Racial Disparities in Treatment and Outcomes of Patients With Hepatitis C Undergoing Elective Total Joint Arthroplasty. J Arthroplasty 2024; 39:1671-1678. [PMID: 38331360 DOI: 10.1016/j.arth.2024.01.054] [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: 06/14/2023] [Revised: 01/25/2024] [Accepted: 01/29/2024] [Indexed: 02/10/2024] Open
Abstract
BACKGROUND African Americans have the highest prevalence of chronic Hepatitis C virus (HCV) infection. Racial disparities in outcome are observed after elective total hip arthroplasty (THA) and total knee arthroplasty (TKA). This study sought to identify if disparities in treatments and outcomes exist between Black and White patients who have HCV prior to elective THA and TKA. METHODS Patient demographics, comorbidities, HCV characteristics, perioperative variables, in-hospital outcomes, and postoperative complications at 1-year follow-up were collected and compared between the 2 races. Patients who have preoperative positive viral load (PVL) and undetectable viral load were identified. Chi-square and Fisher's exact tests were used to compare categorical variables, while 2-tailed Student's Kruskal-Wallis t-tests were used for continuous variables. A P value of less than .05 was statistically significant. RESULTS The liver function parameters, including aspartate aminotransferase and model for end-stage liver disease scores, were all higher preoperatively in Black patients undergoing THA (P = .01; P < .001) and TKA (P = .03; P = .003), respectively. Black patients were more likely to undergo THA (65.8% versus 35.6%; P = .002) and TKA (72.1% versus 37.3%; 0.009) without receiving prior treatment for HCV. Consequently, Black patients had higher rates of preoperative PVL compared to White patients in both THA (66% versus 38%, P = .006) and TKA (72% versus 37%, P < .001) groups. Black patients had a longer length of stay for both THA (3.7 versus 3.3; P = .008) and TKA (4.1 versus 3.0; P = .02). CONCLUSIONS The HCV treatment prior to THA and TKA with undetectable viral load has been shown to be a key factor in mitigating postoperative complications, including joint infection. We noted that Black patients were more likely to undergo joint arthroplasty who did not receive treatment and with a PVL. While PVL rates decreased over time for both races, a significant gap persists for Black patients.

Curtailing infection risks in hepatitis C patients: the effect of antiviral treatment in revision shoulder arthroplasty. J Shoulder Elbow Surg 2024; 33:1528-1535. [PMID: 38104720 DOI: 10.1016/j.jse.2023.10.030] [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: 06/26/2023] [Revised: 10/19/2023] [Accepted: 10/30/2023] [Indexed: 12/19/2023]
Abstract
BACKGROUND Revision shoulder arthroplasty (RevSA) is a complex procedure that can result in various postoperative complications. However, the impact of hepatitis C virus (HCV) on postoperative complications after RevSA remains unclear because of limited and inconsistent evidence. This study aims (1) to investigate the incidence of postoperative complications in patients with HCV undergoing RevSA and (2) to evaluate the impact of HCV treatment on complication rates at different time points after the revision procedure, specifically at 90 days, 1 year, and 2 years. METHODS We queried a national, all-payer database to investigate recent trends in the use of RevSA among HCV patients to assess postoperative complication rates, including venous thromboembolism (VTE), wound complication, transfusion, and periprosthetic joint infection (PJI). Statistical analyses involved propensity score matching to create balanced cohorts and logistic regression to determine the relative risk of postoperative complications. Data were analyzed with SPSS software (version 24.0 for Windows). The study included patients who underwent partial or total RevSA procedures between January 1, 2010, and December 31, 2020. Patients were identified based on medical claims that included procedural codes for RevSA and associated diagnosis codes for PJI or insertion/removal of an antibiotic spacer. A Bonferroni correction was used because many tests were performed and statistical significance was set at P = .0125. RESULTS The HCV cohort demonstrated higher PJI rates at 1-year (5.5% vs. 3.9%, P = .006) and 2-year follow-ups (6.7% vs. 4.6%, P = .006). However, no significant differences emerged in VTE and wound complication rates between the HCV and non-HCV cohorts. Comparing untreated and treated HCV patients, the former showed significantly higher PJI rates at 2 years (P = .010), whereas the treated group had significantly lower odds ratios for PJI. When comparing treated HCV patients with the non-HCV cohort, minimal differences were found in postoperative outcomes, indicating no significant difference in the risk of complications between the groups. CONCLUSION Our study observed an association between HCV patients who received antiviral treatment prior to RevSA and a reduced incidence of PJI compared to untreated HCV patients. When comparing this group to the non-HCV controls, there was no significant difference in the incidence of PJI, suggesting a potential association between antiviral treatment and the observed risk patterns in HCV patients. Proper management of HCV-positive patients during RevSA is crucial for improving outcomes and reducing complications.

Abstract
BACKGROUND Hepatitis C is associated with increased adverse events following surgery. The goals of this study were therefore to evaluate postoperative outcomes in patients with hepatitis C following ankle arthrodesis. MATERIALS AND METHODS A review of Medicare patients was performed to identify patients who underwent ankle arthrodesis. Patients were then divided into those with a preoperative history of hepatitis C and those who did not and were matched using propensity scores. Outcomes of interest were analyzed using multivariate logistic regression. RESULTS A diagnosis of hepatitis C was associated with a significantly increased risk of myocardial infarction, emergency department visits, and readmission within 90 days following surgery. In addition, hepatitis C is associated with an increased length of stay, cost of hospitalization, and total hospital charge. CONCLUSIONS A diagnosis of hepatitis C was associated with a significant increase in hospital resource utilization during the initial inpatient stay and the immediate post-discharge period.Level of Evidence: III.

Abstract
Knee osteoarthritis (OA) is one of the leading causes of disability around the globe. Osteoarthritis is mainly considered a disease affecting the elderly. However, more and more studies show that sports overuse, obesity, or congenital disorders can initiate a pathologic cascade that leads to OA changes in the younger population. Nevertheless, OA mostly affects the elderly, and with increasing life expectancy, the disease will develop in more and more individuals. To date, the golden standard in the treatment of the end-stage of the disease is total joint replacement (TJR), which restores painless knee motion and function. One of the weakest elements in TJR is its bonding with the bone, which can be achieved by bonding material, such as poly methyl-methacrylate (PMMA), or by cementless fixation supported by bone ingrowth onto the endoprosthesis surface. Each technique has its advantages; however, the most important factor is the revision rate and survivor time. In the past, numerous articles were published regarding TJR revision rate, but no consensus has been established yet. In this review, we focused on a comparison of cemented and cementless total knee replacement surgeries. We introduced PICO rules, including population, intervention, comparison and outcomes of TJR in a PubMed search. We identified 783 articles published between 2010 and 2023, out of which we included 14 in our review. Our review reveals that there is no universally prescribed approach to fixate knee prostheses. The determination of the most suitable method necessitates an individualized decision-making process involving the active participation and informed consent of each patient.

Abstract
INTRODUCTION Periprosthetic joint infection (PJI) is a serious complication after total joint arthroplasty. It is important to accurately identify PJI and monitor postoperative blood biochemical marker changes for the appropriate treatment strategy. In this study, we aimed to monitor the postoperative blood biochemical characteristics of PJI by contrasting with non-PJI joint replacement cases to understand how the characteristics change postoperatively. MATERIALS AND METHODS A total of 144 cases (52 of PJI and 92 of non-PJI) were reviewed retrospectively and split into development and validation cohorts. After exclusion of 11 cases, a total of 133 (PJI: 50, non-PJI: 83) cases were enrolled finally. An RF classifier was developed to discriminate between PJI and non-PJI cases based on 18 preoperative blood biochemical tests. We evaluated the similarity/dissimilarity between cases based on the RF model and embedded the cases in a two-dimensional space by Uniform Manifold Approximation and Projection (UMAP). The RF model developed based on preoperative data was also applied to the same 18 blood biochemical tests at 3, 6, and 12 months after surgery to analyze postoperative pathological changes in PJI and non-PJI. A Markov chain model was applied to calculate the transition probabilities between the two clusters after surgery. RESULTS PJI and non-PJI were discriminated with the RF classifier with the area under the receiver operating characteristic curve of 0.778. C-reactive protein, total protein, and blood urea nitrogen were identified as the important factors that discriminates between PJI and non-PJI patients. Two clusters corresponding to the high- and low-risk populations of PJI were identified in the UMAP embedding. The high-risk cluster, which included a high proportion of PJI patients, was characterized by higher CRP and lower hemoglobin. The frequency of postoperative recurrence to the high-risk cluster was higher in PJI than in non-PJI. CONCLUSIONS Although there was overlap between PJI and non-PJI, we were able to identify subgroups of PJI in the UMAP embedding. The machine-learning-based analytical approach is promising in consecutive monitoring of diseases such as PJI with a low incidence and long-term course.

Child-Pugh Class B or C Liver Disease Increases the Risk of Early Mortality in Patients With Hepatitis C Undergoing Elective Total Joint Arthroplasty Regardless of Treatment Status. Clin Orthop Relat Res 2023; 481:2016-2025. [PMID: 36961471 PMCID: PMC10499110 DOI: 10.1097/corr.0000000000002631] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Revised: 01/20/2023] [Accepted: 02/28/2023] [Indexed: 03/25/2023]
Abstract
BACKGROUND Patients with hepatitis C virus (HCV) undergoing primary elective total joint arthroplasty (TJA) are at increased risk of postoperative complications. Patients with chronic liver disease and cirrhosis, specifically Child-Pugh Class B and C, who are undergoing general surgery have high 2-year mortality risks, approaching 60% to 80%. However, the role of Child-Pugh and Model for End-Stage Liver Disease classifications of liver status in predicting survivorship among patients with HCV undergoing elective arthroplasty has not been elucidated. QUESTION/PURPOSE What factors are independently associated with early mortality (< 2 years) in patients with HCV undergoing arthroplasty? METHODS We performed a retrospective study at three tertiary academic medical centers and identified patients with HCV undergoing primary elective TJA between January 2005 and December 2019. Patients who underwent revision TJA and simultaneous primary TJA were excluded. A total of 226 patients were eligible for inclusion in the study. A further 25% (57) were excluded because they were lost to follow-up before the minimum study requirement of 2 years of follow-up or had incomplete datasets. After the inclusion and exclusion criteria were applied, the final cohort consisted of 75% (169 of 226) of the initial patient population eligible for analysis. The mean follow-up duration was 53 ± 29 months. We compared confounding variables for mortality between patients with early mortality (16 patients) and surviving patients (153 patients), including comorbidities, HCV and liver characteristics, HCV treatment, and postoperative medical and surgical complications. Patients with early postoperative mortality were more likely to have an associated advanced Child-Pugh classification and comorbidities including peripheral vascular disease, end-stage renal disease, heart failure, and chronic obstructive pulmonary disease. However, both groups had similar 90-day and 1-year medical complication risks including myocardial infarction, stroke, pulmonary embolism, and reoperations for periprosthetic joint infection and mechanical failure. A multivariable regression analysis was performed to identify independent factors associated with early mortality, incorporating all significant variables with p < 0.05 present in the univariate analysis. RESULTS After accounting for significant variables in the univariate analysis such as peripheral vascular disease, end-stage renal disease, heart failure, chronic obstructive pulmonary disease, and liver fibrosis staging, Child-Pugh Class B or C classification was found to be the sole factor independently associated with increased odds of early (within 2 years) mortality in patients with HCV undergoing elective TJA (adjusted odds ratio 29 [95% confidence interval 5 to 174]; p < 0.001). The risk of early mortality in patients with Child-Pugh Class B or C was 64% (seven of 11) compared with 6% (nine of 158) in patients with Child-Pugh Class A (p < 0.001). CONCLUSION Patients with HCV and a Child-Pugh Class B or C at the time of elective TJA had substantially increased odds of death, regardless of liver function, cirrhosis, age, Model for End-Stage Liver Disease level, HCV treatment, and viral load status. This is similar to the risk of early mortality observed in patients with chronic liver disease undergoing abdominal and cardiac surgery. Surgeons should avoid these major elective procedures in patients with Child-Pugh Class B or C whenever possible. For patients who feel their arthritic symptoms and pain are unbearable, surgeons need to be clear that the risk of death is considerably elevated. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
BACKGROUND Although the impact of microbial infections on orthopedic clinical outcomes is well recognized, the influence of viral infections on the musculoskeletal system might have been underestimated.
AIM To systematically review the available evidence on risk factors and musculoskeletal manifestations following viral infections and to propose a pertinent classification scheme.
METHODS We searched MEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL), the Reference Citation Analysis (RCA), and Scopus for completed studies published before January 30, 2021, to evaluate risk factors and bone and joint manifestations of viral infection in animal models and patient registries. Quality assessment was performed using SYRCLE's risk of bias tool for animal studies, Moga score for case series, Wylde score for registry studies, and Newcastle-Ottawa Scale for case-control studies.
RESULTS Six human and four animal studies were eligible for inclusion in the qualitative synthesis. Hepatitis C virus was implicated in several peri- and post-operative complications in patients without cirrhosis after major orthopedic surgery. Herpes virus may affect the integrity of lumbar discs, whereas Ross River and Chikungunya viruses provoke viral arthritis and bone loss.
CONCLUSION Evidence of moderate strength suggested that viruses can cause moderate to severe arthritis and osteitis. Risk factors such as pre-existing rheumatologic disease contributed to higher disease severity and duration of symptoms. Therefore, based on our literature search, the proposed clinical and pathogenetic classification scheme is as follows: (1) Viral infections of bone or joint; (2) Active bone and joint inflammatory diseases secondary to viral infections in other organs or tissues; and (3) Viral infection as a risk factor for post-surgical bacterial infection.

Abstract
Background Preoperative treatment recommendations and optimal time to perform total joint arthroplasty (TJA) in patients with hepatitis C virus after treatment completion for achieving best outcomes have not been elucidated. We aim to determine (1) if undetectable viral load (UVL) prior to TJA leads to decreased postoperative complication rates, specifically periprosthetic joint infection (PJI), and (2) if delaying TJA after treatment completion has benefit in decreasing PJI. Methods A retrospective review of all hepatitis C virus patients undergoing TJA at 3 academic tertiary care centers was conducted. A total of 270 TJAs performed from 2005 to 2019 were included, 125 with positive viral load at the time of surgery. The duration from completion of treatment regimen to TJA was recorded for the UVL cohort. The primary study outcome was PJI at 1-year follow-up. Secondary outcomes included in-hospital complications, mechanical revision TJA rates, and optimal time to TJA upon completion of treatment. Results Patients with positive viral load at the time of TJA had longer length of stay (3.9 vs 2.9 days, P < .0001) and a higher PJI rate at 1 year postoperatively (9% vs 2%, P = .02) than UVL patients. There was no difference of in-hospital complications or revision rates for mechanical etiologies. Delaying TJA after achieving a sustained virologic response did not impact PJI rates. Conclusions Sustained UVL prior to TJA is critical to minimize PJI irrespective of the treatment regimen utilized. Surgery can be performed with lower complication rates any time after achieving sustained virologic response. Level of Evidence Level III, prognostic retrospective cohort study.

Abstract
Background Hepatitis C virus (HCV) is associated with increased complications of risk after arthroplasty. The purpose of this study was to examine the impact of HCV and a pre-arthroplasty antiviral treatment on complications following total shoulder arthroplasty (TSA). Methods A retrospective matched cohort study was conducted using an administrative claims database. Patients who underwent TSA were identified with Current Procedural Terminology -23472 and International Classification of Diseases procedural codes. A total of 1244 HCV patients were matched 1:3 with 3732 noninfected controls across age, sex, diabetes mellitus, tobacco use, and obesity. The HCV patients with treatment before TSA were identified by claims containing antiviral drug codes. Multivariable logistic regression was used to compare rates of 90-day medical complications and prosthesis-related complications within 2 years postoperatively for (1) HCV patients vs. controls, (2) antiviral-treated HCV patients vs. controls, and (3) antiviral-treated HCV patients vs. untreated HCV patients. Results Patients with HCV exhibited significantly higher rates of blood transfusion (OR 2.12), acute kidney injuries (OR 1.86), inpatient readmission (OR 2.06), revision TSA (OR 1.48), dislocation (OR 1.92), mechanical complications (OR 1.39), and prosthetic joint infection (OR 1.53) compared to controls. Antiviral-treated HCV patients exhibited a significantly lower rate of myocardial infarction (OR 0.27) and comparable rates of all other complications relative to controls (all P > .05). Compared to untreated HCV patients, antiviral-treated HCV patients exhibited significantly lower rates of 90-day medical complications (OR 0.57) and prosthetic joint infection (OR 0.36). Conclusions HCV is associated with significantly increased complication rates after TSA. Antiviral treatment before TSA may reduce the risk of postoperative complications.

Abstract
BACKGROUND Despite the fact that patients with chronic liver disease (CLD) are at increased risk of complications after a fracture of the hip, there remains little information about the risk factors for acute postoperative complications and their overall outcome.The aim of this study was to describe inpatient postoperative complications and identify predictors of postoperative morbidity. METHODS Patients with CLD who had been treated for a fracture of the hip between April 2005 and August 2019 were identified from a retrospective search of an intramural trauma registry based in the Northeastern United States. Medical records were reviewed for baseline demographics, preoperative laboratory investigations, and outcomes. RESULTS The trauma registry contained 110 patients with CLD who had undergone surgery for a fracture of the hip. Of these, patients with a platelet-count of ⩽100,000/µL were 3.81 (95% CI, 1.59-9.12) times more likely to receive a transfusion than those with a platelet-count of >100,000/µL. Those with a Model for End-stage Liver Disease (MELD) score of >9 were 5.54 (2.33-13.16) times more likely to receive a transfusion and 3.97 (1.06-14.81) times more likely to develop postoperative delirium than those with a MELD score of ⩽9.Of patients without chronic kidney disease, those with a creatinine of ⩾1.2 mg/dL were 6.80 (1.79-25.87) times more likely to develop acute renal failure (ARF) than those with a creatinine of <1.2 mg/dL. In a multivariable model, as MELD score was increased, the odds of developing a composite postoperative complication, which included transfusion, ARF, delirium, or deep wound infection, were 1.29 (1.01-1.66). Other tools used to assess surgical risks, Charlson Comorbidity Index, Elixhauser, and American Society of Anesthesiologist scores, were not predictive. CONCLUSIONS Patients with CLD who undergo surgery for a hip fracture have a high rate of postoperative complications which can be predicted by the preoperative laboratory investigations identified in this study and MELD scores, but not by other common comorbidity indices.

Abstract
BACKGROUND Hepatitis C virus (HCV) is associated with increased complication risk after elective arthroplasty. The purpose of this study is to examine the impact of HCV and prearthroplasty antiviral treatment on complications following total hip arthroplasty (THA). METHODS A retrospective matched cohort study was conducted using an administrative claims database. In total, 6,883 HCV patients were matched 1:3 with 20,694 noninfected controls, and 920 HCV patients with antiviral treatment before THA (treated HCV) were matched 1:4 with 3,820 HCV patients without treatment (untreated HCV). Rates of 90-day medical complications and joint complications within 2 years postoperatively were compared with multivariable logistic regression. RESULTS HCV patients exhibited significantly increased rates of medical complications within 90 days compared to noninfected controls (all P < .01). At 2 years postoperatively, HCV patients also exhibited significantly higher risk of revision THA (odds ratio [OR] 1.81), dislocation (OR 2.06), mechanical complications (OR 1.40), periprosthetic fracture (OR 1.76), and prosthetic joint infection (PJI) (OR 1.79). However, treated HCV patients exhibited statistically comparable risk of all joint complications at 2 years postoperatively relative to controls (all P > .05). Compared to untreated HCV patients, treated HCV patients exhibited significantly lower risk of inpatient readmission within 90 days (OR 0.58) and PJI at 2 years postoperatively (OR 0.62). CONCLUSION HCV patients exhibit significantly increased risk of medical and joint complications following THA relative to controls, though prearthroplasty antiviral treatment mitigates complication risk. Treated HCV patients exhibited significantly lower risk of inpatient readmission and PJI compared to untreated HCV patients. LEVEL OF EVIDENCE Level III.

Abstract
Aims The purpose of this study was to compare the clinical outcomes, mortalities, implant survival rates, and complications of total knee arthroplasty (TKA) in patients with or without hepatitis B virus (HBV) infection over at least ten years of follow-up. Methods From January 2008 to December 2010, 266 TKAs were performed in 169 patients with HBV (HBV group). A total of 169 propensity score–matched patients without HBV were chosen for the control group in a one-to-one ratio. Then, the clinical outcomes, mortalities, implant survival rates, and complications of TKA in the two groups were compared. The mean follow-up periods were 11.7 years (10.5 to 13.4) in the HBV group and 11.8 years (11.5 to 12.4) in the control group. Results The mean Knee Society scores in the HBV and control groups improved from 37.1 (SD 5.6) and 38.4 (SD 5.4) points preoperatively to 78.1 (SD 10.8) and 81.7 (SD 10.2) points at final follow-up (p = 0.314), while the mean function scores in the HBV and control groups improved from 36.2 and 37.3 points preoperatively to 77.8 and 83.2 points at final follow-up (p = 0.137). Nine knees in the HBV group required revision surgery, including seven due to septic loosening and two due to aseptic loosening. Four knees in the control group required revision surgery, including three due to septic loosening and one due to aseptic loosening. Kaplan–Meier survivorship analysis with the revision of either component as an endpoint in the HBV and control groups estimated 96.6% and 98.5% chances of survival for ten years, respectively (p = 0.160). Conclusion TKA in patients with HBV infection resulted in good clinical outcomes and survivorship. However, there was a higher revision rate over a minimum ten-year follow-up period compared to TKA in patients without HBV infection. Cite this article: Bone Jt Open 2022;3(6):470–474.

Abstract
BACKGROUND Hepatitis C (HCV) is undertreated and increasing in prevalence. Its influence on outcomes following total knee arthroplasty (TKA) remains unclear. The purpose of this study is to examine the impact of HCV and prearthroplasty antiviral treatment on postoperative complications following TKA. METHODS A retrospective matched cohort study was conducted using an administrative claims database to compare postoperative complication rates following TKA for (1) patients with vs without HCV and (2) among patients with HCV, patients with antiviral treatment before TKA vs no treatment. In total, 6971 patients with HCV were matched 1:4 with 27,884 controls without HCV, and 708 HCV patients with antiviral treatment before TKA were matched 1:2 with 1416 HCV patients without treatment. Rates of joint complications at 1 and 2 years postoperatively were compared via multivariable logistic regression. RESULTS The HCV cohort exhibited significantly higher risk of prosthetic joint infection (PJI) than controls at both 1 (4.1 vs 2.1%; odds ratio [OR] 1.58) and 2 years (5.0% vs 2.7%; OR 1.55) postoperatively. Rates of revision TKA were also significantly higher for HCV patients at 1 (2.8% vs 1.8%; OR 1.40) and 2 years (4.1% vs 2.9%; OR 1.30). HCV patients with prearthroplasty antiviral treatment exhibited significantly lower risk of PJI at 1 (2.1% vs 4.1%; OR 0.50) and 2 years (2.7% vs 5.1%, OR 0.51) compared to patients without treatment. CONCLUSION Patients with HCV have significantly increased risk of PJI and revision arthroplasty following TKA. Antiviral treatment before TKA significantly decreases the risk of PJI postoperatively.

Abstract
BACKGROUND Whether hepatitis C virus (HCV)-positive patients are at risk for increased complications and long hospital stay following total joint arthroplasty (TJA) remains unclear. Therefore we performed a meta-analysis aiming to answer the following question: (1) are there differences in postoperative complications including joint infection and mortality between patients with or without hepatitis C following TJAs? (2) Are patients without HCV be associated with less blood loss, shorter hospital stay, lower readmission rate, higher function scores, lower revision and reoperation rates than patients with HCV? METHODS A meta-analysis was conducted to pool data and quantitatively assessing the association between HCV infection and risks for adverse postoperative outcomes. A systematic search of all published studies concerning HCV and TJA was performed in five bibliographic databases, including PubMed, EMBASE, China National Knowledge Infrastructure, Web of Science, and the Cochrane Library databases. Random-effects meta-analysis of odds ratios (OR) was accomplished according to the classification of adverse events, subgroup analyses were performed based on surgery type. RESULTS Fifteen eligible observational studies were included with a sample size of 9,788,166 patients. Overall pooled data revealed the increased risk of overall complications, including medical and surgical complications, in HCV-positive patients undergoing TJA compared with than in HCV-negative people (OR 1.57; 95%CI: 1.44-1.71 [p<0.00001]). Joint infections were highly common in HCV-positive patients undergoing lower-extremity TJA (OR 2.06; 95%CI: 1.73-2.47 [p<0.00001]). Furthermore, HCV infections were associated with high rates of reoperations and revisions (OR 1.47; 95%CI: 1.40-1.55 [p<0.00001]). CONCLUSIONS Patients with hepatitis C have an increased risk of adverse outcomes post-TJA and a high risk of reoperation and revision that is partially attributed to postoperative complications, particularly joint infections.

Abstract
Objective To evaluate the operative methods and clinical results of surgical treatment in a case series of 10 patients with hemophilic pseudotumors. Methods Ten patients with hemophilic pseudotumors who received surgical resection treatment in our hospital from October 2017 to June 2020 were retrospectively reviewed. All patients were hemophilia A (factor VIII deficiency).The age range was 20–51 years. Preoperative imaging examination revealed the size of irregular mass from 8.2 cm× 3.3 cm× 2.3 cm to 22.3 cm× 15.5 cm× 17.0 cm. With the supplementary of recombinant coagulation factor VIII, five cases received complete resection; one received resection and skin grafting; one received cytoreduction surgery as the pseudotumor closing to iliac vessel and nerve; three cases received complete resection and construction as bone destruction. The perioperative variables were recorded and all the patients were followed in the outpatient clinic. Clinical and radiological assessments were conducted. Results In these patients, the average intraoperative blood loss volume was 783.1 mL (range, 240–2100 mL). Six patients received blood transfusion during perioperative period. The average duration of surgery was 140.7 min (range, 110–240 min). All wounds healed smoothly and there was no infection or chronic sinus formation. The average length of hospital stay was 16.3 days (range, 12–25 days). There is no iatrogenic vascular nerve injury in our series. Complete follow‐up was performed in all patients. Mean follow‐up duration was 14.2 months (range, 6–26 months). One patient with pseudotumor in the thigh had a recurrence 1 year after operation, then secondary operation was performed. In three cases who received complete resection and construction, patient 8 obtained bone graft and late fixation. X‐ray examination showed bone formation in the lesion at the 2‐year follow‐ups after operation. Patient 9 underwent knee replacement, his left knee showed flexion deformity in preoparation. At the last follow‐up, range of motion was improved from 0° to 40° compared with preoperative status. Patient 10 had pseudotumor in the distal femur, received long bone graft and intramedullary nail fixation. Conclusions Surgical resection for hemophilic pseudotumors is an effective and safe method. The choice of surgical procedure must be individualized according to the localization and progress of pseudotumor.

Abstract
Total hip arthroplasty (THA) and total knee arthroplasty (TKA) are successful orthopaedic procedures with an ever-increasing demand annually worldwide, and persistent wound drainage (PWD) is a well-known complication following these procedures. Despite many definitions for PWD having been proposed, a validated description remains elusive. PWD is a risk factor for periprosthetic joint infection (PJI). PJI is a devastating complication of THA and TKA, and a leading cause of revision surgery with dramatic morbidity and mortality and a significant burden on health socioeconomics. Prevention of PJI has become an essential focus in THA and TKA. Understanding the pathophysiology, risk factors and subsequent management of PWD may aid in decreasing the rate of PJI. Risk factors of PWD can be divided into modifiable and non-modifiable patient risk factors, pharmacological and surgical risk factors. No gold standard treatment protocol to address PWD exists; however, non-operative options progressing to surgical interventions have been described. The aim of this study was to review the current literature regarding PWD and consolidate the risk factors and management strategies available.

Abstract
BACKGROUND Patients with hepatitis C virus (HCV) have an increased risk of complications after total joint arthroplasty (TJA). There is a limited but growing body of evidence on the benefit of preoperative antiviral treatment to reduce complications after TJA. What has not been well established is the effect of preoperative antiviral treatment among those with advanced disease as indicated by hepatic fibrosis. METHODS In total, 270 patients at 2 urban medical centers were reviewed for patient demographics, comorbidities, HCV treatment, hepatic fibrosis status, surgical information, and postoperative complications. Patients were divided into 2 groups based on their antiviral treatment status prior to TJA: Treated (n = 129) and Untreated (n = 141). Pearson's chi-squared test, Student's t-test, and multivariate logistic regressions were used to analyze complications between groups. RESULTS Patients in the Treated group had significantly fewer all-type complications (4.7% vs 14.9%, P = .007), infections (2.3% vs 12.1%, P = .002), and reoperations (0.8% vs 9.9%, P = .001) compared to the Untreated group. After controlling for hepatic fibrosis, we found that Treated patients still had significantly lower odds of experiencing all-type complications (odds ratio [OR] 0.30, 95% confidence interval [CI] 0.10-0.88; P = .028), infection (OR 0.19, 95% CI 0.04-0.87; P = .033), and reoperation (OR 0.11, 95% CI 0.01-0.90; P = .039) following TJA. CONCLUSION HCV antiviral treatment reduces postoperative complications after primary TJA, even among those who have progressed to hepatic fibrosis. Surgeons can use this information in shared decision making prior to TJA to counsel patients about the benefits of preoperative antiviral treatment even in the presence of hepatic fibrosis.

Abstract
Background Few studies have evaluated the effect of hepatitis C (HCV) on primary total shoulder arthroplasty (TSA). Our purpose was to determine if HCV infection is associated with increased complication rates after TSA in United States (US) veterans and, secondarily, to determine if preoperative HCV treatment with direct-acting antivirals (DAAs) affects postoperative complication rates. Methods US Department of Veterans Affairs (VA) data sets were used to retrospectively identify patients without HCV, patients with untreated HCV, and patients with HCV treated with DAAs who underwent TSA from 2014 to 2019. Medical and surgical complications were assessed using International Classification of Diseases codes. Complication rates between patients with HCV (treated and untreated) and patients without HCV and between HCV-treated patients and HCV-untreated patients were compared at 90 days and 1 year after surgery. Results We identified 5774 primary TSAs that were performed at VA hospitals between 2014 and 2019. A minority (9.5%) of TSA patients had HCV, 23.4% of whom were treated preoperatively with DAAs. On multivariate analysis, HCV patients had increased odds of 1-year medical complications (odds ratio, 1.39; 95% confidence interval, 1.06-1.81, P = .016), when compared with patients without HCV. No statistically significant difference in complication rates was observed between HCV-treated and HCV-untreated patients. Discussion US veterans with a history of HCV are at an increased risk of developing medical but not surgical complications within the first year after TSA. Larger studies are necessary to evaluate the effects of DAA treatment on complication rates.

Prevalence of Hepatitis C Virus Infection in the Veteran Population Undergoing Total Joint Arthroplasty: An Update. J Arthroplasty 2021; 36:467-470. [PMID: 32900563 DOI: 10.1016/j.arth.2020.08.023] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2020] [Revised: 07/28/2020] [Accepted: 08/11/2020] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND In 2012, we reported on the prevalence of hepatitis C virus (HCV) infection in Veterans Affairs (VA) patients undergoing total joint arthroplasty (TJA) at our center. In this patient population, 8.4% were antibody positive and 4.5% were viremic with HCV. In 2014, the first all-oral direct-acting antiviral treatment for hepatitis C became available. The Department of Veterans Affairs then underwent an aggressive program to eradicate hepatitis C from the veteran population. The purpose of this report is to provide updated information on the prevalence of HCV viremia among patients undergoing primary TJA at the same center. METHODS A retrospective review was performed of all patients undergoing primary TJA at a single VA medical center in 2019. Anti-HCV antibody and HCV viremia prevalence were calculated. Comparisons were made to data from a previously reported cohort of patients who had undergone TJA at the same center from 2007 to 2009. RESULTS Thirty-three (11.6%) of 285 patients screened preoperatively were positive for the hepatitis C antibody. Only one of the 33 anti-HCV-positive patients was viremic at the time of screening for an overall viremic prevalence of 0.4%. We found no statistically significant difference in the birth year, or anti-HCV antibody-positive rate from the prior cohort, but the prevalence of HCV viremia decreased significantly. CONCLUSION Because direct-acting antiviral HCV treatment has become available, HCV viremia among VA patients undergoing TJA has been reduced from 4.5% to 0.4%. Surgeons are still advised to minimize the risk of sharps injury.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE The aim of this study was to identify whether hepatitis C virus (HCV) diagnosis influences in-hospital lengths of stay (LOS), postoperative complications, readmission rates, or costs following primary posterior lumbar fusions in an elective setting. SUMMARY OF BACKGROUND DATA Although joint arthroplasty literature has shown increased complication rates and costs for patients seropositive with HCV without liver disease compared to those without HCV, this comorbidity has not been explored in the spine literature. To our knowledge, this is the first publication in the lumbar spine literature to solely focus on HCV as the disease burden. METHODS A national database was queried for patients who underwent primary lumbar spine fusion for degenerative lumbar pathology with Medicare insurance from 2005 to 2014. The 90-day postoperative complication rates, readmission rates, and treatment costs were queried. To limit confounding, HCV patients were matched with a control cohort of non-HCV patients using patient demographics, treatment modality, and comorbid conditions, and then analyzed by multivariate logistic regression. Patients with active liver disease were excluded to better isolate HCV as the comorbidity. RESULTS A cohort of 28,841 patients were included in the final analysis. Postoperatively, compared to those without HCV infection, those with HCV had significantly higher odds of blood transfusions (odds ratio [OR]: 3.06), pneumonia (OR: 2.49), respiratory failure (OR: 2.49), urinary tract infections (OR: 1.89), wound-/implant-related infections (OR: 1.74), cerebrovascular events (OR: 1.70), or any postoperative complication within 90 days (OR: 2.93; all P < 0.0001). Furthermore, HCV positive patients had higher day of surgery costs ($28,713.26 vs. $25,448.26, P < 0.0001) and 90-day costs ($33,447.39 vs. $29,016.77, P < 0.0001). There was not a significant difference for patients with HCV infection compared to those without in regard to hospital LOS (10 days vs. 8 days, P = 0.332) and rates of a 90-day readmission (0.37% vs. 0.22%; OR: 1.70, 95% confidence interval: 1.00-2.90, P: 0.050). CONCLUSION In patients undergoing primary lumbar fusion, a seropositivity for HCV without liver disease is associated with higher costs and complication rates, including higher rates of blood transfusion requirements and pneumonia-related complications. This data shed new light on elective spine surgery in HCV patients and may influence the risks and benefits considerations for surgeons considering lumbar fusion in this population.

[PMID: 32147342 DOI: 10.1016/j.arth.2020.02.018] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2019] [Revised: 01/31/2020] [Accepted: 02/08/2020] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND There are little data on the outcomes of primary total hip arthroplasties (THAs) in patients with a prior surgically treated hip or knee periprosthetic joint injection (PJI). The goal of this study was to compare the risk of infection in this population with matched controls. METHODS We retrospectively reviewed 48 patients whom underwent 50 primary THAs from 2000 to 2014 with a history of a PJI in a total knee arthroplasty or contralateral THA. Thirteen patients (27%) were on chronic antibiotic suppression at the time of primary THA. Mean age was 67 years, and mean body mass index was 35 kg/m2. Mean follow-up was 6 years. We 1:3 matched (age, sex, body mass index, cemented vs cementless femoral fixation, and surgical year) these cases to 150 primary THAs. Competing risk analysis, with death as the competing risk, was performed. RESULTS The cumulative incidence of PJI with death as a competing risk was 1.5-fold higher in the study cohort (2.0%) compared with matched controls (1.4%) (hazards ratio, 1.5; P = .75). The cumulative incidence of any infection with death as a competing risk was 2-fold higher in the study cohort (4.0%) compared with matched controls (2.1%) (hazards ratio, 2.0; P = .45). However, these were both statistically similar given the relatively small cohort. The overall complication rate, including infections and reoperations, was 17% in the study cohort. CONCLUSION Patients undergoing a clean primary THA with a history of a total knee arthroplasty or contralateral THA PJI in another joint have a 2% and 4% risk of PJI and any infection, respectively. Moreover, nearly 1 in 5 patients experience at least 1 complication.

Abstract
PURPOSE Knee arthropathy is a frequent complication affecting hemophilic patients, which can cause severe pain and disability. When conservative measures fail, total knee arthroplasty (TKA) may be performed. METHODS Eighteen TKA were performed in 15 patients with hemophilia during a 24-year period in a Hemophilia Comprehensive Care Center. All patients were evaluated by a multidisciplinary team constituted by a hematologist, an orthopedic surgeon, and a physical medicine and rehabilitation physician. Mean follow-up was 11.3 years. RESULTS Ten-year survival rate with prosthesis removal as end point was 94.3%. At last, follow-up visual analog pain scale score was 3.2 points, knee osteoarthritis outcome scale was 86.7 points, and mean range of motion was 88°. Only two patients required perioperative transfusion. Complication rate was 27.8% and included two infections, two prosthesis stiffness, and one case of recurrent hemarthrosis. CONCLUSION After appropriate medical optimization and with prompt rehabilitation, TKA can be performed in hemophilic patients with good clinical results and survivor rates comparable to nonhemophilic patients.

Abstract
BACKGROUND Previous reports establish that infection with hepatitis C virus (HCV) predisposes total joint arthroplasty (TJA) recipients to poor postoperative outcomes. The purpose of the present study is to assess whether variation in HCV VL influences perioperative outcomes following TJA. METHODS A multicenter retrospective review of all patients diagnosed with HCV who underwent primary TJA between January 2005 and April 2018 was conducted. Patients were stratified into 2 cohorts: (1) patients with an undetectable VL (U-VL) and (2) patients with a detectable VL (D-VL). Kaplan-Meier survivorship analysis was calculated with revision TJA as the end point. Subanalysis on the VL profile was done. RESULTS A total of 289 TJAs were included (U-VL:118 TJAs; D-VL:171 TJAs). Patients in the D-VL cohort had longer operative times (133.9 vs 109.2 minutes), higher intraoperative blood loss (298.4 vs 219.5 mL), longer inpatient hospital stays (4.0 vs 2.9 days), more postoperative infections (11.7% vs 4.2%), and an increased risk for revision TJA (12.9% vs 5.1%). Kaplan-Meier demonstrated that the U-VL cohort trended toward better survivorship (P = .17). On subanalysis of low and high VL, no difference in outcomes was appreciated. CONCLUSION TJA recipients with a detectable HCV VL have longer operative times, experience more intraoperative blood loss, have longer hospital length of stay, and are more likely to experience infection and require revision TJA. The blood loss, hospital length of stay, and revision rate findings should be interpreted with caution, however, as there are confounding factors. Our findings suggest that HCV VL is a modifiable risk factor that, can reduce the risk of infection and revision surgery. Additionally, serum HCV VL was not correlated with outcomes.

Abstract
INTRODUCTION Chronic liver disease (CLD) is a significant and increasingly prevalent co-morbidity in patients undergoing total hip arthroplasty (THA). These patients may develop metabolic bone disease (MBD) and systemic dysfunction, which pose challenges to THA surgery. This systematic review of literature aims to examine clinical outcomes and complications in patients with CLD undergoing THA and provide evidence-based approaches as to the optimization of their perioperative care. METHODS A Pubmed search was performed, identifying eight studies on 28 514 THAs for inclusion. Two additional studies reported on 44 patients undergoing THA post liver transplant. These were reviewed separately. RESULTS Increased early perioperative complications are reported recurrently. Review of long-term complications demonstrates an increased postoperative infection rate of 0.5% (p < 0.001) and perioperative mortality of 4.1% (p < 0.001). The need for revision surgery is more frequent at 4% (p < 0.001). Aetiology of need for revision surgery included; periprosthestic infection (70%), aseptic loosening (13%), instability (13%), periprosthetic fracture (2%) and liner wear (2%). THA in patients with liver transplants seems to offer functional improvement; however, no studies have formally assessed functional outcomes in the patient with active CLD. DISCUSSION A multidisciplinary perioperative approach is suggested in order to minimize increased complication risks. Specific measures include optimizing haemoglobin and taking measures to reduce infection. This review also highlights gaps in available literature and guides future research to appraise functional outcomes, further detail long-term failure reasons and study any differences in outcomes and complications based on the range of operative approaches and available implant choices.

Abstract
BACKGROUND It is estimated that 3%-8% of orthopedic patients, many of whom may undergo lower extremity total joint arthroplasty (TJA), are infected with hepatitis C virus. However, the impact of this virus on total joint arthroplasty is still undefined. METHODS Eligible studies were searched from electronic databases including PubMed, Web of Science, CNKI and OVID. Two researchers performed data extraction from eligible independently. Quality parameters and risk of bias in the included studies were assessed according to Cochrane's guidelines. The pooled Standardized Mean Difference (SMD) with a 95%CI was used to assess the outcomes of total joint arthroplasty in patients with the hepatitis C virus. RESULTS A total of 28 articles related to hepatitis C virus and total joint arthroplasty were reviewed. All clinical studies were eliminated and six articles containing ten studies eventually satisfied the eligibility criteria for this study. The pooled analysis showed hepatitis C had a higher complications rate than non-hepatitis C, with the pooled HR values of 1.55 (95%CI = 1.11-2.17, p = 0.01). As for THA, an overall pooled HR value (HR = 2.21, 95%CI = 1.19-4.10, p = 0.012) was obtained, indicating that patients with hepatitis C virus had a higher revision rate than non-hepatitis C. The infection rate was different between hepatitis C patients and non-hepatitis C controls (HR = 1.29, 95% = 1.17-1.44, P = 0.00). The combined analysis revealed a significantly longer length of hospital stay in patients with hepatitis C virus (HR = 0.88, 95%CI = 0.54-1.21, p = 0.000). CONCLUSIONS This is the first systematic review and meta-analysis investigating the impact of hepatitis virus on total joint arthroplasty. Based on this meta-analysis, we can draw a conclusion that the patients with hepatitis C virus have higher rates of complication, infection, and revision compared to patients with non-hepatitis virus. Besides, hepatitis C infected patients require a significant longer hospital stay than patients without hepatitis.

Abstract
AIMS There is little information regarding the risk of a patient developing prosthetic joint infection (PJI) after primary total knee arthroplasty (TKA) when the patient has previously experienced PJI of a TKA or total hip arthroplasty (THA) in another joint. The goal of this study was to compare the risk of PJI of primary TKA in this patient population against matched controls. PATIENTS AND METHODS We retrospectively reviewed 95 patients (102 primary TKAs) treated between 2000 and 2014 with a history of PJI in another TKA or THA. A total of 50 patients (53%) were female. Mean age was 69 years (45 to 88) with a mean body mass index (BMI) of 36 kg/m2 (22 to 59). In total, 27% of patients were on chronic antibiotic suppression. Mean follow-up was six years (2 to 16). We 1:3 matched these (for age, sex, BMI, and surgical year) to 306 primary TKAs performed in 306 patients with a THA or TKA of another joint without a subsequent PJI. Competing risk with death was used for statistical analysis. Multivariate analysis was followed to evaluate risk factors for PJI in the study cohort. RESULTS The cumulative incidence of PJI in the study cohort (6.1%) was significantly higher than the matched cohort (2.6%) at ten years (hazard ratio (HR) 3.3; 95% confidence interval 1.18 to 8.97; p = 0.02). Host grade in the study group was not a significant risk factor for PJI. Patients on chronic suppression had a higher rate of PJI (HR 15; p = 0.002), with six of the seven patients developing PJI in the study group being on chronic suppression. The new infecting microorganism was the same as the previous in only two of seven patients. CONCLUSION In this matched cohort study, patients undergoing a clean primary TKA with a history of TKA or THA PJI in another joint had a three-fold higher risk of PJI compared with matched controls with ten-year cumulative incidence of 6.1%. The risk of PJI was 15-fold higher in patients on chronic antibiotic suppression; further investigation into reasons for this and mitigation strategies are recommended.

Abstract
BACKGROUND Hepatitis C virus (HCV) is associated with poorer outcomes in total joint arthroplasty (TJA). Recently, oral direct-acting antivirals (DAAs) have become available for HCV curative treatment. The goal of this study is to determine if HCV may be a modifiable risk factor in TJA by comparing postoperative complications among patients with and without preoperative treatment for HCV. METHODS US Department of Veterans Affairs dataset of all consecutive primary TJAs performed between 2014 and 2018, when DAAs were available, was retrospectively reviewed. HCV-infected patients were identified using International Classification of Diseases, Ninth and Tenth Revision codes and laboratory values. HCV-infected patients treated prior to TJA with DAA were included in the "treated" group. HCV-infected patients untreated preoperatively were assigned to the "untreated" group. Medical and surgical complications up to 1 year postoperatively were identified using International Classification of Diseases, Ninth and Tenth Revision inpatient and outpatient codes. RESULTS In total, 42,268 patients underwent TJA at Veterans Affairs Hospitals between 2014 and 2018. About 6.0% (n = 2557) of TJA patients had HCV, 17.3% of whom received HCV treatment preoperatively. When evaluating inpatient and outpatient codes, implant infection rates were statistically lower at 90 days and 1 year postoperatively among HCV-treated patients than among those untreated. Odds ratios (ORs) favor lower infection rates in HCV-treated patients (90-day OR: 3.30, P = .045; 1-year OR: 2.16, P = .07). CONCLUSION Preoperative HCV treatment was associated with lower periprosthetic infection rates among US veterans undergoing TJA. Further investigation is necessary for definitive conclusions.

Abstract
BACKGROUND As the prevalence of chronic liver disease continues to rise in the United States, understanding the effects of liver dysfunction on surgical outcomes has become increasingly important. The objective of this study was to assess the effects of chronic liver disease on 30-day complications following adult spinal deformity (ASD) surgery. METHODS We performed a retrospective cohort study of 2337 patients in the 2008-2015 American College of Surgeons National Surgical Quality Improvement Program database who underwent corrective ASD surgery. Patients with liver disease were identified based on a Model for End-Stage Liver Disease-Na score ≥10. A univariate analysis was performed to compare 30-day postoperative complications between patients with and without liver disease. A multivariate regression analysis adjusting for differences in baseline patient characteristics was performed to identify complications that were associated with liver disease. RESULTS Patients with liver disease had a significantly greater incidence of postoperative pulmonary complications (6.3% vs. 2.9%; P < 0.001), blood transfusion (34.6% vs. 24.0%; P < 0.001), sepsis (2.2% vs. 0.9%; P = 0.011), prolonged hospitalization (19.0% vs. 8.0%; P < 0.001), as well as any 30-day complication (45.4% vs. 29.4%; P < 0.001). The multivariate regression analysis identified liver disease as a risk factor for prolonged hospitalization (odds ratio [OR] 2.16; 95% confidence interval [CI] 1.64-2.84; P < 0.001), pulmonary complications (OR 1.78; 95% CI 1.16-2.74; P = 0.009), blood transfusion (OR 1.67; 95% CI 1.36-2.05; P < 0.001), and any 30-day complication (OR 1.43; 95% CI 1.15-1.77; P = 0.001). CONCLUSIONS The multisystem pathophysiology of liver dysfunction predisposes patients to postoperative complications following ASD surgery. A multidisciplinary approach in surgical planning and preoperative optimization is needed to minimize liver disease-related complications and improve patient outcomes.

Abstract
AIMS With an ageing population of patients who are infected with hepatitis C virus (HCV), the demand for total knee arthroplasty (TKA) in this high-risk group continues to grow. It has previously been shown that HCV infection predisposes to poor outcomes following TKA. However, there is little information about the outcome of TKA in patients with HCV who have been treated successfully. The purpose of this study was to compare the outcomes of TKA in untreated HCV patients and those with HCV who have been successfully treated and have a serologically confirmed remission. PATIENTS AND METHODS A retrospective review of all patients diagnosed with HCV who underwent primary TKA between November 2011 and April 2018 was conducted. HCV patients were divided into two groups: 1) those whose HCV was cured (HCV-C); and 2) those in whom it was untreated (HCV-UT). All variables including demographics, HCV infection characteristics, surgical details, and postoperative medical and surgical outcomes were evaluated. There were 64 patients (70 TKAs) in the HCV-C group and 63 patients (71 TKAs) in the HCV-UT cohort. The mean age at the time of surgery was 63.0 years (sd 7.5; 44 to 79) in the HCV-C group and 61.7 years (sd 6.9; 47 to 88) in the HCV-UT group. RESULTS HCV-UT patients had a significantly longer mean hospital stay (3.4 days vs 2.9 days; p = 0.04), were more likely to be transferred to the intensive care unit (14.1% vs 4.3%; p = 0.04), and were significantly more often discharged to a post-acute care facility (39.4% vs 14.3%; p < 0.01). HCV-UT patients had significantly more postoperative infections (15.5% vs 4.3%; p = 0.03), surgical complications (21.1% vs 7.1%; p = 0.02), and revision TKA (12.7% vs 1.4%; p < 0.01) than HCV-C patients. CONCLUSION The preoperative treatment of HCV can reduce the risk of complications, including prosthetic joint infection and revision TKA. We recommend that HCV treatment regimens should be integrated into the preoperative optimization protocol for this high-risk group of patients. Cite this article: Bone Joint J 2019;101-B:667-674.

Abstract
BACKGROUND Patients with chronic hepatitis C (HCV) have had extremely high complication rates after total hip arthroplasty (THA). We sought to compare perioperative complication rates between untreated and treated HCV in THA patients and to compare these rates between patients treated with 2 different therapies (interferon vs direct antiviral agents). METHODS A multicenter retrospective database query was used to identify patients diagnosed with HCV who underwent THA between 2006 and 2016. All patients (n = 105) identified were included and divided into 2 groups: untreated (n = 63) and treated (n = 42) HCV; treated patients were further subdivided into those receiving interferon (n = 16) or direct antiviral agent therapies (n = 26). Comparisons between the treated and untreated groups were made with respect to demographic data, comorbidities, preoperative viral load, Model for End-Stage Liver Disease score, and all surgical and medical complications; a subgroup analysis of the treated patients was also performed. Separate independent t-tests or Mann-Whitney U tests were conducted for continuous variables. Categorical variables were compared using the chi-squared test of independence. RESULTS A greater number of untreated patients were human immunodeficiency virus infected (P = .01), while a reduced number of treated patients were either former or current smokers (P = .004). The untreated group had greater surgical complication rates (25.4% vs 4.8%; P = .007), with a higher rate of periprosthetic joint infection (14.3% vs 0%, P = .01). For treated patients, no differences were observed between treatment types for postsurgical complications. CONCLUSION Treatment for HCV prior to THA appears to be associated to fewer postoperative complications, primarily periprosthetic joint infection. Although further investigation is warranted, strong consideration should be given to treating patients for HCV prior to elective THA.

Abstract
OBJECTIVE To evaluate the relationship between noncirrhotic hepatitis C virus (HCV) infection, perioperative complications, and discharge status in patients undergoing surgical procedures for hip fractures. METHODS A retrospective epidemiological study was performed, querying the National Hospital Discharge Survey. Patients were selected using the International Classification of Diseases-9 diagnostic codes for hip fracture and primary procedural codes for open reduction internal fixation, hemiarthroplasty, total hip arthroplasty, or internal fixation. Patients with concurrent cirrhosis, HIV, hepatitis A, B, D, or E were excluded. Pearson χ tests, independent-samples t test, and multivariable binary logistic regression were used for data analysis. RESULTS Two cohorts surgically treated for a hip fracture were identified and compared. The first cohort included 5377 patients with a concurrent diagnosis of noncirrhotic HCV infection (HCV+) and the second included 4,712,159 patients without a diagnosis of HCV (HCV-). The HCV+ cohort was younger and had fewer medical comorbidities, yet was found to have a longer length of hospital stay, higher rates of nonroutine discharge, and higher rates of complications than the HCV- cohort. Multivariate regression analysis demonstrated that HCV+ is an independent risk factor for perioperative complications and nonroutine discharge. CONCLUSIONS In conclusion, our study demonstrates a negative association between noncirrhotic HCV infection and hip fracture surgery outcomes. Caution and appropriate preparation should be taken when surgically treating hip fractures in HCV+ patients because of higher risk of perioperative complications and nonroutine discharge.

Abstract
Background Little information exists regarding the risk of complications in inmates who receive total hip or knee arthroplasties in Canada. Inmates tend to be less healthy owing to socioeconomic factors and an increased number of medical and psychiatric comorbidities. We compared revision and complication rates of total joint replacements in a cohort of incarcerated Canadians versus a cohort of non-inmates. Methods We obtained a list of all Canadian inmate inpatient hospital visits with diagnostic/procedure codes of primary hip or knee arthroplasty within the last 10 years from our institution’s discharge abstract database. Demographic data and information related to the perioperative course, along with any data related to postoperative complications/readmissions, were obtained through manual chart review. Results The inmate group consisted of 20 men (mean age 58 yr) with a total of 24 primary total joint arthroplasties; the comparison group included 171 men (mean age 62 yr). Postoperatively, the inmates had a 4-fold increased risk of major complication compared with non-inmates (33.3% v. 7.6%; odds ratio 4.21, p = 0.01). The inmates’ revision rate was 20.8% compared with 5.8% in the comparison group (p = 0.03). The most common cause for revision in the inmate group was infection, with a rate of 16.7% compared with 3.5% in the comparison group (p = 0.03). Conclusion Patients requiring total joint arthroplasty who are inmates in the Canadian penitentiary system are at increased risk of complication and revision surgeries following total joint arthroplasty.

Abstract
BACKGROUND Arthroplasty outcomes and patient risk factors have not been studied in detail in safety net hospital settings. This study examines the relationship between selected risk factors and short-term complications in such a population, including a large subgroup with treated substance abuse. METHODS This retrospective cohort study contains 486 consecutive patients after primary hip and knee arthroplasty. One hundred three of these had a history of substance abuse and completed a 1-year sobriety pathway preoperatively. Primary outcomes included the presence of any complication, deep infection, and reoperation. Bivariable analyses were used to compare outcomes with demographic and health risk factors. A multivariate analysis was performed to identify independent risk factors. RESULTS Adverse outcomes were more common in patients with higher rates of substance abuse, mental illness, and infection with human immunodeficiency virus (HIV) and hepatitis C virus (HCV). Substance abuse alone was not an independent risk factor for the occurrence of complications, but infections with HIV and HCV were. In the substance abuse subgroup, with its higher prevalence of risk factors, complications were more frequent (31.1% vs 16.4%, P = .0009), and, in particular, deep infections (5.8% vs 1.8%, P = .0256). CONCLUSIONS Specific risk factors were associated with short-term complications in safety net arthroplasty patients. Despite having completed a preoperative sobriety pathway, substance abuse patients had more complications than did others. However, substance abuse alone was not an independent risk factor for adverse surgical outcomes. Other factors, notably HCV and HIV infection that were more common in patients with substance abuse, were most closely associated with adverse outcomes.

Abstract
INTRODUCTION Due to advancement in treatment against human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV), the prevalence of this patient population electing to undergo total joint arthroplasty (TJA) is increasing. Current literature is scarce and conflicting especially when evaluating long-term surgical complications. The purpose of this study is to assess the postoperative medical and surgical complications following TJA in these patient populations. METHODS Using a nationwide database between 2005 and 2012, 4 cohorts were created: patients with HIV, HCV, HBV, and HIV and HBV or HCV who underwent TJA. Cohorts were matched to a control group by age, gender, and Charlson Comorbidity Index. Thirty-day and 90-day medical complications and 90-day and 2-year surgical complications were evaluated using odds ratios with 95% confidence intervals. RESULTS Following TJA, patients with HCV or HBV had increased risk of pneumonia, sepsis, joint infection, and revision surgery at 90 days and 2 years. Patients with HIV did not have increased risk of infection at 90 days and 2 years but did have increased risk of revision at 90 days (odds ratio 3.21, 95% confidence interval 1.31-7.84) following total hip arthroplasty. CONCLUSIONS Patients with HIV, HBV, or HCV have an overall increased risk of postoperative medical and surgical complications following TJA. Patients with HBV or HCV are at risk of more complications than patients with HIV especially for infection within 90 days after TJA. Patients with HIV are at risk of mechanical complications but do not appear to be at significant risk for infection following total hip arthroplasty.

Abstract
RATIONALE Refractory immune thrombocytopenic purpura (RITP) manifests as low platelet count, with a high risk of hemorrhage, treatment difficulty, and high mortality. Total hip arthroplasty (THA) in RITP is rarely reported. This study aimed to evaluate multiple THAs or revision total hip arthroplasties (RTHAs) in RITP. PATIENT CONCERNS The male patient with RITP was 54-year-old patient and hospitalized on September 21, 2009, with the main complaint of bilateral hip pain after traveling for 2 weeks. The patient had a history of ITP for 16-years, with no response to hormone therapy (after adequate hormone therapy, platelet count persistently remained below 30 × 10/L). Two year prior to visit, the patient underwent splenectomy, and postoperative platelet persistently fluctuated around 10 to 20 × 10/L. The patient did not undergo regular reexaminations, and declined immunosuppressants. DIAGNOSES Femoral neck fracture; Refractory immune thrombocytopenic purpura (RITP). INTERVENTIONS A RITP patient with femoral neck fracture received 2 THAs and 1 RTHA. First THA indication was significant left dislocation of Garden III type. RTHA was performed following prosthetic loosening after left total hip arthroplasty. The second THA was prompted by non-healing of the old fracture, significant pain, and a low Harris score. Platelet count remained <20 × 10/L, and conventional drugs, splenectomy, and platelet transfusion had no effects. A large gamma-globulin dose was administered preoperatively. When platelet increased to 75 × 10/L, 2 THAs and 1 RTHA were successfully completed. OUTCOMES Postsurgery, conventional management was applied; no severe complications occurred. The wound was well healed, with platelet count reduced to <15 × 10/L at hospital discharge. The patient recovered, with a Harris score >80 at 1 year postsurgery. LESSONS Extremely low platelet count is a contraindication of surgery. In this patient, preoperative platelet count was <100 × 10/L. Extended disease course and multiple operations lowered platelet count, and increased risk in surgery. However, high postoperative gamma-globulin dose impacted therapy, and all surgeries were successful, with no severe complications. The wound healed well, and the quality of life was significantly improved, demonstrating the feasibility and safety of this surgery. Multiple THA or RTHA surgeries are feasible and safe for RITP patients.

Abstract
STUDY DESIGN Retrospective review. OBJECTIVE To investigate rates of in-hospital postsurgical complications among hepatitis C-infected patients after cervical spinal surgery in comparison with uninfected patients and determine independent risk factors. SUMMARY OF BACKGROUND DATA Studying hepatitis C virus (HCV) as a possible risk factor for cervical spine postoperative complications is prudent, given the high prevalence of cervical spondylosis and HCV in older patients. Spine literature is limited with respect to the impact of chronic HCV upon complications after surgery. MATERIALS AND METHODS Patients who underwent cervical spine surgery for cervical radiculopathy (CR) or cervical myelopathy (CM) from 2005 to 2013 were retrospectively reviewed using the Nationwide Inpatient Sample database. Patients were divided into CR and CM groups, with comparative subgroup analysis of HCV and no-HCV patients. Univariate analysis compared demographics and complications. Binary logistic stepwise regression modeling identified any independent outcome predictors (covariates: age, sex, Deyo score, and surgical approach). RESULTS In total, 227,310 patients (HCV: n=2542; no-HCV: n=224,764) were included. From 2005 to 2013, HCV infection prevalence among all cervical spinal fusion cases increased from 0.8% to 1.2%. HCV patients were more likely to be African American or Hispanic and have Medicare and/or Medicaid (all P<0.001). Overall complication rates among HCV patients with CR or CM increased, specifically related to device (CR: 3.1% vs. 1.9%; CM: 2.9% vs. 1.3%), hematoma/seroma (CR: 1.1% vs. 0.4%; CM: 1.8% vs. 0.8%), and sepsis (CR: 0.4% vs. 0.1%; CM: 1.1% vs. 0.5%) (all P≤0.001). Among CR and CM patients, HCV significantly predicted increased complication rates [odds ratio (OR): 1.268; OR: 1.194], hospital stay (OR: 1.738; OR: 1.861), and hospital charges (OR: 1.516; OR: 1.732; all P≤0.044). CONCLUSIONS HCV patients undergoing cervical spinal surgery were found to have increased risks of postoperative complications and increased risk associated with surgical approach. These findings should augment preoperative risk stratification and counseling for HCV patients and their spine surgeons. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND A paucity of data exists regarding long-term outcomes among patients with hepatitis C who undergo total hip arthroplasty (THA) and total knee arthroplasty (TKA). METHODS We queried a database for patients with hepatitis C who underwent THA and TKA. We then identified their rates of several postoperative complications and compared them with the same rates among mutually exclusive matched control cohorts. RESULTS Patients with hepatitis C who underwent THA and TKA had higher rates of infection, aseptic revision surgery, medical complications, and blood transfusion compared with matched control patients. DISCUSSION Our findings suggest that patients with hepatitis C who undergo THA and TKA are at increased risk of experiencing several postoperative complications, which could mean a substantial increase in the cost of care. CONCLUSIONS Further research is needed to establish quantifiable associations between hepatitis C and postoperative complications among patients with the disease who undergo total joint arthroplasty.

Does Hepatitis C Affect the Clinical and Patient-Reported Outcomes of Primary Total Hip Arthroplasty at Midterm Follow-Up? J Arthroplasty 2017; 32:2779-2782. [PMID: 28478187 DOI: 10.1016/j.arth.2017.04.001] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2017] [Revised: 03/21/2017] [Accepted: 04/02/2017] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND It is estimated that 3%-6% of orthopedic patients, many of whom may undergo lower extremity total joint arthroplasty, are infected with hepatitis C. The purpose of this study was to assess the outcomes of patients with hepatitis C who undergo total hip arthroplasty (THA) in comparison with a matched control cohort in terms of (1) patient-reported outcomes, (2) implant survivorship, and (3) complications. METHODS Fifty-four hips in 49 hepatitis C-infected patients who underwent a primary THA between 2002 and 2011 were reviewed. This included 10 women and 39 men who had a mean age of 57 years and a mean 6.5-year follow-up. These patients were matched to 163 THAs (148 patients) who did not have this disease and underwent a THA during the same period. We compared implant survivorship, complication rates, Harris hip scores, and University of California, Los Angeles, activity scores. Radiographs were evaluated for loosening, fracture, malalignment, and osteolysis. RESULTS The implant survivorship in the hepatitis C-infected patients and comparison group was 96.2% and 98.7%, respectively. The risk of revision surgery in the hepatitis C cohort was 3-fold higher than the comparison group; however, this difference was not significant (P = .26). The hepatitis C-infected cohort had a higher risk of surgical complications (odds ratio = 6.5; P = .034). There were no differences in postoperative Harris hip scores or University of California, Los Angeles, activity scores between the cohorts. CONCLUSION Hepatitis C patients can achieve good implant survivorship and clinical outcomes after THA. However, these patients may be at an increased risk for surgical complications and revision rate.

Abstract
INTRODUCTION The impact of hepatitis C virus (HCV) infection on outcomes following major orthopaedic interventions, such as joint arthroplasty or spine surgery, has not been effectively studied in the past. Most prior studies are impaired by small samples, limited surveillance for adverse events, or the potential for selection bias to confound results. In this context, we sought to evaluate the impact of HCV infection on 90-day outcomes following joint arthroplasty or spine surgery using propensity-matched techniques. MATERIALS AND METHODS This study utilized 2006-2014 claims from TRICARE insurance. Adults who received spine surgical procedures, total knee and hip arthroplasty were identified. Covariates included demographic factors, a diagnosis of HCV and medical co-morbidities defined by International Classification of Disease-9th revision (ICD-9) code. Outcomes consisted of 30- and 90-day mortality, complications and readmission. A propensity score was used to balance the cohorts with logistic regression techniques employed to determine the influence of HCV infection on post-operative outcomes. RESULTS The propensity-matched cohort consisted of 2262 patients (1131 with and without HCV). Following logistic regression, patients with HCV were found to have increased odds of 30-day complications (OR 1.87; 95% CI 1.33, 2.64; p < 0.001), 90-day complications (OR 1.55; 95% CI 1.16, 2.08; p = 0.003) and 30-day readmission (OR 1.46; 95% CI 1.04, 2.05; p = 0.03). CONCLUSION HCV infection was found to increase the risk of complication and readmission following spine surgery and total joint arthroplasty. Patients should be counseled on their increased risk prior to surgery. Health systems that treat a higher percentage of patients with HCV need to consider the increased risk of complications and readmission when negotiating with insurance carriers.

Abstract
BACKGROUND Periprosthetic joint infection (PJI) after total joint arthroplasty (TJA) is a serious complication with multiple etiologies. Prior spine literature has shown that later cases in the day were more likely to develop surgical site infection. However, the effect of case order on PJI after TJA is unknown. This study aims to determine the influence of case order, prior infected case, and terminal cleaning on the risk for a subsequent PJI. METHODS A retrospective, single-institution study was conducted on 31,499 TJAs performed from 2000 to 2014. Case order was determined by case start times per date within the same operating room. PJI was defined by the Musculoskeletal Infection Society criteria. Logistic regression was used to determine risk factors for a subsequent PJI. RESULTS Noninfected cases followed an infected case in 92 of 31,499 cases (0.29%) and were more likely to develop PJI (adjusted odds ratio [OR], 2.43; P = .029). However, terminal cleaning after infected cases did not affect the risk for PJI in cases the following morning (OR, 1.42; P = .066). Case order had an OR of 0.98 (P = .655), implying that later cases did not have a higher likelihood of infection. CONCLUSION Although surgical case order is not an independent risk factor for subsequent PJI, TJA cases following an infected case in the same room on the same day have a higher infection risk. Despite improved sterile technique and clean air operating rooms, the risk of contaminating a TJA with pathogens from a prior infected case appears to be high. Terminal cleaning appears to be effective in reducing the bioburden in the operating room.

Abstract
BACKGROUND Total hip arthroplasty (THA) costs are a source of great interest in the currently evolving health care market. The initiation of a bundled payment system has led to further research into costs drivers of this commonly performed procedure. One aspect that has not been well studied is the effect of comorbidities on the reimbursements of THA. The purpose of this study was to determine if common medical comorbidities affect these reimbursements. METHODS A retrospective, level of evidence III study was performed using the PearlDiver supercomputer to identify patients who underwent primary THA between 2007 and 2015. Patients were stratified by medical comorbidities and compared using the analysis of variance for reimbursements of the day of surgery, and over the 90-day postoperative period. RESULTS A cohort of 250,343 patients was identified. Greatest reimbursements on the day of surgery were found among patients with a history of cirrhosis, morbid obesity, obesity, chronic kidney disease (CKD) and hepatitis C. Patients with cirrhosis, hepatitis C, chronic obstructive pulmonary disease, atrial fibrillation, and CKD incurred in the greatest reimbursements over the 90-day period after surgery. CONCLUSION Medical comorbidities significantly impact reimbursements, and inferentially costs, after THA. The most costly comorbidities at 90 days include cirrhosis, hepatitis C, chronic obstructive pulmonary disease, atrial fibrillation, and CKD.

Abstract
BACKGROUND Hemophilic pseudotumor (HPT) is a rare disease with many challenges. Only a few reports on surgical treatment for HPT have been published. METHODS The cases of 23 patients with HPT who had surgical treatment from July 1996 to December 2014 were retrospectively reviewed. Demographic data, blood loss and transfusion during surgery, outcomes, and complications after surgery were analyzed. RESULTS Eleven patients underwent HPT resection; 4 underwent HPT excision, allograft transplantation, and absorbable screw fixation; 3 had HPT resection and metallic internal fixation; 2 had HPT resection, autogenous fibular grafting, and absorbable screw fixation; 2 underwent curettage and bone-grafting; and 1 patient received above-the-knee amputation. The average age (and standard deviation) of the patients at the time of surgery was 31.9 ± 12.8 years (range, 6 to 54 years) with an average follow-up of 5.3 ± 4.7 years (range, 1.1 to 19.6 years). The median duration of the surgery was 157 minutes (range, 90 to 315 minutes). The median amount of blood loss during surgery was 800 mL (range, 100 to 4,000 mL). Three patients (13%) had a postoperative infection, 2 (8.7%) had recurrence of HPT, and another 2 patients had fracture nonunion. CONCLUSIONS Surgical treatment of HPT with a modified protocol of coagulation factor replacement is safe and effective. It should be recommended for patients with HPT who have progressive enlargement of the mass, recurrent and massive bleeding, spontaneous perforation, bone erosion, or compression of surrounding tissues or who have had failure of conservative treatment.

Strategies to Prevent Periprosthetic Joint Infection After Total Knee Arthroplasty and Lessen the Risk of Readmission for the Patient. J Am Acad Orthop Surg 2017; 25 Suppl 1:S13-S16.

Abstract
There is yet to be a standardized total knee arthroplasty (TKA) surgical protocol that has been studied to a sufficient degree to offer evidence-based practices regarding infection and readmission prevention. Although high-level evidence is often sought to provide guidance concerning protocol- and process-level decisions, the literature is often confusing and nondefinitive in its conclusions and recommendations regarding periprosthetic joint infection and readmission prevention. Areas of study that require further investigation include the following: the role of patient optimization and preoperative mitigation of risk; perioperative antibiotics; operating room environment; blood management; operative techniques, implants, and infection prevention measures; wound care management; and post acute care. Patient-associated modifiable risk must be optimized to decrease poly joint infection rates after TKA. Protocol measures for TKA need to be standardized, and evidence-based practice measures need to be validated.

Is Hepatitis C Infection Associated With a Higher Risk of Complications After Total Shoulder Arthroplasty? Clin Orthop Relat Res 2016; 474:2664-2669. [PMID: 27448222 PMCID: PMC5085932 DOI: 10.1007/s11999-016-4979-9] [Citation(s) in RCA: 62] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2016] [Accepted: 07/07/2016] [Indexed: 01/31/2023]
Abstract
BACKGROUND Despite recent advances in the treatment of hepatitis C, it is estimated that nearly 4 million Americans have a chronic form of the disease. Although research in lower-extremity arthroplasty suggests patients with hepatitis C are at risk for increased complications, including postoperative bleeding, acute postoperative infection, and general medical complications, no similar studies have investigated this question in patients undergoing total shoulder arthroplasty (TSA). QUESTIONS/PURPOSES We asked whether there is an increased risk of postoperative complications after TSA among patients who have hepatitis C, and if so, what complications in particular seem more likely to occur in this population? METHODS Patients who underwent TSA, including anatomic or reverse TSA, were identified in the PearlDiver database using ICD-9 procedure codes. This is a for-fee insurance patient-records database that contains more than 100 million individual patient records from 2005 to 2012. The Medicare data in the database are the complete 100% Medicare Standard Analytical File indexed to allow for patient tracking with time. Patients with hepatitis C who underwent shoulder arthroplasty then were identified using ICD-9 codes. Patients with hepatitis B coinfection or HIV were excluded. A control cohort of patients without hepatitis C who underwent TSA was created and matched to the study cohort based on age, sex, obesity, and diabetes mellitus. A total of 1466 patients with hepatitis C and 21,502 control patients were included. The two cohorts were statistically similar in terms of sex (53% females in study and control groups), age (nearly ½ of each cohort younger than 65 years), obesity (approximately 17% of each cohort were obese), diabetes (approximately 40% of each cohort had diabetes), and followup of each cohort occurred throughout the length of the database from 2005 to 2012. Postoperative complications were assessed using ICD-9 and Current Procedural Terminology codes and compared between cohorts. RESULTS Patients with hepatitis C, when compared with matched control subjects, had greater odds of infection within 3 months (odds ratio [OR], 1.7; 95% CI, 1.1-2.6; p = 0.015), 6 months (OR, 1.7; CI, 1.3-2.4; p = 0.001), and 1 year (OR, 2.1; CI, 1.7-2.7; p < 0.001); revision TSA within 1 year (OR, 1.5; CI, 1.1-2.9; p = 0.008) and 2 years (OR, 1.6; CI, 1.2-2.0; p = 0.001), dislocation within 1 year (OR, 1.6; CI, 1.2-2.2; p < 0.001); postoperative fracture within 1 year (OR, 1.8; CI, 1.2-2.6; p = 0.002); systemic or medical complications within 3 months (OR, 1.3; CI, 1.0-1.6; p = 0.022); and blood transfusion within 3 months (OR, 1.7; CI, 1.4-1.9; p < 0.001). CONCLUSIONS Hepatitis C is associated with an increased risk for complications after TSA, including infection, dislocation, fracture, revision TSA, systemic complications, and blood transfusion compared with matched control subjects. Although this study is able to identify increased odds of complications in patients with hepatitis C, the mechanism by which these occur is likely not solely related to the virus, and is more likely related to a higher degree of case complexity in addition to other postoperative socioeconomic factors.

Abstract
BACKGROUND CONTEXT The adverse impact of chronic liver diseases, including chronic hepatitis and cirrhosis, on outcomes following orthopedic surgery has been increasingly recognized in recent years. The impact of these conditions on acute outcomes following spinal trauma remains unknown. STUDY DESIGN This is a cohort control study that uses patient records in the Massachusetts Statewide Inpatient Dataset (2003-2010). PURPOSE The study aimed to evaluate whether chronic liver disease increased the odds of mortality, complications, failure to rescue (FTR), reoperation, and hospital length of stay (LOS) following cervical spine trauma. PATIENT SAMPLE The sample is composed of 10,841 patients with cervical spine trauma. OUTCOME MEASURES Posttreatment morbidity, mortality, reoperation, and LOS were the outcome measures. METHODS Differences between patients with and without chronic liver disease were evaluated using chi-square or Wilcoxon rank-sum tests. Logistic and negative binomial regression techniques were used to adjust for confounders, including whether a surgical intervention was performed. Receiver operator characteristic curves were used to assess final model discrimination. RESULTS There were 117 patients with chronic liver disease identified in the cohort. The rate of surgical intervention for cervical trauma was not significantly different between patients with and without chronic liver disease (odds ratio [OR]: 0.82, 95% confidence interval [CI]: 0.52-1.29). Mortality (OR: 2.12, 95% CI: 1.23-3.66), FTR (OR: 2.86, 95% CI: 1.34-6.11), complications (OR: 1.65, 95% CI: 1.12-2.45), and LOS (regression coefficients: 0.31, 95% CI: 0.14-0.48) were all significantly increased for patients with chronic liver disease in final adjusted models that controlled for differences in case-mix and whether a surgical procedure was performed. Final models explained approximately 72% of the variation in mortality and FTR. CONCLUSIONS Our novel findings indicate that patients with chronic liver disease may be at elevated risk of posttreatment morbidity and mortality following cervical spine trauma. Medical comanagement in the acute period following injury and optimization before surgery may diminish the potential for adverse events.

Early Complications in Hip and Knee Arthroplasties in a Safety Net Hospital vs a University Center. J Arthroplasty 2016; 31:754-8. [PMID: 26654489 DOI: 10.1016/j.arth.2015.10.031] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/04/2015] [Revised: 09/30/2015] [Accepted: 10/23/2015] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND Indigent populations face unique challenges that may increase surgical risk and adversely affect the outcomes of hip and knee arthroplasties. This study examines whether there is a difference in early postoperative complications in patients treated in a safety net hospital and in a nearby university center. METHODS A retrospective review was undertaken of 533 consecutive hip and knee arthroplasties performed by a single experienced surgeon in a safety net hospital and in a university medical center from 2008 to 2012. Patients were followed for a minimum of 2 years. The primary outcomes evaluated were total complications, deep infections, and reoperations. Statistical comparison of the data from the 2 patient groups was carried out using Fisher exact test. RESULTS Despite the lower percentage of index revision procedures in the safety net group (8% vs 20.5%; P = .0003), the incidence of adverse outcomes was higher in this group than in the university group: for total complications, 12.3% vs 4.9% (P = .003); for deep infections, 3.2% vs 0.6% (P = .025); and for reoperations, 7.5% vs 2.6% (P = .009). For primary procedures in particular, differences in the incidences of these outcomes were even more significant. CONCLUSIONS In this study, early complications were more frequent in patients who underwent hip and knee arthroplasties in a safety net hospital compared with those who underwent the same procedures in a nearby university center. Future prospective studies are warranted to determine which patient-related or care process-related factors should be optimized to improve arthroplasty outcomes in vulnerable, safety net populations.
