Unique to this registry is the high use of cementless femoral stems in patients 65 years and older. We identified 266,040 primary cementless THAs during the study period in patients with a diagnosis of osteoarthritis and surgeries linked to supplemental Centers for Medicare and Medicaid data where available. Patient demographics, procedure dates, and reoperation for periprosthetic femur fracture with revision or open reduction and internal fixation were recorded. The main analysis was performed comparing the Kheir and Chen classification: 42% (112,231 of 266,040) were single-wedge, 22% (57,758 of 266,040) were double-wedge, and 24% (62,983 of 266,040) were gradual taper/metadiaphyseal-filling cementless femoral components, which yielded a total of 232,972 primary cementless THAs.

Although these methods are variably effective, they are associated with morbidity (pain and limp) and potential complications. Microwave ablation is a less-invasive opportunity to halt growth by selectively destroying the growth plate via thermal energy to treat LLD in children.</p><p><strong>Questions/purposes: </strong>In this proof-of-concept study using an in vivo pig model, we asked: (1) What is the durability of response 2 to 4 months after microwave ablation of the tibial growth plate as measured by length and angulation of the tibia via a CT scan? (2) Was articular cartilage maintained as measured by standard histologic staining for articular cartilage viability?</p><p><strong>Methods: </strong>To develop an in vivo protocol for microwave ablation, we placed microwave antennas adjacent to the proximal tibia growth plate in the cadaveric hindlimbs of 18 3-month-old pigs. To determine the suitable time, we varied ablation from 90 to 270 seconds at 65-W power settings. After sectioning the tibia, we visually assessed for discoloration (implying growth plate destruction) that included the central growth plate but did not encroach into the epiphysis in a manner that could disrupt the articular surface. Using this information, we then performed microwave ablation on three live female pigs (3.5 to 4 months old) to evaluate physiologic changes and durability of response. A postprocedure MRI was performed to ensure the intervention led to spatial growth plate alterations similar to that seen in cadavers. This was followed by serial CT, which was used to assess the potential effect on local bone and growth until the animals were euthanized 2 to 4 months after the procedure. We analyzed LLD, angular deformity, and bony deformity using CT scans of both tibias. The visibility of articular cartilage was compared with that of the contralateral tibia via standard histologic staining, and growth rates of the proximal tibial growth plate were compared via fluorochrome labeling.</p><p><strong>Results: </strong>Eighteen cadaveric specimens showed ablation zones across the growth plate without visual damage to the articular surface. The three live pigs did not exhibit changes in gait or require notable pain medication after the procedure. Each animal demonstrated growth plate destruction, expected limb shortening (0.8, 1.2, and 1.5 cm), and bony cavitation around the growth plate. Slight valgus bone angulation (4º, 5º, and 12º) compared with the control tibia was noted.

Growing recognition of this deficit and the benefits of a diverse healthcare workforce has motivated policy changes to improve diversity. To measure progress with these efforts, it is important to understand the existing representation of sexual and gender minorities among orthopaedic professionals.</p><p><strong>Questions/purposes: </strong>(1) What proportion of American Academy of Orthopaedic Surgeons (AAOS) members reported their identity as a sexual or gender minority? (2) What demographic factors are associated with the self-reporting of one's sexual orientation and gender identity?</p><p><strong>Methods: </strong>The AAOS published the updated membership questionnaire in January 2022 to collect information from new and existing society members regarding age and race or ethnicity and newly added categories of gender identity, sexual orientation, and pronouns. The questionnaire was updated with input from a committee of orthopaedic surgeons and researchers to ensure face validity. The AAOS provided a deidentified dataset that included the variables of interest: membership type, gender identity, sexual orientation, pronouns, age, race, and ethnicity. Of 35,427 active AAOS members, 47% (16,652) updated their membership questionnaire. To answer our first study question, we calculated the prevalence of participants who self-reported as lesbian, gay, bisexual, transgender, queer, or another sexual or gender minority identity (LGBTQ+) and other demographic characteristics of the 16,652 respondents. Categorical demographic data are described using frequencies and proportions. Median and IQR were used to describe the central tendency and variability. To answer our second study question, we conducted a stratified analysis to compare demographic characteristics between those who self-reported LGBTQ+ identity and those who did not. Visual methods (quantile-quantile plots) and statistical tests (Kolmogorov-Smirnov and Shapiro Wilk) confirmed that the age of AAOS member was not normally distributed. Therefore, a Kruskal Wallis test was used to determine the statistical associations between age and self-reported LGBTQ+ status. Chi-square tests were used to determine bivariate statistical associations between categorical demographic characteristics and self-reported LGBTQ+ status. A multivariable logistic regression model was developed to identify the independent demographic characteristics associated with respondents who self-reported LGBTQ+ identity. Further stratified analyses were not conducted to protect the anonymity of AAOS members.
