Abstract As artificial intelligence (AI) Large Language Models (LLM) like ChatGPT become more common in healthcare, patients increasingly use them to find medical information. While ChatGPT may support health literacy, its readability and accuracy compared to established resources remain unclear. The purpose of this study is to evaluate ChatGPT-4 responses on femoroacetabular impingement (FAI) and its surgical management compared to AAOS OrthoInfo content. We hypothesize that ChatGPT may deliver medically accurate information, but its readability may fall short when compared to OrthoInfo. Nine questions based on the OrthoInfo FAI page were submitted to ChatGPT-4, with and without a readability prompt. Topics included anatomy, pathology, cause, symptoms, workup, imaging, treatment, role of hip arthroscopy, and outcomes. Readability was assessed using validated indices. Accuracy was independently rated using a 4-point scale. Statistical comparisons were made using t-tests and ANOVA (P < 0.01 threshold). OrthoInfo content had a mean reading grade level of 8.0 and a Flesch Reading Ease score of 60.7. Unprompted ChatGPT responses were significantly less readable (grade level 16.2; Flesch score 21.7; P < 0.001). Prompting for readability improved ChatGPT outputs (grade level 10.6; Flesch score 58.2), making them comparable to OrthoInfo (P < 0.09). Accuracy was high across all sources, though OrthoInfo's response on FAI causes scored slightly lower (3.5 versus 4.0; P < 0.46). ChatGPT provides accurate information on FAI. However, without prompting, its complexity may hinder patient understanding. Prompting for readability enables ChatGPT to match established resources like OrthoInfo. Tailored prompting is key to using LLM effectively in patient education and promoting health literacy.

Background: Distal radius fractures involving the physis are among the most common upper extremity injuries in children and adolescents. Unlike transitional fractures of the distal tibia, known as Tillaux and triplane fractures, transitional fractures of the distal radius have not been well characterized. This study aims to evaluate Salter-Harris III and IV fractures of the distal radius in the pediatric transitional age population to determine if a characteristic fracture pattern exists analogous to the distal tibia. We hypothesized that pediatric transitional fractures of the distal radius would follow a pattern that would ultimately dictate treatment and predict outcomes. Methods: A retrospective chart review of pediatric patients with transitional fractures of the distal radius at a single institution was performed. Salter-Harris III and IV fractures of the distal radius with CT imaging were included. Two independent reviewers determined the metaphyseal fracture plane and the major intra-articular epiphyseal fracture fragments. Descriptive statistical analysis was performed. Results: Thirty patients who met inclusion criteria made the study cohort. There were 5 Salter-Harris III fractures and 25 Salter-Harris IV fractures. Mean age at the time of injury was 15±1.5 years. The metaphyseal fracture demonstrated a coronal fracture plane in all cases, and 20% had a sagittal plane component. The major epiphyseal fracture fragments were identified as dorsal ulnar corner in 70%, radial column in 43%, volar rim in 30%, and dorsal wall in 17%. Patients were treated with open reduction and internal fixation (N=12, 40%), closed reduction and percutaneous pinning (N=4, 13%), or cast immobilization (N=14, 47%). Most patients (N=24, 80%) did not demonstrate a growth disturbance after treatment. Angular deformity, however, was significantly higher in patients with a primary dorsal ulnar corner epiphyseal fragment (N=4, 19% vs. N=0%, P =0.03). Conclusion: Transitional fractures of the distal radius occurred on average at age 15. The injuries demonstrated a consistent pattern, with a coronal fracture plane in the metaphysis and a dorsal ulnar corner fragment in most epiphyses. The dorsal physis may be the strongest portion of the distal radius at the time of injury, though mechanism of injury may impact patterns as well. Level of Evidence: Level III.

Objectives: Ice hockey is a physically demanding sport, with young athletes prone to anterior cruciate ligament (ACL) injuries. Currently, there is a paucity of data examining the results of ACL reconstruction (ACLR) in competitive hockey players. The purpose of this study was to assess return to hockey (RTH) and reoperation rates following ACLR for ACL injuries in a cohort of competitive hockey players. Methods: All competitive ice hockey players (including, youth, high school, juniors, collegiate, or professional) with a history of ACL injury and subsequent ACLR at a single academic institution between 2000 and 2022 were identified. Exclusion criteria included ACL injuries that did not occur during hockey, history of ACLR prior to hockey injury, and recreational hockey players. Graft failure was defined as a retear (as determined via clinical or advanced imaging evaluation) and/or revision ACLR. Results: Ultimately, 50 knees in 44 hockey players were included at a mean (± standard deviation) follow-up time of 7.0 years ± 5.4 years (Table 1). The mean age at the time of index surgery was 18.9 years ± 3.0 years, with 38 males (76%), and the distribution of bone-patellar tendon-bone (BPTB) and hamstring tendon (HT) autografts was 40 (80%) and 10 (20%), respectively. RTH occurred in 66% of hockey players at a mean of 10.2 months ± 6.2 months. Graft failure occurred in 9 knees (18%) at a mean of 5.9 years ± 5.8 years after the index ACLR. All patients who sustained a retear underwent reoperation. Kaplan-Meier survivorship free from surgical failure of the entire cohort was 94% at 1 year, 88% at 5 years, 74% at 10 years, and 67% at 15 years (Figure 1A). BPTB autograft demonstrated a lower failure rate compared with HT autograft (13% vs 40%; P = 0.041) and was associated with better survival compared with HT autograft up to 15 years after the index ACLR (80% vs 39%; P = 0.047; Figure 1B). Conclusions: ACL injury remains a concern for competitive hockey players after ACLR. Return to competitive ice hockey was observed in 66% of athletes after ACLR, with 18% of hockey players experiencing graft failure and undergoing subsequent reoperation. BPTB autograft was associated with better survival than HT autograft.

Background There is substantial corroborating evidence that orthopaedic surgery has historically been the least diverse of all medical and surgical specialties in terms of race, ethnicity, and sex. 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. Questions/purposes (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? Methods 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. An alpha level of 5% was established a priori to define statistical significance. Results Overall, 3% (109 of 3679) and fewer than 1% (3 of 16,182) of the AAOS members (surgeons, clinicians, allied healthcare providers, and researchers) who updated their membership profiles reported identifying as a sexual (lesbian, gay, bisexual, queer) or gender minority (nonbinary or transgender), respectively. No individual self-identified as transgender. Five percent (33 of 603) of women and 3% (80 of 3042) of men self-identified as a sexual minority (such as lesbian, gay, bisexual, or queer). AAOS members who self-identified as LGBTQ+ were younger (OR 0.99 [95% confidence interval (CI) 0.98 to 0.99]; p < 0.001), less likely to self-identify as women (OR 0.86 [95% CI 0.767 to 0.954]; p < 0.001), less likely to be underrepresented in medicine (OR 0.49 [95% CI 0.405 to 0.599]; p < 0.001), and less likely to be an emeritus or honorary member (OR 0.75 [95% CI 0.641 to 0.883]; p < 0.003). Conclusion The proportion of self-reported LGBTQ+ AAOS members is lower than the 7% of the general US population. The greater proportion of younger AAOS members reporting this information suggests progress in the pursuit of a more-diverse field. Clinical Relevance The study findings support standardized collection of sexual orientation and gender identity data to better identify and address diversity gaps. As orthopaedic surgery continues to transform to reflect the diversity of musculoskeletal patients, all orthopaedic professionals (surgeons, clinicians, allied healthcare providers, and researchers), regardless of their identities, are essential in the mission to provide equitable and informed orthopaedic care. Sexual and gender minority individuals may serve as important mentors to the next generations of orthopaedic professionals; individuals from nonminority groups should serve as important allies in achieving this goal.

Purpose: This study aims to report the epidemiology of patellar sleeve injuries, describe diagnostic findings and treatment, and assess functional outcomes following different treatments. Methods: A medical database was queried from 1990 to 2016 to identify patients ≤18 years presenting to a single pediatric institution with a patellar sleeve injury. Patients with significant comorbidities or previously operatively treated for ipsilateral knee injuries were excluded. Standard demographic data, mechanism of injury, skeletal maturity, injury-related radiographic parameters, along with treatment paradigms, post-treatment clinical and radiographic findings, and patient-reported outcomes were collected. Results: A total of 90 patients, mean age of 10.7 years (range: 7–17) was included, of which 69 (77%) were male. Seventy-three percent of all injuries occurred while playing sports (particularly football/basketball/soccer), with “direct blow” or “landing” being the most prevalent mechanisms of injury. Twenty-six (29%) underwent operative treatment, with transosseous suture fixation being the most popular surgical technique (73%). Of the 64 (71%) non-operatively treated patients, 18 (39%) were placed in a hinged knee brace locked in extension with the remainder split between casting and standard knee immobilizer. Compared to the non-operative cohort, a higher percentage of the operative group had a pre-treatment extensor lag (p < 0.001) and greater fragment displacement (p < 0.001) with patella alta (p < 0.001) on imaging. There was no difference in outcome scores (Pedi-IKDC/Lysholm) or patella alta on radiographs between groups. Post-treatment surveys indicated no difference in residual pain or ability to return to sport. Conclusion: This large case series provides valuable epidemiologic, clinical, and radiographic data describing patellar sleeve fractures, along with outcomes following non-operative and operative treatments. Level of evidence: IV.

Background: Irreparable rotator cuff tears represent approximately 12% of all presenting cuff tears, and multiple surgical techniques have been described for treatment, including allograft/bridge augmentation, debridement, partial repair, subacromial balloon, tendon transfer, and superior capsule reconstruction (SCR). SCR has demonstrated durable improvement in range of motion (ROM) and outcome scores at 2 and 5 years. Indications: Surgical indications for SCR include an irreparable tear of the supraspinatus and/or infraspinatus with a preserved or reparable subscapularis and preserved glenohumeral joint cartilage. Technique Description: Diagnostic arthroscopy is performed to identify and characterize the rotator cuff tear. Thorough debridement of the greater tuberosity is performed. Two all-suture FiberTak anchors are placed in the superior aspect of the glenoid. Two 2.6-mm FiberTak suture anchors are placed in the humeral head at the chondral margin. After measuring, the dermal allograft is cut to size with 15-mm overhang left on the far lateral edge. A 12-mm passport cannula is inserted laterally and the sutures from the glenoid and humeral head anchors are brought out through the cannula maintaining their position and orientation. The sutures are passed through the graft outside the cannula. The graft is introduced into the shoulder via the passport cannula with a back grasper. A cannula-in-cannula technique is used to tie the glenoid anchors first and then the medial row anchors. Two lateral row swivel lock anchors are used to complete a standard double row repair. Margin convergence is performed between the dermal allograft and remaining rotator cuff anterior and posterior. Postoperatively, patients are kept in a sling for 6 weeks, with no shoulder ROM. From weeks 6 to 12, patients discontinue sling and begin passive progression to active ROM. Strengthening is initiated at 12 weeks, and return-to-sport or work is at approximately 6 months. Results: Irreparable rotator cuff tears treated with arthroscopic rotator cuff repair and SCR show durable improvement in patient-reported outcomes at 2 and 5 years. Re-tear rates did not differ between athletes and non-athletes. Discussion/Conclusion: Arthroscopic rotator cuff repair with SCR is a durable and reliable surgical option for patients presenting with preserved glenohumeral joint and irreparable supraspinatus and/or infraspinatus tear.

Background: Social media use has grown across healthcare delivery and practice, with dramatic changes occurring in response to the coronavirus (COVID-19) pandemic. The purpose of this study was to conduct a comprehensive systematic review to determine the current landscape of social media use by (1) orthopaedic surgery residencies/fellowship training programs and (2) individual orthopaedic surgeons and the change in use over time. Methods: We searched 3 electronic databases (PubMed, MEDLINE, and Embase) from their inception to April 2022 for all studies that analyzed the use of social media in orthopaedic surgery. Two reviewers independently determined study eligibility, rated study quality, and extracted data. Methodology was in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results: Twenty-eight studies were included, of which 11 analyzed social media use by orthopaedic surgery residency and fellowship training programs and 17 examined its use by individual orthopaedic surgeons. Among residency and fellowship programs, Instagram was identified as the most common platform used, with 42% to 88% of programs reporting program-specific Instagram accounts, followed by Twitter/X (20%-52%) and Facebook (10%-38%). Social media was most commonly used by programs for recruitment and information dissemination to prospective residency applicants (82% and 73% of included studies, respectively). After the start of the COVID-19 pandemic, there was a 620% and 177% increase in the number of training programs with Instagram and Twitter/X accounts, respectively. Individual use of social media ranged from 1.7% to 76% (Twitter/X), 10% to 73% (Facebook), 0% to 61% (Instagram), 22% to 61% (LinkedIn), and 6.5% to 56% (YouTube). Conclusions: Instagram, Twitter/X, and Facebook are the premier platforms that patients, residency applicants, and institutions frequent. With the continued growth of social media use anticipated, it will be critical for institutions and individuals to create and abide by guidelines outlining respectful and professional integration of social media into practice. Level of Evidence: Level IV.

» The scaphotrapeziotrapezoid (STT) joint is a common location of degenerative osteoarthritis (OA) in the wrist. » STT OA may occur in isolation or with concomitant thumb carpometacarpal joint (CMCJ) OA or scapholunate advanced collapse (SLAC) and other wrist OA patterns. » Nonoperative management strategies include activity modification, bracing, anti-inflammatory medications, occupational therapy, and injections. » Surgical treatment may be determined by whether the STT OA occurs in isolation or with concomitant thumb CMCJ or SLAC OA and includes STT arthrodesis, distal scaphoid excision with or without interposition or implant arthroplasty, trapeziectomy with proximal trapezoid excision, four-corner fusion in combination with scaphoid/radial column excision, and proximal row carpectomy.

Background: Although hip bracing after hip arthroscopy is relatively common, it is not an evidence-based practice; no comparative studies or clinical trials exploring its effectiveness exist. Purpose: We sought to summarize the rates of and indications for hip bracing after hip arthroscopy, surgeons’ preferences on braces, and the types of braces used. Methods: A systematic review was conducted using the PubMed, Embase, and Medline databases to identify studies that examined hip bracing following hip arthroscopy. Two independent reviewers identified relevant studies with final inclusion determined by the senior author. Full-length, original research articles regarding relevant subject matter that were published prior to January 2022 were included in the analysis. Results: Of the 52 articles that underwent full-text review, 14 were included (10 clinical case series, comparative studies, or case-control studies and 4 cross-sectional studies of surgeon-specific postoperative rehabilitation protocols). These studies revealed that the practice of hip bracing after hip arthroscopy is relatively common among orthopedic surgeons, with up to 40% of surgeons using them. Surgical indications for postoperative brace use varied widely. Recommendations on the length of brace use varied, but range of motion restrictions were consistent. Conclusions: Although up to 40% of surgeons use post-hip arthroscopy bracing, there is insufficient evidence to determine whether it improves patient outcomes. Research producing higher levels of evidence regarding the efficacy of bracing following hip arthroscopy is necessary to understand the physical, mental, and economic costs and benefits to patients.
