RESUMEN
BACKGROUND: Total joint arthroplasty aims to improve quality of life and functional outcomes for all patients, primarily by reducing their pain. This goal requires clinical practice guidelines (CPGs) that equitably represent and enroll patients from all racial/ethnic groups. To our knowledge, there has been no formal evaluation of the racial/ethnic composition of the patient population in the studies that informed the leading CPGs on the topic of pain management after arthroplasty surgery. QUESTIONS/PURPOSES: Using papers included in the 2021 Anesthesia and Analgesia in Total Joint Arthroplasty Clinical Practice Guidelines and comparing them with US National census data, we asked: (1) What is the representation of racial/ethnic groups in randomized controlled trials compared with their representation in the US national population? (2) Is there a relationship between the reporting of racial/ethnic groups and year of data collection/publication, location of study, funding source, or guideline section? METHODS: Participant demographic data (study year published, study type, guideline section, year of data collection, study site, study funding, study size, gender, age, and race/ethnicity) were collected from articles cited by this guideline. Studies were included if they were full text, were primary research articles conducted primarily within the United States, and if they reported racial and ethnic characteristics of the participants. The exclusion criteria included duplicate articles, articles that included the same participant population (only the latest dated article was included), and the following article types: systematic reviews, nonsystematic reviews, terminology reports, professional guidelines, expert opinions, population-based studies, surgical trials, retrospective cohort observational studies, prospective cohort observational studies, cost-effectiveness studies, and meta-analyses. Eighty-two percent (223 of 271) of articles met inclusion criteria. Our original literature search yielded 27 papers reporting the race/ethnicity of participants, including 24 US-based studies and three studies conducted in other countries; only US-based studies were utilized as the focus of this study. We defined race/ethnicity reporting as the listing of participants' race or ethnicity in the body, tables, figures, or supplemental data of a study. National census information from 2000 to 2019 was then used to generate a representation quotient (RQ), which compared the representation of racial/ethnic groups within study populations to their respective demographic representation in the national population. An RQ value greater than 1 indicates an overrepresented group and an RQ value less than 1 indicates an underrepresented group, relative to the US population. Primary outcome measures of RQ value versus time of publication for each racial/ethnic group were evaluated with linear regression analysis, and race reporting and manuscript parameters were analyzed with chi-square analyses. RESULTS: Two US-based studies reported race and ethnicity independently. Among the 24 US-based studies reporting race/ethnicity, the overall RQ was 0.70 for Black participants, 0.09 for Hispanic participants, 0.1 for American Indian/Alaska Natives, 0 for Native Hawaiian/Pacific Islanders, 0.08 for Asian participants, and 1.37 for White participants, meaning White participants were overrepresented by 37%, Black participants were underrepresented by 30%, Hispanic participants were underrepresented by 91%, Asian participants were underrepresented by 92%, American Indian/Alaska Natives were 90% underrepresented, and Native Hawaiian Pacific Islanders were virtually not represented compared with the US national population. On chi-square analysis, there were differences between race/ethnicity reporting among studies with academic, industry, and dual-supported funding sources (χ 2 = 7.449; p = 0.02). Differences were also found between race/ethnicity reporting among US-based and non-US-based studies (χ 2 = 36.506; p < 0.001), with 93% (25 of 27) of US-based studies reporting race as opposed to only 7% (2 of 27) of non-US-based studies. Finally, there was no relationship between race/ethnicity reporting and the year of data collection or guideline section referenced. CONCLUSION: The 2021 Anesthesia and Analgesia in Total Joint Arthroplasty Clinical Practice Guidelines provide evidence-based recommendations that reflect the current standards in orthopaedic surgery, but the studies upon which they are based overwhelmingly underenroll and underreport racial/ethnic minorities relative to their proportions in the US population. As these factors impact analgesic administration, their continued neglect may perpetuate inequities in outcomes after TJA. CLINICAL RELEVANCE: Our study demonstrates that all non-White racial/ethnic groups were underrepresented relative to their proportion of the US population in the 2021 Anesthesia and Analgesia in Total Joint Arthroplasty Clinical Practice Guidelines, underscoring a weakness in the orthopaedic surgery evidence base and questioning the overall external validity and generalizability of these combined CPGs. An effort should be made to equitably enroll and report outcomes for all racial/ethnic groups in any updated CPGs.

BACKGROUND: Women orthopaedic surgeons face unique challenges during their careers. There are extremely low numbers of women in the field, particularly in the specialty of adult reconstruction. Factors contributing to low numbers of women entering this subspecialty include increased perceived physical demand relative to other fields, occupational hazards during pregnancy such as exposure to radiation and polymethylmethacrylate bone cement, concerns for work-life balance, and limited number of women within the subspecialty. The following editorial provides a framework to understand and manage the potential occupational hazards to pregnant and lactating surgeons, parental leave, and postpartum return to work. We aim to dispel any unfounded myths and provide evidence-based education that may help overcome these barriers. In doing so, we hope to encourage more women to consider adult reconstruction as a potential career. METHODS: Our primary method consisted of completing an extensive literature review on the past and current articles about the aforementioned barriers which may contribute to the low number of women entering adult reconstruction. After this literature search was completed, we composed a comprehensive editorial that provided evidence-based education and recommendations for medical professionals. CONCLUSIONS: Issues pertaining to parenthood, pregnancy, and lactation pose barriers to success for women in orthopedic surgery. These concerns may dissuade talented women from pursuing a rewarding career in adult reconstruction. Education on these issues is needed to help our early-career colleagues plan and care for their families. Clearly stated and published policies should be made available in all training programs, fellowships, and clinical practices to allow understanding and unbiased implementation. By being more inclusive, adult reconstruction will have access to the best possible surgeons, which will benefit not only patients but the field as a whole.

BACKGROUND: There is increasing appreciation of the distinction between gender and sex as well as the importance of accurately reporting these constructs. Given recent attention regarding transgender and gender nonconforming (TGNC) and intersex identities, it is more necessary than ever to understand how to describe these identities in research. This study sought to investigate the use of gender- and sex-based terminology in arthroplasty research. METHODS: The 5 leading orthopaedic journals publishing arthroplasty research were reviewed to identify the first twenty primary clinical research articles on an arthroplasty topic published after January 1, 2022. Use of gender- or sex-based terminology, whether use was discriminate, and whether stratification or adjustment based on gender or sex was performed, were recorded. RESULTS: There were 98 of 100 articles that measured a construct of gender or sex. Of these, 15 articles used gender-based terminology, 45 used sex-based terminology, and 38 used a combination of gender- and sex-based terminology. Of the 38 articles using a combination of terminology, none did so discriminately. All articles presented gender and sex as binary variables, and 2 attempted to explicitly define how gender or sex were defined. Of the 98 articles, 31 used these variables for statistical adjustments, though only 6 reported stratified results. CONCLUSIONS: Arthroplasty articles infrequently describe how gender or sex was measured, and frequently use this terminology interchangeably. Additionally, these articles rarely offer more than 2 options for capturing variation in sex and gender. Future research should be more precise in the treatment of these variables to improve the quality of results and ensure findings are patient-centered and inclusive.
RESUMEN
BACKGROUND: Advanced care planning documents provide a patient's healthcare team and loved ones with guidance on patients' treatment preferences when they are unable to advocate for themselves. A substantial proportion of patients will die within a few months of experiencing a hip fracture, but despite the importance of such documents, patients undergoing surgery for hip fracture seldom have discussions documented in the medical records regarding end-of-life care during their surgical admission. To the best of our knowledge, the proportion of patients older than 65 years treated with surgery for hip fractures who have advanced care planning documents in their electronic medical record (EMR) has not been explored, neither has the association between socioeconomic status and the presence of those documents in the EMR. Determining this information can help to identify opportunities to promote advanced care planning. QUESTIONS/PURPOSES: (1) What percentage of patients older than 65 years who undergo hip fracture surgery have completed advanced care planning documents uploaded in the EMR before or during their surgical hospitalization, or at any timepoint (before admission, during admission, and after admission)? (2) Are patients from distressed communities less likely to have advanced care planning documents in the EMR than patients from wealthier communities, after controlling for economic well-being as measured by the Distressed Communities Index? (3) What percentage of patients older than 65 years with hip fractures who died during their hospitalization for hip fracture surgery had advanced care planning documents uploaded in the EMR? METHODS: This was a retrospective, comparative study conducted at two geographically distinct hospitals: one urban Level I trauma center and one suburban Level II trauma center. Between 2017 and 2021, these two centers treated 850 patients for hip fractures. Among those patients, we included patients older than 65 years who were treated with open reduction and internal fixation, intramedullary nailing, hemiarthroplasty, or THA for a fragility fracture of the proximal femur. Based on that, 83% (709 of 850) of patients were eligible; a further 6% (52 of 850) were excluded because they had codes other than ICD-9 820 or ICD-10 S72.0, and another 2% (17 of 850) had incomplete datasets, leaving 75% (640 of 850) for analysis here. Most patients with incomplete datasets were in the prosperous Distressed Communities Index category. Among patients included in this study, the average age was 82 years, 70% (448 of 640) were women, and regarding the Distressed Communities Index, 32% (203 of 640) were in the prosperous category, 25% (159 of 640) were in the comfortable category, 15% (99 of 640) were in the mid-tier category, 5% (31 of 640) were in the at-risk category, and 23% (145 of 640) were in the distressed category. The primary outcome included the presence of advanced care planning documents (advanced directives, healthcare power of attorney, or physician orders for life-sustaining treatment) in the EMR before surgery, during the surgical admission, or at any time. The Distressed Communities Index was used to indicate economic well-being, and patients were identified as being in one of five Distressed Communities Index categories (prosperous, comfortable, mid-tier, at-risk, and distressed) based on ZIP Code. An exploratory analysis was conducted to determine variables associated with the presence of advanced care planning documents in the EMR. A multivariate regression was then performed for patients who did or did not have advanced care planning documents in their medical record at any time. The results are presented as ORs with the associated 95% confidence interval (CI). RESULTS: Nine percent (55 of 640) of patients had advanced care planning documents in the EMR preoperatively or during their surgical admission, and 22% (142 of 640) of patients had them in the EMR at any time. After controlling for potential confounding variables such as age, laterality (left or right hip), hospital type, and American Society of Anesthesiologists (ASA) classification, we found that patients in Distressed Communities Index categories other than prosperous had ORs lower than 0.7, with patients in the distressed category (OR 0.4 [95% CI 0.2 to 0.7]; p < 0.01) and comfortable category (OR 0.5 [95% CI 0.3 to 0.9]; p = 0.01) having a substantially lower odds of having advanced care planning documents in their EMR. Patients aged 86 to 95 years (OR 1.9 [95% CI 1.1 to 3.4]), those 96 years and older (OR 4.0 [95% CI 1.7 to 9.5]), and those with a higher ASA classification (OR 1.6 [95% CI 1.1 to 2.3]) had a higher odds of having advanced care planning documents in the EMR at any time. Among 14 patients who experienced in-hospital mortality, two had advanced care planning documents uploaded into their EMR, whereas 12 of 14 who died in the hospital did not have advanced care planning documents uploaded into their EMR. CONCLUSION: Orthopaedic surgeons should counsel patients regarding the risk for postoperative complications after fragility hip fracture surgery and engage in shared decision-making regarding advanced care planning documents with patients or, if the patients are unable, with their families. Additionally, implementing virtual education about advanced care planning documents and using easy-to-read forms may facilitate the completion of advanced care planning documents by patients older than 65 years, especially patients with low economic well-being. Limitations of this study include having a restricted number of patients in the at-risk and mid-tier Distressed Communities Index categories and a restricted number of patients identifying as non-White races/ethnicities. Future research should evaluate the effect of advanced care document presence in the EMR on end-of-life care intensity in patients treated for fragility hip fractures. LEVEL OF EVIDENCE: Level III, therapeutic study.

BACKGROUND: Stereotypes may discourage women from going into the historically male-dominated field of Adult Reconstruction. Other factors such as interest, confidence, and a sense of belonging may influence subspecialty choice. The objective of this study was to survey orthopedic surgery residents regarding their perceptions about Adult Reconstruction. METHODS: A validated survey evaluating social determinants of behavior was adapted to assess orthopedic surgery residents' perceptions of Adult Reconstruction. The survey was electronically distributed to residents from 16 United States and Canadian Accreditation Council for Graduate Medical Education-accredited residency programs. There were 93 respondents including 39 women (42%) and 54 men (58%). Study data were collected and managed using an electronic data capture tool. Descriptive statistics were reported for all continuous variables. Percentiles and sample sizes were reported for categorical variables. RESULTS: Women and men reported similar interest in Adult Reconstruction (46% versus 41%, P = .60). Fewer women reported that they were encouraged to go into Adult Reconstruction by faculty (62% versus 85%, P = .001). Women and men reported similar confidence in their own ability to succeed in the subspecialty of Adult Reconstruction. However, when asked about the ability of other residents, both sexes rated men as having higher levels of confidence. Women and men perceived other residents and faculty felt "men are better Adult Reconstruction surgeons," but did not personally agree with this statement. CONCLUSION: Women and men residents expressed similar rates of interest and self-confidence in Adult Reconstruction, but there were social barriers including negative stereotypes that may prevent them from pursuing careers in Adult Reconstruction.

OBJECTIVE: To develop evidence-based consensus recommendations for the optimal timing of hip and knee arthroplasty to improve patient-important outcomes including, but not limited to, pain, function, infection, hospitalization, and death at 1 year for patients with symptomatic and radiographic moderate-to-severe osteoarthritis or advanced symptomatic osteonecrosis with secondary arthritis of the hip or knee who have previously attempted nonoperative therapy, and for whom nonoperative therapy was ineffective, and who have chosen to undergo elective hip or knee arthroplasty (collectively referred to as TJA). METHODS: We developed 13 clinically relevant population, intervention, comparator, outcomes (PICO) questions. After a systematic literature review, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to rate the quality of evidence (high, moderate, low, or very low), and evidence tables were created. A Voting Panel, including 13 physicians and patients, discussed the PICO questions until consensus was achieved on the direction (for/against) and strength (strong/conditional) of the recommendations. RESULTS: The panel conditionally recommended against delaying TJA to pursue additional nonoperative treatment including physical therapy, nonsteroidal antiinflammatory drugs, ambulatory aids, and intraarticular injections. It conditionally recommended delaying TJA for nicotine reduction or cessation. The panel conditionally recommended delay for better glycemic control for patients who have diabetes mellitus, although no specific measure or level was identified. There was consensus that obesity by itself was not a reason for delay, but that weight loss should be strongly encouraged, and the increase in operative risk should be discussed. The panel conditionally recommended against delay in patients who have severe deformity or bone loss, or in patients who have a neuropathic joint. Evidence for all recommendations was graded as low or very low quality. CONCLUSION: This guideline provides evidence-based recommendations regarding the optimal timing of TJA in patients who have symptomatic and radiographic moderate-to-severe osteoarthritis or advanced symptomatic osteonecrosis with secondary arthritis for whom nonoperative therapy was ineffective to improve patient-important outcomes, including pain, function, infection, hospitalization, and death at 1 year. We acknowledge that the evidence is of low quality primarily due to indirectness and hope future research will allow for further refinement of the recommendations.

BACKGROUND: Occupational injuries are a prevalent and costly problem for orthopedic surgeons, especially arthroplasty surgeons performing physically demanding and repetitive tasks. The purpose of this study was to characterize occupational musculoskeletal injuries in female adult reconstruction surgeons. METHODS: A prospective survey about workplace musculoskeletal injuries was distributed to female attending adult reconstruction surgeons in May 2020. Participants were identified using subspecialty membership data, social media, and personal contacts. Results were analyzed using descriptive statistics. RESULTS: Of the total 63 female arthroplasty surgeons who responded, 65.1% were 30-45 year old, and 42.9% were within 5 years of practice, 68.3% sustained an occupational musculoskeletal injury, most commonly forearm/wrist/hand (79.1%), shoulder (48.8%), and low back (44.2%); 10.0% of reported occupational injuries not related to pregnancy resulted in the surgeon requiring time off work, while 48.2% required temporary modifications of job performance, and 10.9% required surgical treatment. Of the injured surgeons who reported having been pregnant, 65.4% reported a workplace exacerbation of a pregnancy-related musculoskeletal condition, including low back pain (52.9%), pubic symphysis pain (35.3%), and carpal tunnel syndrome (29.4%). CONCLUSION: A total of 68.3% of female arthroplasty surgeons reported occupational musculoskeletal injuries, predominately forearm/wrist/hand, with a portion of those requiring modifications of job performance. Musculoskeletal injuries may be mitigated by performing repetitive tasks ergonomically, correcting posture, using appropriately sized instrumentation, and using automated or lighter instruments, to potentially avoid modifications to job performance, time off work, or even surgical procedures. Further studies should investigate factors that contribute to injuries in arthroplasty surgeons and how they can be prevented.

Access and outcome disparities exist in hip and knee arthroplasty care. These disparities are associated with race, ethnicity, and social determinants of health such as income, housing, transportation, education, language, and health literacy. Additionally, medical comorbidities affecting postoperative outcomes are more prevalent in underresourced communities, which are more commonly communities of color. Navigating racial and ethnic differences in treating our patients undergoing hip and knee arthroplasty is necessary to reduce inequitable care. It is important to recognize our implicit biases and lessen their influence on our healthcare decision-making. Social determinants of health need to be addressed on a large scale as the current inequitable system disproportionally impacts communities of color. Patients with lower health literacy have a higher risk of postoperative complications and poor outcomes after hip and knee replacement. Low health literacy can be addressed by improving communication, reducing barriers to care, and supporting patients in their efforts to improve their own health. High-risk patients require more financial, physical, and mental resources to care for them, and hospitals, surgeons, and health insurance companies are often disincentivized to do so. By advocating for alternative payment models that adjust for the increased risk and take into account the increased perioperative work needed to care for these patients, surgeons can help reduce inequities in access to care. We have a responsibility to our patients to recognize and address social determinants of health, improve the diversity of our workforce, and advocate for improved access to care to decrease inequity and outcomes disparities in our field.

BACKGROUND: The American Association of Hip and Knee Surgeons (AAHKS) has one of the lowest percentages of women members among orthopedic surgery subspecialty societies, having increased from 1.3% to 3.1% since 2012. Our purpose was to report the representation of women in various speaking roles at the AAHKS annual meeting over this time period. METHODS: We accessed the 2012-2019 AAHKS annual meeting programs online and reviewed all paper presenters, symposium faculty, and session moderators. We recorded instances of women speakers and their degree and specialty. We calculated the percentage of women speakers, women orthopedic surgeon speakers, women session moderators, and women symposium faculty for the overall period of 2012-2019, and for each annual meeting. RESULTS: Between 2012 and 2019, 33/877 (3.8%) of all speakers at AAHKS were women. Of these, 21 were women orthopedic surgeons, or 2.4% of all speakers. The proportion of total women speakers per year ranged from 1.7% (2017) to 6.4% (2013). Twenty-four of 492 (4.9%) paper presenters were women, and 12/492(2.4%) were women orthopedic surgeons. Four of 143 (2.8%) session moderators were women, and all were orthopedic surgeons. Five of 245 (2.0%) symposium faculty were women, and 0/245 (0%) were women orthopedic surgeons. CONCLUSION: Although the percentage of women AAHKS members has grown since 2012, the small percentage of women orthopedic surgeons speaking at AAHKS has not. There were no women orthopedic surgeons included on symposium faculty over this entire period. We appreciate and encourage efforts to improve gender diversity among speakers at AAHKS annual meetings.

INTRODUCTION: The relationship between surgeon volume and risk of dislocation after total hip arthroplasty (THA) is debated. This study sought to characterize this association and assess patient outcomes using a nationwide patient and surgeon registry. METHODS: The Premier Healthcare Database was queried for adult primary elective THA patients from January 1, 2016, to December 31, 2019. Annual surgeon volume and 90-day risk of dislocation were modeled using multivariable logistic regression with restricted cubic splines. Bootstrap analysis identified a threshold annual case volume, corresponding to the maximum decrease in dislocation risk. Surgeons with an annual volume greater than the threshold were deemed high volume, and those with an annual volume less than the threshold were low volume. Each surgeon within a given year was treated as a unique entity (surgeon-year unit). 90-day complications of patients treated by high-volume and low-volume surgeons were compared. RESULTS: From 2016 to 2019, 352,131 THAs were performed by 5,106 surgeons. The restricted cubic spline model demonstrated an inverse relationship between risk of dislocation and surgeon volume (threshold: 109 cases per year). A total of 9,967 (87.8%) low-volume surgeon-year units had individual dislocation rates lower than the average of the entire surgeon cohort. Patients treated by high-volume surgeons had decreased risk of dislocation (adjusted odds ratio [aOR], 0.60; 95% CI, 0.54 to 0.67), periprosthetic fracture (aOR, 0.87; 95% CI, 0.76 to 0.99), periprosthetic joint infection (aOR, 0.63; 95% CI, 0.56 to 0.69), readmission (aOR, 0.70; 95% CI, 0.67 to 0.73), and in-hospital death (aOR, 0.60; 95% CI, 0.46 to 0.80). CONCLUSION: While most of the low-volume surgeons had dislocation rates lower than the cohort average, increasing annual surgeon case volume was associated with a reduction in risk of dislocation after primary elective THA. THERAPEUTIC LEVEL OF EVIDENCE: Level IV.
RESUMEN
Background: As demand for total hip arthroplasty and total knee arthroplasty increases, more surgeons have pursued subspecialty training in adult reconstruction. However, little information is available regarding the practice environment in which these fellowship-trained surgeons practice. The purpose of this study was to describe the practice environments of contemporary adult reconstruction surgeons. Methods: A survey was developed and distributed to members of the American Association of Hip and Knee Surgeons from December 2022 to January 2023. Information was collected on surgeon demographics, practice setting, call requirements, and educational debt. Responses were recorded using frequencies and proportions. Results: A total of 886 of 2471 (36%) surgeons completed the survey, with 93% identifying as male and 81% as white. The primary surgical practice locations were: community hospital 53%, academic/tertiary hospital 24%, specialty orthopedic hospital 17%, and ambulatory surgery center 7%. Nearly half (49%) of the respondents practiced in orthopedic specialty groups, and 60% spent 50%-66% of their clinical time in the office. The majority of surgeons performed between 101-250 (20%) and 251-400 (31%) arthroplasty cases per year, though this varied considerably. Call was taken by 77% of surgeons, yet only 54% received compensation. Conclusions: The most common practice setting for adult reconstruction surgeons was in a community-based hospital as part of a large orthopedic specialty group. Despite the considerable variability in annual procedure volume, the majority of surgeons spent over half their clinical time in office and had call obligations with variable compensation models.
RESUMEN
Background: In 2020, the coronavirus disease 2019 (COVID-19) pandemic caused the cessation of nonemergent total joint arthroplasty (TJA, referring to total hip and total knee arthroplasty) operations between mid-March and April 2020. The purpose of this study is to analyze the effects and potential disparities in access to care due to the COVID-19 restrictions. Methods: A database was used to examine the demographics of patients undergoing TJA from May to December 2019 (pre-COVID-19) and from May to December 2020 (post-COVID-19 restrictions). Categorical covariates were summarized by reporting counts and percentages and compared using Fisher exact tests. Continuous covariates were summarized by reporting means and standard deviations. Two-sample t-tests were used for continuous covariates. The equality of TJA counts by year was tested using a test of proportions. Results: There were more TJA procedures performed during the post-COVID-19 period in 2020 than in the pre-COVID-19 period (1151 vs 882, P < .001). There was an increase in the relative percentage of THAs vs TKAs performed in 2020 vs 2019 (26.9% vs 18.8%, P < .001) and an increase in patients with Medicaid with a decrease in private insurance (P = .043). The average length of stay was shorter in 2020 with a greater percentage of TJAs performed outpatient (P < .001). There were no differences in patient sex, race, body mass index, smoking status, or age between the 2 periods. Conclusions: A relative increase in THA procedures, an increase in patients with Medicaid and decrease in private insurance, and a a decreased length of stay were seen after COVID-19 restrictions. These trends may reflect pandemic-related changes in insurance status as well as the growing shift to same-day discharge.
RESUMEN
Background: The extent to which hemoglobinopathies other than sickle anemia (HbSS) are associated with hip osteonecrosis is unknown. Sickle cell trait (HbS), hemoglobin SC (HbSC), and sickle/ß-thalassemia (HbSßTh) may also predispose to osteonecrosis of the femoral head (ONFH). We sought to compare the distributions of indications for a total hip arthroplasty (THA) in patients with and without specific hemoglobinopathies. Methods: PearlDiver, an administrative claims database, was used to identify 384,401 patients aged 18 years or older undergoing a THA not for fracture from 2010 to 2020, with patients grouped by diagnosis code (HbSS N = 210, HbSC N = 196, HbSßTh N = 129, HbS N = 356). ß-Thalassemia minor (N = 142) acted as a negative control, and patients without hemoglobinopathy as a comparison group (N = 383,368). The proportion of patients with ONFH was compared to patients without it by hemoglobinopathy groups using chi-squared tests before and after matching on age, sex, Elixhauser Comorbidity Index, and tobacco use. Results: The proportion of patients with ONFH as the indication for THA was higher among those with HbSS (59%, P < .001), HbSC (80%, P < .001), HbSßTh (77%, P < .001), and HbS (19%, P < .001) but not with ß-thalassemia minor (9%, P = .6) than the proportion of patients without hemoglobinopathy (8%). After matching, the proportion of patients with ONFH remained higher among those with HbSS (59% vs 21%, P < .001), HbSC (80% vs 34%, P < .001), HbSßTh (77% vs 26%, P < .001), and HbS (19% vs 12%, P < .001). Conclusions: Hemoglobinopathies beyond sickle cell anemia were strongly associated with having osteonecrosis as the indication for THA. Further research is needed to confirm whether this modifies THA outcomes.
RESUMEN
BACKGROUND: Medicaid insurance coverage among patients undergoing total hip arthroplasty (THA) or those undergoing total knee arthroplasty (TKA) has been associated with worse postoperative outcomes compared with patients without Medicaid. Surgeons and hospitals with lower annual total joint arthroplasty (TJA) volume have also been associated with worse outcomes. This study sought to characterize the associations between Medicaid insurance status, surgeon case volume, and hospital case volume and to assess the rates of postoperative complications compared with other payer types. METHODS: The Premier Healthcare Database was queried for all adult patients who underwent primary TJA from 2016 to 2019. Patients were divided on the basis of their insurance status: Medicaid compared with non-Medicaid. The distribution of annual hospital and surgeon case volume was assessed for each cohort. Multivariable analyses were performed accounting for patient demographic characteristics, comorbidities, surgeon volume, and hospital volume to assess the 90-day risk of postoperative complications by insurance status. RESULTS: Overall, 986,230 patients who underwent TJA were identified. Of these, 44,370 (4.5%) had Medicaid. Of the patients undergoing TJA, 46.4% of those with Medicaid were treated by surgeons performing ≤100 TJA cases annually compared with 34.3% of those without Medicaid. Furthermore, a higher percentage of patients with Medicaid underwent TJA at lower-volume hospitals performing ≤500 cases annually, 50.8% compared with 35.5% for patients without Medicaid. After accounting for differences among the 2 cohorts, patients with Medicaid remained at increased risk for postoperative deep vein thrombosis (adjusted odds ratio [OR], 1.16; p = 0.031), pulmonary embolism (adjusted OR, 1.39; p < 0.001), periprosthetic joint infection (adjusted OR, 1.35; p < 0.001), and 90-day readmission (adjusted OR, 1.25; p < 0.001). CONCLUSIONS: Patients with Medicaid were more likely to undergo TJA performed by lower-volume surgeons at lower-volume hospitals and had higher rates of postoperative complications compared with patients without Medicaid. Future research should assess socioeconomic status, insurance, and postoperative outcomes in this vulnerable patient population seeking arthroplasty care. LEVEL OF EVIDENCE: Prognostic Level III .
