In , Nutescu et al. found that pediatric patients with public insurance and/or those from racially minoritized groups were more likely to experience delays in care for ACL reconstructive surgery at each step of the preoperative timeline, even after confirmed injury.

"Although most of these disparities originate before orthopaedic evaluation, surgeons may consider strengthening relationships with local primary care, emergency medicine, and urgent care clinicians as well as other community stakeholders to facilitate communication and referrals when needed," the authors write.

"Individual physicians may not be able to change the healthcare system overnight, but we can exert meaningful influence within our own practices and institutions," writes John D. Polousky in a commentary. "By educating colleagues, leveraging existing resources, and maintaining open channels of communication, each of us can incrementally improve care delivery."

In , Mao et al. found that only 7% of orthopaedic trials in the ClinicalTrials database were led by women surgeons, and when subspecialty demographics were factored in, women primary investigators (P*s) were proportionally underrepresented in all but two: hip & knee (where they were proportionally represented) and spine (where they were overrepresented).

"As the underrepresentation of women P*s was clustered in specific subspecialties, interventions in these fields are especially warranted, (and our findings) provide a valuable baseline against which the impact of future initiatives can be evaluated," the authors write.

"The feeling that each personal choice—like starting a family—can endanger one’s professional standing leads to discomfort and a feeling of instability (that) can permeate into other areas, such as research productivity, promotions, or clinical trial leadership," writes Amanda Mener in a commentary that is free to read all month 🚩. "(So) while, at first glance, (a lack of) parental leave policies may not seem directly related to (gender) differences in terms of publication output in academic orthopaedic surgery, the dearth of women faculty, or the unequal representation in clinical trial leadership... all of these issues are interwoven."

In a retrospective study in , Maxwell et al. found that the two most commonly used metrics to measure social determinants of health in pediatric research—the Child Opportunity Index (COI) and Area Deprivation Index (ADI)—had a similar magnitude of association with undergoing ACL reconstruction beyond 60 and 90 days post-injury, but only the COI was associated with delays beyond 180 days.

"This study offers an important methodological blueprint for future disparities research within pediatric orthopaedics," writes Gregory J. Kirchner in a commentary. "Researchers should justify the selection of a particular measure of socioeconomic deprivation as it pertains to their study question (and) editors of orthopaedic journals need to request justification when it is absent."

"As the initial step in health equity research is to identify a disparity, utilization of the most appropriate neighborhood-level metrics will ensure that these are detected," the authors write. "For example, based on the results of this study, we used COI scores as one of several criteria to identify the most appropriate neighborhoods to engage with for community-based research on pediatric ACL disparities."

🚩Free to read through September 13: Using the Area Deprivation Index (ADI) as a surrogate for various social determinants of health (SDOH), Lam et al. found modest but consistent differences in perioperative communications with patients undergoing THA or TKA, with those from the most deprived areas requiring 17% more staff-initiated touchpoints.

"Our findings may not necessarily change clinical decision-making, but (they are) operationally relevant to the typical orthopaedic practice," the authors write in . "Our study can help practices anticipate communication demands that improve efficiency and resource allocation."

"What does this look like in real life?" writes Wakenda K. Tyler in a commentary. "Lam et al. identified two very important pieces of information that could help guide future practice models: Those in the low ADI cohort do not need as much direct communication and might actually benefit more from online video or educational material they can use on their own, whereas the high ADI group would likely benefit from direct contact education or more intentional outreach by the practice staff."

"We have reached an inflection point in the research that addresses the diversity within our profession and the disparities that many of our patients face," write Drs. Templeton & Hogan in their introduction to the 2026 Diversity & Disparities Symposium in . "The 'why' has been discussed for decades, and we believe it has been sufficiently answered. The 'what' has been clarified as well, although the answers will continue to change over time. Now, it’s time for us to work on the 'how'—how can we improve the status quo, preferably before 200 years go by?"

🚩Free to read all month: In this issue's spotlight article, Son et al. applied international benchmarking standards to 45 TKA implant systems in a large US-based registry and found that most performed consistently—whether at inferior, adequate, or superior levels—at each timepoint they were evaluated at (ranging from 2 to 15 years).

"These findings support prioritizing implant systems that meet benchmark standards for primary TKA and reevaluating routine use of implants that fail to achieve benchmarks when alternatives with reliable mid- and long-term performance are available," the authors write.

"Some clinicians believe that registry-based research is somehow inferior to randomized clinical trials. This is a misconception; these two study designs complement one another," writes Seth Leopold MD in the Editor's Spotlight on this article. "This study (shows) how registries (can) do more to inform decision-making outside of arthroplasty—trauma registries, sports medicine registries, for example—and what kind of progress the world’s registries are making at capturing PROMs."

🚩Free to read all month: "A common trope we hear is that all of the leading general-interest orthopaedic surgery journals, including , really are little more than arthroplasty journals in sheep’s clothing," write the senior editors in this month's . "We would like to do what we can to dispel that myth, at least as it applies to our journal, to make our best case for what a 'CORR paper' really is, and to explain why sending your next great paper here—regardless of your subspecialty—would be a get-ahead choice."
