ABSTRACT

Background: Cannabis use may be increasing as countries legalize it and it becomes socially acceptable. A history of cannabis use may increase risk of complications after various kinds of surgery and compromise functional recovery. Here we systematically reviewed and meta-analyzed available evidence on how history of cannabis use affects recovery after hip or knee arthroplasty (THA/TKA). Methods: The PubMed, EMBASE, and Web of Science databases were comprehensively searched and studies were selected and analyzed in accordance with the PRISMA guidelines. The methodological quality of included studies was assessed based on the Newcastle-Ottawa Scale, while quality of evidence was evaluated according to the "Grading of recommendations assessment, development, and evaluation" system. Data on various outcomes were pooled when appropriate and meta-analyzed. Results: The systematic review included 16 cohort studies involving 5.91 million patients. Meta-analysis linked history of cannabis use to higher risk of the following outcomes: revision (RR 1.68, 95% CI 1.31-2.16), mechanical loosening (RR 1.77, 95% CI 1.52-2.07), periprosthetic fracture (RR 1.85, 95% CI 1.38-2.48), dislocation (RR 2.10, 95% CI 1.18-3.73), cardiovascular events (RR 2.49, 95% CI 1.22-5.08), cerebrovascular events (RR 3.15, 95% CI 2.54-3.91), pneumonia (RR 3.97, 95% CI 3.49-4.51), respiratory failure (RR 4.10, 95% CI 3.38-4.97), urinary tract infection (RR 2.46, 95% CI 1.84-3.28), acute kidney injury (RR 3.25, 95% CI 2.94-3.60), venous thromboembolism (RR 1.48, 95% CI 1.34-1.63), and deep vein thrombosis (RR 1.42, 95% CI 1.19-1.70). In addition, cannabis use was associated with significantly greater risk of postoperative transfusion (RR 2.23, 95% CI 1.83-2.71) as well as higher hospitalization costs. Conclusion: History of cannabis use significantly increases the risk of numerous complications and transfusion after THA or TKA, leading to greater healthcare costs. Clinicians should consider these factors when treating cannabis users, and pre-surgical protocols should give special consideration to patients with history of cannbis use.

ABSTRACT

INTRODUCTION: The increase in hip arthroplasties predicts a rise in periprosthetic fractures in Morocco, posing challenges for orthopedic surgeons. Therapeutic strategies vary considerably, highlighting the absence of a universally accepted treatment protocol. AIM: To analyze the management of per-prosthetic hip fractures, while addressing the challenges associated with them. METHODS: This was a retrospective study, conducted in the trauma-orthopedics department between December 2015 and November 2022. Nineteen patients who presented to the hospital with fractures around a hip prosthesis were included. RESULT: Nineteen periprosthetic fractures were observed. The majority of patients (68%) were women, with an average age of 68. The Vancouver classification showed that 52.6% of the fractures were type B1, and 21.1% type C, while the other fracture types were distributed differently. These fractures were mainly associated with diagnoses such as femoral neck fracture (63.2%) and coxarthrosis (31.6%). We observed variations in treatment recommendations and results between the different series analyzed. We noted discrepancies with certain series concerning fracture types and therapeutic choices. However, in our series, we achieved satisfactory results, with successful consolidation and the absence of complications in all patients. CONCLUSION: These results underline the importance of an individualized approach to fracture management, taking into account the specificities of each case.

ABSTRACT

BACKGROUND: Several studies have compared the pros and cons of simultaneous bilateral versus staged bilateral hip and knee replacement but the outcomes of these two surgical options remains a matter of controversy. This study aimed to evaluate demographic features, incidence and hospitalization rates of bilateral one stage total hip and knee arthroplasty in Italy. METHODS: The Italian Ministry of Health's National Hospital Discharge Reports (SDO) were used to gather data. This study referred to the adult population (+ 20 years of age) from 2001 to 2015 for hip arthroplasty and from 2001 to 2016 for knee arthroplasty. RESULTS: Overall, 1,544 bilateral simultaneous hip replacement were carried out. The incidence rate was 0.21 cases per 100,000 adult Italian residents. Male/female ratio was 1.1. The average days of hospital stay was 11.7 ± 11.8 days. The main primary codified diagnosis was: osteoarthrosis, localized, primary, pelvic region and thigh (ICD code: 715.15). 2,851 bilateral simultaneous knee replacement were carried out. The incidence rate was 0.37 cases per 100,000 adult Italian residents. Male/female ratio was 0.6. The average days of hospital stay was 7.7 ± 5.8 days. The main primary codified diagnosis was: osteoarthrosis, localized, primary, lower leg (ICD code: 715.16). CONCLUSIONS: The burden of hip and knee osteoarthrosis as a leading cause of bilateral joint replacement is significant in Italy. The national registers' longitudinal analysis may provide data for establishing international guidelines regarding the appropriate indications for one stage bilateral simultaneous hip or knee replacement versus two stage.

ABSTRACT

BACKGROUND: Knee osteoarthritis (OA) has been quite consistently associated with high physical workload and specific physical factors at work, while for hip OA, fewer studies are available, which still indicate possible associations with heavy lifting and physical workload. The objective of the study was to assess the association between exposure to workplace physical factors and incidence of knee and hip arthroplasty, as markers of severe OA in these joints. METHODS: The study population was composed of employees 25-60 years who participated in the Turin 2011 census. For each job held since 1995, exposure to physical factors was assigned to individuals in the cohort through a Job-Exposure Matrix constructed from the Italian O*NET database. Using Poisson regression models, the incidence of knee and hip arthroplasty for OA, identified through hospitalizations from 2012 to 2018, was examined in relation to cumulative exposure to 7 different physical hazards and a composite indicator of physical workload constructed from 17 physical factors (Ergo-Index). RESULTS: The risk of knee OA was significantly increased in the highest cumulative exposure quartile of physical workload (incidence rate ratio = 1.98, 95% confidence interval: 1.24-3.16) and of all single hazards examined, compared to the lowest quartile, with significant trends in risk with increasing exposure. In contrast, no association was found with hip OA, whose relative risks were close to or below one in all higher-exposure quartiles of physical workload and of each single hazard. CONCLUSIONS: Our results indicate that exposure to physical hazards at work increases the likelihood of developing knee OA, but not hip OA.

ABSTRACT

BACKGROUND: As volume of total hip arthroplasty (THA) continues to increase, the utilization and availability of in-traoperative advanced technologies to arthroplasty surgeons continues to rise as well. Our primary goal was to determine whether the use of a mini navigation technology extended operative times and secondarily if it affected postoperative outcomes following elective THA. METHODS: A single-institution total joint arthroplasty da-tabase was utilized to identify adult patients who underwent elective THA from 2017 to 2019. Baseline demographic data along with surgical operative time, length of stay (LOS) and discharge disposition were collected. The Activity Measure for Post-Acute Care (AM-PAC) was used to determine physi-cal therapy progress. RESULTS: A total of 1,162 THAs were performed of which 69.1% (803) used navigation while 30.9% (359) did not. Baseline demographics including age, sex, body mass index (BMI), insurance, and smoking status were not statistically different between groups. The operative time was shorter in the navigation group compared to THA without navigation (115.1 vs. 118.9 min, p < 0.0001). Mean LOS was signifi-cantly shorter in the navigation THA group as compared to THA without navigation (2.1 vs. 2.6 days, p < 0.0001). Postoperative AM-PAC scores were higher in the navigation group on postoperative day 1 as compared to patients with-out navigation (18.87 vs. 17.52, p < 0.0001). Additionally, a greater percentage of patients were discharged directly home after THA with navigation as compared to THA without navigation (89.54% vs. 83.57%, p < 0.0001). CONCLUSION: Our study demonstrates that hip navigation technology in the setting of THA is associated with reduced operative times and higher AM-PAC mobilization scores. Hip mini navigation technology shortens operative times while improving early patient outcome scores in association with shorter LOS and greater home-based discharge.

ABSTRACT

BACKGROUND AND PURPOSE: We aimed to examine the association between socioeconomic status (SES) markers and opioid use after primary total hip arthroplasty (THA) due to osteoarthritis, and whether sex, age, or comorbidities modify any association. METHODS: Using Danish databases, we included 80,038 patients undergoing primary THA (2001-2018). We calculated prevalences and prevalence ratios (PRs with 95% confidence intervals [CIs]) of immediate post-THA opioid use (≥ 1 prescription within 1 month) and continued opioid use (≥ 1 prescription in 1-12 months) among immediate opioid users. Exposures were individual-based education, cohabitation, and wealth. RESULTS: The prevalence of immediate opioid use was ~45% in preoperative non-users and ~60% in preoperative users (≥ 1 opioid 0-6 months before THA). Among non-users, the prevalences and PRs of continued opioid use were: 28% for low vs. 21% for high education (PR 1.28, CI 1.20-1.37), 27% for living alone vs. 23% for cohabiting (PR 1.09, CI 1.04-1.15), and 30% for low vs. 20% for high wealth (PR 1.43, CI 1.35-1.51). Among users, prevalences were 67% for low vs. 55% for high education (1.22, CI 1.17-1.27), 68% for living alone vs. 60% for cohabiting (PR 1.10, CI 1.07-1.12), and 73% for low wealth vs. 54% for high wealth (PR 1.32, CI 1.28-1.36). Based on testing for interaction, sex, age, and comorbidity did not statistically significant modify the associations. Nevertheless, associations were stronger in younger patients for all SES markers (mainly for non-users). CONCLUSION: Markers of low SES were associated with a higher prevalence of continued post-THA opioid use. Age modified the magnitude of the associations, but it was not statistically significant.

ABSTRACT

Hip and knee arthroplasties are mostly successful procedures; however, patient injuries may occur and should be reported to Löf, the Swedish patient insurance. This study investigated the incidence of patient injuries after primary total hip and knee arthroplasty in the Swedish regions, differences in incidence depending on annual surgical volume, and types of approved injuries. Approved patient injuries were related to the total number of hip and knee arthroplasties registered in the Swedish Arthroplasty Register 2012-2021. The national incidence was 11.4 and 8.1 per 1,000 hip and knee arthroplasties respectively and varied in the regions from 30.4 to 4.9 and 15.4 to 5.4 per 1,000 hip and knee arthroplasties respectively. Orthopedic departments with higher annual volumes of performed arthroplasties had a lower proportion of patient injuries. Infection was the most common patient injury, followed by nerve lesions and mechanical complications. The differences may be due to underreporting and varying quality of care in the regions. A centralization of hip and knee arthroplasties may be beneficial.

ABSTRACT

Importance: The past several decades have witnessed substantial changes in treatments that are particularly relevant for older patients. Objectives: To assess changes in national-level incidence rates of fracture- and musculoskeletal-related (ie, arthritis-related) hip replacement procedures for individuals aged 40 to 104 years over a 23-year period in Denmark. Design, Setting, and Participants: This cohort study used national Danish health registers to include the Danish population aged 40 to 104 years from January 1, 1996, to December 31, 2018. Data were analyzed from May 31, 2022, to February 14, 2024. Main Outcomes and Measures: Age- and period-specific incidence rates of hip fracture and hip replacement stratified on fracture-related vs arthritis-related indication. Results: From 1996 to 2018, a total of 3 664 979 individuals were followed up for a mean (SD) of 14.6 (7.7) years, resulting in a follow-up time of 53 517 861 person-years and 158 982 (first) hip fractures, of which 42 825 involved fracture-related hip replacement procedures. A further 104 422 individuals underwent arthritis-related hip replacement. During the first 2 decades of the 21st century, hip fracture rates declined by 35% to 40% for individuals aged 70 to 104 years, and the proportion of the population undergoing fracture-related hip replacement increased by 50% to 70%, with modest variation across those aged 75 to 99 years. Rates of arthritis-related hip replacements peaked for individuals aged 75 to 79 years, but with the largest relative rate increase (75%-100%) occurring for those aged 80 to 94 years, primarily from 2001 to 2015, whereafter it remained nearly unchanged. The decline in rates of arthritis-related hip replacement after 75 to 79 years of age was gradual and did not suggest an upper age limit for access to arthritis-related hip replacement. Conclusions and Relevance: The findings of this cohort study suggest that during the past several decades in Denmark, the incidence of hip fractures declined by 35% to 40% among patients aged 80 to 104 years, while the proportion receiving fracture-related hip replacement remained relatively constant after 75 years of age. During the first decades of the 21st century, arthritis-related hip replacement incidence increased by 50% to 100% among older patients and stabilized hereafter, with no apparent cutoff age for this type of procedure. These patterns indicate a positive overall trend with declining hip fracture incidence over the last decades in Denmark, and the observed hip replacement incidence suggests that age is currently not a major determining factor guiding this type of surgery.

ABSTRACT

INTRODUCTION: The importance of identifying how patients choose their healthcare providers has grown with the prevalence of consumer-centric health insurance plans. There is currently a lack of studies exploring the factors associated with how patients select their hip and knee joint arthroplasty surgeons. The purpose of this study was to determine how patients find their arthroplasty providers and the relative importance of various arthroplasty surgeon characteristics. METHODS: An electronic mail survey was sent to 3522 patients who had visited our institution for an arthroplasty surgeon office visit between August 2022 and January 2023. The survey consisted of multiple-choice questions, which aimed to inquire about the patients' referral sources for their current arthroplasty surgeon. In addition, patients were requested to rate the significance of 22 surgeon-related factors, on a scale of 1 (Not Important At All) to 5 (Very Important), in choosing their arthroplasty surgeon. RESULTS: Of the 3522 patients that received the survey, 538 patients responded (15.3%). The most common referral sources were physician referral (50.2%), family/friend referral (27.7%), and self-guided research (24.5%). Of those that were referred by a physician, 54.4% of respondents were referred by another orthopaedic provider. Patients rated board certification (4.72 ± 0.65), in-network insurance status (4.66 ± 0.71), fellowship training (4.50 ± 0.81), bedside manner/personality (4.32 ± 0.86), and facility appearance (4.26 ± 0.81) as the five most important factors in picking an arthroplasty surgeon. Television (1.42 ± 0.83), print (1.50 ± 0.88), and online (1.58 ± 0.93) advertisements, along with social media presence (1.83 ± 1.08), and practice group size (2.97 ± 1.13) were rated as the five least important factors. CONCLUSION: Patients are most likely to select an arthroplasty surgeon based on referral from other physicians, namely orthopedic surgeons, in addition to board certification status, in-network insurance, and fellowship training. Overall, these findings highlight the importance of physician credentials and reputation within the orthopaedic community in order to attract and retain patients.

ABSTRACT

BACKGROUND: American Indian and Alaska Native (AIAN) health issues are understudied despite documentation of lower-than-average life expectancy. Urgent surgery is associated with higher rates of postsurgical complications and postoperative death. We assess whether American Indian and Alaska Native (AIAN) patients in Washington State are at greater risk of requiring urgent rather than elective surgery compared with non-Hispanic Whites (NHW). METHODS: We accessed data for the period 2009-2014 from the Washington State Comprehensive Hospital Abstract Reporting System (CHARS) database, which captures all statewide hospital admissions, to examine three common surgeries that are performed both urgently and electively: hip replacements, aortic valve replacements, and spinal fusions. We extracted patient race, age, insurance status, comorbidity, admission type, and procedures performed. We then constructed multivariable logistic regression models to identify factors associated with use of urgent surgical care. RESULTS: AIAN patients had lower mean age at surgery for all three surgeries compared with NHW patients. AIAN patients were at higher risk for urgent surgery for hip replacements (OR = 1.49, 95% CI 1.19-1.88), spinal fusions (OR = 1.39, 95% CI 1.04-1.87), and aortic valve replacements (OR = 2.06, 95% CI 1.12-3.80). CONCLUSION: AIAN patients were more likely to undergo urgent hip replacement, spinal fusion, and aortic valve replacement than NHW patients. AIAN patients underwent urgent surgery at younger ages. Medicaid insurance conferred higher risks for urgent surgery across all surgeries studied. Further research is warranted to more clearly identify the factors contributing to disparities among AIAN patients undergoing urgent surgery.

ABSTRACT

BACKGROUND: Dementia is a prevalent neurological condition, yet the relationship between dementia and general anesthesia remains uncertain. The study aimed to explore the association between general anesthesia and dementia using a nationwide population-based database. METHODS: The study extracted data from Taiwan's national health insurance, which encompassed the records of one million insured residents. A total of 59,817 patients aged 65 years and above, diagnosed with osteoarthritis between 2002 and 2010, were included. Among these patients, 3277 individuals with an initial diagnosis of dementia between 2004 and 2013 were matched with non-dementia patients based on age, gender, and the date of osteoarthritis diagnosis. Following a 1:2 random matching, the case group included 2171 patients with dementia, while the control group consisted of 4342 patients without dementia. The data was analyzed using conditional and unconditional logistic regressions. RESULTS: No significant differences in the odds of dementia were found between individuals exposed to general and regional anesthesia during hip/knee replacement surgeries (OR = 1.11; 95%CI: 0.73-1.70), after adjusting for age, sex, and co-morbidities. Similarly, there were no significant differences in the odds of dementia based on different durations of anesthesia exposure (General: <2 h: OR = 0.91, 95%CI = 0.43-1.92; 2-4 h: OR = 1.21, 95%CI = 0.82-1.79; >4 h: OR = 0.39, 95%CI = 0.15-1.01; compared to no exposure. Regional: <2 h: OR = 1.18, 95%CI = 0.85-1.62; 2-4 h: OR = 0.9, 95%CI = 0.64-1.27; >4 h: OR = 0.55, 95%CI = 0.15-1.96; compared to no exposure). Likewise, no significant differences were observed in the odds of dementia based on the number of replacement surgeries (twice: OR = 0.74, 95%CI = 0.44-1.23, compared to once). CONCLUSION: Neither general anesthesia nor regional anesthesia in hip/knee surgery was associated with dementia. Different numbers and durations of anesthesia exposure showed no significant differences in the odds for dementia.

ABSTRACT

BACKGROUND: The rate of outpatient total joint arthroplasty procedures, including those performed at ambulatory surgical centers (ASCs) and hospital outpatient departments, is increasing. The purpose of this study was to analyze if type of insurance is associated with site of service (in-patient vs outpatient) for total joint arthroplasty and adverse outcomes. MATERIALS AND METHODS: We identified patients undergoing unicompartmental knee arthroplasty (UKA), total knee arthroplasty (TKA), or total hip arthroplasty (THA) using Current Procedural Terminology codes in a national administrative claims database. Eligible patients were stratified by type of insurance (Medicaid, Medicare, private). The primary outcome was site of service. Secondary outcomes included general complications, procedural complications, and revision procedures. We evaluated the associations using adjusted multivariable logistic regression models. RESULTS: We identified 951,568 patients for analysis; 46,703 (4.9%) patients underwent UKA, 607,221 (63.8%) underwent TKA, and 297,644 (31.3%) underwent THA. Overall, 9.6% of procedures were outpatient. Patients with Medicaid were less likely than privately insured patients to receive outpatient UKA or THA (UKA: odds ratio [OR], 0.729 [95% CI, 0.640-0.829]; THA: OR, 0.625 [95% CI, 0.557-0.702]) but more likely than patients with Medicare to receive outpatient TKA or THA (TKA: OR, 1.391 [95% CI, 1.315-1.472]; THA: OR, 1.327 [95% CI, 1.166-1.506]). Patients with Medicaid were more likely to experience complications and revision procedures. CONCLUSION: Differences in site of service and complication rates following hip and knee arthroplasty exist based on type of insurance, suggesting a disparity in care. Further exploration of drivers of this disparity is warranted and can inform interventions (eg, progressive value-based payments) to support equity in orthopedic services.

ABSTRACT

BACKGROUND: Previous arthroplasty utilization research predominantly examined Black and White populations within the US. This is the first known study to examine utilization and complications in poorly studied minority racial groups such as Asians and Native Hawaiian/Pacific-Islanders (NHPI) as compared to Whites. RESULTS: Data from 3304 primary total hip and knee arthroplasty patients (2011 to 2019) were retrospectively collected, involving 1789 Asians (52.2%), 1164 Whites (34%) and 320 Native Hawaiians/Pacific Islanders (NHPI) (9.3%). The 2012 arthroplasty utilization rates for Asian, White, and NHPI increased by 32.5%, 11.2%, and 86.5%, respectively, by 2019. Compared to Asians, Whites more often underwent hip arthroplasty compared to knee arthroplasty (odds ratio (OR) 1.755; p < 0.001). Compared to Asians, Whites and NHPI more often received total knee compared to unicompartmental knee arthroplasty (White: OR 1.499; NHPI: OR 2.013; p < 0.001). White patients had longer hospitalizations (2.66 days) compared to Asians (2.19 days) (p = 0.005) following bilateral procedures. Medicare was the most common insurance for Asians (66.2%) and Whites (54.2%) while private insurance was most common for NHPI (49.4%). Compared to Asians, economic status was higher for Whites (White OR 0.695; p < 0.001) but lower for NHPI (OR 1.456; p < 0.001). After controlling for bilateral procedures, NHPI had a lower risk of transfusion compared to Asians (OR 0.478; p < 0.001) and Whites had increased risk of wound or systemic complications compared to Asians (OR 2.086; p = 0.045). CONCLUSIONS: Despite NHPI demonstrating a significantly poorer health profile and lower socioeconomic status, contrary to previous literature involving minority racial groups, no significant overall differences in arthroplasty utilization rates or perioperative complications could be demonstrated amongst the racial groups examined.

ABSTRACT

BACKGROUND: Previous data suggest that obesity does not impact surgical outcomes following total knee arthroplasty performed by high-volume (HV) surgeons. However, this effect has yet to be studied in total hip arthroplasty (THA) patients. This study aimed to evaluate the impact of patient obesity on THA outcomes when surgery is performed by HV surgeons. METHODS: A retrospective analysis of patients who underwent primary, elective THA between January 2012 and December 2022 with a HV surgeon (top 25% of surgeons by number of annual primary THA) was performed. Patients were stratified by their body mass index (BMI) into 3 cohorts: BMI ≥ 40 (morbidly obese [MO]), 30 ≤ BMI < 40 (obese), and BMI < 30 (nonobese); and 1:1:1 propensity matched based on baseline characteristics. A total of 13,223 patients were evaluated, of which 669 patients were included in the final matched analysis (223 patients per group). The average number of annual THAs performed for HV surgeons was 171 cases. RESULTS: The MO patients had significantly longer surgical times (P < .001) and hospital lengths of stay (P < .001). Rates of 90-day readmissions (P = .211) and all-cause, septic, and aseptic revisions at the latest follow-up (P = .268, P = .903, and P = .168, respectively) were comparable between groups. In a subanalysis for non-HV surgeons, MO patients had a significantly greater risk of revision (P = .021) and trended toward significantly greater readmissions (P = .056). CONCLUSIONS: Clinical outcomes and complication rates after THA performed by a HV surgeon are similar regardless of patient obesity status. Patients who have MO may experience improved outcomes and reduced procedural risks if they are referred to HV surgeons. LEVEL OF EVIDENCE: III.

ABSTRACT

BACKGROUND: Academic accomplishments and demographics for presidents of hip and knee arthroplasty societies are poorly understood. This study compares the characteristics of presidents nominated to serve the Hip Society, Knee Society, and American Association of Hip and Knee Surgeons. METHODS: This was a cross-sectional study of arthroplasty presidents in the United States (1990 to 2022). Curriculum vitae and academic websites were analyzed for demographic, training, bibliometric, and National Institutes of Health (NIH) funding data. Comparisons were made between organizations and time periods (1990 to 2005 versus 2006 to 2022). RESULTS: There were 97 appointments of 78 unique arthroplasty presidents (80%). Most presidents were male (99%) and Caucasian (95%). There was 1 woman (1%) and 5 non-Caucasian presidents (2% Asian, 3% Hispanic). There were no differences in demographics between the 3 arthroplasty organizations and the 2 time periods (P > .05). Presidents were appointed at 55 ± 10 years old, which was on average 24 years after completion of residency training. Most presidents had arthroplasty fellowship training (68%), and the most common were the Hospital for Special Surgery (21%) and Massachusetts General Hospital (8%). The median h-index was 53 resulting from 191 peer-reviewed publications, which was similar between the 3 organizations (P > .05). There were 2 presidents who had NIH funding (2%), and there were no differences in NIH funding between the 3 organizations (P > .05). CONCLUSIONS: Arthroplasty society presidents have diverse training pedigrees, high levels of scholarly output, and similar demographics. There may be future opportunities to promote diversity and inclusion among the highest levels of leadership in total joint arthroplasty.

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.

ABSTRACT

PURPOSE: Anemia has been shown to be a modifiable pre-operative, patient factor associated with outcome following arthroplasty. The aims of this retrospective study were to (1) ascertain the prevalence of preoperative anemia in patients undergoing primary and revision hip and knee arthroplasty at a tertiary referral center and (2) to test the association with outcome and whether it differs between primary and revision cases. METHODS: All hip and knee primary and revision arthroplasties performed at a Canadian academic, tertiary-care, arthroplasty center between 2012 and 2017 were included in this study. The study group consisted of 5944 patients, of which 5251 were primary Total Hip and Knee Arthroplasties or Hip Resurfacings and 693 were revision arthroplasties (65% hip revisions/35% knee revisions). Anemia was classified as per WHO definition (hemoglobin < 130 g/L for men and < 120 g/L for women). All anemic patients were grouped into mild, moderate or severe anemia. Length-of-stay, perioperative transfusion-rate, 90-day readmission, overall complication rate and reoperation rates were recorded. The effect of preoperative anemia and the effect of severity of the anemia was evaluated through multivariable regression analysis controlling for relevant covariates. RESULTS: Preoperatively, 15% (786/5251) of the primary patients and 47% (322/693) of the revision arthroplasty patients were anemic preoperatively. Anemic revision patients were 3.1 times more likely (95% CI: 1.47-6.33) to obtain blood transfusions during the hospital stay, compared to a 4.9 times higher risk in primary patients. The odds ratio to sustain any postoperative complication if anemic was 1.5 times higher (95% CI: 0.73-3.16) in revision patients and 1.7 in primary cases. In addition, the 90-day readmission rate among both groups was 1.6 times higher in anemic patients. Furthermore, anemic revision patients had a 5.3 days longer length of stay (95% CI: 2.63-7.91), compared to only 1 additional day in anemic primary patients (95% CI: 0.69-1.34). CONCLUSION: In this study cohort, the prevalence of anemia in patients awaiting revision arthroplasty was 3 times higher (46.6%) than in primary arthroplasty patients (18.7%). Preoperative anemia was associated with similarly, inferior outcomes in both groups. To reduce postoperative complications and the "burden" associated with anemia, these findings strongly recommend optimizing the preoperative hemoglobin in all arthroplasty patients. However, revision patients are affected more frequently, and particular attention must therefore be taken to this growing group in the future. LEVEL OF EVIDENCE: Level III.

ABSTRACT

BACKGROUND: Inpatient total hip and total knee arthroplasty were substantially impacted by the SARS-CoV-2 (COVID-19) pandemic. We sought to characterize the transition of total joint arthroplasty (TJA) to the outpatient setting in 2 large state health systems during this pandemic. METHODS: Adult patients who underwent primary elective TJA between January 1, 2016 and December 31, 2020 were retrospectively reviewed using the New York Statewide Planning and Research Cooperative System and California Department of Health Care Access and Information datasets. Yearly inpatient and outpatient case volumes and patient demographics, including age, sex, race, and payer coverage, were recorded. Continuous and categorical variables were compared using descriptive statistics. Significance was set at P < .05. RESULTS: In New York during 2020, TJA volume decreased 16% because 22,742 fewer inpatient TJAs were performed. Much of this lost volume (46.6%) was offset by a 166% increase in outpatient TJA. In California during 2020, TJA volume decreased 20% because 34,114 fewer inpatient TJAs were performed. Much of this lost volume (37%) was offset by a 47% increase in outpatient TJA. CONCLUSIONS: This present study demonstrates a marked increase in the proportion of TJA being performed on an outpatient basis in both California and New York. In both states, despite a decrease in overall TJA volume in 2020, outpatient TJA volume increased markedly. LEVEL OF EVIDENCE: Therapeutic Level IV, Retrospective Cohort Study.

ABSTRACT

BACKGROUND: The use of the direct anterior approach (DAA) in total hip arthroplasty (THA) has steadily increased in the Netherlands since 2007. The aim of this study was to outline how the DAA has been implemented in the Netherlands. Moreover, we investigated the learning curve of the DAA at a hospital level, and explored patient characteristics of the DAA compared with other approaches and during the learning phase after implementing the DAA. METHODS: In this population-based cohort study, we included all primary THAs between 2007 and 2020 (n = 342,473) from the Dutch Arthroplasty Register. For hospitals implementing the DAA (n > 20), patients were categorized in 4 experience groups using the date of surgery: 1 to 50, 51 to 100, 101 to 150, or > 150. Subsequently, data from different hospitals were pooled and survival rates were calculated using Kaplan-Meier survival analyses. Adjusted revision rates were calculated using mixed Cox proportional hazard models (frailty). RESULTS: The use of the DAA gradually rose from 0.2% in 2007 to 41% of all primary THAs in 2020. A total of 64 (56%) hospitals implemented the DAA. However, not all hospitals continued using this approach. After implementation, the 5-year survival rate for the first 50 procedures was significantly lower (96% confidence interval [CI] 95.8 to 97.2) compared to >150 procedures (98% CI 97.7 to 98.1). Multivariable Cox hazard analyses demonstrated a higher risk of revision during the first 50 procedures compared with >150 procedures (hazard ratio 1.6, CI 1.3 to 2.0). CONCLUSIONS: The use of DAA for primary THA significantly increased. For hospitals implementing DAA, a considerable learning curve with increased revision risk was seen.

ABSTRACT

BACKGROUND: Perceived surgeon workload of performing primary and revision total hip arthroplasty (THA) and total knee arthroplasty (TKA) is challenging to quantify. The National Aeronautics and Space Administration Task Load Index (NASA TLX) survey was developed to quantify experiences following aviation and has been applied to healthcare fields. Our purposes were to 1) quantify the workload endured by surgeons who are performing primary and revision TKA and THA and 2) compare these values to their Center for Medicare & Medicaid Services (CMS) reimbursement. METHODS: A prospective cohort of 5 fellowship-trained adult reconstruction surgeons completed NASA TLX surveys following primary and revision TKA/THA cases. A total of 122 surveys consisting of 70 TKA (48 primaries and 22 revisions) and 55 THA surveys (38 primaries and 17 revisions) were completed. Patient demographics and surgical variables were recorded. Final NASA TLX workloads were compared to 2021 CMS work relative value units. RESULTS: Compared to primary TKA, revision TKA had 176% increased intraoperative workload (P < .001), 233% increased mental burden (P < .001), and 150% increased physical burden (P < .001). Compared to primary THA, revision THA had 106% increased intraoperative workload (P < .001), 96% increased mental burden (P < .001), and 91% increased physical burden (P < .001). Operative time was higher in revision versus primary TKA (118 versus 84.5 minutes, P = .05) and THA (150 versus 115 minutes, P = .001). Based upon 2021 CMS data, revision TKA and THA would need to be compensated by an additional 36% and 12.3%, respectively, to parallel intraoperative efforts. CONCLUSIONS: Revision hip and knee arthroplasty places a major mental and physical workload upon surgeons and is disproportionately compensated by CMS.
