RESUMO
BACKGROUND: The sphericity of the femoral head is a metric used to evaluate hip pathologies and is associated with the development of osteoarthritis and femoral-acetabular impingement. AIM: To analyze the three-dimensional asphericity of the femoral head of asymptomatic pediatric hips. We hypothesized that femoral head asphericity will vary significantly between male and female pediatric hips and increase with age in both sexes. METHODS: Computed tomography scans were obtained on 158 children and adolescents from a single institution in the United States (8-18 years; 50% male) without hip pain. Proximal femoral measurements including the femoral head diameter, femoral head volume, residual volume, asphericity index, and local diameter difference were used to evaluate femoral head sphericity. RESULTS: In both sexes, the residual volume increased by age (P < 0.05). Despite significantly smaller femoral head size in older ages (> 13 years) in females, there were no sex-differences in residual volume and aspherity index. There were no age-related changes in mean diameter difference in both sexes (P = 0.07) with no significant sex-differences across different age groups (P = 0.06). In contrast, there were significant increases in local aspherity (maximum diameter difference) across whole surface of the femoral head and all quadrants except the inferior regions in males (P = 0.03). There were no sex-differences in maximum diameter difference at any regions and age group (P > 0.05). Increased alpha angle was only correlated to increased mean diameter difference across overall surface of the femoral head (P = 0.024). CONCLUSION: There is a substantial localized asphericity in asymptomatic hips which increases with age in. While 2D measured alpha angle can capture overall asphericity of the femoral head, it may not be sensitive enough to represent regional asphericity patterns.
RESUMO
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 OF REVIEW: The purpose of this review is to summarize current clinical knowledge on the prevalence and types of meniscus pathology seen with concomitant anterior cruciate ligament (ACL) injury, as well as surgical techniques, clinical outcomes, and rehabilitation following operative management of these pathologies. RECENT FINDINGS: Meniscus pathology with concomitant ACL injury is relatively common, with reports of meniscus pathology identified in 21-64% of operative ACL injuries. These concomitant injuries have been associated with increased age and body mass index. Lateral meniscus pathology is more common in acute ACL injury, while medial meniscus pathology is more typical in chronic ACL deficiency. Meniscus tear patterns associated with concomitant ACL injury include meniscus root tears, lateral meniscus oblique radial tears of the posterior horn (14%), and ramp lesions of the medial meniscus (8-24%). These meniscal pathologies with concomitant ACL injury are associated with increased rotational laxity and meniscal extrusion. There is a paucity of comparative studies to determine the optimal meniscus repair technique, as well as rehabilitation protocol, depending on specific tear pattern, location, and ACL reconstruction technique. There has been a substantial increase in recent publications demonstrating the importance of meniscus repair at the time of ACL repair or reconstruction to restore knee biomechanics and reduce the risk of progressive osteoarthritic degeneration. Through these studies, there has been a growing understanding of the meniscus tear patterns commonly identified or nearly missed during ACL reconstruction. Surgical management of meniscal pathology with concomitant ACL injury implements the same principles as utilized in the setting of isolated meniscus repair alone: anatomic reduction, biologic preparation and augmentation, and circumferential compression. Advances in repair techniques have demonstrated promising clinical outcomes, and the ability to restore and preserve the meniscus in pathologies previously deemed irreparable. Further research to determine the optimal surgical technique for specific tear patterns, as well as rehabilitation protocols for meniscus pathology with concomitant ACL injury, is warranted.
RESUMO
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.
RESUMO
A 29-year-old right-handed woman presented to an outside emergency department with right small finger pain, swelling, and concern for a retained wooden splinter. Diagnosis and treatment were delayed for 2 weeks due to the inability to identify the foreign body clinically or radiographically. Ultimately, ultrasonography by a fellowship-trained specialist was used to localize the wooden splinter. It was embedded within the flexor tendon sheath but had migrated away from its initial point of entry. The patient underwent subsequent surgical extraction, irrigation, and debridement. Two weeks following surgery, she had regained full range of motion through her digit without signs of infection. This case highlights the use of diagnostic ultrasound to identify a radiolucent foreign body, such as a wooden splinter, and to guide subsequent surgical extraction.
RESUMO
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.
RESUMO
¼ The scaphotrapeziotrapezoid (STT) joint is a common location of degenerative osteoarthritis (OA) in the wrist.¼ STT OA may occur in isolation or with concomitant thumb carpometacarpal joint (CMCJ) OA or scapholunate advanced collapse (SLAC) and other wrist OA patterns.¼ Nonoperative management strategies include activity modification, bracing, anti-inflammatory medications, occupational therapy, and injections.¼ 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.

The purpose of this study was to review the current literature on perioperative pain management in hip arthroscopy, periacetabular osteotomy and surgical hip dislocation. A systematic review of the literature published from January 2000 to December 2022 was performed. Selection criteria included published randomized controlled trials, prospective reviews and retrospective reviews of all human subjects undergoing hip preservation surgery. Exclusion criteria included case reports, animal studies and studies not reporting perioperative pain control protocols. Thirty-four studies included hip arthroscopy in which peripheral nerve blocks were associated with a significant reduction in pain score (P = 0.037) compared with general anesthesia alone. However, no pain control modality was associated with a significant difference in postanesthesia care unit opioid use (P = 0.127) or length of stay (P = 0.251) compared with general anesthesia alone. Falls were the most common complication reported, accounting for 37% of all complications. Five studies included periacetabular osteotomy and surgical hip dislocation in which peripheral nerve blocks were associated with an 18% reduction in pain on postoperative Day 2, a 48% reduction in cumulative opioid use on postoperative Day 2 and a 40% reduction in hospital stay. Due to the low sample size of the periacetabular osteotomy and surgical hip dislocation studies, we were unable to determine the significant difference between the means. Due to significant between-study heterogeneity, additional studies with congruent outcome measures need to be conducted to determine the efficacy of regional anesthesia in hip arthroscopy, periacetabular osteotomy and surgical hip dislocation.
RESUMO
BACKGROUND: The extent to which recurrent patellar instability (RPI) affects wrestlers has not been thoroughly examined. PURPOSE: To assess return to wrestling (RTW), patient-reported outcomes, and reoperation rates after patellofemoral stabilization surgery (PFSS) for RPI in a cohort of competitive wrestlers. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: All competitive wrestlers with a history of RPI and subsequent PFSS performed at a single institution between 2000 and 2020 were identified. Primary PFSS procedures included medial patellofemoral (MPFL) reconstruction (n = 31; 50%); MPFL repair (n = 22; 35.5%); or other PFSS (n = 9; 14.5%), such as tibial tubercle osteotomy, lateral retinacular release, and/or medial retinacular reefing. Exclusion criteria included revision PFSS or concomitant anterior cruciate ligament reconstruction or multiligament knee injury. Surgical failure was defined as subsequent patellar dislocation despite operative management or need for secondary PFSS. RESULTS: Ultimately, 62 knees in 56 wrestlers with a mean age of 17.0 years (range, 14.0-22.8 years) were included at a mean follow-up of 6.6 years (range, 2.0-18.8 years). RTW occurred in 55.3% of wrestlers at a mean ± SD 8.8 ± 6.7 months. Among PFSS types, no differences were observed in rates of RTW (P = .676), postoperative pain (P = .176), Tegner activity level (P = .801), International Knee Documentation Committee (P = .378), Lysholm (P = .402), or Kujala scores (P = .370). RPI was the most common postoperative complication (n = 13; 21.0%). MPFL reconstruction had the lowest rate of RPI (6.5% vs 27.3% [repair] vs 55.6% [other]; P = .005) and surgical failure (9.7% vs 31.8% [repair] vs 55.6% [other]; P = .008). Kaplan-Meier survivorship free from surgical failure of the entire cohort was 91.9% at 1 year, 77.7% at 5 years, and 65.7% at 15 years. MPFL reconstruction had the highest survivorship when compared with MPFL repair and other PFSS up to 10 years after the index surgery (90.3% vs 64.1% vs 27.8%; P = .048). CONCLUSION: RPI remains a concern for competitive wrestlers after PFSS. MPFL reconstruction may serve as a more durable surgical treatment option with lower rates of RPI and failure when compared with other PFSS procedures at up to 10 years after surgery.

CASE: A 20-year-old man sustained a comminuted bone-patellar tendon-bone donor-site fracture 17 days after a contralateral anterior cruciate ligament revision reconstruction. Successful fixation was achieved by using a tricortical iliac crest allograft bone plug with mesh plate osteosynthesis. At 6 months of follow-up, the patient had full range of motion without pain. CONCLUSION: Patellar fractures after bone-patellar tendon-bone harvest may be treated successfully with mesh plate osteosynthesis and a tricortical iliac crest allograft bone plug. This unique fixation option addresses bone loss and restores the extensor mechanism while avoiding autograft donor site morbidity.

The orthopaedic surgery residency selection process has grown more competitive over recent years, with programs receiving an unprecedented number of applications. As an effort to target applications to programs of interest, the American Orthopaedic Association has announced the introduction of a formal preference-signaling program into the 2022 to 2023 orthopaedic surgery residency selection cycle. This system will allow applicants to assign "signals" to a total of 30 programs. The purpose of this article was to (1) discuss implications of the new preference-signaling program, (2) introduce the framework of the "strategic signaling spear" for applicants to conceptualize the power of all methods of preference-signaling to improve their odds of matching, and (3) describe the role of strong mentorship at all stages of the residency application process.

Conventional adult anterior cruciate ligament reconstruction techniques are controversial in skeletally immature patients due to the risk of iatrogenic physeal damage and potential growth disturbance. The physeal-sparing, combined intra- and extra-articular anterior cruciate ligament reconstruction using an autogenous iliotibial band was developed to mitigate this risk in prepubescent, skeletally immature patients, with excellent functional outcomes and a low revision rate. This article describes the surgical details of this reproducible reconstruction technique.
RESUMO
Pigmented villonodular synovitis (PVNS) and synovial chondromatosis (SC) of the hip are rare synovial diseases that can induce joint destruction without early diagnosis and treatment. The extent of surgical excision is critical given the high rates of recurrence. In the presented case, a 19-year-old female was referred to our institution with progressive left hip pain and radiologic evidence of an intra-articular mass that was consistent with PVNS versus SC. Her medical history was notable for a prior excision of a fibrous lesion at an outside hospital at age 13 with persistent pain. The patient underwent a surgical hip dislocation approach to obtain near-complete visualization of the femoroacetabular joint, ensuring complete evaluation and excision. The tumor was intraoperatively diagnosed as SC and excised accordingly, during an uneventful operation. Pathology confirmed the diagnosis. The essential diagnostic and surgical steps for the management of this pelvic tumor diagnostic dilemma are described. Level of Evidence: V.

The use of computer-navigated, robotic-assisted total knee arthroplasty (TKA) is expanding as the result of widespread efforts to improve the precision of implant placement and to restore mechanical, anatomic, and kinematic alignment. The procedure requires placement of femoral and tibial pins to mount the robotic tracking system. Fractures through tracking pin sites following robotic-assisted TKA are rare; only 30 cases have been reported to our knowledge. It is probable that this complication will become more frequent as the use of robotic-assisted TKAs continues to grow. We report the case of a 67-year-old female who suffered a fracture of the femur through two pin sites 3 months after a robotic-assisted TKA. We believe that this report is the first case in the radiologic literature. Our case demonstrates some of the difficulties of recognizing this complication and raises questions about appropriate post-operative imaging.

BACKGROUND: Heterotopic ossification (HO) is a known complication after hip arthroscopy in adults, positively associated with larger cam resection, male sex, older age, and obesity, and negatively associated with nonsteroidal anti-inflammatory drug (NSAID) use and capsular closure. However, it has not been well-documented in adolescents. The purpose of this study was to determine the incidence and risk factors for the development of HO in adolescent patients undergoing hip arthroscopy. METHODS: Clinical and operative records from a pediatric institution were queried to identify patients aged 21 years or younger who underwent hip arthroscopy between 2008 and 2018. The 27 cases that developed HO were matched 1:4 on age and sex with 107 controls. The bivariate analysis assessed the relationship between demographic and perioperative factors on the development of HO. Multivariable logistic regression evaluated the association between prophylactic NSAID use (indomethacin 75 mg, 3 wk) and HO, controlling for surgeon and extent of cam resection (change in alpha angle). RESULTS: Twenty-seven of 595 (4.5%) hips that underwent hip arthroscopy developed HO within 2 years of surgery. Prophylactic indomethacin was not significantly associated with developing HO [30% (8/27), P=0.83], after controlling for surgeon and extent of cam resection-nor were age, sex, and body mass index percentile. Of patients who developed HO, a smaller proportion underwent reoperation for HO excision among those who received prophylactic indomethacin than those who did not [13% (1/8) vs. 63% (12/19), P=0.03]. CONCLUSIONS: The incidence of HO within 2 years of hip arthroscopy in this adolescent population was 4.5%. Although studies in the adult hip arthroscopy population have pointed to a protective role of NSAIDs (eg, indomethacin) in radiographic HO, the effect was less certain in this adolescent sample. Larger studies are important to further evaluate the role of prophylactic NSAIDs and variations in arthroscopic technique in developing HO. LEVEL OF EVIDENCE: Level III-therapeutic, case-control study.

BACKGROUND: The novel Kocher classification is a 3-group magnetic resonance imaging (MRI) classification system for osteochondritis dissecans (OCD) of the knee that was shown to have comparable reliability to that of the established 5-group Hefti classification. The purpose of this study was to evaluate the validity and clinical utility of this simplified system as an alternative to the Hefti classification. METHODS: Demographic data and arthroscopic findings were retrospectively collected from medical and surgical records of 144 consecutive knees in children with arthroscopically diagnosed knee OCD. OCD lesions on preoperative MRIs and surgical reports (serving as the reference standard) were assessed by independent raters and assigned both a Kocher and Hefti classification. Agreement between MRI classification and arthroscopic findings for both systems was assessed using weighted kappa (kw) coefficients. Validation, accuracy, sensitivity, and specificity were measured by comparing a dichotomized Kocher classification for MRI and arthroscopy, and by estimating Cohen kappa (kc) coefficients. Agreement between arthroscopic findings and treatment type was measured using the Spearman correlation coefficient. RESULTS: Inter-rater reliability between the 2 MRI raters was substantial for the Kocher classification [ka=0.66; 95% confidence interval (CI)=0.56-0.75] and moderate for the Hefti classification (ka=0.57; 95% CI=0.47-0.67). There was no difference detected in the agreement statistics for Kocher versus Hefti classifications (P=0.89). Binary agreement using dichotomized Kocher classifications was worse than the 3-group category classification. When dichotomized, combining Kocher grades 1 and 2 demonstrated moderate agreement (kc=0.41; 95% CI=0.25-0.58), and combining grades 2 and 3 demonstrated fair agreement (kc=0.34; 95% CI=0.21-0.48). There was a strong correlation between arthroscopy-based finding and treatment category for both the Kocher classification (r=0.85; 95% CI=0.80-0.89) and the Hefti classification (r=0.82; 95% CI=0.75-0.86). CONCLUSION: The validity and clinical utility of the newer 3-group Kocher classification for knee OCD is comparable to that of the well-established 5-group Hefti classification. Both systems help determine lesion stability and characteristics on MRI, which correlate closely to arthroscopic findings. This simplified classification system, with less uncertainty, provides a foundation for further outcomes research to develop an evidence-based algorithm for effective surgical management of OCD lesions of the knee. LEVEL OF EVIDENCE: Level II-diagnostic study.

BACKGROUND: Lesbian, gay, bisexual, transgender, and queer (LGBTQ) children and adolescents continue to experience unmet healthcare needs, partly because of clinician biases, discrimination, and inadequate education. Although clinician attitudes and knowledge related to sexual and gender minority health have been well studied in other medical specialties, these have been scarcely studied in orthopaedics. QUESTIONS/PURPOSES: (1) What are pediatric orthopaedic healthcare professionals' attitudes (perceived importance, openness, comfort, and confidence) toward caring for sexual and gender minority youth? (2) What do pediatric orthopaedic healthcare professionals know about caring for this patient population? (3) What factors are associated with clinician attitude and/or knowledge? (4) What existing initiatives to improve orthopaedic care for this population are clinicians aware of at their home institutions? METHODS: All 123 orthopaedic healthcare professionals at two pediatric academic hospitals in the Midwestern and Northeastern United States were sent a 34-question, internet-based, anonymous survey. The survey queried respondent demographics, attitudes, knowledge, and practice behaviors at their home institutions related to the care of sexual and gender minority youth. Respondent attitudes were queried using the Attitudes Summary Measure, which is a survey instrument that was previously validated to assess clinicians' attitudes regarding sexual and gender minority patients. Items used to assess knowledge and practice behaviors were developed by content experts in LGBTQ health and/or survey design, as well as orthopaedic surgeons to improve face validity and to mitigate push-polling. Attitude and knowledge items used a 5-point Likert scale. Sixty-six percent (81 of 123) of clinicians completed the survey. Of those, 47% (38 of 81) were physicians, 73% (59 of 81) were licensed for fewer than 20 years, 63% (51 of 81) were women, and 53% (43 of 81) described themselves as liberal-leaning. The response proportions were 73% (38 of 52) among eligible physicians specifically and 61% (43 of 71) among other clinicians (nurse practitioners, physician assistants, and registered nurses). To assess potential nonresponse bias, we compared early responders (within 2 weeks) with late responders (after 2 weeks) and found no differences in responder demographics or in questionnaire responses (all p > 0.05). The main outcome measures included responses to the attitude and knowledge questionnaire, as well as the existing practices questionnaire. To answer our research questions regarding clinician attitudes knowledge and awareness of institutional initiatives, we compared participant responses using chi-square tests, the Student t-test, and the McNemar tests, as appropriate. To answer our research question on factors associated with questionnaire responses, we reported data for each question, stratified by hospital, years since licensure, and political leaning. Comparisons were conducted across strata using chi-square tests for Likert response items and ANOVA for continuous response items. All p values less than 0.05 were considered significant. RESULTS: Of the respondents who reported feeling comfortable treating lesbian, gay, and bisexual (sexual minority) youth, a small proportion reported feeling confident in their knowledge about these patients' health needs (99% [80 of 81] versus 63% [51 of 80], 36% reduction [95% confidence interval 23% to 47%]; p < 0.001). Similarly, of those who reported feeling comfortable treating transgender (gender minority) youth, a smaller proportion reported feeling confident in their knowledge of their health needs (94% [76 of 81] versus 49% [37 of 76], 45% reduction [95% CI 31% to 59%]; p < 0.001). There was substantial interest in receiving more education regarding the health concerns of LGBTQ people (81% [66 of 81]) and being listed as an LGBTQ-friendly clinician (90% [73 of 81]). Factors that were associated with select attitude and knowledge items were duration of licensure and political leaning; gender identity, institutional affiliation, educational degree, or having LGBTQ friends and family were not associated. Many respondents were aware of the use of clinic intake forms and the electronic medical record to collect and provide patient gender identity and sexual orientation data at their practice, as well as signage and symbols (for example, rainbow posters) to cultivate LGBTQ-welcoming clinic spaces. CONCLUSION: There were varying degrees of confidence and knowledge regarding the health needs of sexual and gender minority youth among pediatric orthopaedic healthcare professionals. There was considerable interest in more focused training and better use of medical technologies to improve care for this population. CLINICAL RELEVANCE: The study findings support the further investment in clinician training opportunities by healthcare administrators and orthopaedic associations related to the care of sexual and gender minority patients, as well as in the expansion of medical documentation to record and report important patient information such as pronouns and gender identity. Simultaneously, based on these findings, clinicians should engage with the increasing number of educational opportunities, explore their personal biases, and implement changes into their own practices, with the ultimate goal of providing equitable and informed orthopaedic care.

BACKGROUND: Despite the presence of multiple classification systems for discoid meniscus, no system has yet to demonstrate utility in predicting the need for meniscal repair. The purpose of this study was to correlate characteristics associated with meniscal repair and propose a model that can inform preoperative planning and initial counseling of surgical plans and expectations. METHODS: Medical and operative records of 434 knees with lateral discoid meniscus in children and adolescents treated between 1991 and 2016 were reviewed retrospectively to determine the surgical procedure performed (saucerization with or without meniscal repair), discoid meniscal morphology and stability, and location and type of any associated tear. Univariate associations between discoid meniscal characteristics and surgery type were calculated and a logistic regression model of surgery type was generated. RESULTS: In univariate models, unstable menisci (93%, or 179/204, P<0.001) and menisci with tears extending peripherally (75%, or 85/204, P<0.001) were more likely to receive surgery with repair. In isolation, instability demonstrated 89% sensitivity and 94% specificity in predicting surgery with repair. A logistic regression model including stability, tear, and their interaction (stability×tear) showed that that the odds of unstable lateral discoid menisci receiving surgery with repair was 114 times higher than stable menisci (P<0.001) while lateral discoid menisci with peripherally extending tears had 6.4 times higher odds of receiving repair than those that had an isolated central tear (P<0.001). CONCLUSION: Stability and tear location of lateral discoid menisci were associated with surgical treatment in univariate and logistic regression models. The proposed classification system, in which menisci are classified by stability [Stable (S0), Unstable (S1), morphology (Incomplete (M0), Complete (M1))], and tear [No tear (T0), Central tear, isolated (T1), or Central tear, peripheral extension (T2)], is easily remembered and predicts surgical repair for discoid menisci. This scheme can serve to inform preoperative planning and initial counseling of primary surgical management and postoperative expectations. Subsequent research should develop a system that predicts meniscal survival and patient outcomes following the index operation. LEVEL OF EVIDENCE: Level III.

Femoroacetabular impingement (FAI) is a common femoral and/or acetabular abnormality that can cause progressive damage to the hip and osteoarthritis. FAI can be the result of femoral head/neck overgrowth, acetabular overgrowth or both femoral and acetabular abnormalities, resulting in a loss of native hip biomechanics and pain upon hip flexion and rotation. Radiographic evidence can include loss of sphericity of the femoral neck (cam impingement) and/or acetabular retroversion with focal or global overcoverage (pincer impingement). Operative intervention is indicated in symptomatic patients after failed conservative management with radiographic evidence of impingement and minimal arthritic changes of the hip, with the goal of restoring normal hip biomechanics and reducing pain. This is done by correcting the femoral head-neck relationship to the acetabulum through femoral and/or acetabular osteoplasty and treatment of concomitant hip pathology. In pincer impingement cases with small lunate surfaces, reverse periacetabular osteotomy is indicated as acetabular osteoplasty can decrease an already small articular surface. While surgical dislocation is regarded as the traditional gold standard, hip arthroscopy has become widely utilized in recent years. Studies comparing both open surgery and arthroscopy have shown comparable long-term pain reduction and improvements in clinical measures of hip function, as well as similar conversion rates to total hip arthroplasty. However, arthroscopy has trended toward earlier improvement, quicker recovery and faster return to sports. The purpose of this study was to review the recent literature on open and arthroscopic management of FAI.
