RESUMO
BACKGROUND: As total knee arthroplasty (TKA) further transitions toward an outpatient procedure, it becomes important to identify the resource utilization after TKAs at different outpatient facilities. The objective of this study was to determine the 90-day cost of patients who underwent TKAs at an ambulatory surgical center (ASC) or a hospital outpatient department (HOPD). METHODS: An observational cohort study was conducted using the Marketscan database with patients who had a TKA at an ASC or HOPD between January 1st, 2019, and October 2nd, 2021. The primary outcome was cost in a 90-day period (including the day of surgery), with inpatient admissions and ED visits as secondary outcomes. Multivariable regression analyses were conducted, adjusting for patient characteristics. RESULTS: The study population consisted of 47,261 patients with 7,874 ASC patients and 39,387 HOPD patients. 90-day costs for ASC patients were lower compared with HOPD patients ($35,634 ± 19,030 vs. $38,096 ± 24,389, P < 0.001). 90-day inpatient admission rates were lower for ASC than HOPD patients (2.5% vs. 4.8%, P < 0.001). 90-day ED visits for ASC patients were lesser compared with HOPD patients (8.9% vs. 12.7%, P < 0.001). CONCLUSION: Patients with TKAs at an ASC had an overall lower cost, inpatient admissions, and ED visits over a 90-day period compared with HOPD patients. Future consideration for which outpatient facilities patients have their TKA at is necessary as TKAs shift toward bundle payments and outpatient procedures.
RESUMO
BACKGROUND: Orthopedic Surgery Fellowship programs offer highly specialized training that varies based on the training environment and surgical experience. Additionally, for Adult Reconstruction programs, robotic-assisted surgery exposure has been a widely discussed topic. The purpose of this study was to determine the relative value of various factors to Adult Hip and Knee Fellowship applicants, and their perceptions of robotic-assisted arthroplasty. METHODS: We surveyed 780 applicants who applied to our fellowship to matriculate in 2020 to 2024. We received 158 responses (20.3% response rate). We assessed factors concerning people and perceptions, logistics, salary and benefits, program reputation and curriculum, and surgical experience. Additionally, we surveyed fellows' attitudes toward using robotic surgery and its impact on patient outcomes. RESULTS: The highest-rated factors were Level of Hands-On Operative Experience (4.83), Revision Hip Volume (4.72), Revision Knee Volume (4.71), Multiple Surgical Exposures to the Hip (4.59), and Clinical Case Variety (4.59). Respondents who were postfellowship matriculation placed significantly more value on Exposure to Multiple Attendings with Surgical Diversity (P = .01), and Anterior Hip Volume (P = .04), and less value on Geographic Location (P = .04) and Patient-Specific Instrumentation (P = .02) than prematriculates. Overall, 65% of applicants plan to or currently use robotics, 7.6% do not, and 27.2% said "Maybe". Those who plan to or currently use robotics most cited procedure fidelity, patient-preference, and marketability as reasons to use robotics. CONCLUSIONS: Hands-on surgical experience and revision volume were the most important factors for fellowship applicants. Applicants placed lower importance on robotics exposure and their perspectives on robotics in their future practice were highly variable. Our results will inform fellowship programs and future applicants what previous applicants have valued in their training to help guide fellowship program structure, resource management, as well as recruitment.

BACKGROUND: As technology-assisted surgery has boosted in the last decades, we aimed to investigate the factors affecting adoption and to predict the future utilization of technology among patients who underwent total knee arthroplasty (TKA). METHODS: Patients underwent TKA in 2017-2019 in the MarketScan Database were included. Percentage of technology-assisted surgery was calculated. Multivariable logistic regression models were performed to analyse the factors and make the prediction. RESULTS: Of 112,161 TKA procedures, 7.2% were technology-assisted. The proportion of technology-assisted TKA is expected to reach 50% by 2032. The West showed the highest proportion of technology-assisted TKA (12.3%), while the South had the lowest (5.7%). Over time, the Midwest showed the greatest increase in technology adoption (OR = 1.26 compared to the Northeast, 95% CI [1.15, 1.38]). CONCLUSIONS: Technology adoption rate of TKA will continue to increase for the next 20 years in the United States with a slight geographical variation.

BACKGROUND: The convergence of national priorities to reduce health-care costs and deliver high-value care warrants the need to examine health-care utilization. The objective of this study was to describe the costs associated with nonoperative procedures in the 1-year period leading up to primary total knee arthroplasty (TKA). METHODS: An observational cohort study was conducted using the IBM Watson Health MarketScan databases. Patients with late-stage knee osteoarthritis (OA) who underwent unilateral, isolated primary TKA from January 1, 2018, to December 31, 2019, were included. The main outcome was the cost of knee OA-related payments for identified nonoperative procedures in the 1-year period before surgery. Nonoperative procedures examined were (1) physical therapy (PT); (2) bracing; (3) intra-articular injections: professional fee, hyaluronic acid (IA-HA), and corticosteroids (IA-CS); (4) medication: nonsteroidal anti-inflammatory drugs (NSAIDs), opioids, and acetaminophen; and (5) knee-specific imaging. RESULTS: The study population included 24,492 TKA patients with a mean age of 60.4 ± 8.0 years. The average total cost of nonoperative procedures per patient was $1,355 ± $2,087. The most common nonoperative treatment prescribed was IA-CS (54.3%). The nonoperative procedure with the highest cost per patient was IA-HA ($1,019 ± $913 per patient). The total cost of nonoperative procedures was higher among female compared with male patients ($1,440 ± $2,159 versus $1,254 ± $1,992 per patient; p < 0.01). The highest costs were found for patients in the Northeast ($1,740 ± $2,437 per patient). A total of 14,346 (58.6%) and 7,831 (32.0%) of the patients had >1 and ≥3 nonoperative treatments, respectively. CONCLUSIONS: There is substantial variation in the type and the cost of nonoperative treatment for patients with late-stage OA. Future studies should investigate the effectiveness of nonoperative treatments at different stages of the disease. LEVEL OF EVIDENCE: Therapeutic Level III .

BACKGROUND: As health care shifts to a value-based model with bundled-payment methods, it is important to understand the costs and reimbursements of arthroplasty procedures that represent the largest expenditure of Medicare. The aim of the present study was to characterize the variation in (1) total hospital costs, (2) reimbursement, and (3) profit margin for different arthroplasty procedures. METHODS: The total hospital costs of total knee arthroplasty (TKA), total hip arthroplasty (THA), anatomic total shoulder arthroplasty (TSA), reverse shoulder arthroplasty (RSA), and total ankle arthroplasty (TAA) were calculated with use of time-driven activity-based costing at an orthopaedic institution from 2018 to 2020. The average reimbursement for each type of procedure was determined. Profit margin, defined as the reimbursement profit after direct costs, was calculated by deducting the average time-drive activity-based total hospital costs from the reimbursement value. Multivariate analyses were performed to evaluate the associations between costs, reimbursement, and profit margins. RESULTS: There were 13,545 arthroplasty procedures analyzed for this study, including 6,636 TKAs, 5,902 THAs, 346 TSAs, 577 RSAs, and 84 TAAs. Costs and reimbursement were highest for TAA. THA and TKA resulted in the highest profit margins, whereas RSA resulted in the lowest. The strongest associations with profit margin were private insurance (0.46547), age (-0.22732), and implant cost (-0.19240). CONCLUSIONS: THA and TKA had greater profit margins overall than TAA and upper-extremity arthroplasty in general. Profit margins for RSA, TSA, and TAA were all at least 28% lower than those for TKA or THA. Lower-volume arthroplasty procedures were associated with decreased profit margins. Study findings suggest that optimizing implant costs and length of stay are important for sustaining institutional fiscal health when performing shoulder and ankle arthroplasty surgery.

BACKGROUND: Lower-extremity arthroplasty constitutes the largest burden on health-care spending of any Medicare diagnosis group. Demand for upper extremity arthroplasty also continues to rise. It is necessary to better understand costs as health care shifts toward a bundled-payment accounting approach. We aimed (1) to identify whether variation exists in total cost for different types of joint arthroplasty, and, if so, (2) to determine which cost parameters drive this variation. METHODS: The cost of the episode of inpatient care for 22,215 total joint arthroplasties was calculated by implementing time-driven activity-based costing (TDABC) at a single orthopaedic specialty hospital from 2015 to 2018. Implant price, supply costs, personnel costs, and length of stay for total knee, total hip, anatomic total shoulder, reverse total shoulder, total elbow, and total ankle arthroplasty were analyzed. Individual cost parameters were compared with total cost and volume. RESULTS: Higher implant cost appeared to correlate with higher total costs and represented 53.8% of the total cost for an inpatient care cycle. Total knee arthroplasty was the least-expensive and highest-volume procedure, whereas total elbow arthroplasty had the lowest volume and highest cost (1.65 times more than that of total knee arthroplasty). Length of stay was correlated with increased personnel cost but did not have a significant effect on total cost. CONCLUSIONS: Total inpatient cost at our orthopaedic specialty hospital varied by up to a factor of 1.65 between different fields of arthroplasty. The highest-volume procedures-total knee and hip arthroplasty-were the least expensive, driven predominantly by lower implant purchase prices. CLINICAL RELEVANCE: We are not aware of any previous studies that have accurately compared cost structures across upper and lower-extremity arthroplasty with a uniform methodology. The present study, because of its uniform accounting process, provides reliable data that will allow clinicians to better understand cost relationships between different procedures.

BACKGROUND: Deep vein thrombosis (DVT) and pulmonary emboli (PE), known together as venous thromboembolic (VTE) disease remain major complications following elective hip and knee surgery. This study compares three chemoprophylactic regimens for VTE following elective primary unilateral hip or knee replacement, one of which was designed to minimize risk of post-operative bleeding. METHODS: Patients were randomized and stratified for hip vs. knee to receive A: variable dose warfarin (first dose on the night preceding surgery with subsequent target INR 2.0-2.5), B: 2.5 mg fondaparinux daily starting 6-18 h postoperatively, or C: fixed 1.0 mg dose warfarin daily starting 7 days preoperatively. All treatments continued until bilateral leg venous ultrasound day 28 ± 2 or earlier upon a VTE event. The study examined primary endpoints including leg DVT, PE or death due to VTE and secondary endpoints including effects on D-dimer, estimated blood loss (EBL) at surgery and hemorrhagic complications. RESULTS: Three hundred fifty-five patients were randomized. None was lost to follow-up. Taking 1.0 mg warfarin for seven days preoperatively did not prolong the prothrombin time (PT). Two patients in Arm C had asymptomatic distal DVT. One major bleed occurred in Arm B and one in Arm C (ischemic colitis). Elevated d-dimer did not predict delayed VTE for one year. CONCLUSIONS: Fixed low dose warfarin started preoperatively is equivalent to two other standards of care under study (95 % CI: -0.0428, 0.0067 for both) as VTE prophylaxis for the patients having elective major joint replacement surgery. TRIAL REGISTRATION: ClinicalTrials.gov identifier # NCT00767559 FDA IND: 103,716.
RESUMO
BACKGROUND: The U.S. Department of Justice's investigations into financial relationships between surgical device manufacturers and orthopaedic surgeons have raised the question as to whether surgeons can continue to collaborate with industry and maintain public trust. We explored postoperative patients' views on financial relationships between surgeons and surgical device manufacturers, their views on disclosure as a method to manage these relationships, and their opinions on oversight. METHODS: From November 2010 to March 2011, we surveyed 251 postoperative patients in the U.S. (an 88% response rate) and 252 postoperative patients in Canada (a 92% response rate) in follow-up hip and knee arthroplasty clinics with use of self-administered questionnaires. Patients were eligible to complete the questionnaire if their surgery (primary or revision hip or knee arthroplasty) had occurred at least three months earlier. RESULTS: Few patients are worried about possible financial relationships between their surgeon and industry (6% of surveyed patients in the U.S. and 6% of surveyed patients in Canada). Most patients thought that it is appropriate for surgeons to receive payments from manufacturers for activities that can benefit patients, such as royalties for inventions (U.S., 69%; Canada, 66%) and consultancy (U.S., 48%; Canada, 53%). Most patients felt that it is not appropriate for their surgeon to receive gifts from industry (U.S., 63%; Canada, 59%). A majority felt that their surgeon would hold patients' interests paramount, regardless of any financial relationship with a manufacturer (U.S., 76%; Canada, 74%). A majority of patients wanted their surgeon's professional organization to ensure that financial relationships are appropriate (U.S., 83%; Canada, 83%); a minority endorsed government oversight of these relationships (U.S., 26%; Canada, 35%). CONCLUSIONS: Most patients are not worried about possible financial relationships between their surgeon and industry. They clearly distinguish financial relationships that benefit current or future patients from those that benefit the surgeon or device manufacturer. They favor disclosure with professional oversight as a method of managing financial relationships between surgeons and manufacturers.

Abnormal femoral neck anteversion, previous proximal femoral osteotomies, and small femoral canals with metaphyseal/diaphyseal mismatch are commonly seen in patients with developmental dysplasia of the hip (DDH) and are ideal indications for using a modular femoral stem. The torsional stability of the fluted modular stem makes it the implant of choice for subtrochanteric osteotomy stabilization for reduction of high-riding DDH. Modularity optimizes proximal and distal implant stability while permitting adjustments to anteversion, offset, and leg length to provide custom biomechanical reconstruction of the DDH hip. Clinical results with few complications can be achieved when using this stem in complex DDH surgery.
