Background: Ankle arthroplasty has emerged as a viable alternative to ankle arthrodesis due in large part to recent advancements in both surgical technique and implant design. This study seeks to document trends of arthroplasty and arthrodesis for ankle osteoarthritis in New York State from 2009-2018 in order to determine if patient demographics play a role in procedure selection and to ascertain the utilization of each procedure and rates of complications. Methods: Patients 40 years and older from 2009-2018 were identified using International Classification of Diseases, Ninth and Tenth Revisions (ICD-9 and ICD-10), Clinical Modification (CM) diagnosis and procedure codes for ankle osteoarthritis, ankle arthrodesis, and ankle arthroplasty in the New York statewide planning and research cooperative system database. A trend analysis for both inpatient and outpatient procedures was performed to evaluate the changing trends in utilization of ankle arthrodesis and ankle arthroplasty over time. A multivariable logistic regression was used to assess the odds of receiving ankle arthrodesis relative to ankle arthroplasty. Complications were compared between inpatient ankle arthrodesis and arthroplasty using multivariable Cox proportional hazards regression. Results: A total of 3735 cases were included. Ankle arthrodesis increased by 25%, whereas arthroplasty increased by 757%. African American race, federal insurance, workers compensation, presence of comorbidities, and higher social deprivation were associated with increased odds of having an ankle arthrodesis vs an ankle arthroplasty. Compared with ankle arthroplasty, ankle arthrodesis was associated with increased rates of readmission, surgical site infection, acute renal failure, cellulitis, urinary tract infection, and deep vein thrombosis. Conclusion: Ankle arthroplasty volume has grown substantially without a decrease in ankle arthrodesis volume, suggesting that ankle arthroplasty may be selectively used for a different population of patients than ankle arthrodesis patients. Despite the increased growth of ankle arthroplasty, certain patient demographics including patients from minority populations, federal insurance, and from areas of high social deprivation have higher odds of receiving arthrodesis. Level of Evidence: Level III, retrospective cohort. [ABSTRACT FROM AUTHOR]

Introduction/Purpose: The two most common surgical procedures for end stage ankle arthritis patients who fail conservative management are arthrodesis and arthroplasty. The appropriateness of total ankle arthroplasty versus arthrodesis remains controversial. The long-term outcomes of current generation prostheses are not yet available and there is continued debate regarding the cost-benefit and risk-benefit analysis of each procedure. This study seeks to document rates of arthroplasty and arthrodesis for ankle osteoarthritis in New York in order to ascertain utilization of each procedure over time and stratification by patient demographics. Methods: Patients from 2009-2018 were identified using International Classification of Disease (ICD)-9 and 10 Clinical Modification (CM) codes for ankle osteoarthritis and Current Procedural Terminology or ICD-9 CM and ICD-10 Procedural Classification System procedural codes for ankle arthrodesis or ankle arthroplasty in the New York Statewide Planning and Research Cooperative System (SPARCS) database. SPARCS is an all-payer database collecting outpatient (emergency department, ambulatory surgery, and hospital-based clinic visits) and all inpatient claims in New York. A trend analysis was performed to determine if there was a shift towards either ankle arthrodesis or ankle arthroplasty over time. A multivariable logistic regression was performed to assess the impact of patient demographic factors on the likelihood of receiving arthrodesis versus arthroplasty. The variables included in the analysis were age, sex, race, ethnicity, Social Deprivation Index (linked by ZIP code), Charlson Comorbidity Index, and primary insurance type. Results: 3,735 cases were included in the trend analysis in years 2009-2018. In 2009, 220 (84%) procedures were ankle arthrodesis and 42 (16%) were ankle arthroplasty. By 2018, 274 (43.2%) were ankle arthrodesis and 360 (56.8%) were ankle arthroplasty (p<.0001). Ankle arthrodesis increased 25% over the study period while ankle arthroplasty increased 757%. The multivariable logistic regression showed older age (OR: 0.95, p<.0001) and females (OR: 0.71, p=.0003) had decreased odds of arthrodesis. African American race (OR: 1.63, p=.0459), federal insurance (OR: 1.72, p<.0001), worker's compensation (OR: 1.75, p=.0072), being from an area with higher social deprivation (OR: 1.01, p=.0004) or having >=1 Charlson comorbidities (OR: 1.4, p=.0007) was associated with increased odds of arthrodesis compared to arthroplasty. Conclusion: The present study demonstrates a substantial rise in ankle arthroplasty volume without a matching decrease in ankle arthrodesis volume over ten years. Patients who are wary of the motion limitation of arthrodesis and would previously have gravitated towards nonoperative management may now be finding a commonly performed, motion sparing alternative in arthroplasty. Ankle arthrodesis volume slightly increased, suggestive of nonequivalent patient populations undergoing these two procedures. There are apparent socioeconomic disparities in the utilization of these procedures, likely stemming from numerous nuanced factors but nevertheless also likely reflective of disparities in foot and ankle healthcare access.

Background: The purpose of this study is to further characterize the volume dependence of facilities and surgeons on morbidity and mortality after total hip arthroplasty (THA).Methods: Adults who underwent THA from 2009 to 2014 were identified using International Classification of Diseases, Ninth Revision, Clinical Modification and Procedural codes in the New York Statewide Planning and Research Cooperative System database. Complication rates were compared across surgeon and facility volumes using multivariable Cox proportional hazards regression controlling for factors such as the Social Deprivation Index. Surgeon and facility volumes were compared between the low and high volume using cutoffs established by prior research.Results: In total, 99,832 patients were included. Low volume facilities had higher rates of readmission, urinary tract infection (UTI), acute renal failure, pneumonia, surgical site infection (SSI), cellulitis, wound complications, deep vein thrombosis (DVT), in-hospital mortality, and revision. Low volume surgeons had higher rates of readmission, UTI, acute renal failure, pneumonia, SSI, acute respiratory failure, pulmonary embolism, cellulitis, wound complications, in-hospital mortality, cardiorespiratory arrest, DVT, and revision. African Americans, Hispanics, and those with federal insurance had increased rates of readmission. Those with ≥1 Charlson comorbidities or from areas of higher social deprivation had increased incidence of treatment by low volume surgeons and facilities.Conclusion: Both low volume facilities and surgeons performing primary THA have higher rates of readmission, UTI, acute renal failure, pneumonia, SSI, cellulitis, wound complications, DVT, in-hospital mortality, and revision. Demographic disparities exist between who is treated at low vs high volume surgeons and facilities placing those groups at higher risks for complications. [ABSTRACT FROM AUTHOR]
