RESUMEN

PURPOSE: Limited literature exists substantiating benefits of robotic arm-assisted total knee arthroplasty (raTKA) over conventional total knee arthroplasty (cTKA). This study compared postoperative pain, complications, and costs between patients undergoing raTKA and cTKA using large, propensity score-matched cohorts. We hypothesize that the raTKA cohort will be associated with lower pain, lower anemia, and similar cost and other complications. METHODS: A commercially available patient database was used for this study. Patients with raTKA and cTKA were identified with current procedural terminology and international classification of diseases (ICD-9/ICD-10) codes. Exclusions and propensity score matching were applied to mitigate confounding bias. Complication rates, costs, and postoperative opioid uses were then compared between groups. RESULTS: Compared with patients with cTKAs (n = 31,105), patients with raTKAs (n = 6,221) had less postoperative opioid use (p < 0.01), lower rates of postoperative acute renal failure (OR 0.71; p < 0.01), anemia (OR 0.75; p < 0.01), and periprosthetic joint infection (OR 0.59; p = 0.04), and lower index costs ($875 vs. $1,169, p < 0.01). CONCLUSION: RaTKA was associated with less postoperative pain and complications compared with cTKA.

RESUMEN

BACKGROUND: The knee joint remains the most affected joint in extra-intestinal manifestations of Crohn's disease (CD). Given the increasing prevalence of CD and overall demand for total knee arthroplasty (TKA), it is likely that an increasing number of patients with CD will require TKA. The purpose of this study was to assess the inpatient postoperative complication in patients with CD undergoing TKA. MATERIALS AND METHODS: We queried the Nationwide Inpatient Sample (NIS) database between the years of 2016 to 2019, including a total of 558,371 patients who underwent primary TKA. Among these, 1461 were in the CD group and 556,910 were in the non-CD group (controls). Data pertaining to demographics, length of stay (LOS), total healthcare cost, mortality, and in-hospital complications (blood loss anemia, blood transfusion, periprosthetic infection, periprosthetic dislocation, periprosthetic mechanical complication, acute renal failure, myocardial infarction, pneumonia, pulmonary embolism, deep vein thrombosis, superficial/deep surgical site infection, and wound dehiscence) were compared between the two groups. RESULTS: Patients diagnosed with CD had higher postoperative complications such as blood loss anemia (OR: 1.22, 95% CI: 1.07-1.39, p = 0.004), periprosthetic infection (OR: 1.80, 95% CI: 1.23-2.63, p = 0.006), and the need for blood transfusion (OR: 1.447, 95% CI: 1.01-2.06, p = 0.044) in comparison to the control group. In-hospital mortality and acute renal failure were similar in both groups. The CD group had a significantly prolonged LOS (2.54 vs. 2.35 days, p < 0.001). No statistically significant difference was noted concerning in-hospital charges between the two groups. CONCLUSIONS: CD patients undergoing TKA experienced increased LOS and postoperative complications. However, these complications were minor and did not affect total hospital cost. Further prospective cohort studies could build upon the findings described to continue to maximize outcomes in CD patients undergoing TKA, which might extend to other cohorts.

RESUMEN

INTRODUCTION: The number of reverse shoulder arthroplasties (RSA) performed each year is growing rapidly, especially in elderly patients and with expanded indications including geriatric proximal humerus fractures. As the elderly population grows and the number of RSA's annually continues to rise, there will be a proportionate number of adverse events and mortality. However, the rate of early mortality has consistently shown to be less than 1%, so a large-scale analysis of possible risk factors for post-operative mortality is warranted. METHODS: A retrospective multivariate analysis of 59,915 patients from the National Inpatient Sample database between 2016 and 2019 was performed. Patients who underwent RSA were identified based on ICD-10 code. Patients were divided into two groups, early mortality and no mortality. Early mortality was defined as those who died within the same admission. Patient demographics and medical comorbidities were evaluated. Hospital admission status was classified as elective or non-elective. Odds ratios for predictive variables were measured as a ratio of incidence between the early mortality and no mortality groups. RESULTS: The overall incidence of inpatient mortality was 0.07%. The incidence of mortality for elective admissions was 0.04% and for non-elective admissions was 0.34%. On univariate analysis, age greater than 75 years (p < 0.001), octogenarians (p < 0.001), nonagenarians (p < 0.001), and non-elective admission (p < 0.001) were associated with early mortality following RSA. Upon multivariate analysis, age greater than 75 years old had 4 times the odds of early mortality following RSA (OR 4.20; 95%CI (1.67, 10.60); p < 0.001) while non-elective admission had about 5 times the odds (OR 5.38; 95%CI (2.75, 10.53); p < 0.001). DISCUSSION: Age greater than 75 years old has 4-fold higher odds and non-elective admission has 5-fold higher odds of early mortality following RSA. Appropriate pre-operative counseling should be performed with elderly patients and those undergoing non-elective indications for RSA.

RESUMEN

Background: The literature is inconclusive regarding the potential complications of tranexamic acid (TXA), an antifibrinolytic drug, for total hip arthroplasty (THA). The purpose of this study is to compare complication rates and patient outcomes between THA patients administered TXA vs. THA patients not administered TXA. Methods: The TriNetX Research network was utilized to generate a cohort of adult patients who underwent THA between 2003 and 2024. These patients were categorized into two subgroups for the retrospective analysis: (1) patients who received TXA 24 h prior to THA (TXA), and (2) patients who did not receive TXA 24 h prior to total hip arthroplasty (no-TXA). The follow-up period was 30 and 90 days. Results: At 30 days following THA, the TXA patients had a reduced risk of transfusion (risk ratio (RR): 0.412; 95% confidence intervals (CI): 0.374, 0.453), reduced risk of DVT (RR: 0.856; CI: 0.768, 0.953), reduced risk of joint infection (RR: 0.808; CI: 0.710, 0.920), but a higher rate of periprosthetic fracture (RR: 1.234; CI: 1.065, 1.429) compared to patients who did not receive TXA. At 90 days following THA, TXA patients had a reduced risk of transfusion (RR: 0.446; CI: 0.408, 0.487), DVT (RR: 0.847; CI: 0.776, 0.924), and periprosthetic joint infection (RR: 0.894; CI: 0.815, 0.982) compared to patients who did not receive TXA. Patients who received TXA had higher rates of periprosthetic fracture (RR: 1.219; CI: 1.088, 1.365), acute postoperative anemia (RR: 1.222; CI: 1.171, 1.276), deep surgical site infection (SSI) (RR: 1.706; CI: 1.117, 2.605), and superficial SSI (RR: 1.950; CI: 1.567, 2.428) compared to patients who did not receive TXA. Conclusions: Patients receiving TXA prior to THA exhibited significantly reduced the prevalence of blood transfusions, DVT, and periprosthetic joint infection following THA. However, superficial SSI and periprosthetic fracture were seen with higher rates in the TXA cohort than in the no-TXA cohort.

RESUMEN

Introduction The inpatient postoperative outcomes of patients with colostomies following primary total knee arthroplasty (TKA) have not been well studied in the literature. The purpose of this study was to analyze how colostomy impacts the immediate postoperative outcomes of TKA. Our null hypothesis is that after correcting for common variables, a colostomy does not predispose patients undergoing TKA to surgical site infections (SSIs) and periprosthetic infections. Methods The National Inpatient Sample database was used to retrieve information on colostomy patients and patients without a colostomy who had undergone primary TKA from 2016 to 2019. Patients with colostomies were matched to a cohort of non-colostomy control groups in a 1:1 propensity score algorithm by age, sex, race, and pertinent comorbidities. Patient demographic characteristics, comorbidities, length of hospital stay (LOS), total hospital charges, and inpatient complications were compared. Results Following propensity score matching, 399 patients with colostomies were compared to 385 patients without a colostomy (control). The colostomy group had a prolonged LOS (3.15 ± 2.67 vs 2.44 ± 3.15 days, p<0.001) compared to the control group. Also, the colostomy group had significantly higher incidences of acute kidney injury (AKI) (6.02% vs 1.56%, odds ratio (OR): 4.04, 95% confidence interval (CI): 1.63-10.00, p<0.001), blood loss anemia (20.55% vs 13.25%, OR: 1.69, 95% CI: 1.16-2.48, p=0.008), and blood transfusions (4.01% vs 0.26%, OR: 16.04, 95% CI: 2.12-121.56, p<0.001). There was no difference in periprosthetic infection, superficial SSI, or deep SSI. Conclusion Patients with colostomies face a notably higher risk of experiencing AKI, blood loss anemia, and blood transfusion requirements during the immediate postoperative period following primary TKA. Despite the perceived risk of postoperative infection in colostomy patients, this patient population is not at an increased risk of developing periprosthetic infection, superficial SSI, or deep SSI following TKA.

RESUMEN

Introduction: The annual utilization of reverse total shoulder arthroplasty (RTSA) and anatomic total shoulder arthroplasty (ATSA) has grown exponentially, in part due to the expanded indications of RTSA. This evolution in shoulder arthroplasty prompts the need to evaluate outcomes between ATSA and RTSA. However, many other studies comparing outcomes between ATSA and RTSA lacked a large nationally-represented sample, a matched cohort analysis, or both. In this study, we compare outcomes between patients undergoing ATSA or RTSA in a large matched-cohort analysis. Methods: Patients undergoing RTSA or ATSA from the National Inpatient Sample database between 2016 and 2019 were identified. Groups were propensity-matched based on demographics and comorbidities. We compared medical and surgical complications, length of stay, and total hospital charges. T-tests and chi-square tests were performed for continuous and categorical variables, respectively. Odds ratios were calculated as a ratio between RTSA and ATSA groups. Results: Following matching, there were 38,782 patients in the ATSA group and 35,461 patients in the RTSA group. The RTSA group had higher odds of acute renal failure (OR 1.35), blood loss anemia (OR 1.39), and pneumonia (OR 1.19). There were no differences for myocardial infarction, pulmonary embolism, deep venous thrombosis, mortality, periprosthetic fracture, or dislocation. The RTSA group had higher odds of periprosthetic mechanical complication (OR 1.92), but lower odds of periprosthetic joint infection (OR 0.65). The mean length of stay and total hospital charges were both higher in the RTSA group (p < 0.001). Discussion: We found patients undergoing RTSA are at higher odds of inpatient medical complications, including acute renal failure and acute blood loss anemia. RTSA is associated with higher odds of short-term periprosthetic mechanical complications.

RESUMEN

INTRODUCTION: Studies investigating the link between mental health disorders and complications following total knee arthroplasty (TKA) have found worse outcomes in individuals with such disorders. Therefore, risk factors and outcomes following TKA in patients with schizophrenia should be better understood. This study aims to investigate cost and duration of hospital stay, inpatient complications, and mortality associated with TKA in patients with schizophrenia. MATERIALS AND METHODS: Utilizing the NIS database from 2016 to 2019, patients that underwent TKA were selected using ICD-10 codes. The selected patients were classified into a schizophrenia or control group and cost, hospitalization length, complications, and mortality rates were compared between the two groups in an unmatched and matched analysis. RESULTS: Our study dataset consisted of 558,371 patients that underwent a TKA during 2016 to 2019. 1,015 (0.2%) patients in the sample had a diagnosis of schizophrenia while the remaining 557,357 (99.8%) patients had no record of schizophrenia. An unmatched analysis found that schizophrenia patients had longer duration of hospital stay and greater charges incurred. Acute renal failure, myocardial infarction (MI), blood loss anemia, pneumonia, DVT, periprosthetic fracture, prosthetic dislocation, and periprosthetic infections were post-op complications with higher rates in the schizophrenia group. A matched cohort analysis found that schizophrenia patients still had longer duration of hospital stay and greater charges incurred. However, only acute renal failure, blood loss anemia, and pneumonia were found at higher rates in the schizophrenia group following TKA. CONCLUSIONS: Schizophrenia patients had a significantly longer hospital stay and increased charges acquired during their stay compared to the control group following TKA. Acute renal failure, blood loss anemia, and pneumonia were medical complications with an increased risk following TKA in patients with schizophrenia in a matched analysis. Increased care during the perioperative period following TKA in individuals with schizophrenia is thus warranted.

RESUMEN

Objectives: The rising popularity of reverse total shoulder arthroplasties (RTSA) demands attention to its growing costs on the healthcare system, especially with the implementation of bundled payments. Charges associated with patients' inpatient stays can be mitigated with a better understanding of the drivers of cost following RTSA. In this study, we evaluate potential pre-operative and post-operative factors associated with higher inpatient costs following RTSA. Methods: We identified 59,925 patients who underwent RTSA using the National Inpatient Sample between 2016 and 2019. Total inpatient hospital charges were collected, and patients were divided into "normal cost" or "high cost" groups. The high cost group was defined as patients with total costs greater than the 75th percentile. Univariate and multivariate analyses were performed on pre-operative demographic and comorbidity variables as well as post-operative surgical and medical complications to predict factors associated with higher costs. T-tests and Chi-squared tests were performed, and odds ratios were calculated. Results: The mean total charges were $141.213.93 in the high cost group and $59,181.94 in the normal cost group. Following multivariate analysis, non-white patients were associated with higher costs by 1.31-fold (P<0.001), but sex and age were not. Cirrhosis and non-elective admission had higher odds of higher costs by 1.56-fold (P<0.001) and 3.13-fold (P<0.001), respectively. Among surgical complications, there were higher odds of high costs for periprosthetic infection by 2.43-fold (P<0.001), periprosthetic mechanical complication by 1.28-fold (P<0.001), and periprosthetic fracture by 1.56-fold (P<0.001). Medical complications generally had higher odds of high costs than surgical complications, with deep vein thrombosis having nearly five times (P<0.001) and myocardial infarction almost four times (P<0.001) higher odds of high inpatient costs. Conclusion: Post-operative medical complications were the most predictive factors of higher cost following RTSA. Pre-operative optimization to prevent infection and medical complications is imperative to mitigate the economic burden of RTSA's.

RESUMEN

Objectives: Reverse total shoulder arthroplasty (RTSA) continues to increase in popularity as a surgical operation in the United States. As indications for this procedure expand, more attention is needed to evaluate perioperative risk factors and patient characteristics. Postoperative anemia requiring blood transfusion (BT) is a well-documented risk factor for increased in-house mortality although little has been studied on the relationship between RTSA and postoperative BT. The purpose of this study was to identify comorbidities and patient characteristics as risk factors for BT in patient's undergoing RTSA. Methods: Using the Nationwide Inpatient Sample (NIS) database, 59,925 RTSA patients (2016-2019) were analyzed, with 1.96% requiring postoperative BT. Demographics, comorbidities, and preoperative factors were compared between BT and non-BT groups via univariate and multivariate analyses. Results: Overall prevalence of blood transfusion in all patients was 1.96%. Male sex (OR 1.75, p < 0.001), Asian ethnicity (OR 1.96, p = 0.012), age >80 (OR 1.51, p < 0.001), age >90 (OR 2.26, p < 0.001), CKD (OR 1.94, p < 0.001), and Parkinson's disease (OR 2.08, p < 0.001) were associated with increased BT odds. Cirrhosis exhibited the highest impact (OR 5.7, p < 0.001). Conversely, Caucasian ethnicity (OR 0.76, p = 0.023), uncomplicated DM (OR 0.73, p = 0.002), tobacco-related disorders (OR 0.43, p < 0.001), BMI >30 (OR 0.8, p = 0.011), and elective procedures (OR 0.16, p < 0.001) decreased BT odds. Conclusion: These results were useful with identifying several risk factors that predispose to a higher risk of postoperative BT in patients undergoing RTSA including male sex, people of Asian descent, age > 80, CKD, Parkinson's disease, and cirrhosis. These findings provide clinicians with information that may be helpful with preoperative planning and perioperative management of complex patient populations.

RESUMEN

INTRODUCTION: Hip hemiarthroplasty (HHA) is one of the most common types of orthopedic surgery. With the prevalence and utilization of the surgery increasing year after year, this procedure is found to be associated with severe postoperative complications and eventually mortality. Thus, it is crucial to understand the factors that increase the risk of mortality following HHA. METHODS: Using the Nationwide Inpatient Sample (NIS) database, patients undergoing HHA from 2016 to 2019 were identified. This sample was stratified into a mortality group and a control group. The data regarding patients' demographics, co-morbidities, and associated complications were compared between the groups. RESULTS: Of the 84,067 patients who underwent the HHA procedures, 1,327 (1.6%) patients died. Additionally, the mortality group had a higher percentage of patients who were non-electively admitted (P < 0.001) and diabetic patients with complications (P < 0.001), but lower incidences of tobacco-related disorders (P < 0.001). Significant differences were also seen in age (P < 0.001), length of stay (P < 0.001), and total charges (P < 0.001) between the two groups. Preoperatively, those aged > 70 years (OR: 2.11, 95% CI [1.74, 2.56], P < 0.001) had diabetes without complications (OR: 0.32, 95% CI [0.23, 0.44], P < 0.001), tobacco-related disorders (OR: 0.24, 95% CI [0.17, 0.34], P < 0.001) and increased rates of mortality after HHA. Postoperatively, conditions, such as pulmonary embolisms (OR: 6.62, 95% CI [5.07, 8.65], P < 0.001), acute renal failure (OR: 4.58 95% CI [4.09, 5.13], P < 0.001), pneumonia (95% CI [2.72, 3.83], P < 0.001), and myocardial infarctions (OR: 2.65, 95% CI [1.80, 3.92], P < 0.001) increased likelihood of death after undergoing HHA. Patients who were electively admitted (OR: 0.46 95% CI [0.35, 0.61], P < 0.001) had preoperative obesity (OR: 0.67, 95% CI [0.44, 0.84], P = 0.002), and a periprosthetic dislocation (OR: 0.51, 95% CI [0.31, 0.83], P = 0.007) and were found to have a decreased risk of mortality following THA. CONCLUSIONS: Analysis of pre- and postoperative complications relating to HHA revealed that several comorbidities and postoperative complications increased the odds of mortality. Old age, pulmonary embolisms, acute renal failure, pneumonia, and myocardial infraction enhanced the odds of post-HHA mortality.

RESUMEN

Background: Early dislocation following primary total hip arthroplasty (THA) is a rare but devastating complication and represents a source of patient morbidity and financial burden to the healthcare system. The objective of this study was to identify patient characteristics and comorbidities that are associated with increased early in-hospital dislocation rates following primary THA. Methods: A retrospective cohort study was conducted using patient data from the Nationwide Inpatient Sample (NIS) database; we identified patients who had undergone THA from 2016 to 2019 and compared those with an early periprosthetic dislocation prior to discharge to those without. The patient characteristics and comorbidities were compared using univariate analysis with a subsequent investigation of statistically significant variables using multivariate analysis. The variables were compared using chi square, Fisher's exact test, and independent sample t-tests with data assessed using odds ratio with 95% confidence intervals. Results: A total of 5151 patients sustained an early dislocation compared to 362,743 who did not. Those who sustained an in-hospital dislocation were more likely to share the following characteristics: female sex (OR 1.21, p < 0.01), age > 70 (OR 1.45, p < 0.01), Caucasian ethnicity (OR 1.22, p < 0.01), SLE (OR 1.87, p < 0.01), and Parkinson's disease (OR 1.93, p < 0.01). Certain characteristics were also associated with decreased odds of having an in-hospital dislocation including elective surgery (OR 0.14, p < 0.01), tobacco use (OR 0.8, p < 0.01), diabetes without complications (OR 0.87, p < 0.01), and a history of heart valve replacement (OR 0.81, p < 0.01). The length of stay was significantly longer (4.7 days vs. 2.3 days) as was the total hospital charges (USD $101,517 vs. USD $66,388) for the early in-hospital dislocation group. Conclusions: Several patient characteristics and comorbidities are associated with early in-hospital dislocation episodes following total hip arthroplasty including female sex, age > 70, non-elective surgery, SLE, and Parkinson's. This information may be useful to help guide intraoperative implant selection and/or postoperative protocol in select patient populations to limit early instability as well as decrease the financial burden associated with this postoperative complication.

RESUMEN

INTRODUCTION: Discrepant data exists regarding the outcomes following total knee arthroplasty (TKA) with a prior anterior cruciate reconstruction (ACLR). The purpose of our study was to compare surgical and medical outcomes in the patients with prior ACLR undergoing TKAs compared to a matched control group of the patients who had undergone TKAs without prior ACLR. We hypothesized that the patients with prior ACLR would have inferior clinical outcomes. MATERIAL/METHODS: We retrospectively queried the PearlDiver-database for patients who underwent TKA following ACLR from 2011 to 2020. We used propensity-score matching to create two cohorts. The two-sided independent t-test and Chi-Squared test were used. RESULTS: We identified 2,174 patients who had prior ACLR before the TKAs. There were another 1,348,870 patients who did not have ACLR before the TKAs. After matching, each group had 2,171 patients. The ACLR-TKA group had significantly lower rates of aseptic revision at 2 years (1.2% vs. 4.0%, OR 0.3, p < 0.01), PJI requiring antibiotic spacer at 2 years (0.3% vs. 0.8%, OR 0.35, p = 0.02), and MUA at 90 days (0.4% vs. 7.5%, OR 0.05, p < 0.01). The rate of wound disruption was lower for the ACLR-TKA group at 90 days (p = 0.03) as were several medical complications including AKI at 90 days (p < 0.01), DVT at 90 days (p < 0.01), pneumonia at 90 days (0.04), and required blood transfusion at 90 days (p < 0.01). CONCLUSION: These results differed from our expectations. Within the limitations of the study, we are unable to determine the factors for the lower complications in the ACLR-TKA group. The data from this study are different from what had been reported in the previous studies.

RESUMEN

PURPOSE: Although a trend of an improved alignment with robotic total hip arthroplasty (THA) over conventional methods has surfaced from recent series, it is unknown whether these results translate into meaningful enhancements in postoperative outcomes. To address this lack in the literature, we compared the perioperative morbidity and mortality with robotic and conventional THA in a large national cohort of 367,894 patients. We hypothesized that no significant differences would exist in the outcomes between the two groups. METHODS: Records were extracted from 2016-2019 from the National Inpatient Sample (NIS) database Healthcare Cost and Utilization Project which is the largest in-patient database in the United States. From 367,894 THAs, robotics were employed for 7,863 patients. The remaining 360,031 conventional THAs served as controls. The two groups were compared for demographics, admission, and hospital stay details including costs, and mortality and morbidity data including medical and surgical complications. Descriptive statistics were used for demographic data while analytical statistics including t-tests, chi-squared tests, Fischer exact test, and Pearson chi-squared tests were used for perioperative outcomes. Statistical significance was set at p<0.005. RESULTS: Demographic distributions between robotic and conventional THA groups displayed similar age and sex characteristics. Shorter mean lengths of stay (1.87 days) were seen in robotic THA versus conventional THA (2.33 days) while higher costs were noted for the former (mean $68,686.71 vs $66,840.39) (p<0.005). Low overall mortality (0.03% robotic, 0.09% conventional) was seen in both groups (p>0.005). Higher comparative incidences of anemia, acute renal failure, and pneumonia were seen in conventional THA (p<0.005) while no significant differences were noted for other complications including myocardial infarction, pulmonary embolism, deep vein thrombosis, and cardiac arrest (p>0.005). Among others, lower dislocation rates, mechanical complications, periprosthetic joint infection, and periprosthetic fractures were seen with robotic THA (p<0.005). Wound complications and superficial infection rates did not differ between the two groups (p>0.005). CONCLUSIONS: Evidence has emerged from our results to support more routine adaptation of the robotic option of performing a THA. These can be based on lower local, systemic, and mechanical complications as demonstrated by the present study. Further evaluation of these results in follow-up would help establish the foothold of robotic surgery in total hip replacement in the modern context.

RESUMEN

INTRODUCTION: With innovations in transplant medicine and longer life expectancies in solid organ transplant (SOT) recipients, the incidence of shoulder arthroplasty is predictably rising in this population. Reverse shoulder arthroplasty (RSA) has become increasingly popular due to advances in prosthetic design with expanded indications. While previous studies have examined shoulder arthroplasty in SOT patients, information specifically related to RSA patients is largely unexplored. We aim to analyze the demographics and characteristics of SOT patients who have undergone RSA while assessing inpatient complication rates, length of stay (LOS), and hospital costs in these patients compared to a matched cohort of non-transplant patients. METHODS: The National Inpatient Sample (NIS) Database was utilized to identify all patients undergoing RSA from 2016 to 2019. We generated propensity-matched groups based on pre-operative variables (diabetes, tobacco use, sex, age, and obesity) to compare complications, LOS, and inpatient costs between the SOT and control groups. T-tests and Chi-squared tests were performed where appropriate and odds ratios were calculated. RESULTS: We identified 59925 patients who underwent RSA. Among those, 59769 patients (99.7%) did not have a SOT and 156 patients (0.26%) had a history of SOT. Patients in the SOT group were younger than the control group (67.0 versus 71.4 years, p<0.001). The SOT group were more likely males compared to the control group (53.8% versus 39.3%, p<0.001). Following 1:1 matching, there were 156 patients in each group. The SOT group had a higher risk of acute renal failure (ARF) compared to the control group (OR 9.41, 95% CI (2.13-41.49), p<0.001). The LOS (p<0.001) and inpatient costs (p<0.001) were higher in the SOT group. CONCLUSION: For RSA, SOT patients are younger and more likely male compared to those without SOT. Inpatient medical and surgical complications are similar between SOT and non-SOT patients, except SOT patients have a higher risk of ARF. SOT patients tend to have longer LOS and higher inpatient costs than non-SOT patients.

RESUMEN

INTRODUCTION: With a progressive rise in the number of total hip arthroplasties (THA) over the past decades, the proportion of patients sustaining peri-prosthetic fractures (PPF) has been substantially increasing. In this context, the need for clearly understanding the factors predisposing patients to PPF following THA and the impact of these adverse complications on the overall healthcare burden cannot be understated. MATERIALS AND METHODS: Based upon the Nationwide Inpatient Sample (NIS) database, the patients who underwent THA in the United States between 2016 and2019 (with ICD-10 CMP code) were identified. The patients were divided into 2 groups; group A - patients who sustained PPF and group B - those who did not. The information about the patients' demographic profile, medical comorbidities; and hospital admission (including length of stay and expenditure incurred) were analysed; and compared between the 2 groups. RESULTS: Overall, 367,890 patients underwent THA, among whom 4,425 (1.2%) sustained PPF (group A). The remaining patients were classified under group B (363,465 patients). On the basis of multi-variate analysis (MVA), there was a significantly greater proportion of females, elderly patients, and emergent admissions (p < 0.001) in group A. The length of hospital stay, expenditure incurred and mortality were also significantly higher (p = 0.001) in group A. Based on MVA, Down's syndrome (odd's ratio 3.15, p = 0.01), H/O colostomy (odd's ratio 2.09, p = 0.008), liver cirrhosis (odd's ratio 2.01, p < 0.001), Parkinson's disease (odd's ratio 1.49, p = 0.004), morbid obesity (odd's ratio 1.44, p < 0.001), super obesity (odd's ratio 1.49, p = 0.03), and H/O CABG (coronary artery bypass graft; odd's ratio 1.21, p = 0.03) demonstrated significant association with PPF (group A). CONCLUSION: Patients with PPF require higher rates of emergent admission, longer hospital stay and greater admission-related expenditure. Female sex, advanced age, morbid or super obesity, and presence of medical comorbidities (such as Down's syndrome, cirrhosis, Parkinson's disease, previous colostomy, and previous CABG) significantly enhance the risk of PPF after THA. These medical conditions must be kept in clinicians' minds and close follow-up needs to be implemented in such situations so as to mitigate these complications.

RESUMEN

Background: Periprosthetic fractures after total knee arthroplasty (TKA) are a challenging problem due to complex fracture patterns, poor bone quality, and a high-risk patient population. Treatment of both periprosthetic fractures and aseptic complications can include revision TKA. In this study, we compared systemic and orthopaedic complications following periprosthetic fracture associated revision TKA to aseptic revision TKA. Methods: This is a retrospective cohort study using data from the years 2010-2020 from a national administrative claims database. Billing codes were used to identify revision TKAs with a diagnosis of periprosthetic fracture or aseptic complications (loosening, dislocation, arthrofibrosis, osteolysis, or prosthetic wear) within one year prior to revision. Pertinent systemic complications and rates of repeat revision TKA, periprosthetic infection, and repeat fractures were compared between the two groups. Results: We identified 9891 periprosthetic fracture associated revision TKAs and 47,071 aseptic revision TKAs. Our study found higher rate of systemic complications including AKI, DVT, wound disruption, hematoma, and surgical site infections in periprosthetic fracture associated revision TKA compared to aseptic revision TKA. Furthermore, we found higher rates of repeat revision TKA, periprosthetic infections, and repeat periprosthetic fractures in fracture associated revision TKA group compared to aseptic revision group. Conclusions: Our work highlights the significant short- and long-term complications associated with periprosthetic fracture associated revision TKA. Future working comparing functional outcomes and optimal surgical techniques are needed.

RESUMEN

INTRODUCTION: This study elaborates on previous research to compare length of stay, complication rates, and total cost between patients undergoing robotic assisted total knee arthroplasty (rTKA) and conventional total knee arthroplasty (cTKA). We hypothesized that patients undergoing rTKA would have reduced length of stay, lower complication rates, improved perioperative outcomes, and higher total healthcare costs than those undergoing cTKA. METHODS: Data were collected from the National Inpatient Sample Database Healthcare Cost and Utilization Project between the years 2016-2019. Patients undergoing rTKA and cTKA were identified under International Classification of Diseases, 10th revision codes (ICD-10-CM/PCS). Length of stay, specific complications, and total costs were examined at time point. SPSS (v 27.0 8, IBM Corp. Armonk, NY) was utilized to compare demographic and analytical statistics between rTKA and cTKA. rTKA and cTKA were compared both before and after propensity matching. RESULTS: 17,249 rTKA (3.09%) and 541,122 cTKA (96.91%) were included. Compared to cTKA patients, rTKA patients had reduced average length of stay of 1.91 days (p < 0.001), higher average total cost of $67133.34 (p < 0.001), reduced periprosthetic infection (OR = 0.027, p < 0.001), periprosthetic dislocation (OR = 0.117, p < 0.001), periprosthetic mechanical complication (OR = 0.315, p < 0.001), pulmonary embolism (OR = 0.358, p < 0.001), transfusion (OR = 0.366, p < 0.001), pneumonia (OR = 0.468, p = 0.002), deep vein thrombosis (OR = 0.479, p = 0.001), and blood loss anemia (OR = 0.728, p < 0.001). These differences remained statistically significant even after propensity matching. CONCLUSIONS: This study supports our hypothesis that rTKA is associated with fewer complications, but higher average total cost than cTKA. Our study shows that rTKA can be safely performed in older and sicker patients. Future studies assessing the impacts of these findings on patient reported outcomes would provide further insight into the benefits of rTKA. Furthermore, identifying patient specific factors that place them at risk for increased complications with cTKA as opposed to rTKA could provide surgeons insight on the method of TKA that maximizes patient outcomes while minimizing healthcare cost.

RESUMEN

BACKGROUND: Comorbid cardiovascular diseases have been associated with poor outcomes in total knee arthroplasty (TKA); however, our understanding of TKA with prior cardiac treatment procedures has largely been undocumented. In this study, we examined TKA patients who had undergone different cardiac interventions that addressed their condition. The purpose was to characterize and compare outcomes for a growing patient population not yet analyzed. MATERIALS AND METHODS: The 2016-2019 Nationwide Inpatient Sample database was queried for 558,256 patients who had TKA (ICD-10CM). Backgrounds significant for pacemaker [PM] (n = 8025), coronary artery bypass [CABG] (n = 12,683), heart valve surgery [HV] (n = 4125), or coronary stent [CS] (n = 19,483) were compared against those without, across demographics, admission information, and various complications. RESULTS: Cardiac interventions were associated with increased age, male gender, length of stay, and cost of care. CABG, and Stent groups had more diabetics, but HV had significantly fewer (p = 0.008). PM and HV had significantly less tobacco use and, in addition to CABG, less obesity. Postoperatively, mortality was elevated in the PM [Odds ratio (OR) 2.89, p = 0.008], CABG (OR 2.53, p = 0.006) and CS group (OR 1.94, p = 0.018), but not HV. Myocardial infarctions were elevated in the CABG (OR 3.874) and CS group (OR 5.11) (p < 0.001). PM, HV, and CS had increased odds of periprosthetic fracture by 2.15-fold (p < 0.001), 2.09-fold (p < 0.001), 1.29-fold (p = 0.011) respectively. HV saw increased periprosthetic mechanical complications (OR 1.48, p = 0.006). CABG increased the odds of deep surgical site infection 14.23-fold and CS 9.22-fold (p < 0.001). Postoperative pneumonia was increased in PM, CABG, and CS groups (OR 2.15,), (OR 2.21,), (OR 1.64,) (p < 0.001). CONCLUSIONS: Patients who have undergone cardiac intervention are generally at risk for adverse stays. Furthermore, risk factors and complications vary between the groups. Our analysis emphasizes the importance of individualized medical care and as a basis for electing and informing patients for TKA.

RESUMEN

Purpose: The aim of this study was to identify potential risk factors for myocardial infarction immediately following total hip arthroplasty. Methods: The 2016-2019 Nationwide Inpatient Sample database was used to identify patients who underwent primary total hip arthroplasty (THA) and suffered a myocardial infarction (MI). Patient data including demographics, admission, and comorbidities were recorded. Univariate analysis and subsequent multivariate logistic regression were performed to determine which circumstances affected the odds of MI. Results: A total of 367,890 patients were identified for THA with 142 of those also having a myocardial infarction. Those who experienced an MI had increased length of stay, total charges, and generally negative dispositions compared to their non-MI counterparts (p < 0.001). Through regression analysis, factors that increased the odds of MI included older age [odds ratio (OR) 1.59, 95 % confidence interval (CI) 1.49-1.70], a female sex (OR 1.46, 95 % CI 1.37-1.55), previous coronary artery bypass graft (OR 1.20, 95 % CI 1.01-1.43), obesity (OR 1.12, 95 % CI 1.04-1.21), colostomy (OR 2.07, 95 % CI 1.21-3.56), and Parkinson's disease (OR 1.48, 95 % CI 1.13-1.95). Factors that decreased that risk included elective admission (OR 0.21, 95 % CI 0.19-0.22) and a tobacco related disorder (OR 0.69, 95 % CI 0.63-0.76). Conclusions: Patient risk for myocardial infarction following total hip arthroplasty varies in part based on their background and comorbidities. These findings can be used to better recognize those who should receive further precautions and tailor proper treatment strategies for THA.

RESUMEN

INTRODUCTION: In this study, we evaluate how race corresponds to specific complications and costs following total knee arthroplasty (TKA). Our hypothesis was that minority patients, comprising Black, Asian, and Hispanic patients, would have higher complication and revision rates and costs than White patients. METHODS: Data from 2014 to 2016 were collected from a large commercial insurance database. TKA patients were assigned under Current Procedural Terminology (CPT-27447) and International Statistical Classification of Diseases (ICD-9-P-8154) codes. Minority patients were compared to White patients before and after matching for age, gender, and tobacco use, diabetes, and obesity comorbidities. Standardized complications, revisions, and total costs at 30 days, 90 days, and 1 year were compared between the groups using unequal variance t tests. RESULTS: Overall, 140,601 White (92%), 10,247 Black (6.7%), 1072 Asian (0.67%), and 1725 Hispanic (1.1%) TKA patients were included. At baseline, minority patients had 7-10% longer lengths of stay (p = 0.0001) and Black and Hispanic patients had higher Charlson and Elixhauser comorbidity indices (p = 0.0001), while Asian patients had a lower Elixhauser comorbidity index (p < 0.0001). Black patients had significantly higher complication rates and higher rates of revision (p = 0.03). Minority patients were charged 10-32% more (p < 0.0001). Following matching, all minority patients had lengths of stay 8-10% longer (p = 0.001) and Black patients had higher Charlson and Elixhauser comorbidity indices (p < 0.0001) while Asian patients had a lower Elixhauser comorbidity index (p = 0.0008). Black patients had more equal complication rates and there was no significant difference in revisions in any minority cohort. All minority cohorts had significantly higher total costs at all time points, ranging from 9 to 31% (p < 0.0001). CONCLUSION: Compared to White patients, Black patients had significantly increased rates of complications, along with greater total costs, but not revisions. Asian and Hispanic patients, however, did not have significant differences in complications or revisions yet still had higher costs. As a result, this study corroborates our hypothesis that Black patients have higher rates of complications and costs than White patients following total knee arthroplasty and recommends efforts be taken to tackle health inequities to create more fairness in healthcare. This same hypothesis, however, was not supported when evaluating Asian and Hispanic patients, probably because of the few patients included in the database and deserves further investigation.
