RESUMO
INTRODUCTION: Preoperative anemia is an independent risk factor of complications after primary total hip arthroplasty (THA). Currently used hemoglobin thresholds are not developed for risk stratification of arthroplasty patients and do not provide surgery-specific information on postoperative complication risk. Thus, we aimed to calculate THA-specific preoperative hemoglobin strata that observe the likelihood of 90-day blood transfusion and determine whether these strata are associated with increased risk of 90-day complications and 2-year prosthetic joint infection (PJI). METHODS: A retrospective cohort analysis identified 56,101 patients who underwent primary THA from 2013 to 2022. Using the lowest hemoglobin value for each patient one month before THA, stratum-specific likelihood ratio (SSLR) analysis calculated sex-based hemoglobin strata associated with the likelihood of 90-day postoperative blood transfusion. Propensity score matching was performed. Incidence rates and risk of 90-day major complications and 2-year PJI were observed for each identified preoperative hemoglobin stratum. RESULTS: SSLR analysis identified five male (strata, likelihood ratio [<10.4 g/dL, 12.5; 10.5 to 11.4 g/dL, 8.0; 11.5 to 12.4 g/dL, 2.4; 12.5 to 13.4 g/dL, 1.3; 13.5 to 13.9 g/dL, 0.5]) and five female (<8.9 g/dL, 10.7; 9.0 to 10.9 g/dL, 4.0; 11.0 to 11.4 g/dL, 2.0; 12.0 to 12.9 g/dL, 1.0; 13.0 to 13.4 g/dL, 0.6) preoperative hemoglobin strata associated with varying likelihoods of 90-day blood transfusion after THA. After matching in both male and female cohorts, as the calculated preoperative hemoglobin strata decreased, the relative risk of overall 90-day major complications and 2-year PJI increased incrementally (all P < 0.05). CONCLUSION: SSLR analysis established THA-specific sex-based preoperative hemoglobin strata that observe the likelihood of 90-day blood transfusion and predict the risk of 90-day medical complications and 2-year PJI. These strata are a first of their kind in THA research. While preoperatively optimizing patients, we recommend using these hemoglobin thresholds to help guide decisions on presurgery anemia optimization and to reduce the need for postoperative blood transfusion. LEVEL OF EVIDENCE: Level III.
RESUMO
OBJECTIVES: To compare 1-year revision rates among left-sided and right-sided intertrochanteric femur fractures. DESIGN: Retrospective. SETTING: 120+ contributing centers to multicentered database. PATIENT SELECTION CRITERIA: Patients who sustained intertrochanteric femur fracture (ITFF) and had a cephalomedullary nail (CMN) from 2015 to 2022 were identified. Patients were then stratified based on left-sided or right-sided fracture. Patients were excluded if younger than 18 years with <1-year follow-up. The intervention investigated was CMN on left or right side. OUTCOME MEASURES AND COMPARISONS: One-year revision surgery, comparing CMN performed on left or right side for ITFFs. RESULTS: In total, 113,626 patients met inclusion criteria, with 55,295 in the right-sided cohort and 58,331 in the left-sided cohort. There was no difference between cohorts with respect to age, gender, diabetes, osteoporosis, chronic kidney disease, or congestive heart failure (P > 0.05 for all). Patients who sustained a left ITFF and treated with a CMN were more likely to have revision surgery at 1 year (Left: 1.24%, Right: 0.90%; OR: 1.24; 95% confidence interval [CI], 1.15-1.1.33) or develop a nonunion or malunion (Left: 1.30%, Right: 0.98%; OR: 1.31; 95% CI, 1.14-1.52). The most common revision surgery conducted for both cohorts was conversion total hip arthroplasty (Left: 70.4% and Right: 70.0%). CONCLUSIONS: Patients who sustained a left intertrochanteric femur fracture and were treated with a CMN were more likely to undergo revision at 1 year due to nonunion. There were no differences in demographics and comorbidities between cohorts. Though left-sided versus right-sided confounding variables may exist, the difference in nonunion rate may be explained by clockwise torque of the lag screw used in most implants. Increased awareness, implant design, and improved technique during fracture reduction and fixation may help lower this disproportionate nonunion rate and its associated morbidity and financial impact. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Background Cold weather in the first few months of life may increase the risk of a late diagnosis of developmental dysplasia of the hip (DDH). Early detection of DDH can often be treated non-surgically. The purpose of this study is to observe whether the rates of surgical intervention for DDH differ based on average outdoor temperatures in the winter months. Methods A retrospective observational study of DDH patients diagnosed from 2010 to 2021 was conducted using a national administrative database. Five geographic regions were defined based on the average temperatures in the coldest quarter of the year. The rates of DDH-related surgeries were compared across these temperature regions. Results A total of 55,911 patients ≤5 years old with a DDH diagnosis from 2010 to 2021 were identified in the database. When compared to the warmest region (Group 5), the coldest region (Group 1) had higher rates of open reduction (4.59% vs. 2.06%, p<0.001), adductor tenotomy (6.95% vs. 2.91%, p<0.001), femoral osteotomy (5.75% vs. 2.04%, p<0.001), pelvic osteotomy (5.27% vs. 2.04%, p<0.001), and total DDH surgeries (11.42% vs. 5.03%, p<0.001). Conclusion Children living in states with an average winter temperature of -6.17°C had an increased likelihood of requiring surgical intervention for DDH within the first five years of life.
RESUMO
BACKGROUND: Modern cementless total knee arthroplasty (TKA) fixation has shown comparable long-term outcomes to cemented TKA, but the trend of using cementless TKA remains unclear. This study aimed to investigate the trend of using cementless TKA based on a national database. METHODS: The patients undergoing cementless TKA between 2015 and 2021 were retrospectively extracted from the PearlDiver (Mariner dataset) Database. The annual percentage of cementless TKA was calculated using the following formula: annual number of cementless TKA/annual number of TKA. The trend of the number of patients undergoing cementless TKA was created according to a compounded annual growth rate (CAGR) calculation of annual percentages. Patient age, comorbidity, region, insurance type, etc., were also investigated. Differences were considered statistically significant at P < 0.05. RESULTS: Of the 574,848 patients who received TKA, 546,731 (95%) underwent cemented fixation and 28,117 (5%) underwent cementless fixation. From 2015 to 2021, the use of cementless TKA significantly increased by 242% from 3 to 9% (compounded annual growth rate (CAGR): + 20%; P < 0.05). From 2015 to 2021, we observed a CAGR greater than 15% for all age groups (< 50, 50-59, 60-69, 70-74, 75 +), insurance types (cash, commercial, government, Medicare, Medicaid), regions (Midwest, Northeast, South, West), sex (male and female), and certain comorbidities (osteoporosis, diabetes mellitus, tobacco use, underweight (BMI < 18.5), rheumatoid arthritis) (P < 0.05 for all). Patients undergoing TKA with chronic kidney disease, prior fragility fractures, and dementia demonstrated a CAGR of + 9%-13% from 2015 to 2021 (P < 0.05). CONCLUSION: From 2015 to 2021, the use of cementless TKA saw a dramatic increase in all patient populations. However, there is still no consensus on when to cement and in whom. Clinical practice guidelines are needed to ensure safe and effective use of cementless fixation.
RESUMO
BACKGROUND: Bariatric surgery (BS) is indicated for select class III obesity patients undergoing total knee arthroplasty (TKA) to reduce obesity-related complications. This study assessed the effect of BS on TKA revision rates compared to the general population and class III obesity patients without a history of BS. METHODS: A national database identified patients who had primary TKA. They were divided into two groups: those with BS prior to TKA and those without. Patients without BS formed two control groups, a matched general population, and a matched class III obese cohort. The BS group was matched with controls based on age, Charlson Comorbidity Index (CCI), gender, and diabetes mellitus. Revision rates were analyzed using Kaplan-Meier survival analysis and hazard ratios (HR), calculated using Cox proportional hazard modeling. RESULTS: 14,292 BS patients were compared to 57,006 matched general population controls, and 19,504 BS patients were compared to 77,846 matched class III obesity control patients. BS patients had a higher risk of 5-year all-cause revision (HR: 1.13; P = 0.014) and revision due to periprosthetic fracture (HR: 1.39; P < 0.001) compared to the general population. Compared to class III obesity controls, BS patients had a lower risk of 5-year revision due to prosthetic joint infection (HR: 0.77; P = 0.001), with no difference in all-cause revision (P = 0.362). CONCLUSION: BS does not reduce all-cause TKA revision risk compared to the general or matched class III obesity population. However, it lowers the risk of revision due to prosthetic joint infection when compared to patients with class III obesity. LEVEL OF EVIDENCE: IV.

BACKGROUND: Total knee arthroplasty (TKA) for solid organ transplant (SOT) patients is becoming more prominent as life expectancy in this population increases. However, data on long-term (10 year) implant survivorship in this cohort are sparse. The purpose of this study was to compare 90-day, 2-year, 5-year, and 10-year implant survivability following primary TKA in patients who did and did not have prior SOT. METHODS: The PearlDiver database was utilized to query patients who underwent unilateral elective TKA with at least 2 years of active follow-up. These patients were stratified into those who had a SOT before TKA and those who did not. The SOT cohort was propensity-matched to control patients based on age, sex, Charlson Comorbidity Index, and obesity in a 1:2 ratio. Cumulative incidence rates and hazard ratios (HRs) were compared between the SOT, matched, and unmatched cohorts. RESULTS: No difference was observed in 10-year cumulative incidence and risk of all-cause revision surgery in TKA patients with prior SOT when compared to matched and unmatched controls. Compared to the matched control, the SOT cohort had no difference in the risk of revision when stratified by indication and timing. However, when compared to the unmatched control, patients who had prior SOT had a higher risk for revision due to periprosthetic joint infection at 10 years (HR: 1.80; 95% confidence interval: 1.17 to 2.76) as well as all-cause revision within 90 days after TKA (HR: 1.93; 95% confidence interval: 1.10 to 3.36). CONCLUSIONS: Prior SOT patients have higher rates of all-cause revision within 90 days and periprosthetic joint infection within 10 years when compared to the general population, likely associated with the elevated number of comorbidities in SOT patients and not the transplant itself. Therefore, these patients should be monitored in the preoperative and early postoperative settings to optimize their known comorbidities.

BACKGROUND: In patients considered high-risk for infection, extended oral antibiotic (EOA) prophylaxis has been demonstrated to reduce rates of prosthetic joint infection following total hip arthroplasty (THA). Although national guidelines regarding their use have not yet been created, the increase in literature surrounding EOA prophylaxis suggests a potential change in practice patterns. The purpose of this study was to investigate the trends in utilization of EOA prophylaxis following THA from 2010 to 2022 and identify prescription patterns. METHODS: A total of 646,059 primary THA and 51,879 aseptic revision THA patients were included in this study. Patients who underwent primary or aseptic revision THA between 2010 and 2022 were identified in a national administrative claims database. Rates and duration of EOA prescriptions were calculated. A secondary analysis examined rates of utilization across demographics, including patients considered high risk for infection. RESULTS: From 2010 to 2022, utilization of EOA increased by 366% and 298% following primary and revision THA, respectively. Of patients prescribed postoperative antibiotics, 30% and 59% were prescribed antibiotics for more than 7 days following primary and revision THA, respectively. Rates of utilization were similar between high-risk individuals and the general population. CONCLUSIONS: Rates of utilization of EOA prophylaxis after THA have increased significantly since 2010. As current trends demonstrate a wide variation in prescription patterns, including in length of antibiotic duration and in patient population prescribed, guidelines surrounding the use of EOA prophylaxis after THA are necessary to promote antibiotic stewardship while preventing rates of periprosthetic joint infection.

Orthopaedic surgery lags in recruiting women and under-represented minorities (URMs). In addition, women and URMs hold fewer leadership roles across orthopaedic subspecialties. This inequity is geographically heterogeneous, with female URM residents and attendings being more concentrated in some areas of the country. For instance, practicing female orthopaedic surgeons are more prevalent in Northeast and Pacific programs. Mentorship and representation in leadership positions play a notable role in trainee recruitment. Video communication platforms offer a novel mechanism to reach historically under-represented students across the country. We reviewed five established mentorship programs focused on women and URMs. Each program emphasized a longitudinal relationship between mentors and mentees. In reviewing these programs, we sought to identify the successful components of each program. Leveraging and integrating effective components already established by conventional mentorship programs into virtual programming will aid in optimizing those programs and improve geographic equity in access to mentorship resources. It is critical to extend the principles of successful mentorship programs to technology-enabled programs moving forward.

INTRODUCTION: Spinal anesthesia (SA) allows total joint arthroplasty to be done while minimizing opioids and systemic anesthetic agents compared with general anesthesia (GA). SA has been associated with shortened postoperative recovery; however, the relationship between SA, major postoperative complications, and pneumonia (PNA) remains unclear. METHODS: Patients in a large, national database who underwent total hip arthroplasty or total knee arthroplasty from 2010 to 2020 were identified. 1:1 propensity score matching was used to create matched groups of patients who underwent SA and GA. The groups were matched by age, sex, chronic obstructive pulmonary disease, smoking status, Charlson Comorbidity Index, and American Society of Anesthesiology (ASA) classification. 1:1 matching was also done among the ASA classifications as a subanalysis. RESULTS: Overall, equally matched groups of 217,267 patients who underwent SA versus GA were identified. 850 patients (0.39%) developed postoperative PNA after GA versus 544 patients (0.25%) after SA ( P < 0.001). The risk of major complications was 6,922 (3.2%) in the GA group and 5,401 (2.5%) in the SA group ( P < 0.001). Similarly, the risk of unplanned postoperative reintubation was higher (0.18% versus 0.10%, P < 0.001) and mortality was higher (0.14% versus 0.09%, P < 0.001) in the GA group than in the SA group. In ASA 1 to 3 patients, the risk of PNA was 0.08% to 0.21% higher with GA than with SA. In ASA 4 patients, the risk of PNA was 0.42% higher in SA than in GA (1.92% versus 1.5%, P < 0.001) and the mortality rate was nearly doubled in GA than in SA (1.46% versus 0.77%, P = 0.017). DISCUSSION: Overall, GA was associated with a small but markedly higher rate of major complications, mortality, and PNA than SA in patients undergoing total joint arthroplasty when matching for differences in comorbidities. ASA 4 patients experienced the greatest increase in absolute risk of mortality with GA versus SA.

Background Distal radius fractures (DRFs) are the most common fracture of the upper extremity. Given that steroids are one of the most commonly prescribed drugs and are usually prescribed for chronic conditions, steroid use represents a key factor to consider in how to optimize perioperative outcomes. Questions/Purposes The purpose of this study was to investigate if there are differences in perioperative outcomes for patients undergoing DRF open reduction and internal fixation based on preoperative steroid use. Patients and Methods Adult patients who underwent operative treatment for DRF from 2007 to 2018 were identified in a national database. Patients were divided into two cohorts as follows: (1) no steroid usage and (2) preoperative steroid usage. In this analysis, various postoperative complications, as well as extended length of stay and reoperation, were assessed. Bivariate analyses and multivariable logistical regression were performed. Results Among a total of 16,505 patients undergoing operative treatment for DRF, 16,145 patients (97.8%) did not have steroid usage and 360 (2.2%) had steroid usage. Following adjustment, an increased risk of extended length of hospital stay greater than 3 days (odds ratio [OR] = 1.646; p = 0.012) was seen in the steroid usage group compared with those who did not use steroids within 30 days of surgery. Conclusion Preoperative steroid use is associated with increased length of stay over 3 days after DRF open reduction and internal fixation surgery but is not associated with any of the other complications that were assessed in this study. Level of Evidence This is a Level III, retrospective study.
RESUMO
BACKGROUND: Osteoporosis is a known, modifiable risk factor for lower extremity periprosthetic fractures. Unfortunately, a high percentage of patients at risk of osteoporosis who undergo THA or TKA do not receive routine screening and treatment for osteoporosis, but there is insufficient information determining the proportion of patients undergoing THA and TKA who should be screened and their implant-related complications. QUESTIONS/PURPOSES: (1) What proportion of patients in a large database who underwent THA or TKA met the criteria for osteoporosis screening? (2) What proportion of these patients received a dual-energy x-ray absorptiometry (DEXA) study before arthroplasty? (3) What was the 5-year cumulative incidence of fragility fracture or periprosthetic fracture after arthroplasty of those at high risk compared with those at low risk of osteoporosis? METHODS: Between January 2010 and October 2021, 710,097 and 1,353,218 patients who underwent THA and TKA, respectively, were captured in the Mariner dataset of the PearlDiver database. We used this dataset because it longitudinally tracks patients across a variety of insurance providers throughout the United States to provide generalizable data. Patients at least 50 years old with at least 2 years of follow-up were included, and patients with a diagnosis of malignancy and fracture-indicated total joint arthroplasty were excluded. Based on this initial criterion, 60% (425,005) of THAs and 66% (897,664) of TKAs were eligible. A further 11% (44,739) of THAs and 11% (102,463) of TKAs were excluded because of a prior diagnosis of or treatment for osteoporosis, leaving 54% (380,266) of THAs and 59% (795,201) of TKAs for analysis. Patients at high risk of osteoporosis were filtered using demographic and comorbidity information provided by the database and defined by national guidelines. The proportion of patients at high risk of osteoporosis who underwent osteoporosis screening via DEXA scan within 3 years was observed, and the 5-year cumulative incidence of periprosthetic fractures and fragility fracture was compared between the high-risk and low-risk cohorts. RESULTS: In total, 53% (201,450) and 55% (439,982) of patients who underwent THA and TKA, respectively, were considered at high risk of osteoporosis. Of these patients, 12% (24,898 of 201,450) and 13% (57,022 of 439,982) of patients who underwent THA and TKA, respectively, received a preoperative DEXA scan. Within 5 years, patients at high risk of osteoporosis undergoing THA and TKA had a higher cumulative incidence of fragility fractures (THA: HR 2.1 [95% CI 1.9 to 2.2]; TKA: HR 1.8 [95% CI 1.7 to 1.9]) and periprosthetic fractures (THA: HR 1.7 [95% CI 1.5 to 1.8]; TKA: HR 1.6 [95% CI 1.4 to 1.7]) than those at low risk (p < 0.001 for all). CONCLUSION: We attribute the higher rates of fragility and periprosthetic fractures in those at high risk compared with those at low risk to an occult diagnosis of osteoporosis. Hip and knee arthroplasty surgeons can help reduce the incidence and burden of these osteoporosis-related complications by initiating screening and subsequently referring patients to bone health specialists for treatment. Future studies might investigate the proportion of osteoporosis in patients at high risk of having the condition, develop and evaluate practical bone health screening and treatment algorithms for hip and knee arthroplasty surgeons, and observe the cost-effectiveness of implementing these algorithms. LEVEL OF EVIDENCE: Level III, therapeutic study.

The study found that patients undergoing total knee arthroplasty with prior fragility fracture had increased risk of subsequent fragility fracture and periprosthetic fracture within 8 years postoperatively when compared to those without a prior history. However, these patients were not at increased risk for all-cause revision within this period. PURPOSE: The aim of this study was to characterize the association of prior FFs on long-term risk of secondary fragility fracture (FF), periprosthetic fracture (PPF), and revision TKA. METHODS: Patients at least 50 years of age who underwent elective TKA were identified in the PearlDiver Database. Patients were stratified based on whether they sustained a FF within 3 years prior to TKA (7410 patients) or not (712,954 patients). Demographics and comorbidities were collected. Kaplan Meier analysis was used to observe the cumulative incidence of all-cause revision, PPF, and secondary FF within 8 years of TKA. Cox Proportional hazard ratio analysis was used to statistically compare the risk. RESULTS: In total, 1.0% of patients had a FF within three years of TKA. Of these patients, only 22.6% and 10.9% had a coded diagnosis of osteoporosis and osteopenia, respectively, at time of TKA. The 8-year cumulative incidence of secondary FF and periprosthetic fracture was significantly higher in those with a prior FF (27.5% secondary FF and 1.9% PPF) when compared to those without (9.1% secondary FF and 0.7% PPF). After adjusting for covariates, patients with a recent FF had significantly higher risks of secondary FF (HR 2.73; p < 0.001) and periprosthetic fracture (HR 1.86; p < 0.001) than those without a recent FF. CONCLUSIONS: Recent FF before TKA is associated with increased risk for additional FF and PPF within 8 years following TKA. Surgeons should ensure appropriate management of fragility fracture is undertaken prior to TKA to minimize fracture risk, and if not, be vigilant to identify patients with prior FF or other bone health risk factors who may have undocumented osteoporosis.

Background: While database studies have become more prevalent in the literature, there is concern over their value. In addition, the questions they are suitable to answer are limited. Questions/Purposes: We sought to determine the incidence of database studies in the orthopedic literature and in each subspecialty. In addition, we wanted to assess the impact of database studies on the literature by determining whether citations and Altmetric Attention Scores (AAS) varied by study type (studies using internal or external databases and those not using databases). Methods: We searched PubMed for articles published in impactful orthopedic surgery journals in the year 2018. All articles were discoverable on the Altmetric explorer portal database. Impact was determined by journal impact factor. Study design, subspecialty, number of citations, and AAS were obtained. Univariable analyses were conducted between study type, demographic variables, and the outcome of either citation count or AAS. Multivariable analyses were performed to identify independent predictors of the primary outcomes. Subgroup analyses were performed to differentiate the impact of external and internal database studies compared with non-database studies. Results: A total of 2684 total articles were eligible for inclusion. Of these, 366 studies (13.6%) were database studies. Hip and knee articles had the greatest incidence of database studies. Database studies had significantly more citations (5.9 vs 4.0) and significantly higher AAS (12.8 vs 11.3) compared with non-database studies. External database studies had significantly more citations (6.7 vs 4.8) and significantly higher AAS (14.0 vs 10.7) than internal database studies. Internal database studies had higher traditional citation counts but similar AAS to non-database studies. Conclusions: In 2018, database studies in well-reputed orthopedic journals had a greater number of citations but similar AAS compared with non-database studies. Further studies are warranted.
RESUMO
BACKGROUND: Literature regarding total knee arthroplasty (TKA) outcomes in sickle cell disease (SCD) is limited. Moreover, 10-year survivorship of SCD implants is unknown. This study aimed to observe 10-year cumulative incidence and indications for revision TKA in patients who did and did not have SCD. METHODS: Patients who underwent primary TKA were identified using a large national database. The SCD patients were matched by age, sex, and a comorbidity index to a control cohort in a 1:4 ratio. The 10-year cumulative incidence rates were determined using Kaplan-Meier survival analyses. Multivariable analyses were conducted using Cox proportional hazard modeling. Chi-squared analyses were conducted to compare indications for revision between cohorts. In total, 1,010 SCD patients were identified, 100,000 patients included in the unmatched control, and 4,020 patients included in the matched control. RESULTS: Compared to the unmatched control cohort, SCD patients exhibited higher 10-year all-cause revision (HR: 1.86; P < .001) with higher proportions of revisions for periprosthetic joint infection (PJI) (P < .001), aseptic loosening (P < .001), and hematoma (P < .001). Compared to the matched control, SCD patients had higher 10-year all-cause revision (Hazard Ratio (HR): 1.39; P = .034) with a higher proportion of revisions for PJI (P = .044), aseptic loosening (P = .003), and hematoma (P = .019). CONCLUSION: Independent of other comorbidities, SCD patients are more likely to undergo revisions for PJI, aseptic loosening, and hematoma compared to patients who do not have SCD. Due to the high-risk of these complications, perioperative and postoperative surgical optimization should be enforced in SCD patients.

Purpose: The purpose of this study was to determine whether extremities undergoing carpal tunnel release (CTR) have an increased rate of trigger finger (TF) compared with conservatively managed carpal tunnel syndrome. Methods: Data were collected from the Humana Insurance Database, and subjects were chosen on the basis of a history of CTR with propensity matching performed to develop a nonsurgical cohort. Following propensity matching, 16,768 patients were identified and equally split between surgical and nonsurgical treatments. Demographic information and medical comorbidities were recorded. Univariate and multivariate analyses were performed to identify risk factors for the development of TF within 6 months of carpal tunnel syndrome diagnosis. Results: Patients in the surgical cohort were more likely to develop TF than those in the nonsurgical cohort whether in the ipsilateral or contralateral extremity. Whether managed surgically or nonsurgically, extremities with carpal tunnel syndrome demonstrated an increased prevalence of TF than their contralateral, unaffected extremity. Conclusions: Surgeons should be aware of the association of TF and CTR both during the presurgical and postsurgical evaluations as they might impact patient management. With knowledge of these data, surgeons may be more attuned to detecting an early TF during the postsurgical period and offer more aggressive treatment of TF pathology during CTR.

RESUMO
BACKGROUND: Colonoscopy is routinely performed for colorectal cancer screening in patients who have a preexisting unicompartmental knee arthroplasty (UKA), total knee arthroplasty (TKA), or total hip arthroplasty (THA) prostheses. However, colonoscopy is theorized to provoke transient bacteremia, providing a potential nidus for periprosthetic joint infection. This study aimed to investigate the risk of aseptic and septic revision surgery in patients who underwent diagnostic colonoscopy or invasive colonoscopy within one year following UKA, TKA, or THA. METHODS: A retrospective cohort analysis was performed using a national database. Patients were identified using Current Procedural Terminology. In total, 52,891 patients underwent UKA, 1,049,218 underwent TKA, and 526,296 underwent THA. Data were analyzed with univariate analysis preceding multivariable logistic regressions to investigate outcomes of interest at 2 and 3 years from the index procedure. RESULTS: Diagnostic colonoscopy resulted in no increase in odds of all-cause or septic revision surgery for any prostheses. At both time points, invasive colonoscopy resulted in lower odds of all-cause revision (P < .05) for patients with UKA, decreased odds of septic revision (P < .001) for patients with TKA, and decreased odds of both all-cause and septic revision (P < .05) for patients with THA. CONCLUSION: Our results show that diagnostic colonoscopy was not a significant risk factor for revision following UKA, TKA, or THA. Paradoxically, invasive colonoscopy was protective against revision, even with very minimal use of antibiotic prophylaxis observed. This study addresses the theory that colonoscopy procedures may threaten an existing joint prosthesis via transient bacteremia and shows no increase in revision outcomes following colonoscopy. LEVEL OF EVIDENCE: Level III.

BACKGROUND: Elevated body mass index (BMI) is a risk factor for complications following total knee arthroplasty (TKA). Thus, we believe it is important to constantly re-evaluate the relationship between BMI and complication risk following TKA. METHOD: Patients undergoing primary TKA were identified in a national database from 2012-2020. Rates of major complications, minor complications, and length of stay (LOS) greater than 2 days were calculated. The prevalence of postoperative outcomes were calculated per unit of BMI and then multiplied by a factor of 10^2 or 10^3 in order to create adjusted-BMI (aBMI). To isolate the effect of aBMI on postoperative outcomes, changes over time were analyzed using linear regression analysis controlling for age, sex, American Society of Anesthesiology (ASA) classification and smoking status. RESULTS: 365,333 patients were included. Mean BMI 33 ± 6.8. 10,616 (2.9%) of patients had a major postoperative complication, 9,345 (2.6%) minor complications, 3,277 (0.9%) had a deep or superficial surgical site infection (SSI). 133,563 (37%) of patients had LOS > 2 days. From 2012-2020, the ratio of major complications to aBMI decreased significantly by an average of -2.7% per year. The ratio of patients with LOS > 2 days to aBMI decreased significantly by -27% per year. The ratio of SSI to aBMI increased significantly by 10.8% per year. CONCLUSIONS: From 2012 to 2020, the ratio of major complications and extended LOS following TKA as a function of BMI has decreased significantly, while the ratio of SSI as a function of BMI has doubled.

BACKGROUND: The relationship of chronic periprosthetic joint infection (PJI) treatment on the development and relapse of mood disorders remains largely unreported. This study aims to compare the incidence of different mental health disorders following antibiotic spacer placement for chronic PJI when compared to aseptic revisions and primary procedures. METHODS: Patients who underwent antibiotic spacer for septic total hip and knee arthroplasty (PJI THA/TKA) were identified in the PearlDiver Database using Current Procedure Terminology (CPT) codes for hip and knee antibiotic spacers. Patients who underwent aseptic revision and primary-THA/TKA were also identified using CPT codes. The incidences of depressive, anxiety, bipolar, psychotic, and stress disorders were identified within 2 years following the index procedures via Kaplan-Meier Analysis. RESULTS: The risk of depressive (hazard ratio (HR): 1.5; P < .001) and stress (HR: 1.5; P < .001) disorders were significantly higher in those who underwent PJI-THA when compared to aseptic revision, with the added risk of bipolar when compared to primary THA. The risk of depressive (HR: 1.6; P < .001), stress (HR: 1.4; P < .001), bipolar (HR: 1.3; P < .001), and psychotic disorders (HR: 1.5; P = .003) were significantly higher in those who underwent PJI-TKA when compared to aseptic revision, with the added risk of anxiety when compared to primary TKA. CONCLUSION: Patients who undergo spacer placement for septic-THA/TKA have a disproportionately higher incidence of mental health disorders within 2 years following surgery when compared those undergoing aseptic revisions and primary procedures. Due to this higher risk, physicians should strongly consider collaborative care with psychiatrists or mental health professionals. LEVEL OF EVIDENCE: III.

Same-day discharge pathways in total knee arthroplasty (TKA) are gaining popularity as a means to increase patient satisfaction and reduce overall costs, but these pathways have not been thoroughly evaluated in potentially at-risk populations, such as in patients ≥80 years old. The purpose of this study was to compare 90-day complications and mortality following same-day discharge after primary TKA in patients ≥80 years old and those <80 years old. Patients who underwent unilateral primary TKA, were discharged on postoperative day 0, and had a minimum 90-day follow-up were identified in a national insurance claims database (PearlDiver Technologies) using Current Procedural Terminology code 27447. These patients were stratified into two cohorts based upon age: (1) nonoctogenarians (<80 years old) and (2) octogenarians (≥80 years old). These cohorts were propensity matched based upon sex, Charlson comorbidity index, and obesity status. Univariate analysis was performed to determine differences in 90-day complications and mortality between the two cohorts. In total, 1,111 patients were included in each cohort. Both cohorts were successfully matched, with no observed differences in matched parameters for demographics or comorbidities. There was no significant difference in 90-day mortality between the two cohorts (p = 0.896). However, octogenarians were at significantly increased risk of postoperative atrial fibrillation (20.8 vs. 10.4%; p < 0.001), nonatrial fibrillation arrhythmias (8.4 vs. 5.6%; p = 0.009), pneumonia (4.5 vs. 2.2%; p = 0.002), stroke (3.1 vs. 1.7%; p = 0.037), heart failure (10.5 vs. 7.5%; p = 0.012), and urinary tract infection (UTI; 14.3 vs. 9.4%; p < 0.001) compared with the nonoctogenarian cohort. Relative to matched controls, octogenarians were at significantly increased risk of numerous 90-day medical complications following same-day primary TKA, including cardiopulmonary complications, stroke, and UTI. Clinicians should be cognizant of these complications and counsel patients appropriately when electing to perform same-day TKA in the octogenarian population.
