RESUMO
With the pronounced ongoing growth of global youth sports, opportunities for and participation of youth athletes on the world sports stage, including the Olympic Games, are expected to escalate. Yet, adolescence is a vulnerable period of development and inherently dynamic, with non-linear and asynchronous progression of physical, physiological, psychological and social attributes. These non-concurrent changes within and between individuals are accompanied by irregular and unpredictable threats and impediments. Likewise, the evident age-based criteria and conventional path for those youth athletes deemed eligible candidates for the Olympic Games are not well or consistently defined. Furthermore, the unstructured and largely varying policies and practices across the sporting International Federations specific to youth participation underscore the need to establish a contemporary universal paradigm that would enable elite youth athletes to navigate an individualised healthy pathway to personal, athletic and sport success. First, we reviewed and summarised key challenges facing elite youth athletes and the relevant evidence fundamental to facilitating and supporting central aspects of health and well-being, while empowering safe, sustainable and positive engagement during athletic and personal advancement and competition. Second, we developed and present a modern elite youth athlete model that emphasises a child-centred, practical framework with corresponding guidelines and recommendations to protect health and well-being while safely and favourably managing international sport competition. Our proposed evidence-informed paradigm will enable and support individualised pathways for healthy, well-rounded and sustainable positive engagement while achieving sport success for youth contending or aiming to compete at world-class international sporting events.
RESUMO
BACKGROUND: Social determinants of health (SDOHs) affect health outcomes outside the hospital, and understanding them can enhance postoperative outcomes in orthopaedic surgery patients. This study aimed to describe the prevalence of randomized controlled trials (RCTs) in pediatric orthopaedic journals reporting on the SDOHs of their patient cohorts. We hypothesize that many SDOHs will be underreported in RCTs investigating pediatric orthopaedic surgery. METHODS: Utilizing the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, the authors queried the PubMed database to examine SDOHs from 2 pediatric orthopaedic journals: Journal of Pediatric Orthopaedics and Journal of Pediatric Orthopaedics: Part B. The inclusion criteria incorporated RCTs published between 2005 and April 2024. The exclusion criteria included any articles that were not RCTs published in this period. RESULTS: One hundred thirteen articles met the search criteria, with 31 excluded because they did not fall from 2005 to 2024. Eighty-two were published from 2005 to 2024, but 6 RCTs were excluded, as 3 were non-RCTs, and 3 examined cadavers. Seventy-six RCTs were included for analysis, with 65 articles from the Journal of Pediatric Orthopaedics and 11 articles from the Journal of Pediatric Orthopaedics: Part B. Articles originated from 17 countries, with the United States producing 61.8% (47) of the included studies. Of all 76 included studies, 96.1% (73) reported age, 88.2% (67) reported sex/gender, 30.3% (23) reported BMI, 21.1% (16) reported race/ethnicity, 5.3% (4) reported educational level, 2.6% (2) reported stress, and 2.6% (2) reported insurance. Smoking status, socioeconomic status, income levels, and employment status were each reported by only 1 study. CONCLUSIONS: The RCTs examining pediatric orthopaedic surgery tend to scarcely report SDOHs. Future RCTs should expand beyond demographic characteristics such as age, race/ethnicity, sex/gender, and BMI and incorporate other relevant SDOHs. This will allow us to develop a more comprehensive understanding of health outcomes in the pediatric orthopaedic population. LEVEL OF EVIDENCE: I; Therapeutic Studies.
RESUMO
BACKGROUND: Shortening of midshaft clavicle fractures has been described as a critical fracture characteristic to guide treatment. The degree to which shortening may change in the initial weeks following injury has not been well studied. The purpose of this study was to evaluate the change in shortening of adolescent clavicle fractures in the first 2 weeks following injury. METHODS: This was a multicenter study of prospectively collected data, which was acquired as a part of a cohort study of adolescent clavicle fractures. A consecutive series of patients 10 to 18 years of age with completely displaced diaphyseal clavicle fractures with baseline radiographs 0 to 6 days from the date of injury, as well as 7 to 21 days from the date of injury, were included. Measurements of end-to-end (EES) and cortex-to-corresponding-cortex (CCS) shortening were performed. RESULTS: A total of 142 patients were included. Baseline radiographs were obtained at a mean of 1.0 day following injury with mean EES of 22.3 mm, and 69% of patients demonstrating > 20 mm of shortening. Follow-up radiographs obtained at a mean of 13.8 days postinjury demonstrated a mean absolute change in EES of 5.4 mm. Forty-one percentage of patients had >5 mm of change in EES. When analyzing changes in shortening relative to the specific threshold of 20 mm, 18 patients (41%) with <20 mm EES increased to ≥20 mm EES, and 19 patients (19%) with ≥20 mm EES decreased to <20 mm EES at 2-week follow-up. CONCLUSIONS: Clinically significant changes in fracture shortening occurred in 41% of adolescents with completely displaced clavicle fractures in the first 2 weeks after injury. In 26% of patients, this resulted in a change from above or below the commonly used shortening threshold of 20 mm, potentially altering the treatment plan by many providers. There is no evidence to suggest that adolescent clavicle fracture shortening affects outcomes, and as such, the authors do not advocate for the use of this parameter to guide treatment. However, among physicians who continue to use this parameter to guide treatment, this study supports that repeat radiographic assessment 2 weeks postinjury may be a better measure of the true shortening of this common adolescent injury. LEVEL OF EVIDENCE: Level IV-case series.

BACKGROUND: Radiographic measurements of limb alignment in skeletally immature patients with anterior cruciate ligament (ACL) tears are frequently used for surgical decision-making, preoperative planning, and postoperative monitoring of skeletal growth. However, the interrater and intrarater reliability of these radiographic characteristics in this patient population is not well documented. HYPOTHESIS: Excellent reliability across 4 raters will be demonstrated for all digital measures of length, coronal plane joint orientation angles, mechanical axis, and tibial slope in skeletally immature patients with ACL tears. STUDY DESIGN: Cohort study (diagnosis). METHODS: Three fellowship-trained orthopaedic surgeons and 1 medical student performed 2 rounds of radiographic measurements on digital imaging (lateral knee radiographs and long-leg radiographs) of skeletally immature patients with ACL tears. Intrarater and interrater reliability for continuous radiographic measurements was assessed with intraclass correlation coefficients (ICCs) across 4 raters with 95% CIs for affected and unaffected side measurements. Interrater reliability analysis used an ICC (2, 4) structure and intrarater reliability analysis used an ICC (2, 1) structure. A weighted kappa coefficient was calculated for ordinal variables along with 95% CIs for both interrater and intrarater reliability. Agreement statistic interpretations are based on scales described by Fleiss, and Cicchetti and Sparrow: <0.40, poor; 0.40 to 0.59, fair; 0.60 to 0.74, good; and >0.74, excellent. RESULTS: Radiographs from a convenience sample of 43 patients were included. Intrarater reliability was excellent for nearly all measurements and raters. Interrater reliability was also excellent for nearly all reads for all measurements. CONCLUSION: Radiographic reliability of long-leg radiographs and lateral knee x-rays in skeletally immature children with ACL tears is excellent across nearly all measures and raters and can be obtained and interpreted as reliable and reproducible means to measure limb length and alignment. LEVEL OF EVIDENCE: Level III.

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.

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: 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: Progressive displacement of diaphyseal clavicle fractures has been observed in adult patients, at times necessitating a change from nonoperative to operative treatment. Whether this occurs in adolescent patients has not been well investigated. The purpose of this study was to assess the rate and extent of progressive clavicle fracture displacement in adolescent patients following injury and during the early stages of healing. METHODS: This was a multicenter study evaluating prospective data that had previously been collected as part of a larger study evaluating the functional outcomes of adolescent clavicle fractures. A consecutive series of completely displaced diaphyseal clavicle fractures in patients aged 10-18 years treated at 1 of 3 tertiary-care pediatric trauma centers was included; all fractures underwent standardized imaging within 2 weeks of the date of injury and during the course of healing (5-20 weeks after injury). Measurements of clavicle shortening, superior displacement, and angulation were performed using validated techniques. Progressive displacement and/or interval improvement in fracture alignment, as well as the subsequent need for surgical intervention, was noted. Patient demographic and radiographic parameters were assessed as possible risk factors for interval displacement. RESULTS: One hundred patients met the inclusion criteria. Mean end-to-end shortening, cortex-to-cortex shortening, superior displacement, and angulation at the time of injury were 24 mm, 15 mm, 15 mm, and 7°, respectively. At a mean of 10 weeks after injury, the fracture alignment improved across all 4 measurements for the overall cohort, with mean improvements of 3.5 mm in end-to-end shortening, 3.3 mm in cortex-to-cortex shortening, 2.1 mm in superior displacement, and 2° in angulation. By use of a clinical threshold of a change in shortening or displacement of 10 mm or change in angulation of 10°, 26% of fractures improved, 4% worsened, and 70% remain unchanged. Patients with more severe fractures were more likely to have improved alignment than were patients with less displaced fractures (P < .001). No patient underwent surgical intervention for progressive displacement. CONCLUSION: Significant early improvements in fracture alignment were observed in a substantial percentage of adolescent patients with completely displaced clavicle fractures. Among the most severely displaced fractures, shortening improved approximately 6 mm and angulation improved approximately 9°. In 4% of cases, increased displacement was observed, but this tended to be mild, and in no cases did it prompt surgical intervention. This finding indicates that the true final deformity after an adolescent clavicle fracture is commonly less than that present at the time of injury.

BACKGROUND: Previous studies have suggested that hip arthroscopy has been performed with increasing frequency. Few studies have examined this trend in the adolescent population. The purpose of this study was to evaluate the trend in the frequency of hip arthroscopy in adolescents standardized by total orthopaedic surgeries in adolescents at pediatric hospitals in the United States. METHODS: The Pediatric Health Information System (PHIS) database was queried for patients aged 10 to 19 years who underwent orthopaedic surgery at any of the PHIS-participating hospitals from 2008 to 2018. The subgroup of patients in this age cohort who underwent hip arthroscopy was identified using Current Procedural Terminology procedure codes. The yearly rate was expressed as the number of hip arthroscopies per 1000 orthopaedic surgeries. A linear model was used to fit the data and illustrate the relative trend. RESULTS: A total of 432,309 orthopaedic surgeries including 9491 hip arthroscopies were performed for patients 10 to 19 years of age. Hip arthroscopies were performed at a yearly rate of 22 per 1000 orthopaedic surgeries. Over the 10-year period, the number of hip arthroscopies increased 6.2-fold, whereas the number of orthopaedic procedures increased 1.6-fold. There was a 3.9-fold increase in hip arthroscopies relative to total orthopaedic surgeries. CONCLUSIONS: The number of hip arthroscopic procedures in adolescent patients has increased by 3.9-fold times relative to total orthopaedic surgeries in adolescents over a 10-year span, on the basis of data from PHIS-participating institutions. This finding mirrors the trends in the adult population over similar time periods. This may be because of increasing participation in sports in the adolescent population, and a better understanding of the diagnosis and treatment of femoroacetabular impingement and other sports-related hip pathologies. LEVEL OF EVIDENCE: Level IV.

BACKGROUND: Current advanced imaging classification systems for osteochondritis dissecans (OCD) of the knee grade severity of disease by identifying certain lesion characteristics. The most widely used are the Hefti and Nelson systems. A novel classification presents a simpler 3-group approach to diagnose knee OCD by magnetic resonance imaging (MRI), compared with the Hefti (5-group) and Nelson (4-group) classifications. The purpose of this study was to compare the reliability of this novel classification with that of the more complex, established systems-an initial step in establishing validity and clinical utility. METHODS: In total, 120 standardized knee MRIs of patients with established knee OCD were preselected to capture the spectrum of lesion types, with regard to both progression and location of the lesion. Each of the MRIs were independently classified by 2 readers into the novel, Hefti, and Nelson classification systems. A random sample was rereviewed by 1 rater 6 weeks after initial review. The inter-rater and intrarater agreements were evaluated by estimating Krippendorff α. RESULTS: In total, 106 knees were classified by the novel, Hefti, and Nelson classification systems, as 14 of the knees lacked the necessary MRI sequences. There were no differences in inter-rater and intrarater agreement across classification systems. Krippendorff α for inter-rater agreement was 0.51 (95% confidence interval, 0.33-0.66) for the Hefti classification, 0.50 (0.34-0.64) for the Nelson classification, and 0.49 (0.32-0.65) for the novel classification. The intrarater agreement was 0.88 (0.75-0.97) for the Hefti classification, 0.94 (0.86-0.99) for the Nelson classification, and 0.98 (0.94-1.00) for the novel classification system. CONCLUSIONS: The novel classification for knee OCD demonstrated near-perfect intrarater agreement and moderate inter-rater agreement, consistent with the current, well-established classification systems. Pending a subsequent study on validity and clinical utility, this simpler classification system may offer an alternative, noninvasive diagnostic method to guide clinical treatment.

BACKGROUND: Medial discoid meniscus (MDM) is an exceedingly rare anatomic abnormality that presents similarly to other meniscal pathologies. Symptomatic MDM is typically managed arthroscopically with mixed short-term and long-term outcomes, although the existing knowledge about MDM is limited. The purpose of this study was to describe the presentation and surgical treatment of MDM in pediatric and adolescent patients. METHODS: Medical records of 12 knees with MDM in 8 pediatric and adolescent patients treated between 1991 and 2016 were reviewed retrospectively for patient characteristics, clinical manifestations, radiographic findings, operative techniques, and surgical outcomes. RESULTS: Of the 446 knees diagnosed arthroscopically with discoid menisci, lateral discoid meniscus was noted in 434 knees (97.3%) and MDM was present in 12 knees (2.7%). The MDM series included 8 patients of mean age 13.8 years (range: 7.8 to 19.8), of which 5 were males (63%), and 4 (50%) had bilateral involvement. Of the 11 knees with available clinical records, all cases presented symptomatically (pain, mechanical symptoms); 10 (91%) had concurrent physical exam findings. On intraoperative examination, discoid morphologies were described as complete in 4/8 knees (50%) or incomplete in 4/8 (50%), with associated instability in 6/12 (50%). Meniscal tears were reported in 9 cases (75%)-primarily, horizontal cleavage tears. Saucerization was performed in 11 knees (92%), with medial meniscal repair in 7 (58%), when indicated. Retear of the medial meniscus occurred in 4/11 knees (36%) at a mean of 25.8 months postoperation; 2 knees required revisions. One knee developed arthrofibrosis and underwent arthroscopic lysis of adhesions. CONCLUSIONS: MDM is a rare diagnosis, representing 3% of all discoid menisci, with a nonspecific clinical manifestation. Operative management of symptomatic MDM typically involves saucerization and meniscal repair, when indicated, for concurrent tears. Symptom resolution is common short-term, but long-term outcomes include recurrent meniscal tears. Subsequent observational studies are important to evaluate long-term outcomes, such as arthritic changes, with the advancement of arthroscopic techniques for meniscal preservation. LEVEL OF EVIDENCE: Level IV-retrospective case series.

BACKGROUND: Discoid meniscus is a congenital variant, typically involving the lateral meniscus, that comprises a spectrum of meniscal shapes and degrees of instability in an estimated 1% to 15% of the population. The purpose of this study was to describe the clinical and operative course of a large cohort of children and adolescents patients with symptomatic lateral discoid meniscus. METHODS: Medical records of 470 knees with symptomatic lateral discoid meniscus in 401 patients ages 18 years or younger diagnosed at a single institution between 1991 and 2016 were reviewed retrospectively for patient characteristics, treatment course (nonoperative and/or operative), and complications. Surgical reports were reviewed in the operative group. RESULTS: The series included 401 patients of mean age 11.6 years (range: 1 mo-18.9 y), of which 222 (55%) were female, and 69 (17%) had bilateral involvement. Of 470 knees, 83 (18%) were initially managed nonoperatively. Of these, 32 knees (39%) failed nonoperative management and were converted to surgical treatment at a median of 7.9 months (interquartile range: 4.0-15.1). In total, 419 knees were managed surgically with saucerization (partial meniscectomy) with or without meniscal repair/stabilization; 84 knees (20%) required at least one concurrent nonmeniscal procedure. Discoid meniscus tears were reported in 264/419 knees (63%) intraoperatively; horizontal cleavage tears were most common. Reoperation was required for 66/379 cases (17%) with clinical follow-up, at a median of 19.6 months (range: 9.2-34.9) after index saucerization; 60/379 cases (16%) had ongoing pain and/or mechanical symptoms at final follow-up. CONCLUSION: With a failure rate of 39% (32/83 knees), nonoperative management for discoid lateral meniscus frequently convert to surgical treatment. During surgery, meniscus tearing and instability are common and should be anticipated. Postoperatively, 33% (126/379) of knees with clinical follow-up underwent either reoperation, or had ongoing symptoms of the knee at final follow-up. Discoid mensical retear is the most common complication (94%, 62/66) prompting repeat surgery, and should be discussed with families before the index operation. LEVEL OF EVIDENCE: Level IV-descriptive case series.

BACKGROUND: Given that patient-reported outcome measures (PROMs) are increasingly used to inform clinical decision-making, it is vital that they are validated, reliable, responsive, and appropriate for the population under study. The purpose of this systematic review was to assess the rate of PROM use in the pediatric orthopaedic literature, characterize whether each use was in the PROM-validated demographic, and analyze the association between bibliometric factors and the use of PROMs with incomplete validation. METHODS: The Institute for Scientific Information (ISI) Web of Science database was queried for all clinical pediatric orthopaedic studies from 2014 to 2017. All PROMs were recorded for each study independently by 2 reviewers and cross-referenced with the published orthopaedic literature as of 2017 to determine if the PROM had been validated for the study population. PROMs that had not been validated, had been shown to be invalid, or had conflicting validity studies for use in the population of interest were designated as incompletely validated or used without complete validation. The following covariates were recorded for each study: subspecialty, inclusion of a statistician coauthor, sample size, journal, and the journal impact factor. χ analysis was used to evaluate the association between categorical variables and the use of at least 1 incompletely validated PROM. RESULTS: In total, 1000 articles were screened, yielding 653 studies that met our inclusion criteria. A total of 104/653 (16%) publications-reported PROMs. PROMs were used without complete validation 120/165 (73%) times, and 77/104 (74%) studies used at least 1 PROM without complete validation. The most frequent reasons for incomplete validation were (1) using PROMs that had been validated in adults, but not pediatrics (n=47; 28.5%), and (2) using PROMs that had been designated in the literature as invalid for pediatrics (n=27; 16.4%). The incomplete validation of at least 1 PROM was associated with smaller sample size (P=0.01) and subspecialty (P<0.01). Overall rates of PROM use and the proportion of PROMs used without complete validation were both found to be higher than those previously reported. CONCLUSION: The majority of pediatric orthopaedic studies reporting PROMs used at least 1 PROM without complete validation for their study population. LEVEL OF EVIDENCE: Level IV-systematic review of level I, II, III, and IV studies.

BACKGROUND: Discoid meniscus is a congenital variant typically affecting the lateral meniscus of the knee. Historically, surgical intervention when symptomatic consisted of total meniscectomy; however, after degenerative changes were observed, current treatments now focus on rim preservation with arthroscopic saucerization and meniscal repair for instability, when indicated. The purpose of our study was to examine long-term patient-reported outcomes of lateral discoid meniscus (LDM) treated with meniscal-preserving techniques. METHODS: Ninety-eight patients treated arthroscopically for LDM at a single institution at a minimum of 15 years ago were retrospectively identified and contacted by mailers and telephone to participate. Subjective functional outcomes and patient satisfaction data were collected using a questionnaire that included the validated International Knee Documentation Committee Subjective Knee Evaluation Form, Lysholm Score, Marx Activity Rating Scale, Tegner Activity Score, and Western Ontario and McMaster University Osteoarthritis Index Osteoarthritis Index. Patient and surgical characteristics and patient-reported outcomes were summarized by mean and SD, median and interquartile range (interquartile range), or frequency and percent, as appropriate. RESULTS: Of the 46 patients contacted (response rate of 46/98 eligible), 25 (54%) completed the questionnaires. The mean (±SD) age at initial surgery was 10.8 (±3.4) and 30.3 (±3.7) years at final follow-up. The mean (±SD) follow-up time from initial surgery was 19.5 (±2.8) years (range, 16 to 27). Patient-reported outcomes included: International Knee Documentation Committee 77.4±17.2, Lysholm 78.6±21, Western Ontario and McMaster University Osteoarthritis Index 7.6±11.3, Tegner Activity 7 (of 10), and Marx Activity Rating Scale 8 (of 10). Eleven (44%) cases underwent subsequent LDM-related surgery on the ipsilateral knee(s). There were no cases of total knee replacement. CONCLUSIONS: Overall, patient-reported outcomes were favorable at a minimum of 15-year follow-up after rim-preserving saucerization of LDM. While two thirds of patients were satisfied with their surgical outcomes, nearly half of patients underwent revision saucerization with or without meniscal repair. Subsequent long-term follow-up studies with objective outcome measures are important to further elucidate the natural history of LDM and understand how rim-preserving procedures may prevent the development of degenerative processes. LEVEL OF EVIDENCE: Level IV-case series, prognostic study.

Hip arthroscopists and the surgical team should be aware of the potential complication of intra-abdominal fluid extravasation (IAFE). Fluid extravasation may be relatively common. Fortunately, symptomatic IAFE remains rare but can be serious. Increased peak inspiratory pressure (PIP) should be a parameter that we follow and discuss with our anesthesia colleagues. This would be an excellent point to bring up during the mandatory preoperative time out. Increased PIP or hemodynamic instability should warrant a consideration of IAFE.

BACKGROUND: Observational studies are the most commonly used study designs in the pediatric orthopaedic literature. The differences between observational study designs are important but not widely understood, leading to potential discrepancies between the reported and actual study design. Study design misclassification is associated with a potential for misreporting level of evidence (LOE). The purpose of this study was to determine the degree of study design and LOE misclassification in the pediatric orthopaedic literature. METHODS: The Institute for Scientific Information (ISI) Web of Science was queried to identify all pediatric orthopaedic observational studies published from 2014 to 2017. Reported study design and LOE were recorded for each study. The actual study design and LOE were determined on the basis of established clinical epidemiological criteria by reviewers with advanced epidemiological training. Studies with a discrepancy between reported versus actual study design and LOE were identified. The following covariates were recorded for each study: subspecialty, inclusion of a statistician coauthor, sample size, journal, and journal impact factor. χ test was used to identify factors associated with study design and LOE misreporting. RESULTS: In total, 1000 articles were screened, yielding 647 observational studies. A total of 335 publications (52%) did not clearly report a study design in the abstract or manuscript text. Of those that did, 59/312 (19%) reported the incorrect study design. The largest discrepancy was in the 109 studies that were reported to be case series, among which 30 (27.5%) were actually retrospective cohort studies. In total, 313 publications (48%) did not report a LOE. Of those that did, 95/334 (28%) reported the incorrect LOE. In total, 33 studies (19%) reported a LOE that was higher than the actual LOE and 62 (35%) under-reported the LOE. CONCLUSIONS: The majority of observational pediatric orthopaedic studies did not report a study design or reported the wrong study design. Similarly, the majority of studies did not report or misreported their LOE. Greater epidemiological rigor in evaluating observational studies is required on the part of investigators, reviewers, and editors. LEVEL OF EVIDENCE: Level II.

BACKGROUND: Revision anterior cruciate ligament (ACL) reconstruction in pediatric patients has not been well studied. The purpose of this study was to assess the demographics, technique, and results of ACL revision surgery in children and adolescents. METHODS: This was a retrospective case series with outcomes assessment of patients 18 years old and younger who underwent revision ACL surgery over a 16-year period at a single institution. Medical records were reviewed for demographics, clinical and operative data, and patients were contacted for outcomes at a minimum of 1 year after revision surgery. RESULTS: Ninety revision ACL reconstructions were performed by 7 surgeons in 88 patients (44 male, 44 female). Average patient age at the time of revision was 16.6 years (SD, 1.7), and 28.8% of patients were skeletally immature. Time to failure after primary ACL reconstruction was 1.28 years (SD, 1.1) and revision surgery was performed 1.56 years (SD, 1) after the index procedure. Revision graft type included allograft (61.1%), patellar tendon (21.1%), hamstring (16.7%), and iliotibial band (1.1%). There was a 20% graft reinjury rate. Subsequent surgical procedures after revision were required in 25.5% of knees. Twenty percent of revision reconstructions had contralateral ACL injuries, and this percentage was higher (33%) among those who went on to injure their revision graft. Median outcome scores collected from 44 patients (50%) at a mean of 5.1 years following surgery (SD, 3.4) were: Pedi-IKDC 79.9, Lysholm 84.5, and Tegner 9.0. Sixty-nine percent of patients reported returning to sports, however, only 55.2% of these reported being able to return to the same level of play. CONCLUSIONS: Revision ACL reconstruction in pediatric patients was associated with suboptimal patient-reported outcomes, high complication rates, relatively high graft retear rates, high risk of contralateral ACL injury, and compromised return to sports rates. LEVEL OF EVIDENCE: Level IV.

BACKGROUND: Missed posterolateral corner (PLC) injuries are a known cause of anterior cruciate ligament reconstruction (ACL) failure in the adult population. Failed ACL reconstruction causes significant morbidity in the skeletally immature pediatric population. There is little literature on the character and potential significance of PLC injuries in skeletally immature patients. METHODS: Magnetic resonance imaging studies of the knee at a tertiary care children's hospital for patients who underwent an ACL reconstruction without PLC surgery were retrospectively reviewed. Demographic variables were obtained through chart review, and magnetic resonance imaging studies were evaluated for PLC (popliteus, fibular collateral ligament, popliteofibular ligament, and arcuate ligament) injury, and ACL, medial collateral ligament (MCL), bone bruise, fracture, and meniscal pathology by an experienced pediatric musculoskeletal radiologist. RESULTS: A total of 50 patients with a mean age at 13.3 years at injury were analyzed. PLC injuries were found in 26 patients (52%), with 7 patients (14%) having a complete tear of a component of the PLC. There was no association between sex (P=0.35), Segond fracture (P=0.09), meniscus injury (P=0.92), or MCL injury (P=0.24) with the risk of PLC injury. There was an association between patient age and PLC injury (P=0.02). For each additional year of age, the odds of PLC injury increased by 1.8 times (odds ratio, 1.8; 95% confidence interval, 1.4-2.2). There was no association between PLC injury and ACL graft failure (P=0.19). CONCLUSIONS: Missed PLC injuries are a significant source of morbidity and poor clinical outcomes in the management of concomitant ACL injuries in adults. This study demonstrates the prevalence of PLC injuries in the setting of concomitant ACL injuries in the unique skeletally immature patient population. Incomplete PLC injuries are relatively common. Complete PLC injuries are relatively uncommon. PLC injury was more common in older patients. No other concomitant injury predicted the likelihood of PLC injury. Further research is needed regarding the risk of ACL reconstruction failure from associated PLC injury and the indications for PLC reconstruction in skeletally immature patients. LEVEL OF EVIDENCE: Level IV-diagnostic study.

CONTEXT: To treat anterior cruciate ligament (ACL) injury, ACL reconstruction (ACLR) surgery is currently a standard of the care. However, effect of graft type including bone-patellar tendon-bone (BTB), hamstring tendon, or iliotibial band (ITB) on thigh size, knee range of motion (ROM), and muscle strength are understudied. OBJECTIVE: To compare postoperative thigh circumference, knee ROM, and hip and thigh muscle strength in adolescent males who underwent ACLR, based on the 3 different autograft types: BTB, hamstring (HS), and ITB. SETTING: Biomechanical laboratory. PARTICIPANTS: Male ACLR patients who are younger than 22 years of age (total N = 164). INTERVENTION: At 6- to 9-month postoperative visits, thigh circumference, knee ROM, and hip and thigh muscle strength were measured. MAIN OUTCOME MEASURES: Deficits of each variable between the uninvolved and ACLR limb were compared for pediatric and adolescent ACLR males in the BTB, HS, and ITB cohorts. Baseline characteristics, including physical demographics and meniscus tear status, were compared, and differences identified were treated as covariates and incorporated in analysis of covariance. RESULTS: Data were from 164 adolescent male ACLR patients [mean age 15.7 (1.2) years]. There were no statistical differences in thigh circumference, knee ROM, hip abductor, and hip-extensor strength among the 3 autografts. However, patients with BTB demonstrated 12.2% deficits in quadriceps strength compared with 0.5% surplus in HS patients (P = .002) and 1.2% deficits in ITB patients (P = .03). Patients with HS showed 31.7% deficits in hamstring strength compared with 5.4% deficits in BTB (P = .001) and 7.7% deficits in ITB (P = .001) groups at 6- to 9-month postoperative visits. CONCLUSION: Adolescent male ACLR patients with BTB and HS autografts demonstrated significant deficits in quadriceps and hamstring strength, respectively, at 6 to 9 months postoperatively. Minimal lower-extremity strength deficits were demonstrated in pediatric male ACLR patients undergoing ITB harvest.
