RESUMO
BACKGROUND: The purpose of this was to investigate recent trends in procedure utilization, comorbidity profiles, hospital length of stay (LOS), 30-day outcomes, and risk factors for adverse events (AEs) among Black patients undergoing total hip arthroplasty (THA). METHODS: Using the American College of Surgeons National Surgery Quality Improvement Program, we retrospectively reviewed all Black patients who underwent elective, primary THA between 2011 and 2017. Mixed effects logistic regression analyses were performed to determine the trends in the study outcomes across each individual year. Multivariate logistic regression analyses were performed to identify independent risk factors for AEs. RESULTS: A total of 11,574 Black patients were analyzed. Over the study period, there was an increase by 109% in THA procedures performed in this racial group. During the same time, there were reductions in the prevalence of anemia, dyspnea, tobacco smoking, and osteonecrosis (p < 0.001). The rates of 30-day surgical complications, readmissions, reoperations, and mortality remained unchanged. Only the rate of medical complications demonstrated improvement, driven by a decrease in the incidence of postoperative myocardial infarction (p < 0.001). There was also a significant reduction in LOS > 2 days (68 to 37%, p < 0.001). Independent risk factors for AEs were body mass index > 35, American Society of Anesthesiologists score > 2, dependent functional status, diabetes, bleeding disorders, chronic kidney disease, and osteonecrosis as the surgical indication. CONCLUSION: Between 2011 and 2017, there were improving trends in procedure utilization, comorbidity profiles, and LOS among Black patients undergoing primary THA, but the overall rates of 30-day outcomes remained unchanged. We identified a number of risk factors that may help guide preoperative optimization and patient counseling to mitigate postoperative AEs.

BACKGROUND: Recent reports on the influence of gender on the outcomes of total joint arthroplasty were limited by either lack of longitudinal data or absent stratification by total hip arthroplasty (THA) or total knee arthroplasty (TKA). As a result, there remains a lack of clarity on this topic. METHODS: The American College of Surgeons National Surgical Quality Improvement Program was queried for all primary, elective THAs and TKAs performed between 2011 and 2017. Differences in demographics, comorbidity profiles, operative time, hospital length of stay (LOS), and 30-day outcomes were compared between male and female patients. Multivariate analyses were performed separately for THA and TKA. RESULTS: A total of 418,885 patients were analyzed; 59.1% were females. Compared with males, females were likely to be older, have a higher body mass index, identify as nonwhite, and require preoperative functional assistance (P < .001). Females had lower rates of diabetes, hypertension, anemia, and kidney disease but a higher rate of chronic steroid use (P < .001). They were also likely to have shorter operative times for both THA and TKA (P < .001). After controlling for the aforementioned differences, female gender was an independent risk factor for readmission, reoperation, and wound infection after THA (P < .001). In contrast, male sex was an independent risk factor for readmission, reoperation, and overall complications after TKA (P < .001). Regardless of the procedure, females were 64%-82% more likely to require an LOS >2 days than males. DISCUSSION: A variable effect of gender was observed on the post-total joint arthroplasty LOS and outcomes depending on the procedure type (THA or TKA). Differences attributed to gender should be accounted for in risk-stratification models. Future studies are also needed to elucidate the underlying causes of gender differences in joint arthroplasty.
RESUMO
By streamlining surgical care and eliminating postoperative hospitalization, the transition to ambulatory total knee arthroplasty (TKA) has the potential to improve efficiency and minimize the costs of care. However, practical, legal, and financial implications remain to be addressed. The Centers for Medicare and Medicaid Services has also yet to address concerns generated by the removal of TKA from the Inpatient-Only List and provide guidance on patient selection. Rolling out regulatory changes that impact high-volume procedures, such as TKA, in a short period of time and without appropriate feedback can only lead to further confusion. As surgeons, we are in a unique business model that requires us to constantly innovate to deliver high quality care, while also taking financial cuts as a result of our innovations.
RESUMO
Surgical techniques for the management of recalcitrant osteochondral lesions of the talus have improved; however, the poor healing potential of cartilage may impede long-term outcomes. Repair (microfracture) or replacement (osteochondral transplants) is the standard of care. Reparative strategies lead to production of fibrocartilage, which, compared with the native type II articular cartilage, has decreased mechanical and wear properties. The success of osteochondral transplants may be hindered by poor integration between grafts and host that results in peripheral cell death and cyst formation. These challenges have led to the investigation of biologic adjuvants to augment treatment. In vitro and in vivo models have demonstrated promise for cartilage regeneration by decreasing inflammatory damage and increasing the amount of type II articular cartilage. Further research is needed to investigate optimal formulations and time points of administration. In addition, clinical trials are needed to investigate the long-term effects of augmentation.

PURPOSE OF REVIEW: The use of biologics in orthopedics is becoming increasingly popular as an adjuvant in healing musculoskeletal injuries. Though many biologics involved in the management of foot and ankle injuries are used based on physician preference, reports of improved outcomes when combined with standard operative treatment has led to further clinical interest especially in foot and ankle trauma. RECENT FINDINGS: The most recent studies have shown benefits for biologic use in patients predisposed to poor bone and soft tissue healing. Biologics have shown benefit in treating soft tissue injuries such as Achilles ruptures as well as the complications of trauma such as non-unions and osteoarthritis. Biologics have shown some benefit in improving functional and pain scores, as well as reducing time to heal in foot and ankle traumatic injuries, with particular success shown with patients that have risk factors for poor healing. As the use of biologics continues to increase, there is a need for high-level studies to confirm early findings of lower level reports.
RESUMO
BACKGROUND: Bone bruises are frequently found on magnetic resonance imaging (MRI) after anterior cruciate ligament (ACL) injury and have been related to the force associated with the trauma. Yet, little is known about the bone bruise distribution pattern of skeletally immature (SI) patients, as the presence of an open physis may play a role in energy dissipation given its unique structure. PURPOSE: To describe and compare the location and distribution of tibial and femoral bone bruises, observed on MRI, between 2 groups of ACL-injured knees: the first group with an open physis and the second with a closed physis. Additionally, based on the bone bruise distribution pattern, the secondary aim of the study was to propose a new classification of bone bruise in SI patients. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: A retrospective review was conducted to identify all cases of primary ACL tears in patients ≤16 years old, with MRI within 6 weeks of injury between January 2012 and December 2016. Overall, 106 patients were identified: 53 with open physis (skeletally immature [SI] group) and 53 with closed physis as control (skeletally mature [SM] group). MRI scans were reviewed to assess for the presence and location of bone bruises. Longitudinal bone bruise distribution was described as epiphyseal and metaphyseal in both femur and tibia. The proposed classification for tibia and femur has 2 parts: the location of the bone bruise in the (I) lateral, (II) medial, or (III) medial and lateral parts of the bone; and if the bone bruise (a) does not or (b) does cross the physis. For the tibia, if the bone bruise is also present in the central portion, a letter C is added. RESULTS: The SI group had significantly fewer bone bruises cross the physis and extend into the metaphysis than did the SM group for both the tibia (25% vs 85%, respectively; P < .0001) and the femur (4% vs 42%; P < .0001). The most common patterns observed in the SI group were type IIICa in the tibia (medial/lateral and central, not extending into the metaphysis: 42%) and type Ia in the femur (lateral, not extending into the metaphysis: 59%). CONCLUSION: The data from this study shows that patients with an open physis at the occurrence of an acute ACL rupture have unique bone bruise patterns as compared with those with a closed physis. In the SI patients, the bone bruise pattern is significantly less frequently observed in the tibial and femoral metaphysis.

Even with the most accurate individualized, anatomic approach to anterior cruciate ligament (ACL) reconstruction, the potential for graft failure still exists, with reported retear rates as low as 5%, and even higher in female athletes or patients reconstructed with allograft. ACL graft healing is dependent on several factors, including anatomic placement, appropriate graft choice, proper technique, recovery time, and the biological environment of nature. If the double-bundle concept is followed and individualized for each patient's anatomic morphology, the ACL will biologically reform. The use of adult stem cells may help to contribute to the biological environment and aid in a faster healing time and quicker return to the preoperative state. There is a need for long-term studies and further research in human models to determine the optimal indication and environment for tissue healing with stem cell treatment.

Single-stage revision total knee arthroplasty has become an increasingly common treatment option for patients with failed knee prostheses. Periprosthetic knee infection is the leading and most devastating cause of revision total knee arthroplasty. Although periprosthetic knee infection has been extensively studied in the orthopaedic literature, the role of single-stage revision total knee arthroplasty for the treatment of periprosthetic knee infection warrants further research. As healthcare reform shifts from a volume-based to a value-based system, it is imperative that orthopaedic surgeons understand the procedural indications, risks, and benefits of single-stage revision total knee arthroplasty.

Two-stage revision total knee arthroplasty (TKA) is the standard of care for patients who require a revision procedure for the mangement of a late or chronic periprosthetic knee infection. A careful examination of two-stage revision TKA is warranted as the number of patients who require revision TKA in the United States continues to rise. Surgeons should understand the intricacies involved in two-stage revision TKA, including the indications, procedural variations, and current deliberations on two-stage revision TKA in the literature. Surgeons also should understand the alternative treatments for periprosthetic knee infections.

As the US population continues to grow in racial and ethnic diversity, we also continue to see healthcare disparities across racial lines. Considerable attention has been given to creating a physician workforce that better reflects the population served by healthcare professionals. To address the low numbers of women and underrepresented minorities in procedural based specialties, Nth Dimensions has sought to address and eliminate healthcare disparities through strategic pipeline initiatives. This is a retrospective observational cohort study of 118 medical students from 29 accredited US medical schools, who were awarded a position in the Nth Dimensions Summer Internship program between 2005 and 2012. Overall, 84 NDSI scholars applied and 81 matched into procedure-based specialties; therefore the overall retention rate was 75% and the overall match rate across the eight cohorts was 72.3%. Through intervention-based change, the authors hypothesize that greater numbers in the residency training cohorts can lead to a greater number of physicians with diverse backgrounds and perspectives. Ultimately, this will enhance quality of care for all patients and improve decision making process that influence healthcare systems. SUMMARY: Strategic pipeline programs increase successful recruit women and underrepresented minorities to apply and matriculate into procedure based residency programs. This is a retrospective observational cohort study of 118 medical students who completed the Nth Dimensions Summer Internship program between 2005 and 2012. Overall, 84 NDSI scholars applied and 81 matched into procedure-based specialties; therefore the overall retention rate was 75% and the overall match rate across the eight cohorts was 72.3%.

INTRODUCTION: Hip fractures are a common source of morbidity, mortality, and cost burden for elderly patients. We conducted a retrospective analysis of patients with hip fracture treated during the day or night at a rural level I academic trauma center and compared the postoperative outcomes and resource utilization for both groups. METHODS: Patients aged ≥55 years with hip fractures treated with definitive surgical fixation from April 2011 to April 2013 were included in this study. Patients who underwent surgery between 7 AM and 5 PM were included in the day cohort, while those who underwent surgery between 5 PM and 7 AM were included in the night cohort. A total of 441 patients met the study inclusion criteria. RESULTS: Comparison of the baseline characteristics of the two cohorts did not demonstrate significant variance. Although postoperative outcomes and resource utilization trends varied between the day and night cohort, only in-hospital cost was significantly higher in the day cohort (P = 0.04). Postoperative variables, including blood loss, [INCREMENT]hematocrit level, length of surgery, length of stay, time to surgery, in-hospital mortality, and 30-day readmission, did not vary significantly. CONCLUSION: Our study demonstrates a significantly higher cost associated with hip fracture procedures performed between 7 AM and 5 PM. In addition, perioperative blood loss and length of surgery were used as markers of physician fatigue; however, no statistically significant difference among these variables was found between hip fracture intervention performed during the day versus at night. LEVEL OF EVIDENCE: III, retrospective observational study.

BACKGROUND: Breast cancer prevalence is higher among female orthopaedic surgeons compared with U.S. women. The most common breast cancer site, the upper outer quadrant (UOQ), may not be adequately shielded from intraoperative radiation. Factors associated with higher breast radiation exposure (protective apron size and type, surgeon position, and C-arm position) have yet to be established. METHODS: An anthropomorphic torso phantom, simulating the female surgeon, was placed adjacent to a standard operating table. Dosimeters were placed over the UOQ and lower inner quadrant (LIQ) of the breast, bilaterally. Scatter radiation dose-equivalent rates were measured during continuous fluoroscopy to a pelvic phantom (simulating the patient). Four apron sizes (small, medium, large, and extra-large), 2 apron types (cross-back and vest), 2 surgeon positions (facing the table and 90° to the table), and 2 C-arm positions (anteroposterior and cross-table lateral projection) were tested. RESULTS: The median dose-equivalent rate of scatter radiation to the UOQ (0.40 mrem/hr) was higher than that to the LIQ of the breast (0.06 mrem/hr) across all testing, although this was not statistically significant (p = 0.05). The cross-back aprons provided higher protection to the LIQ compared with the vests (p < 0.05). Lead protection in sizes that were too small or too large for the torso had higher breast radiation dose-equivalent rates. C-arm cross-table lateral projection was associated with higher breast radiation exposure (0.98 mrem/hr) compared with anteroposterior projection (0.13 mrem/hr) (p < 0.001). CONCLUSIONS: Breast radiation exposure is higher in a C-arm lateral projection compared with an anteroposterior projection. Higher dose-equivalent rates were observed for the UOQ compared with the LIQ of the breast and for aprons that were too small or too large, although these differences did not reach significance. Factors that may reduce radiation exposure include lead protection of appropriate size and distancing the axilla from the patient and x-ray tube. CLINICAL RELEVANCE: Increased breast cancer prevalence has been reported for female orthopaedic surgeons. The UOQ of the breast may be at risk for intraoperative radiation exposure. Methods of reducing exposure are warranted.

The US health care system has been fragmented for more than 40 years; this model created a need for modification. Sociopoliticomedical system-related factors led to the Affordable Care Act (ACA) and a restructuring of health care provision/delivery. The ACA increases access to high-quality "affordable care" under cost-effective measures. This article provides a comprehensive review of health reform and the motivating factors that drive policy to empower arthroplasty providers to effectively advocate for the field of orthopedics as a whole, and the patients served.

As health care reforms continue to improve quality of care, significant emphasis will be placed on evaluation of orthopedic patient outcomes. Total joint arthroplasty (TJA) has a proven track record of enhancing patient quality of life and are easily replicable. The outcomes of these procedures serve as a measure of health care initiative success. Specifically, length of stay, will be targeted as a marker of quality of surgical care delivered to TJA patients. Within this review, we will discuss preoperative and postoperative methods by which orthopedic surgeons may enhance TJA outcomes and effectively reduce length of stay.

Surgical site infection in total joint arthroplasty is a challenging complication that warrants discussion with regard to prevention and management. Limiting postoperative infection rate is a paramount quest in the orthopedic community. Several preoperative risk factors have been identified in orthopedic literature with regards to likelihood of developing postoperative infection. This article evaluates several factors that predispose total joint arthroplasty patients to infection. Methods of patient surgical preparation designed to decrease postoperative infection, decreasing intraoperative traffic during procedural settings, and elaborate intraoperative prophylactic advancements are assessed. Approaches to decrease postoperative infection by discussing means of lowering rates of postoperative transfusion, wound drainage, and hematoma formation are analyzed.

Hospital readmission is a focus of quality measures used by the Center for Medicare and Medicaid (CMS) to evaluate quality of care. Policy changes provide incentives and enforce penalties to decrease 30-day hospital readmissions. CMS implemented the Readmission Penalty Program. Readmission rates are being used to determine reimbursement rates for physicians. The need for readmission is deemed an indication for inadequate quality of care subjected to financial penalties. This reviews identifies risk factors that have been significantly associated with higher readmission rates, addresses approaches to minimize 30-day readmission, and discusses the potential future direction within this area as regulations evolve.

Patient-centered care (PCC) is gaining considerable momentum among health care professionals and policy-making authorities. The need for PCC stems from the innumerable benefits of adopting such a system. The practice of PCC in orthopedic surgery in general, and in total joint replacement in particular, is still in its youth. However, present literature already establishes the need for applying PCC in total joint replacement. Extensive research and effort should be invested to better grasp and define the dimensions of PCC as they relate to total joint replacement.

Under the Patient Protection and Affordable Care Act (ACA), the Centers for Medicare and Medicaid Services' Innovation was chartered to develop new models of health care delivery. The changes meant a drastic need to restructure the health care system. To minimize costs and optimize quality, new laws encourage continuity in health care delivery within an integrated system. Affordable care organizations provided a model of high-quality care while reducing costs. Bundled payments can have a substantial effect on the national expenditures. This article examines new developments in bundle payments, affordable care organizations, and gainsharing agreements as they pertain to arthroplasty.

Osteolysis is a process mounted by the host immune system that relies on several variables, including patient-related factors, type of insert material, modes of wear, and implant design. Imaging techniques such as radiography, computed tomography (CT) scans, magnetic resonance imaging (MRI), and tomosynthesis aid in diagnosing osteolysis. Surgical options for the treatment of osteolysis include the insertion of bone grafts, bone cement, and prosthetic augmentation. Although no approved pharmacological therapies for the specific treatment of osteolysis exist, the use of bisphosphonates and statins decreases the risk of osteolysis.
