, and a direct correlation with age, surgical time, and estimated blood loss on multivariate analysis. The receiver operating characteristic analysis demonstrated a preoperative Hgb cutoff of 12 g/dL for predicting any transfusion. Above the threshold of 12 g/dL, total and intraoperative transfusions were rare, with rates of 1.7 and 0.3%, respectively. Total and intraoperative transfusion rates with Hgb between 11 and 12 g/dL were 14.3 and 4.6%, respectively. Below 11 g/dL, total and intraoperative transfusion rates were 27.5 and 10.1%, respectively. CONCLUSIONS In the age of TXA, blood transfusion is rare in THA when preoperative Hgb is >12 g/dL, challenging the need for universal type and screening. Conversely, patients who have Hgb < 11.0 g/dL, remain at substantial risk for transfusion. Between Hgb 11 and 12 g/dL, patient age, sex, body mass index, American Society of Anesthesiologists classification, anticipated estimated blood loss, and surgical time may help predict transfusion risk and the need for a perioperative type and screen.

Abstract
Background/Objectives: Blood loss can be a serious complication in patients undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA). Various methods are used by surgeons to achieve hemostatic control in these patients. Complications are associated with perioperative blood loss. In this systematic review, we examined the efficacy of using bone wax to control bleeding in patients undergoing THA and TKA. Methods: The PRISMA model was used to systematically identify and aggregate articles for this study. The PubMed and EMBASE databases were used to search individual studies that examined the use of bone wax in THA or TKA. After applying the search term "bone wax", 2478 articles were initially identified. After inclusion and exclusion criteria were applied, three articles were aggregated for this systematic review. Results: The use of bone wax in THA and TKA decreased blood loss in patients undergoing these operations. Postoperative blood loss following surgery was lower in the bone wax groups compared to the control groups as well. Patients in the bone wax groups also required fewer blood transfusions than those who did not receive bone wax. Conclusions: Bone wax appears to be another modality that can be used by physicians to maintain hemostatic control in THA or TKA patients. Reduced blood loss and transfusion rates in surgery can increase patient outcomes. More studies are needed to examine the efficacy of bone wax in comparison with other hemostatic tools.

Abstract
BACKGROUND In Germany, current revision rates after arthroplasty range between 28-37%. In particular, remaining cement residues are causative for additional revision surgery after periprosthetic joint infection, which is why complete cement removal is of high importance. However, the removal of remaining cement residues often confronts the surgeon with technical challenges. Complication-free and complete cement removal requires extensive preoperative preparation in order to develop the best possible surgical strategy. TREATMENT Special instrument sets to facilitate cement removal in revision cases are available from various manufacturers. In addition to endoluminal approaches, access enhancements such as extended osteotomies exist to facilitate complete cement removal. Finally, the surgeon should be able to give the indication for an intraoperative procedural change after a defined time interval.

Abstract
Historically, total hip arthroplasty (THA) and total knee arthroplasty (TKA) have been associated with significant perioperative blood loss and a relatively high rate of allogeneic blood transfusions. However, in recent years, tranexamic acid (TXA), a competitive inhibitor of tissue plasminogen activator, inhibiting fibrinolysis of existing thrombi, has substantially decreased the need for blood transfusion in THA and TKA. Various administration strategies have been studied, but there remains a lack of consensus on an optimal route and dosing regimen, with intravenous and topical regimens being widely used. A growing body of literature has demonstrated the safety and efficacy of TXA in primary and revision THA and TKA to reduce blood loss, allogeneic transfusions, and complications; it is associated with lowered lengths of stay, costs, and readmission rates.

Allogeneic Blood Transfusion and Risk of Postoperative Complications in Patients with Mild and Moderate Anemia of Any Cause? A Retrospective Cohort Study in Total Revision Hip Surgery. Transfus Med Hemother 2024; 51:12-21. [PMID: 38314244 PMCID: PMC10836862 DOI: 10.1159/000530135] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Accepted: 02/26/2023] [Indexed: 02/06/2024] Open
Abstract
Introduction Patients undergoing revision total hip surgery (RTHS) have a high prevalence of mild and moderate preoperative anemia, associated with adverse outcomes. The aim of this study was to investigate the association of perioperative allogeneic blood transfusions (ABT) and postoperative complications in preoperatively mild compared to moderate anemic patients undergoing RTHS who did not receive a diagnostic anemia workup and treatment before surgery. Methods We included 1,765 patients between 2007 and 2019 at a university hospital. Patients were categorized according to their severity of anemia using the WHO criteria of mild, moderate, and severe anemia in the first Hb level of the case. Patients were grouped as having received no ABT, 1-2 units of ABT, or more than 2 units of ABT. Need for intraoperative ABT was assessed in accordance with institutional standards. Primary endpoint was the compound incidence of postoperative complications. Secondary outcomes included major/minor complications and length of hospital and ICU stay. Results Of the 1,765 patients, 31.0% were anemic of any cause before surgery. Transfusion rates were 81% in anemic patients and 41.2% in nonanemic patients. The adjusted risks for compound postoperative complication were significantly higher in patients with moderate anemia (OR 4.88, 95% CI: 1.54-13.15, p = 0.003) but not for patients with mild anemia (OR 1.93, 95% CI: 0.85-3.94, p < 0.090). Perioperative ABT was associated with significantly higher risks for complications in nonanemic patients and showed an increased risk for complications in all anemic patients. In RTHS, perioperative ABT as a treatment for moderate preoperative anemia of any cause was associated with a negative compound effect on postoperative complications, compared to anemia or ABT alone. Discussion ABT is associated with adverse outcomes of patients with moderate preoperative anemia before RTHS. For this reason, medical treatment of moderate preoperative anemia may be considered.

Abstract
BACKGROUND With the restoration of the natural hip biomechanics, a successful total hip arthroplasty (THA) and long-term survival is pursued. Although robotic THA (rTHA) has been developed to increase accuracy of implant positioning, leg lengths and offsets, discussions about its radiological and clinical advantages over conventional THA (cTHA) continues. OBJECTIVE The aim of this study was to compare clinical and radiological outcomes of robotic and conventional THA. METHODS This retrospective study compares functional and radiological outcomes of 82 rTHA with a matched group of 82 cTHA in terms of age, sex, body mass index and preoperative functional scores. The minimum follow up was 12 months for all patients. Functional outcomes were Harris Hip Score (HHS) and the Western Ontario and McMaster University Osteoarthritis index (WOMAC) evaluated pre- and postoperatively. Radiological evaluations included position of cup placement according to Lewinnek and Callanan safe zones, Canal Fill Ratio (CFR), Leg Length Discrepancy (LLD), Lateral offset (LO) and Femoral Component Alignment (FCA). Complications were also evaluated. RESULTS In the rTHA group, 91.5% (75 out of 82) of the acetabular cups were positioned within the safe zone whereas it was 63.4% (52 out of 82) for the cTHA group (p< 0.001). According to Callanan, they were 84.1% and 50%, respectively (p< 0.001). Between the groups, no statistically significant difference was found in CFR, LLD, HO, FCA, AI, AA, WOMAC, HHS and major complication rates. CONCLUSION rTHA is superior to cTHA in terms of accuracy and reproducibility of the cup placement, however no apparent clinical benefit was found in short term follow.

Abstract
BACKGROUND Previous research has shown that underweight patients may be at a greater risk of experiencing postsurgical complications. The purpose of this study was to investigate the association between body mass index (BMI) and postoperative complications following single-level anterior lumbar fusion (ALF). METHODS All single-level elective ALF procedures performed between 2010 and 2020 were identified in the PearlDiver Mariner Database. Patients were separated into 6 groups based on the World Health Organization BMI classifications. Differences in postsurgical complications (ie, deep vein thrombosis, pulmonary embolism, surgical site infection, hardware malfunction, wound dehiscence, and blood transfusion) among BMI categories were assessed using a χ2 contingency test. RESULTS Results indicated that underweight patients (BMI <20) were at a significantly greater risk of developing deep vein thromboses, experiencing hardware malfunction, and requiring blood transfusion compared with any other BMI classification (P < 0.001). Results also demonstrated that underweight individuals had similar risks of developing surgical site infection and wound dehiscence compared with patients classified as having obesity class III. CONCLUSION Underweight patients may be at a greater risk than currently believed of experiencing postoperative complications following single-level ALF procedures. CLINICAL RELEVANCE Patients with a BMI of 20 or less should be carefully evaluated prior to surgical intervention to ensure they are optimized for surgery. LEVEL OF EVIDENCE: 3

Abstract
Background While previous studies have investigated the association between bleeding disorders and outcomes with hip or knee surgeries, no studies have investigated the association between bleeding disorders and outcomes in upper extremity surgery. Questions/Purposes The purpose of this study was to investigate if a past history of bleeding disorders is associated with which, if any postoperative complications for patients receiving distal radius fracture open reduction internal fixation. Patients and Methods Patients undergoing operative treatment for distal radius fracture from 2007 to 2018 were identified in the National Surgical Quality Improvement Program database. Patients were stratified into two cohorts: patients with a bleeding disorder and patients without a bleeding disorder. In this analysis, 30-day postoperative complications were assessed, as well as mortality, extended length of stay, reoperation, and readmission. Bivariate and multivariate analyses were performed. Results Of the 16,489 total patients undergoing operative treatment for distal radius fracture, 16,047 patients (97.3%) did not have a bleeding disorder, whereas 442 (2.7%) had a bleeding disorder. Following adjustment on multivariate analyses, an increased risk of postoperative transfusion requirement (odds ratio [OR] 17.437; p = 0.001), extended length of hospital stay more than 3 days (OR 1.564; p = 0.038), and readmission (OR 2.515; p < 0.001) were seen in patients with a bleeding disorder compared to those without a bleeding disorder. Conclusion History of bleeding disorders is an independent risk factor for transfusions, extended length of stay, and readmission. We recommend a multidisciplinary team approach to addressing bleeding disorders before patients receive distal radius fracture open reduction internal fixation. Level of Evidence Level III, retrospective study.

Abstract
INTRODUCTION Total hip arthroplasty (THA) is a successful surgery, but despite the advancements in anesthesiology and orthopedics, sometimes blood transfusions are required to manage the anemia due to the blood loss, involving a substantial number of patients. The aim of this retrospective comparative study is to define how the choice of the surgical approach, either direct anterior (DA) or posterolateral (PL), may influence the postoperative blood loss and the need for transfusion in THA. MATERIALS AND METHODS Data collection was carried out retrospectively of THAs performed between 2016 and 2021 on primary hip osteoarthritis treated by DA or with PL approach. Clinical and perioperative anesthetic data were collected. Preoperative hemoglobin levels were compared with the lowest detected level by calculating ΔHb (hemoglobin decrease). Then, data from the two groups were cross-checked: duration of surgery, whether premedication with tranexamic acid, duration of the hospitalization, rate of need for hemotransfusions, and amount of blood transfused. The two samples were subdivided into subgroups according to age, BMI, tranexamic acid prophylaxis, and chronic treatment with drugs that alter coagulative properties. RESULTS Time of surgery was longer for patients treated with DA access (mean DA: 78.8 min; mean PL: 74.8 min; p: 0.05; 95% CI), but the length of hospitalization was shorter for patients treated with DA group with a mean time of 6.23 days versus 7.12 days for the PL group (p < 0.01). DA THA resulted advantageous mainly in patients between 66 and 75 years, showing a reduced postoperative transfusion requirement in the postoperative period (DA: 13.43%-mean: 1.33 units; PL: 26.82%-mean: 1.18 units; p: 0.044, 95% CI). Patients that assume blood-altering drugs showed a higher transfusion rate (p < 0.01), but comparison of the two subgroups showed that the choice of the surgical approach did not significantly affect the transfusion rate in these patients (p: 0.512). Prophylaxis with tranexamic acid reduced the transfusion rate (p < 0.01). CONCLUSION Patients treated by minimally invasive direct anterior approach undergo a significantly shorter hospitalization. From the analysis of patient's subgroups those aged between 66- and 75-years benefit from the DA approach mainly for the minor blood loss with less frequent transfusion requirement.

Abstract
Importance The optimal pharmacologic thromboprophylaxis agent after total hip and total knee arthroplasty is uncertain and consensus is lacking. Quantifying the risk of postoperative venous thromboembolism (VTE) and bleeding and evaluating comparative effectiveness and safety of the thromboprophylaxis strategies can inform care. Objective To quantify risk factors for postoperative VTE and bleeding and compare patient outcomes among pharmacological thromboprophylaxis agents used after total hip and knee arthroplasty. Design, Setting, and Participants This retrospective cohort study used data from a large health care claims database. Participants included patients in the United States with hip or knee arthroplasty and continuous insurance enrollment 3 months prior to and following their surgical procedure. Patients were excluded if they received anticoagulation before surgery, received no postsurgical pharmacological thromboprophylaxis, or had multiple postsurgery thromboprophylactic agents. In a propensity-matched analysis, patients receiving a direct oral anticoagulant (DOAC) were matched with those receiving aspirin. Exposures Aspirin, apixaban, rivaroxaban, enoxaparin, or warfarin. Main Outcomes and Measures The primary outcome was 30-day cumulative incidence of postdischarge VTE. Other outcomes included postdischarge bleeding. Results Among 29 264 patients included in the final cohort, 17 040 (58.2%) were female, 27 897 (95.2%) had inpatient admissions with median (IQR) length of stay of 2 (1-2) days, 10 948 (37.4%) underwent total hip arthroplasty, 18 316 (62.6%) underwent total knee arthroplasty; and median (IQR) age was 59 (55-63) years. At 30 days, cumulative incidence of VTE was 1.19% (95% CI, 1.06%-1.32%) and cumulative incidence of bleeding was 3.43% (95% CI, 3.22%-3.64%). In the multivariate analysis, leading risk factors associated with increased VTE risk included prior VTE history (odds ratio [OR], 5.94 [95% CI, 4.29-8.24]), a hereditary hypercoagulable state (OR, 2.64 [95% CI, 1.32-5.28]), knee arthroplasty (OR, 1.65 [95% CI, 1.29-2.10]), and male sex (OR, 1.34 [95% CI, 1.08-1.67]). In a propensity-matched cohort of 7844 DOAC-aspirin pairs, there was no significant difference in the risk of VTE in the first 30 days after the surgical procedure (OR, 1.14 [95% CI, 0.82-1.59]), but postoperative bleeding was more frequent in patients receiving DOACs (OR, 1.36 [95% CI, 1.13-1.62]). Conclusions and Relevance In this cohort study of patients who underwent total hip or total knee arthroplasty, underlying patient risk factors, but not choice of aspirin or DOAC, were associated with postsurgical VTE. Postoperative bleeding rates were lower in patients prescribed aspirin. These results suggest that thromboprophylaxis strategies should be patient-centric and tailored to individual risk of thrombosis and bleeding.

Abstract
BACKGROUND Little scientific evidence exists on blood loss and transfusion rates depending on the fixation technique. The hypothesis of this study was that the blood loss and transfusion rate are lower in cemented and hybrid total hip arthroplasty (THA) compared to cementless THA. METHODS We retrospectively compared a total of 1500 patients who received either cementless, cemented, hybrid or reverse hybrid THA. All patients underwent THA in 2021 at a single orthopedic center in Germany. RESULTS The lowest blood loss was found in patients who received a fully cemented THA (695 ± 74 ml). Hybrid THA with a cemented stem showed a blood loss of 845 ± 30 ml and reverse hybrid THA showed the highest blood loss with an average of 994 ± 74 ml. Cementless THA caused an average blood loss of 957 ± 16 ml. There was a significant difference between cementless THA, hybrid THA (cemented stem), and fully cemented THA (p < 0.05). Transfusion rates ranged from 1.3% (cementless THA) to 7.9% (cemented THA) between the groups with a transfusion rate of 2.5% overall. CONCLUSION We found significantly lower blood loss in cemented THA and hybrid THA compared to cementless THA. Although blood loss was lower in cemented and hybrid THA, this did not result in lower transfusion rates. This could be due to other confounders such as age, comorbidities, and preoperative anemia.

Abstract
BACKGROUND To determine the incidence and identify the predisposing factors for allogeneic blood transfusion (ABT) in patients with rheumatoid arthritis (RA) undergoing primary unilateral total knee arthroplasty (TKA). METHODS A total of 702 patients with RA who underwent primary unilateral TKA between 2003 and 2022 at a single center, were retrospectively enrolled. Patients were stratified into the ABT and non-ABT groups. Data on patient demographics, laboratory parameters, and disease- and surgery-related parameters were collected from chart reviews and compared between the ABT and non-ABT groups. Multivariate logistic regression analysis was conducted to identify the possible factors associated with postoperative ABT. RESULTS A total of 173 (24.6%) patients underwent ABT after surgery. Significant risk factors for ABT included the degree of flexion contracture [odds ratio (OR) = 1.018, P = 0.005] and thickness of insertion (OR = 1.170, P = 0.014). Conversely, body mass index (OR = 0.937, P = 0.018), preoperative hemoglobin level (OR = 0.973, P < 0.001), and intraoperative use of tranexamic acid (TXA) (OR = 0.119, P < 0.001) were associated with a lower risk of ABT in TKA. CONCLUSION We identified the significant risk and protective factors for ABT during TKA in patients with RA. This information could be helpful in optimizing perioperative blood management strategies during these surgeries.

Abstract
Background As the aging population increases, osteoporotic neck of femur fracture cases will continue to rise. Although hemiarthroplasty or half hip replacement is the treatment of choice in a majority of patients, a small but definite cohort of patients would need a total hip replacement. In these elderly patients who often have comorbidities, the use of cement to fix the prosthesis is often quoted as beneficial in view of perceived lower blood loss compared to uncemented fixation of the prosthesis. However, the cementation of the implant in itself has inherent problems. This study examined three modalities of fixation of a prosthesis for total hip replacement in the neck of femur fractures, namely, cemented, hybrid, and uncemented, and compared their relative intraoperative blood loss. Methodology This is a retrospective study with a follow-up of two years. Patients who presented to a level 1 trauma center in an inner city metropolitan with neck of femur fractures and were treated by total hip replacement were included in the study. Intraoperative blood loss was calculated using Nadler's formula. Results There was no statistical difference in intraoperative blood loss in either of the three groups of patients, namely, cemented, hybrid, or uncemented total hip replacement for neck of femur fractures. Conclusions Intraoperative blood loss should not influence the modality of prosthesis fixation for total hip replacement in neck of femur fractures.

Abstract
Background and Objectives: Short-stem total hip arthroplasty has become increasingly popular in recent years. While many studies have shown excellent clinical and radiological results, very little is known about the learning curve for short-stem total hip arthroplasty through an anterolateral approach. Therefore, the aim of this study was to determine the learning curve for short-stem total hip arthroplasty among five residents in training. Materials and Methods: We performed retrospective data analysis of the first 30 cases of five randomly selected residents (n = 150 cases) with no experience before the index surgery. All patients were comparable, and several surgical parameters and radiological outcomes were analyzed. Results: The only surgical parameter with a significant improvement was the surgical time (p = 0.025). The changes in other surgical parameters and radiological outcomes showed no significant changes; only trends can be derived. As a result, the correlation between surgical time, blood loss, length of stay, and incision/suture time can also be seen. Only two of the five residents showed significant improvements in all examined surgical parameters. Conclusions: There are individual differences among the first 30 cases of the five residents. Some improved their surgical skills faster than others. It could be assumed that they assimilated their surgical skills after more surgeries. A further study with more than 30 cases of the five surgeons could provide more information on that assumption.

Abstract
PURPOSE The main challenges in revision total hip arthroplasty (rTHA) are the treatment of the bone loss and the pre-operative planning. 3D-printed models may enhance pre-operative planning. The aim of the study is to compare the intra- and peri-operative results and costs for Paprosky type 3 rTHAs planned with 3D-printed models to ones accomplished with the conventional imaging techniques (X-rays and CT scan). METHODS Seventy-two patients with Paprosky type 3 defect underwent rTHA between 2014 and 2021. Fifty-two patients were treated with standard planning and 20 were planned on 3D-printed models. Surgical time, intra-operative blood loss, number of transfused blood units, number of post-operative days of hospitalization, and use of acetabular rings were compared between the two groups. A costs comparison was also performed. RESULTS The 3D-printed group showed reduced operative time (101.8 min (SD 27.7) vs. 146.1 min (SD 49.5), p < 0.001) and total days of hospitalization (9.3 days (SD 3.01) vs. 12.3 days (SD 6.01), p = 0.009). The cost of the procedures was significantly lower than the control group, with an adjusted difference of 4183 euros (p = 0.004). No significant differences were found for the number of total transfused blood units and blood loss and the number of acetabular rings. CONCLUSION The use of 3D-printed models led to a meaningful cost saving. The 3D-printed pre-operative planning for complex rTHAs seems to be effective in reducing operating time, hospital stay and overall costs.

Plasma Fibrinogen as a Predictor of Perioperative-Blood-Component Transfusion in Major-Nontraumatic-Orthopedic-Surgery Patients: A Cohort Study. Diagnostics (Basel) 2023; 13:diagnostics13050976.

Abstract
There is a trend towards increased perioperative bleeding in patients with plasma fibrinogen levels < 200 mg/dL-1. This study aimed to assess whether there is an association between preoperative fibrinogen levels and perioperative blood-product transfusion up to 48 h after major orthopedic surgery. This cohort study included 195 patients who underwent primary or revision hip arthroplasty for nontraumatic etiologies. Plasma fibrinogen, blood count, coagulation tests, and platelet count were measured preoperatively. A plasma fibrinogen level of 200 mg/dL-1 was the cutoff value used to predict blood transfusion. The mean (SD) plasma fibrinogen level was 325 (83) mg/dL-1. Only thirteen patients had levels < 200 mg/dL-1, and only one of them received a blood transfusion, with an absolute risk of 7.69% (1/13; 95%CI: 1.37-33.31%). Preoperative plasma fibrinogen levels were not associated with the need for blood transfusion (p = 0.745). The sensitivity and the positive predictive value of plasma fibrinogen < 200 mg/dL-1 as a predictor of blood transfusion were 4.17% (95%CI: 0.11-21.12%) and 7.69% (95%CI: 1.12-37.99%), respectively. Test accuracy was 82.05% (95%CI: 75.93-87.17%), but positive and negative likelihood ratios were poor. Therefore, preoperative plasma fibrinogen level in hip-arthroplasty patients was not associated with the need for blood-product transfusion.

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
PURPOSE Total hip arthroplasty (THA) in patients with rheumatoid arthritis (RA) has been associated with an increased risk of periprosthetic joint infection, periprosthetic fractures, dislocations, and post-operative blood transfusion. However, higher post-operative blood transfusion is unclear whether it reflects peri-operative blood loss or is characteristic of RA. This study aimed to compare the complications, allogenic blood transfusion, albumin use, and peri-operative blood loss between patients who underwent THA because of RA or osteoarthritis (OA). METHODS Patients undergoing cementless THA for hip RA (n = 220) or hip OA (n = 261) at our hospital between 2011 and 2021 were retrospectively enrolled. Deep vein thrombosis, pulmonary embolism, myocardial infarction, calf muscular venous thrombosis, wound complications, deep prosthetic infection, hip prosthesis dislocation, periprosthetic fractures, 30-day mortality, 90-day readmission, allogeneic blood transfusion, and albumin infusions were considered as primary outcomes, while secondary outcomes included the number of perioperative anaemia patients as well as total, intra-operative, and hidden blood loss. RESULTS Compared to the OA group, patients with hip RA showed significantly higher rates of wound aseptic complications, hip prosthesis dislocation, homologous transfusion, and albumin use. RA patients also showed a significantly higher prevalence of pre-operative anemia. However, no significant differences were observed between the two groups in total, intra-operative, or hidden blood loss. CONCLUSIONS Our study suggests that RA patients undergoing THA are at a higher risk of wound aseptic complications and hip prosthesis dislocation than patients with hip OA. Pre-operative anaemia and hypoalbuminaemia in patients with hip RA place them at a significantly higher risk of post-operative blood transfusion and use of albumin.

Abstract
BACKGROUND Patients who have Paget's Disease more frequently require total hip arthroplasty (THA) and total knee arthroplasty (TKA) than matched controls. However, controversy remains regarding their outcome. We aimed to evaluate the literature regarding outcomes following THA and TKA in patients who have Paget's Disease. METHODS MEDLINE, EMBASE and Cochrane databases were searched for all articles evaluating outcomes following THA and TKA in patients who have Paget's Disease. Quality of included studies was assessed using the Newcastle-Ottawa Scale. RESULTS A total of 19 articles (published between 1976 and 2022) were included, comprising 58,695 patients (48,766 controls and 10,018 patients who have Pagets Disease), from 209 potentially relevant titles. Patients with Paget's Disease have a pooled mortality of 32.5% at a mean of 7.8 years (range, 0.1 to 20) following THA and 31.0% at a mean of 8.5 years (range, 2 to 20) following TKA, with a pooled revision rate of 4.4% at 7.2 years (range, 0 to 20) following THA and 2.2% at 7.4 years (range, 2 to 20) following TKA. Renal and respiratory complications, as well as heterotopic ossification and surgical-site infection were the most common post-operative complications. CONCLUSION There is marked heterogeneity in outcome reporting of studies assessing arthroplasty in patients who have Paget's Disease, with studies of low to moderate quality. Patients with Paget's Disease undergoing THA and TKA appear to have similar implant longevity as their unaffected counterparts. However, they appear to have an increased risk of medical and surgical complications and may have a higher mortality risk from their procedure.

Abstract
BACKGROUND The transfusion rate is relatively high in patients with ankylosing spondylitis (AS) undergoing total hip arthroplasty (THA). However, relevant studies focusing on the predisposing factors for transfusion with a large sample size are lacking. This study aimed to investigate the incidence of and risk factors for allogeneic blood transfusion in patients with AS undergoing primary unilateral THA. METHODS This retrospective study included 331 patients with AS who underwent primary unilateral THA between 2011 and 2021. Relevant parameters were collected through a chart review. Multivariate logistic regression analysis was conducted to identify possible factors associated with perioperative allogeneic blood transfusion. RESULTS A total of 113 (34.1%) patients received perioperative allogeneic blood transfusions. Factors related to receiving an allogeneic blood transfusion included prolonged operative duration (odds ratio [OR] per 10 min = 1.139, P = 0.047), increased estimated intraoperative blood loss (OR per 100 mL = 1.348, P < 0.001), and increased postoperative drainage volume (OR per 100 mL = 1.235, P = 0.024). A higher body mass index (BMI) (OR = 0.914, P = 0.012), perioperative tranexamic acid (TXA) use (OR = 0.166, P < 0.001), and a higher preoperative hemoglobin level (OR per 1 g/dL = 0.744, P = 0.004) decreased the risk of transfusion. CONCLUSIONS In patients with AS undergoing THA, prolonged operative duration, increased estimated intraoperative blood loss, and increased postoperative drainage volume were found to be risk factors for transfusion, whereas a higher BMI, perioperative TXA use, and a higher preoperative hemoglobin level were protective factors. These results may aid in developing a better perioperative management strategy, ultimately reducing the need for transfusion.

Abstract
INTRODUCTION Robotic-arm assisted unicompartmental knee arthroplasty (RA-UKA) has demonstrated accurate component positioning and excellent outcomes for medial components. However, there is a paucity of literature on lateral compartment RA-UKA. The purpose of our study was to assess the midterm clinical outcomes and survivorship of lateral RA-UKA. METHODS This study was a retrospective review of a single-center prospectively maintained cohort of 33 patients (36 knees) indicated for lateral UKA. Perioperative, and postoperative two- and five-year Knee injury Osteoarthritis Outcome Score (KOOS), Western Ontario and McMaster Universities Osteoarthritis Score (WOMAC), and Forgotten Joint Score (FJS) patient reported outcome measures were collected. Five-year follow-up was recorded in 29 patients (32 knees). RESULTS Mean follow up was 5.1 ± 0.1 years. Mean age and BMI was 70.9 ± 7.2 years and 29.0 ± 4.2 kg/m2, respectively. At discharge, mean distance walked was 273.4 ± 70.4 feet, and mean pain score was 2.0 ± 2.5. At 2-year follow up, mean KOOS, WOMAC, and FJS were 75.1 ± 13.5, 15.0 ± 7.2, and 81.0 ± 23.3, respectively. At 5-year follow up, mean KOOS, WOMAC, and FJS were 75.3 ± 14.6, 14.9 ± 5.0, and 75.8 ± 27.4, respectively. Mean change in KOOS and WOMAC were 35.6 ± 27.1 and 11.7 ± 13.4 (p< .001 and p< .001). 94% of patients were very satisfied/satisfied, 3% neutral, and 3% dissatisfied. 91% met activity expectations, and 59% were more active than before. Survivorship was 100% at 5 years. DISCUSSION In this study, lateral RA-UKA demonstrated significantly improved clinical outcomes, high patient satisfaction, met expectations, and excellent functional recovery at midterm follow up. Comparative studies are needed to determine differences between robotic-assisted and conventional lateral UKA, as well as TKA.

Abstract
Perioperative management for patients undergoing shoulder arthroplasty has evolved significantly over the years to reduce overt complications and improve patient outcomes. The groundwork for perioperative care encompasses initial patient selection and education strategies for achieving successful outcome. Multimodal pain management strategies have advanced patient care with the increased use of new regional/local anesthetics. In addition, complications resulting from blood loss and transfusions have been curtailed with the use of synthetic antifibrinolytic agents. It remains critical for shoulder arthroplasty surgeons to optimize patients during the perioperative period through various modalities to maximize functional progression, outcomes, and patient's satisfaction following shoulder arthroplasty.

Acute Postoperative Anemia After Unilateral Primary Total Joint Arthroplasty: Restrictive Transfusion Thresholds are Safe for Discharge Regardless of Delta Hemoglobin. J Arthroplasty 2022; 37:1737-1742.e2. [PMID: 35483607 DOI: 10.1016/j.arth.2022.04.021] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2022] [Revised: 03/12/2022] [Accepted: 04/16/2022] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Primary unilateral total joint arthroplasty (TJA) is associated with acute postoperative anemia that may require blood transfusion. Clinicians may worry about discharging patients after surgery who experience substantial decreases in hemoglobin (Hgb), even if their Hgb is above restrictive transfusion thresholds. The purpose of this study was to determine whether differences between preoperative and postoperative Hgb values (Delta) correlate with 90-day readmission in patients who did not receive perioperative transfusions. METHODS A retrospective review of patients undergoing primary unilateral TJA between 2015 and 2020 was performed. The primary outcome was whether a specific cutoff delta Hgb was predictive of readmission within 90 days due to anemia-related causes. Secondary outcomes included the presence of acute postoperative anemia and transfusion during readmission. RESULTS Six thousand seven hundred and ninety one patients had a median delta Hgb of 2.80. In total, 268 patients (3.95%) were readmitted within 90 days postoperatively, with two patients requiring transfusion during readmission. A significantly higher rate of readmission was found in patients with cardiovascular disease (5.16% versus 3.68%; P = .020). When constructing receiver operating characteristic curves, a cutoff value of 3.20 resulted in an area under curve of 0.595 (0.486-0.704). In patients with cardiovascular disease, a cutoff value of 3.10 resulted in an area under curve of 0.626 (0.466-0.787). CONCLUSION The magnitude of Hgb change was not predictive of anemia-related readmission within 90 days in patients who did not receive a perioperative transfusion. Patients experiencing higher delta Hgb values but remaining above the transfusion threshold may have a greater physiologic reserve.

Abstract
Background Surgical procedures impose hemostatic risk to people with hemophilia, which may be minimized by optimal factor (F) replacement therapy. Methods This analysis evaluates the efficacy and safety of extended half-life factor replacement recombinant FVIII and FIX Fc fusion proteins (rFVIIIFc and rFIXFc) during surgery in phase 3 pivotal (A-LONG/Kids A-LONG and B-LONG/Kids B-LONG) and extension (ASPIRE and B-YOND) studies. Dosing regimens were determined by investigators. Injection frequency, dosing, blood loss, transfusions, and hemostatic response were assessed. Results Forty-five major (n = 31 subjects) and 90 minor (n = 70 subjects) procedures were performed in hemophilia A; 35 major (n = 22) and 62 minor (n = 37) procedures were performed in hemophilia B. Unilateral knee arthroplasty was the most common major orthopedic procedure (hemophilia A: n = 15/34; hemophilia B: n = 8/24). On the day of surgery, median total dose in adults/adolescents was 81 IU/kg for rFVIIIFc and 144 IU/kg for rFIXFc; most major procedures required ≤2 injections (including loading dose). Through days 1-14, most major procedures had ≤1 injection/day. Hemostasis was rated excellent (rFVIIIFc: n = 39/42; rFIXFc: n = 29/33) or good (n = 3/42; n = 4/33) in evaluable major surgeries, with blood loss comparable with subjects without hemophilia. Most minor procedures in adults/adolescents required one injection on the day of surgery, including median loading dose of 51 IU/kg (rFVIIIFc) and 80 IU/kg (rFIXFc). No major treatment-related safety concerns were identified. No subjects developed inhibitors or serious vascular thromboembolic events. Conclusions rFVIIIFc and rFIXFc were efficacious and well tolerated for the management of perioperative hemostasis across a wide spectrum of major and minor surgeries in hemophilia.

Abstract
BACKGROUND Although many authors have discussed total blood loss after arthroplasty of the knee, hip, and shoulder, reports on perioperative blood loss after total ankle arthroplasty (TAA) are rare. The purpose of this study was to assess total blood loss after TAA and to identify correlated factors. METHODS A total of 103 cases (99 patients) of TAA for end-stage ankle osteoarthritis were enrolled in this study. Perioperative total blood loss was divided into intraoperative and postoperative blood loss. The patient-related variables evaluated for total blood loss were age, sex, body mass index, American Society of Anesthesiologists Classification score, comorbidities, history of previous ankle surgery, preoperative use of anticoagulants, platelet count and prothrombin time/international normalized ratio. Operation-related variables including type of anesthesia, operation time, TAA implant, and procedures performed in addition to TAA (if any) were evaluated to analyze correlations with total blood loss. In addition, the rate of transfusions after surgery was identified, and risk factors for transfusion were statistically analyzed. RESULTS The total blood loss was mean 795.5±351.1mL, which included 462.2±248.5mL of intraoperative blood loss and 333.2±228.6mL of postoperative blood loss. Sex, TAA implant, and additional bony procedures performed along with TAA were significantly correlated with total blood loss (p=0.039, 0.024, 0.024, respectively) but the other variables were not significant (p>0.05). Transfusions were administered for 4 cases (3.8%) but no risk factors for transfusion could be identified. CONCLUSION The total blood loss after TAA was 795.5mL and the rate of transfusions was 3.8%. This study demonstrated that male sex, use of TAA implants with a larger cutting surface, and bony procedures performed in addition to TAA were associated with an increase in total blood loss after TAA. The findings of this study will help surgeons to better predict blood loss and make optimal surgical plans accordingly. LEVEL OF EVIDENCE Level IV, retrospective case series.

The impact of surgical trainee involvement in total hip arthroplasty: a systematic review of surgical efficacy, patient safety, and outcomes. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2022; 33:1365-1409. [PMID: 35662374 DOI: 10.1007/s00590-022-03290-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/06/2022] [Accepted: 05/05/2022] [Indexed: 10/18/2022]
Abstract
PURPOSE Concerns persist that trainee participation in surgical procedures may compromise patient care and potentiate adverse events and costs. We aimed to analyse the potential impact and consequences of surgical trainee involvement in total hip arthroplasty (THA) procedures in terms of surgical efficacy, patient safety, and functional outcomes. METHODS We systematically reviewed Medline/PubMed, EMBASE, the Cochrane library, and Scopus databases in October 2021. Eligible studies reported a direct comparison between THA cases performed with and without trainee involvement. RESULTS Eighteen publications met our eligibility criteria and were included in our study. The included studies reported on 142,450 THAs completed on 142,417 patients. Specifically, 48,155 and 94,295 surgeries were completed with and without trainee involvement, respectively. The mean operative times for procedures with (n = 5,662) and without (n = 14,763) trainee involvement were 106.20 and 91.41 min, respectively. Mean overall complication rates were 6.43% and 5.93% for THAs performed with (n = 4842) and without (n = 12,731) trainees. Lastly, the mean Harris Hip Scores (HHS) for THAs performed with (n = 442) and without (n = 750) trainee participation were 89.61 and 86.97, respectively. CONCLUSION Our systematic review confirmed previous studies' reports of increased operative time for THA cases with trainee involvement. However, based on the overall similar complication rates and functional hip scores obtained, patients should be reassured concerning the relative safety of trainee involvement in THA. Future prospective studies with higher levels of evidence are still needed to reinforce the existing evidence.

Abstract
Purpose While unicompartmental knee arthroplasty (UKA) has demonstrated benefits over total knee arthroplasty (TKA) in selected populations, component placement continues to be challenging with conventional surgical instruments, resulting in higher early failure rates. Robotic-arm-assisted UKA (RA-UKA) has shown to be successful in component positioning through preop planning and intraop adjustability. The purpose of this study is to assess the 5-year clinical outcomes of medial RA-UKA. Methods This study was a retrospective review of a single-center prospectively maintained cohort of 133 patients (146 knees) indicated for medial UKA from 2009 to 2013. Perioperative data and 2- and 5-year Knee injury Osteoarthritis Outcome Score (KOOS), Western Ontario and McMaster Universities Osteoarthritis Score (WOMAC), and Forgotten Joint Score (FJS) outcome measures were collected. Five-year follow-up was recorded in 119 patients (131 knees). Results Mean follow-up was 5.1 ± 0.2 years. Mean age and BMI were 68.0 ± 8.1 years and 29.3 ± 4.7 kg/m2, respectively. At 2-year follow-up, mean KOOS, WOMAC, and FJS were 71.5 ± 15.3, 14.3 ± 7.9, and 79.1 ± 25.8, respectively. At 5-year follow-up, mean KOOS, WOMAC, and FJS were 71.6 ± 15.2, 14.2 ± 7.9, and 80.9 ± 25.1, respectively. Mean change in KOOS and WOMAC was 34.6 ± 21.4 and 11.0 ± 13.6, respectively (p < 0.001 and p < 0.001). For patient satisfaction at last follow-up, 89% of patients were very satisfied/satisfied and 5% were dissatisfied. For patient activity expectations at last follow-up, 85% met activity expectations, 52% were more active than before, 25% have the same level of activity, 23% were less active than before, and 89% were walking without support. All patients returned to driving after surgery at a mean 15.2 ± 9.4 days. Survivorship was 95% (95% CI 0.91-0.98) at 5 years. One knee (1%) had a patellofemoral revision, two knees (1.3%) were revised to different partial knee replacements, and five knees (3.4%) were converted to TKA. Conclusion Overall, medial RA-UKA demonstrated improved patient-recorded outcomes, high patient satisfaction, met expectations, and excellent functional recovery. Midterm survivorship was excellent. Longitudinal follow-up is needed to evaluate long-term outcomes of robotic-arm-assisted UKA procedures.

Abstract
BACKGROUND Despite a plethora of literature reporting on the use of tranexamic acid (TXA) in total hip arthroplasty (THA), little is available on its effect on post-operative hidden blood loss and even less on its use in the direct anterior approach (DAA), which is gaining popularity. MATERIALS AND METHODS This study was designed as a prospective, double blind, single centre, randomized controlled trial. Sixty patients were allocated to intravenous administration of 1.5 g of TXA just before wound closure while 60 patients were allocated to topical application of 3.0 g of TXA via a subfascial drain at the end of the procedure. Post-operative blood loss was (1) calculated via a well-established formula based on pre- and post-operative Hb levels, patients characteristics and intra-operative blood loss and (2) measured via the amount that collected in the subfascial drain over time. RESULTS No statistical significant difference in post-operative blood loss was found, neither when the formula was used (0.55 L [topical] vs 0.67 L [IV]; p = .140) nor when looking at the drain output (0.25 L [topical] vs 0.29 L [IV]; p = .108). No significant difference in secondary outcome measures, such as transfusion of units of packed red blood cells, length of hospital stay or the occurrence of venous thromboembolisms, could be found either. CONCLUSIONS This study provides detailed insights into the intra- and post-operative blood loss in DAA THA and shows that topical and IV TXA have similar effects on hidden blood loss. Clinical Trial Number: NCT01940692. LEVEL OF EVIDENCE I Level I-Randomized Controlled Trial.

Effect of an Elevated Preoperative International Normalized Ratio on Transfusion and Complications in Primary Total Hip Arthroplasty with the Enhanced Recovery after Surgery Protocol. Orthop Surg 2021; 14:18-26. [PMID: 34825494 PMCID: PMC8755872 DOI: 10.1111/os.13176] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2021] [Revised: 10/16/2021] [Accepted: 10/20/2021] [Indexed: 02/05/2023] Open
Abstract
Objective To verify whether an elevated preoperative international normalized ratio (INR) increases transfusion and complications independently in primary total hip arthroplasty (THA) with the management of an enhanced recovery after surgery (EARS) protocol. Methods We retrospectively reviewed the database of adults who underwent primary THA between 2014 and 2018 by the same surgeon. A total of 552 patients were assigned into three groups by preoperative INR class: INR ≤ 0.9, 0.9 < INR < 1.0, and INR ≥ 1.0. We regarded transfusion within 90 days during the same hospitalization as the primary outcome. We also included perioperative blood loss, maximum Hb drop, postoperative anaemia requiring medicine, and length of hospital stay (LOS) during the same hospitalization in the study. Complications and reoperation at 90 days and mortality at 90 days and 12 months were also included in the study. Univariable analyses were utilized to compare baselines and outcomes among the three groups. Multivariate logistic regressions were used to adjust for differences at baseline among the groups. Results All patients had an INR < 1.5 preoperatively and were managed with the ERAS protocol. Among them, 93 (16.8%) patients had INR ≤ 0.9, 268 (48.6%) patients had 0.9 < INR < 1.0, and 191 (34.6%) patients had INR ≥ 1.0. In the univariable analyses, as the INR increased, the transfusion rates increased from 1.08% for INR ≤ 0.9, to 1.12% for 0.9 < INR < 1.0 and to 5.76% for INR ≥ 1.0 (P < 0.05). The overall complication rate increased from 10.8% for INR ≤ 0.9, to 16.4% for 0.9 < INR < 1.0, and to 22.5% for INR ≥ 1.0 (P < 0.05). The length of stay (LOS) in the INR ≥ 1.0 group was 5.7 ± 2.2 days, which was significantly longer than that in the INR ≤ 0.9 group (4.7 ± 1.6 days, P = 0.000) and 0.9 < INR < 1.0 group (5.1 ± 2.0 days, P = 0.007). No statistical significance was detected among the groups regarding blood loss, maximum Hb drop, or the incidence of postoperative anaemia that required medicine. There was no significant difference in reoperation or mortality among the groups. When controlling for demographic and comorbidity characteristics, there was no statistically significant difference in the odds of transfusion during the same hospitalization or overall complications at 90 days among the groups (P > 0.05). Conclusions Elevated preoperative INR cannot increase transfusion or complication rates independently in primary THA with the management of the ERAS protocol. With the improvement in the ERAS protocol and the use of tranexamic acid (TXA), an INR < 1.5 is still a conventional safe threshold for THA surgery.

Abstract
BACKGROUND Blood conservation and reduction in the need for allogeneic blood transfusion (ABT) has been a subject of importance in total hip arthroplasty. There are a number of well-recognized parameters that influence blood loss during total hip arthroplasty (THA). The role of surgical approach on blood loss and the rate of ABT during THA is not well studied. The hypothesis of this study was that blood loss and the need for ABT is lower with direct anterior (DA) approach. METHODS In a case-control retrospective cohort study, we analyzed 1,524 primary THAs performed at a single institution by seven fellowship-trained surgeons between January 2015 to March 2017. All patients received THA using either the modified direct lateral (DL) or direct anterior (DA) approach using a standard operating table. The overall ABT rate was 10.2% (155/1,524) in the cohort. Demographic, surgical, and postoperative data were extracted and analyzed. Logistic regression was used to identify independent risk factors for transfusion. RESULTS Higher preoperative hemoglobin (p<0.001), use of DA approach (p<0.016) and administration of tranexamic acid TXA, (p=0.024) were identified as independent factors which reduced the odds of ABT. Operative time (p<0.001) was associated with an increased odd of ABT, while age, BMI and type of anesthesia were not statistically significant. CONCLUSION Based on the findings of this study, direct anterior approach for THA appears to be protective against blood loss and reduced ABT rate, when controlling for confounding variables.

Abstract
Objective
To collect data on the role played by tranexamic acid in the prevention and management of blood loss in patients undergoing total hip arthroplasty and total knee arthroplasty.
Methods
In the present prospective, comparative study, 30 patients undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA) were randomly allocated into 1 of 2 groups with 15 patients each. Tranexamic acid was administered by intravenous and topical routes in the study group, but it was not administered in the control group. Preoperative blood parameters, intraoperative and postoperative blood loss, and need for blood transfusion were noted. Statistical analysis was performed using the chi-squared test and the independent
t
-test.
Results
The study group had statistically significant higher postoperative hemoglobin values (
p
= 0.03), less difference between pre and postoperative hemoglobin value (
p
= 0.046), less difference between pre and postoperative packed-cell volume (
p
= 0.06), less intraoperative measured blood loss (
p
= 0.015), and less volume of blood collected in the drain (
p
= 0.0291) compared with the control group. There was also reduced frequency of blood transfusions in the study group (
p
= 0.0008).
Conclusion
Tranexamic acid is associated with reduced intra and postoperative blood loss and reduced frequency of blood transfusions in patients undergoing THA/TKA.

Abstract
Aims Orthopaedic surgeries are complex, frequently performed procedures associated with significant haemorrhage and perioperative blood transfusion. Given refinements in surgical techniques and changes to transfusion practices, we aim to describe contemporary transfusion practices in orthopaedic surgery in order to inform perioperative planning and blood banking requirements. Methods We performed a retrospective cohort study of adult patients who underwent orthopaedic surgery at four Canadian hospitals between 2014 and 2016. We studied all patients admitted to hospital for nonarthroscopic joint surgeries, amputations, and fracture surgeries. For each surgery and surgical subgroup, we characterized the proportion of patients who received red blood cell (RBC) transfusion, the mean/median number of RBC units transfused, and exposure to platelets and plasma. Results Of the 14,584 included patients, the most commonly performed surgeries were knee arthroplasty (24.8%), hip arthroplasty (24.6%), and hip fracture surgery (17.4%). A total of 10.3% of patients received RBC transfusion; the proportion of patients receiving RBC transfusions varied widely based on the surgical subgroup (0.0% to 33.1%). Primary knee arthroplasty and hip arthroplasty, the two most common surgeries, were associated with in-hospital transfusion frequencies of 2.8% and 4.5%, respectively. RBC transfusion occurred in 25.0% of hip fracture surgeries, accounting for the greatest total number of RBC units transfused in our cohort (38.0% of all transfused RBC units). Platelet and plasma transfusions were uncommon. Conclusion Orthopaedic surgeries were associated with variable rates of transfusion. The rate of RBC transfusion is highly dependent on the surgery type. Identifying surgeries with the highest transfusion rates, and further evaluation of factors that contribute to transfusion in identified at-risk populations, can serve to inform perioperative planning and blood bank requirements, and facilitate pre-emptive transfusion mitigation strategies.

Lack of Cost-Effectiveness of Preoperative Erythropoiesis-Stimulating Agents and/or Iron Therapy in Anaemic, Elective Surgery Patients: A Systematic Review and Updated Analysis. PHARMACOECONOMICS 2021; 39:1123-1139.

Abstract
OBJECTIVES For anaemic elective surgery patients, current clinical practice guidelines weakly recommend the routine use of iron, but not erythrocyte-stimulating agents (ESAs), except for short-acting ESAs in major orthopaedic surgery. This recommendation is, however, not based on any cost-effectiveness studies. The aim of this research was to (1) systematically review the literature regarding cost effectiveness of preoperative iron and/or ESAs in anaemic, elective surgery patients and (2) update existing economic evaluations (EEs) with recent data. METHODS Eight databases and registries were searched for EEs and randomized controlled trials (RCTs) reporting cost-effectiveness data on November 11, 2020. Data were extracted, narratively synthesized and critically appraised using the Philips reporting checklist. Pre-existing full EEs were updated with effectiveness data from a recent systematic review and current cost data. Incremental cost-effectiveness ratios were expressed as cost per (quality-adjusted) life-year [(QA)LY] gained. RESULTS Only five studies (4 EEs and 1 RCT) were included, one on intravenous iron and four on ESAs + oral iron. The EE on intravenous iron only had an in-hospital time horizon. Therefore, cost effectiveness of preoperative iron remains uncertain. The three EEs on ESAs had a lifetime time horizon, but reported cost per (QA)LY gained of 20-65 million (GBP or CAD). Updating these analyses with current data confirmed ESAs to have a cost per (QA)LY gained of 3.5-120 million (GBP or CAD). CONCLUSIONS Cost effectiveness of preoperative iron is unproven, whereas routine preoperative ESA therapy cannot be considered cost effective in elective surgery, based on the limited available data. Future guidelines should reflect these findings.

Abstract
➤ As a result of the advances in surgical technique and implant design, total hip arthroplasty (THA) is increasingly offered for the management of osteoarthritis of the hip in patients with fragile or pathologic bone. ➤ Posttraumatic or congenital deformities associated with fragile or pathologic bone are frequently encountered and necessitate diligent preoperative planning. ➤ Surgeons should be prepared to evaluate and manage intraoperative iatrogenic fracture. ➤ While there is limited evidence to date, components made with computer-assisted design can be considered, given the unique and highly variable patient population.

Abstract
INTRODUCTION We hypothesised that a single preoperative intravenous dose of tranexamic acid (TXA) is effective in patients who undergo total hip arthroplasty (THA) and are at high risk of blood transfusion (preoperative haemoglobin level <13.0 g/dL). METHODS A prospective, randomised controlled study of 308 patients who underwent primary THA was conducted. 256 participants remained in the study and were divided into 2 major groups: high-risk group comprising 116 patients with preoperative Hb < 13.0 g/dL (57 of whom were treated with a 15 mg/kg intravenous bolus of TXA, and 59 of whom did not receive the medication) and low-risk group comprising 140 patients with Hb ⩾ 13.0 g/dL (71 of whom received the same dose of TXA, and 69 of whom did not). Participants were followed up at 3 weeks, 3 months, 6 months, and 1 year after surgery. RESULTS The use of TXA in both groups of patients significantly increased the levels of postoperative Hb and Ht. TXA protected high-risk patients from blood loss and from transfusion. In low-risk patients the use of TXA reduced blood loss but did not protect from blood transfusion. The median length of stay was significantly affected for high-risk patients. No thromboembolic event was recorded in either group. CONCLUSIONS TXA reduces intra- and postoperative bleeding, transfusion rates, and the length of hospital stays in patients with low preoperative Hb. The use of TXA in patients with normal preoperative Hb reduces blood loss but does not affect the transfusion rate.ClinicalTrials.gov Identifier: NCT03019198.

Abstract
The aim of the study was to investigate if preoperative blood flow velocity in femoral vein in different positions of the hip during total hip arthroplasty (THA) is a predictor of postoperative deep vein thrombosis (DVT). In patients undergoing THA, blood flow velocity and diameter of proximal femoral vein on THA side were measured preoperatively in four flexion positions of the hip. After THA, patients were followed up for 42 days for DVT occurrence, and clinical features of patients with and without postoperative DVT were compared. The mean blood flow velocity in maximal flexion (90º+) preoperatively was significantly lower in patients with postoperative DVT (19/103) compared to patients without it (8.4±2 cm/s vs. 10.6±2.3 cm/s; p<0.001). Using the receiver operating characteristic curve analysis, the cut-off value for blood flow velocity during maximal flexion was 8.24 cm/s. In addition, anesthesia duration, duration of surgical position of the patient, body mass index, amount of blood transfused after surgery, and clinical signs of DVT were markedly different between patients with and those without postoperative DVT. Blood flow velocity in femoral vein in maximal flexion of the hip (90º+) measured prior to THA is an independent predictor of postoperative DVT.

Abstract
The purpose of this study was to retrospectively evaluate the efficacy of a tranexamic acid (TXA) perioperative protocol for primary hip- and knee arthroplasty, in terms of allogenic blood transfusion rates. A retrospective cohort study was conducted and included all primary hip and knee arthroplasty procedures in the period of 2014-2019. Patients who underwent surgery due to trauma or revision were excluded. A total amount of 5205 patients were eligible for inclusion. Two equal and weight depending doses of TXA were given, preoperative as an oral dose and intravenously at wound closure. The primary outcome was blood transfusion rate. Further analysis on patient characteristics (e.g. age, gender), blood loss, perioperative haemoglobin (Hb) levels and complication/readmission rate was performed.
A total of 49 (0.9%) patients received perioperative allogenic blood transfusions. Mean age, distribution of gender, body-mass index, American Society of Anaesthesiologists score, duration of surgery, type of arthroplasty, estimated blood loss, perioperative Hb levels and length of stay were statistically significant different between transfused and not-transfused patients. The incidence of thromboembolic adverse events (e.g. deep vein thrombosis/lung embolism) was 0.5%. Low blood transfusion rate was found after implementation of a standardized perioperative TXA protocol for primary hip and knee arthroplasty.

Abstract
BACKGROUND Topical hemostatic agents are commonly used for reducing perioperative blood loss and transfusion requirement in primary total knee arthroplasty (TKA), although the optimal option has yet to be defined. This study aimed to evaluate the efficacy and safety of topical hemostatic agents and rank the best intervention using the network meta-analysis (NMA) method. METHODS We searched Web of science, PubMed, and Cochrane Library database up to April 2020, for randomized controlled trials (RCTs) on topical hemostatic agents in primary TKA. The quality of included studies was assessed using the Cochrane "risk of bias" tool. Direct and indirect comparisons were performed for the result of network meta-analysis followed by consistency test. RESULTS Thirty seven RCTs with 3792 patients were included in this NMA and the pooled results indicated that tranexamic acid plus diluted epinephrine (TXA+DEP) displayed the highest efficacy in reducing total blood loss, hemoglobin drop and transfusion requirement. None of the included treatments was found to increase risk of thromboembolic events compared to placebo. According to the results of ranking probabilities, TXA+DEP had the highest possibility to be the best topical hemostatic agent with regard to the greatest comparative efficacy and a relatively high safety level. CONCLUSION Current evidence supports that administration of TXA+DEP may be the optimal topical hemostatic agent to decrease blood loss and transfusion requirement in primary TKA. More direct studies that focused on the topical application of TXA+DEP versus other treatments are needed in the future.

Abstract
Endoprosthetic surgery can lead to relevant blood loss resulting in red blood cell (RBC) transfusions. This study aimed to identify risk factors for blood loss and RBC transfusion that enable the prediction of an individualized transfusion probability to guide preoperative RBC provision and blood saving programs. A retrospective analysis of patients who underwent primary hip or knee arthroplasty was performed. Risk factors for blood loss and transfusions were identified and transfusion probabilities computed. The number needed to treat (NNT) of a potential correction of preoperative anemia with iron substitution for the prevention of RBC transfusion was calculated. A total of 308 patients were included, of whom 12 (3.9%) received RBC transfusions. Factors influencing the maximum hemoglobin drop were the use of drain, tranexamic acid, duration of surgery, anticoagulation, BMI, ASA status and mechanical heart valves. In multivariate analysis, the use of a drain, low preoperative Hb and mechanical heart valves were predictors for RBC transfusions. The transfusion probability of patients with a hemoglobin of 9.0–10.0 g/dL, 10.0–11.0 g/dL, 11.0–12.0 g/dL and 12.0–13.0 g/dL was 100%, 33.3%, 10% and 5.6%, and the NNT 1.5, 4.3, 22.7 and 17.3, while it was 100%, 50%, 25% and 14.3% with a NNT of 2.0, 4.0, 9.3 and 7.0 in patients with a drain, respectively. Preoperative anemia and the insertion of drains are more predictive for RBC transfusions than the use of tranexamic acid. Based on this, a personalized transfusion probability can be computed, that may help to identify patients who could benefit from blood saving programs.

Abstract
BACKGROUND Total joint arthroplasties aim to improve quality of life from joint-related pain. Jehovah's Witnesses refuse blood products due to their religious beliefs. Surgeons may be reluctant to perform arthroplasty procedures on these patients for fear of uncontrolled bleeding. However, we hypothesize that through preoperative optimization, arthroplasty can be performed safely. METHODS We retrospectively reviewed 184 total joint arthroplasties in Jehovah's Witnesses between 2011 and 2019. Each patient was enrolled in the institutions' Bloodless Medicine program. Hemoglobin levels were recorded through standard laboratory testing while in the hospital. Primary outcomes were changes in preoperative and postoperative hemoglobin measures, short-term outcomes measures, and complications. RESULTS A total of 103 total knee arthroplasties (8 revisions) and 81 total hip arthroplasties (5 revisions) were performed. Hemoglobin drift was 2.5 ± 1.0 for primary TKA and 2.6 ± 1.3 for primary THA (p = 0.570). Hemoglobin drift was 1.9 ± 0.9 for revision TKA and 1.9 ± 0.2 for revision THA (p = 0.990). Only 2.7% of patients met the transfusion requirement of 7 g/dL. The major complication rate for the cohort was 1.6% systemic and 4.9% local, respectively, with no mortalities. The overall readmission rate was 2.7%. CONCLUSION To our knowledge, this is the largest reported sample of Jehovah's Witness patients undergoing total joint arthroplasty. Postoperative hemoglobin values did not prompt additional intervention in the overwhelming majority of patients, and complication rates were acceptable. Our data suggest that primary arthroplasty is safe in the Jehovah's Witness population. Additionally, we show preliminary evidence that revision arthroplasty is safe in Jehovah's Witness patients.

[PMID: 33260331 PMCID: PMC7760070 DOI: 10.3390/jcm9123880] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2020] [Revised: 11/23/2020] [Accepted: 11/25/2020] [Indexed: 12/13/2022] Open
Abstract
The topical application of tranexamic acid (TXA) helps to prevent post-operative blood loss in total joint replacements. Despite these findings, the effects on articular and periarticular tissues remain unclear. Therefore, this in vitro study examined the effects of varying exposure times and concentrations of TXA on proliferation rates, gene expression and differentiation capacity of chondrocytes and human mesenchymal stromal cells (hMSCs), which underwent osteogenic differentiation. Chondrocytes and hMSCs were isolated and multiplied in monolayer cell cultures. Osteogenic differentiation of hMSCs was induced for 21 days using a differentiation medium containing specific growth factors. Cell proliferation was analyzed using ATP assays. Effects of TXA on cell morphology were examined via light microscopy and histological staining, while expression levels of tissue-specific genes were measured using semiquantitative RT-PCR. After treatment with 50 mg/mL of TXA, a decrease in cell proliferation rates was observed. Furthermore, treatment with concentrations of 20 mg/mL of TXA for at least 48 h led to a visible detachment of chondrocytes. TXA treatment with 50 mg/mL for at least 24 h led to a decrease in the expression of specific marker genes in chondrocytes and osteogenically differentiated hMSCs. No significant effects were observed for concentrations beyond 20 mg/mL of TXA combined with exposure times of less than 24 h. This might therefore represent a safe limit for topical application in vivo. Further research regarding in vivo conditions and effects on hMSC functionality are necessary to fully determine the effects of TXA on articular and periarticular tissues.

Is Routine Hemoglobin Monitoring Necessary after Elective Hip and Knee Arthroplasty? Arthroplast Today 2020; 6:803-806. [PMID: 32984488 PMCID: PMC7498732 DOI: 10.1016/j.artd.2020.07.036] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2020] [Revised: 07/20/2020] [Accepted: 07/22/2020] [Indexed: 01/28/2023] Open
Abstract
Background Many orthopaedic units measure hemoglobin (Hb) levels after primary joint arthroplasty to identify patients with postoperative anemia. With the refinement of surgical techniques, blood loss in primary arthroplasty has decreased. The aim of this study was to investigate the postoperative Hb monitoring and transfusion practices in our own institution after elective hip or knee arthroplasty. Methods We conducted a retrospective audit of all patients who underwent elective total hip or knee arthroplasty in Galway University Hospital between March 1 and June 1, 2019. We recorded when they underwent postoperative Hb testing, whether or not they had a drop of Hb, which would indicate transfusion (<8 g/dL), and whether or not they were transfused. In patients who underwent transfusion, a chart review was performed to establish the presence of factors that would have triggered repeat Hb testing. Results One hundred thirty-six patients underwent elective primary hip or knee arthroplasty in the period. All had a full blood count sent on the first postoperative day. None (0%) had a clinically significant (to < 8g/dL) postoperative Hb drop on day 1. Eighteen (13.2%) patients underwent repeat testing on day 2 or subsequently. Eight (5.9%) exhibited a drop in Hb to less than 8 g/dL, with a mean Hb drop of 4.26 (standard error of the mean ± 0.862, standard deviation ± 0.98), and 5 (3.7%) proceeded to undergo allogenic blood product transfusion. All 5 underwent documented indications for repeat Hb testing. Conclusions There is no evidence for performing routine Hb testing on day 1 after elective hip or knee arthroplasty. We recommend that postoperative Hb testing should only be carried out on patients with additional indications.
