Introduction: Initiation of Pavlik harness treatment for developmental dysplasia of the hip (DDH) by 6 to 7 weeks of age predicts a higher rate of success. Child Opportunity Index (COI) 2.0 is a single metric designed to measure resources and conditions affecting children's healthy development. This study investigates COI in relation to the timing of DDH diagnosis.

Methods: This is a retrospective cohort study on patients younger than 4 years diagnosed with DDH between 2016 and 2023, treated with a Pavlik harness, rigid hip abduction orthosis, and/or surgery. Demographic and clinical data were recorded, including date of first diagnostic imaging. Patients with syndromes, congenital anomalies, or neuromuscular disorders and those referred with an unknown date of first diagnostic imaging were excluded. A subgroup analysis of patients diagnosed at ≤6 weeks ("early") and >6 weeks ("late") was conducted. Statewide COI scores (total, three domains) and categorical quintile scores (very low, low, moderate, high, and very high) were recorded.

Results: A total of 115 patients were included: 90 female infants (78%), with a median age of 32 days at diagnostic imaging. No notable difference was observed between median age at diagnosis for study patients in low or very low quintiles and those in moderate, high, or very high quintiles for COI total or domains. "Early" and "late" diagnosis subgroups did not differ markedly by COI total or domains, nor insurance type, race, or ethnicity. Subgroups differed markedly by race and insurance status.

Discussion: In an urban children's hospital, COI did not differ markedly between patients diagnosed with DDH by ≤6 weeks and >6 weeks. This is the first study to pose this question on DDH in a population with predominantly low/very low COI scores and public insurance, which may lead to unexpected results. Replicating the study in a different setting could yield different results.

The purpose of this review was to evaluate the effect of adverse events (AEs) on orthopaedic surgeons, illustrate common ways orthopaedic surgeons deal with AEs, and describe solutions to reduce the negative effect of AEs and prevent them from recurring. AEs are common in orthopaedic surgery and increase the risk of depression, anxiety, and suicide. Orthopaedic surgeons may experience negative effects after AEs even when they are not at fault. AEs are linked to moral injury, second victim syndrome, burnout, and disruptive physician behaviors. Many surgeons deal with AEs in isolation out of fear of a negative effect on their professional reputation, potentially leading to increased psychological distress and unhealthy coping mechanisms. Healthy ways to address AEs and improve the well-being of surgeons include destigmatizing psychological stress after AEs and creating a culture of receptivity and peer support.

Venous thromboembolism (VTE), comprising pulmonary embolism and deep vein thrombosis, is one of the most common complications after knee arthroscopy. Sequelae of VTE include VTE recurrence, postthrombotic syndrome, and potential for loss of limb or life. Given the increasing volume of knee arthroscopy procedures worldwide and the considerable morbidity and mortality associated with VTE, it is important to prevent, diagnose, and treat VTEs efficiently and effectively. Risk factors such as history of VTE, family history of VTE, genetic coagulopathy, oral contraceptive use, cancer history, and old age increase the risk of postoperative VTE and warrant consideration of prophylaxis. Diagnosis and treatment should be initiated rapidly in the setting of concerning symptoms and positive imaging diagnosis, respectively. The purpose of this review was to provide a framework to individualized VTE risk, weigh prophylaxis options, expedite diagnostic pathways, and implement outpatient treatment algorithms.

Introduction: Next-generation DNA sequencing (NGS) technologies have increased the sensitivity for detecting the bacterial presence and have been used in other areas of orthopaedics to better understand the native microbiome of various joints. This study uses NGS to determine whether (1) a unique microbiome exists in human ankle tissues, (2) if components of the ankle microbiome affect patient outcomes, and (3) whether microbes found on the skin are a normal part of the ankle microbiome.

Methods: A prospective study recruited 32 patients undergoing total ankle arthroplasty (n = 23) or ankle arthrodesis (n = 9) via direct anterior approach between November 2020 and October 2021. During surgery, five layers of the ankle were swabbed: skin (n = 32), retinaculum (n = 31), tibialis anterior tendon (n = 31), joint capsule (n = 31), and distal tibia (n = 32). These swabs (N = 157) were sent to MicroGen Diagnostics (Lubbock) for NGS. Demographics, medical comorbidities, surgical indication, postoperative complications, readmission, and revision surgery rates were collected from patient records.

Results: The mean age was 60.7 (range, 19 to 85) years, and the mean follow-up duration was 10.2 (range, 4.8 to 20.6) months. Of 157 swabs sent for NGS, 19 (12.1%) indicated that bacteria were present (positive), whereas the remaining 138 (87.9%) had no bacteria present (negative). The most common organisms were Cutibacterium acnes in eight ankles (25.0%) and Staphylococcus epidermidis in two ankles (6.25%). Most bacteria were found in the retinaculum (29.6%). Complications, nonunions, infections, 90-day readmission, and revision surgery rates did not differ by NGS profile.

Discussion: This study found that C acnes and S epidermidis were the most common bacteria in the ankle microbiome, with C acnes being present in 25% of ankles. Complication rates did not differ between patients with or without positive bacterial DNA remnants. Thus, we concluded that a unique ankle microbiome is present in some patients, which is unique from that of the skin of the ankle.

Level of evidence: Level II, Prospective cohort study.

Introduction: There has been increasing interest in remote measures of patients' health, both in the clinical and research settings. This study sought to evaluate correlations between patient-reported and clinician-measured (CM) shoulder range of motion (ROM).

Methods: ROM measures including elevation, abduction, and internal rotation were recorded by a patient-reported picture-based survey and clinician measurement during each patient visit. A total of 13,842 visits over a 16-year period met inclusion criteria. Spearman correlation was performed to determine the correlation between patient-reported and CM elevation, abduction, and internal rotation. A subgroup analysis was conducted to evaluate motion in patients who underwent arthroplasty and arthroscopy.

Results: Patients were 52.4% male with a median age of 67 years (range, 18 to 96). PR and CM shoulder ROM were gathered at 13,842 patient visits. Strong correlations between PR and CM elevation (r = 0.70) and internal rotation (r = 0.66) were found, as well as a moderate correlation between PR and CM abduction (r = 0.59). Strong correlations were found between all three PR and CM measures of motion in the arthroplasty subgroup (elevation r = 0.74, abduction r = 0.63, and internal rotation r = 0.64).

Conclusions: There is a strong correlation between patient-reported and CM shoulder elevation and internal rotation, as well as a moderate correlation between PR and CM abduction. This allows for a method of assessing patient motion without requiring an in-person visit.

Level of evidence: Level III Retrospective Cohort Study.

Background: There is mounting evidence that, among musculoskeletal patients, variation in capability has more notable associations with variations in mental and social health factors than with variation in pathophysiology severity. This study sought factors that could limit the integration of this evidence into more comprehensive care models.

Methods: In two scenario-based experiments, surgeon participants in an international collaborative, the Science of Variation Group, reviewed scenarios of (a) nontraumatic (83 participants) and (b) trauma-related (130 participants) pathophysiologies for which tests and treatments were discretionary. The following demographic, mental, and social health elements were varied randomly: sex, age, race/ethnicity, mindsets, social health aspects, and specific pathophysiologies. For each scenario, participants rated their likelihood to offer surgery (continuous) and their sense of presence of an opportunity to address better mental or social health in treatment (yes or no). Factors associated with each rating were sought in multivariable analysis.

Results: Greater likelihood to offer discretionary surgery for nontraumatic pathophysiologies was associated with greater pathophysiology severity, trapeziometacarpal arthritis, and greater distress and unhelpful thoughts regarding symptoms. Lateral elbow enthesopathy was associated with a lower likelihood. For trauma-related pathophysiologies, an ankle fracture with slight articular subluxation was associated with greater likelihood to offer surgery, and several other trauma-related pathophysiologies were associated with a lower likelihood. For both nontraumatic and trauma-related pathophysiologies, surgeons noticed unhelpful thinking, distress, and social issues as reasons to consider addressing mental and social health in treatment, relatively independent of pathophysiology.

Conclusion: Surgeons seem to recognize opportunities to address mental and social needs but ultimately base their decision to offer discretionary surgery on pathophysiological factors.

Clinical relevance: Comprehensive, whole-person care for musculoskeletal illness might be supported by strategies for ensuring that aspects of stress and distress that contribute to greater symptom intensity are not misinterpreted as a reflection of greater pathophysiology severity.

Pickleball is one of the fastest growing sports in the United States with millions of players nationwide. It is a relatively appealing sport because of its ease of access, low impact, and highly social atmosphere, allowing players of all ages to participate. As the number of players continues its dramatic increase, player injuries are certain to increase in turn. There is little to no orthopaedic research on pickleball-related injuries and a paucity of data regarding treatment and prevention strategies. This summary was designed to familiarize orthopaedic surgeons with the basics of the sport and highlight potential pickleball-related injuries they may encounter in practice.

Introduction: The quality and volume of information on orthopaedic surgery residency program websites are helpful for informed decision making of prospective applicants. The purpose of this study was to evaluate the content on orthopaedic surgery residency program websites and identify areas for improvement.

Methods: In November 2023, 203 orthopaedic surgery residency programs were reviewed using the Association of American Medical Colleges Residency Explorer tool. Fourteen nonfunctional websites were excluded, leaving n = 189. Websites were assessed for 11 variables: resources for assisting resident research (eg, biomechanics laboratory, research assistant, and advisors), residents' past institutional affiliations, current resident profiles (including hometown and interests), alumni data, fellowship matches, American Board of Orthopedic Surgery I/II pass rates, Alpha Omega Alpha Society affiliation, target United States Medical Licensing Examination/ Comprehensive Osteopathic Medical Learning Exam Step 2 scores, educational activities (journal club, grand rounds, didactics), evaluation methods, and mentorship.

Results: Website variables differed markedly among identified program types, which included community programs, university programs (UPs), and affiliated programs (APs). Disparities were noted in the disclosure of residents' previous institutions ( P = 0.001), the availability of alumni names ( P = 0.001), research resources ( P = 0.001), academic activities ( P = 0.007), assigned mentorship programs ( P = 0.006), and fellowship match information ( P = 0.027). Notably, community programs shared statistically significantly less information in these areas compared with UPs and APs ( P = 0.001). While there was a proportionate sharing of information between UPs and APs, UPs exhibited a slightly higher overall percentage of websites sharing more detailed information.

Conclusion: The quality and comprehensiveness of information on orthopaedic surgery residency program websites vary markedly. Most of the orthopaedic surgery residency programs provided information on residents' past institutions and academic activities. However, very few provided information on designated mentorship programs or objective measures such as target Step 2 examination scores and ABOS pass rates. Improving the quality of information available on program websites will enhance transparency and consistency, enabling prospective applicants to make more informed decisions about where to apply and interview.

Introduction: Orthopaedic surgery has consistently been one of the most competitive specialties in the US residency selection process. This is due in part to the steady upward trend in average applications received per program and average applications submitted per applicant, which is of growing concern. With the implementation of the Preference Signaling Program, the total number of applications has now dropped for the first time in many years, indicating signaling may improve the application process. The hypothesis is that signaling has led to a decrease in applications sent by applicants and a decrease in applications received by programs.

Methods: A 7-question survey regarding their interview and match statistics was sent to orthopaedic surgery residency programs that participated in the Electronic Residency Application Service during the 2023-2024 application cycle. A response from the program director/administrator was then recorded.

Results: Our program search yielded 159 programs with 106 respondents (66.7%). 82 programs (78.8%) solely interviewed applicants who signaled their program. 92.7% of current interns signaled the program where they matched, and 88 programs (84.6%) matched only applicants who signaled. 95 programs (89.6%) revealed that implementing signaling has improved the application process.

Conclusion: Most of the programs only interviewed applicants who also signaled, and nearly all matched orthopaedic surgery applicants from the 2022-2023 cycle signaled their matching program. Orthopaedic surgery applicants should consider only applying to 30 programs and using all 30 available signals. Applicants should also be more confident knowing that beyond the 30 signals they use, there is limited support to say that they will receive an interview outside of these 30 applications. Orthopaedic surgery programs will also now have the ability to allocate more time to applicants most interested in their program, given the reduction of applications.

Increased participation in youth sports has led to more knee injuries necessitating surgical intervention. Among the youngest athletes, such procedures typically involve physeal-respecting techniques for anterior cruciate ligament reconstruction, medial patellofemoral ligament reconstruction for patellar instability, osteochondritis dissecans fixation, and implant-mediated guided growth procedures. In each case, the choice of appropriate intervention is critically dependent on a patient's skeletal maturity. Compared with chronologic age, skeletal age accounts for individual maturation and is the benchmark for determination of development in orthopaedics. This is historically assessed using the Greulich and Pyle method, in which bone age is determined through comparison of a patient's hand radiograph with the closest standard radiograph from an atlas of American children from the early 1900s. In the setting of knee pathology, obtaining additional imaging requires further radiation and time. Several bone age determination methods exist incorporating radiographic characteristics of the distal femur, proximal tibia, and/or proximal fibula. This study therefore sought to review available methods for determination of skeletal age when planning surgeries about the knee using readily available, routine knee imaging. The review focuses on both radiograph and MRI-based skeletal maturity staging systems that surgeons may use to guide appropriate treatment while describing the strengths and weaknesses of each method.
