Comparisons of patient-reported outcomes (PROs) based on surgical approach for total hip arthroplasty (THA) in the United States are limited to series from single surgeons or institutions. Using ...prospective data from a large, multicenter study, we compare preoperative to postoperative changes in PROs between posterior, transgluteal, and anterior surgical approaches to THA.
Patient-reported function, global health, and pain were systematically collected preoperatively and at 1, 3, and 6 months postoperatively from patients undergoing primary THA at 26 sites participating in the Comparative Effectiveness of Pulmonary Embolism Prevention After Hip and Knee Replacement (ClinicalTrials.gov: NCT02810704). Outcomes consisted of the brief Hip disability and Osteoarthritis Outcome Score, the Patient-Reported Outcomes Measurement Information System Physical Health score, and the Numeric Pain Rating Scale. Operative approaches were grouped by surgical plane relative to the abductor musculature as being either anterior, transgluteal, or posterior.
Between 12/12/2016 and 08/31/2019, outcomes from 3018 eligible participants were examined. At 1 month, the transgluteal cohort had a 2.2-point lower improvement in Hip disability and Osteoarthritis Outcomes Score (95% confidence interval, 0.40-4.06; P = .017) and a 1.3-point lower improvement in Patient-Reported Outcomes Measurement Information System Physical Health score (95% confidence interval, 0.48-2.04; P = .002) compared to posterior approaches. There was no significant difference in improvement between anterior and posterior approaches. At 3 and 6 months, no clinically significant differences in PRO improvement were observed between groups.
PROs 6 months following THA dramatically improved regardless of the plane of surgical approach, suggesting that choice of surgical approach can be left to the discretion of surgeons and patients without fear of differential early outcomes.
Orthopaedic residency education has changed substantially in recent decades because of the imposition of the 80-hour work week, a decrease in quality and quantity of general surgical education, ...regulations mandating closer trainee supervision, and an expansion of orthopaedic subspecialty rotations. These factors pose a challenge in efforts to prepare competent, confident, cautious, caring, and communicative orthopaedic residents within the traditional 5-year program. Evidence suggests that contemporary graduates are more intelligent, better balanced in life and work, and more in touch with humanistic aspects of medicine than were earlier graduates. Yet insufficient competence and confidence in surgical skills after residency and a lack of "ownership" of patient care have become an increasing concern of educators and trainees. The concept of 10,000 hours of deliberate practice to achieve mastery of a technical skill applies to orthopaedic residency education. A different approach to graduate medical education must address the critical minimum training time required to achieve the necessary skills to support independent medical and surgical practice.
Background
Reporting of complications after total hip arthroplasty (THA) is not standardized, and it is done inconsistently across various studies on the topic. Advantages of standardizing ...complications include improved patient safety and outcomes and better reporting in comparative studies.
Questions/purposes
The purpose of this project was to develop a standardized list of complications and adverse events associated with THA, develop standardized definitions for each complication, and stratify the complications. A further purpose was to validate these standardized THA complications.
Methods
The Hip Society THA Complications Workgroup proposed a list of THA complications, definitions for each complication, and a stratification scheme for the complications. The stratification system was developed from a previously validated grading system for complications of hip preservation surgery. The proposed complications, definitions, and stratification were validated with an expert opinion survey of members of The Hip Society, a case study evaluation, and analysis of a large administrative hospital system database with a focus on readmissions.
Results
One hundred five clinical members (100%) of The Hip Society responded to the THA complications survey. Initially, 21 THA complications were proposed. The validation process reduced the 21 proposed complications to 19 THA complications with definitions and stratification that were endorsed by The Hip Society (bleeding, wound complication, thromboembolic disease, neural deficit, vascular injury, dislocation/instability, periprosthetic fracture, abductor muscle disruption, deep periprosthetic joint infection, heterotopic ossification, bearing surface wear, osteolysis, implant loosening, cup-liner dissociation, implant fracture, reoperation, revision, readmission, death).
Conclusions
Acceptance and use of these standardized, stratified, and validated THA complications and adverse events could advance reporting of outcomes of THA and improve assessment of THA by clinical investigators.

Abstract Background Tranexamic acid (TXA) has been associated with decreased blood loss and transfusion after total hip arthroplasty (THA) and total knee arthroplasty (TKA). The purpose of this study ...was to examine both transfusion utilization and the economic impact of a Process Improvement Project implementing TXA for THA and TKA. Methods After standardization of TXA administration in THA and TKA patients, retrospective data were compared from 12 consecutive months before (group A, n = 336 procedures) and after (group B, n = 436 procedures) project initiation. Results TXA administration increased with project implementation (group A = 3.57%, group B = 86.01%) and was associated with reductions in perioperative hemoglobin decrement (20.2%), patients transfused (45%), and number of units transfused per patient (61.9%). Cost savings were notable per patient ($128) and annually program wide ($55,884) with the primary THA subgroup contributing the most to the savings. No increase in adverse effects was observed. Conclusion Standardized administration of TXA is an effective and economically favorable blood-reduction strategy for patients undergoing elective THA or TKA. Although reduction in transfusions with TXA may be greater after TKA, the economic and clinical impact of transfusion reduction is more substantial in THA patients.
Total joint arthroplasty is a highly successful surgical procedure for patients with painful arthritic joints. The increasing prevalence of the procedure is generating significant expenditures in the ...American healthcare system. Healthcare payers, specifically the Center for Medicare and Medicaid Services, currently target total joint arthroplasty as an area for healthcare cost-savings initiatives, resulting in increased scrutiny surrounding orthopaedic care, health resource utilization, and hospital readmissions. Identifying the complications associated with total hip and total knee arthroplasty that result in readmissions will be critically important for predictive modeling and for decreasing the number of readmissions following total joint arthroplasty. Additionally, improving perioperative optimization, providing seamless episodic care, and intensifying posthospital coordination of care may result in a decreasing number of unnecessary hospital readmissions. Identified modifiable risk factors that significantly contribute to poor clinical outcome following total joint arthroplasty include morbid obesity; poorly controlled diabetes and nutritional deficiencies; Staphylococcus aureus colonization; tobacco use; venous thromboembolic disease; cardiovascular disease; neurocognitive, psychological, and behavioral problems; and physical deconditioning and fall risk. Both clinical practice and research will be enhanced if there is standardization of defined total joint arthroplasty complications and utilization of stratification schemes to identify high-risk patients. Subsequently, clinical intervention would be warranted to address modifiable risk factors before proceeding with total joint arthroplasty.
The influence of anesthetic type on mental health after total hip arthroplasty (THA) is poorly understood. Adverse effects of general anesthesia (GA) on cognition following major non-cardiac surgery ...are well known, but mental health following THA is less well-studied. We hypothesized that neuraxial anesthesia (NA) would provide favorable mental health profiles compared with GA after THA.
Prospectively collected Patient-Reported Outcomes Measurement Information System-10 (PROMIS) Global Mental Health (GMH) scores at preoperative baseline, and 1, 3, and 6 months after THA were accessed on 4,353 patients in the Pulmonary Embolism Prevention After HiP and KneE Replacement (PEPPER) Trial (ClinicalTrials.gov: NCT02810704). Anesthesia was categorized as: general (GA), neuraxial (NA), and neuraxial with peripheral block (NAP). The GMH was assessed longitudinally and compared between groups.
Postoperative GMH improved (P < .05) over preoperative in every anesthetic group. Groups receiving NA had higher baseline GMH scores. Improvement in GMH was diminished after GA alone and plateaued after 1 month. Adding NA or peripheral nerve block to GA conferred additional benefit to GMH improvement.
Patient-perceived mental health improves significantly after THA regardless of anesthetic type. Patients who have higher baseline GMH scores more commonly received NA, likely due to nonsurgical care determinants; these differences in mental wellness persisted at follow-up. Adjunctive NA or peripheral nerve block favored GMH improvement, whereas solitary GA diminished GMH improvement, which plateaued after 1 month. Substantial mental health benefits of THA may overshadow subtle differences in GMH attributable to anesthetic type.
Orthopaedic education should produce surgeons who are competent to function independently and can obtain and maintain board certification.
Contemporary orthopaedic training programs exist within a ...fixed 5-year time frame, which may not be a perfect match for each trainee.
Most modern orthopaedic residencies have not yet fully adopted objective, proficiency-based, surgical skill training methods despite nearly 2 decades of evidence supporting the use of this methodology.
Competency-based medical education backed by surgical simulation rooted in proficiency-based progression has the potential to address surgical skill acquisition challenges in orthopaedic surgery.
The recent focus on competency-based medical education has heralded a true change in U.S. medical education. Accelerating the transition from medical school to residency may reduce student debt, ...encourage competency-based educational advancement, and produce residency graduates better prepared for the independent and unsupervised practice of medicine. With some purposeful design considerations, innovative time-variable programs or fixed-time accelerated tracks can be implemented within current regulatory parameters and without major alteration of existing institutional regulatory guidelines, state licensing requirements, or specialty certification requirements. Conferring an MD degree in less than 4 full academic years provides opportunities to customize and find greater value in the fourth year of medical school as well as to redeploy time from undergraduate medical education to graduate medical education; this could shorten the overall time to completion of training and/or provide for customization of training in the final years of residency. In this article, the authors discuss the regulatory requirements for successful implementation; consider issues related to "off-cycle" graduates advancing to residency training outside of the Match; and share examples of 3 innovative accelerated programs in pediatrics, family medicine, and orthopaedics that have yielded advantages to individual learners, including reduced educational debt, as well as to the health care system.
In an era of mandatory bundled payments for total joint replacement, accurate analysis of the cost of procedures is essential for orthopaedic surgeons and their institutions to maintain viable ...practices. The purpose of this study was to compare traditional accounting and time-driven activity-based costing (TDABC) methods for estimating the total costs of total hip and knee arthroplasty care cycles.
We calculated the overall costs of elective primary total hip and total knee replacement care cycles at our academic medical center using traditional and TDABC accounting methods. We compared the methods with respect to the overall costs of hip and knee replacement and the costs for each major cost category.
The traditional accounting method resulted in higher cost estimates. The total cost per hip replacement was $22,076 (2014 USD) using traditional accounting and was $12,957 using TDABC. The total cost per knee replacement was $29,488 using traditional accounting and was $16,981 using TDABC. With respect to cost categories, estimates using traditional accounting were greater for hip and knee replacement, respectively, by $3,432 and $5,486 for personnel, by $3,398 and $3,664 for space and equipment, and by $2,289 and $3,357 for indirect costs. Implants and consumables were derived from the actual hospital purchase price; accordingly, both methods produced equivalent results.
Substantial cost differences exist between accounting methods. The focus of TDABC only on resources used directly by the patient contrasts with the allocation of all operating costs, including all indirect costs and unused capacity, with traditional accounting. We expect that the true costs of hip and knee replacement care cycles are likely somewhere between estimates derived from traditional accounting methods and TDABC. TDABC offers patient-level granular cost information that better serves in the redesign of care pathways and may lead to more strategic resource-allocation decisions to optimize actual operating margins.
