Identifying and addressing health-related social needs: a Medicaid member perspective.

BACKGROUND: Multiple state and national health care organizations have invested in activities to screen for and address the health-related social needs (HRSNs) of their patients. However, patient perspectives concerning HRSN screening discussions and facilitated referrals to supports are largely unexplored. The main objectives of this study were to explore the ways in which Massachusetts Medicaid (MassHealth) members engage with their health care clinicians to discuss HRSNs, to identify common needs discussed, and to describe whether members feel these needs are being addressed by health care clinicians and staff. METHODS: The study team performed a cross-sectional, qualitative research study that included in-depth, open-ended interviews with 44 adult MassHealth members. Interviews were conducted between June and October 2022. Interviews were recorded, transcribed, and systematically coded for analysis, and common themes were reported. The data collected for this study were part of a larger independent evaluation of MassHealth's 2017-2022 Section 1115 Demonstration that granted authority from CMS to implement health care delivery system reforms in Massachusetts. RESULTS: In this qualitative study of Medicaid members, some reportedly felt comfortable freely discussing all of their clinical and social needs with their health care clinicians, while others noted feelings of apprehension. Several members recalled being asked about their HRSNs in various clinical or community settings, while others did not. The majority of members endorsed having an unmet HRSN, including housing, nutrition, financial, or transportation issues, and many barriers to addressing these HRSNs were discussed. Finally, many members cited a preference for discussing HRSNs with community-based care coordinators and social workers at the community partner organizations rather than with their health care clinicians. Community-based care coordinators were lauded as essential facilitators in making the connection to necessary resources to help address HRSNs. CONCLUSIONS: Study results highlight an opportunity to increase the effectiveness of HRSN screening and referral practices within the health care setting through relationship building between Medicaid members and diverse interdisciplinary care teams that include staff such as community health workers. Continued investment in cross-sector partnerships, screening workflows, and patient-clinician relationships may contribute to establishing an environment in which members can comfortably discuss HRSNs and connect with needed services to improve their health.

The Use of Psychological Patient Reported Outcome Measures to Identify Adolescent Athletes at Risk for Prolonged Recovery Following an ACL Reconstruction.

BACKGROUND: Psychological response to injury and the recovery process impact return to play and can put an athlete at risk for prolonged recovery. The purpose of this study was to investigate the psychological changes that occur surrounding an anterior cruciate ligament (ACL) reconstruction utilizing a set of patient reported outcomes measures (PROMs) that focus on psychological factors. METHODS: Consecutive patients undergoing a primary ACL reconstruction, ages 12 to 18, were recruited. Patients were included if they verbalized a desire to return to the same sport and a baseline Tegner of >6. Functional and psychological PROMs were administered preoperatively, 6 months, and 1 year postoperatively. A Y-Balance Test was utilized to assess for clearance. RESULTS: Of the 68 participants, 36 were female (52.9%) and 32 male, with a mean age of 14.5 years. On average, participants were cleared to return to sport 259.1 days postoperatively. Of the measures given preoperatively, only the Athletic Coping Skills Inventory-28 (ACSI)-28 correlated with delayed recovery time (rs=-0.291, P=0.04). Lower baseline ACSI-28 subscale scores in coachability (rs=-0.298, P=0.03) and Coping with Adversity (rs=-0.341, P=0.01) were correlated with delayed recovery. Participants that took longer than average to recover scored significantly lower on the ACSI-28 preoperatively than those with a shorter recovery time (62.04 vs. 54.8, P<0.01). Participants that scored <58 on their preoperative ACSI-28 took 2 months longer to recover than participants who scored ≥58 (9.6 vs. 7.65 mo, P<0.01). At 6 months postoperatively, higher ACSI-28 subscale Concentration (rs=-0.357, P<0.01) and Peaking Under Pressure (rs=-0.274, P=0.04) scores correlated with shorter recovery time. CONCLUSIONS: The ACSI-28 significantly correlated with recovery time following ACL reconstruction. A baseline score of 58 may be a valuable cutoff to identify youth athletes at risk for prolonged recovery. LEVEL OF EVIDENCE: Level II-prospective study.

Is Anteromedial Drilling Safe in Transphyseal Anterior Cruciate Ligament Reconstruction in Adolescents with Growth Remaining?

BACKGROUND: Previous reports of transphyseal drilling in anterior cruciate ligament (ACL) reconstruction have demonstrated good clinical outcomes without subjective changes in further skeletal development. The purpose of this study is to evaluate radiographic changes during continued growth following a transphyseal ACL reconstruction using an anteromedial femoral (AM) drilling technique in patients with >18 months of growth remaining. METHODS: A review of consecutive adolescents who underwent a soft tissue transphyseal ACL reconstruction using an AM drilling technique was performed. Inclusion criteria was 18 months of growth remaining based on radiographic bone age and standing radiographs at least one year from the index procedure. Demographic, preoperative, and postoperative data, and follow-up three-foot standing lower extremity radiographs were reviewed. Radiographic data included femoral length, tibial length, total lower extremity length, mechanical axis deviation (MAD), lateral distal femoral angle (LDFA), and medial proximal tibial angle (MPTA). RESULTS: In total 12 adolescent patients with a mean age of 13.4 years (range, 12.3 to 14.4) and bone age of 13.4 years (11.5 to 14) at the time of surgery were included. At an average of 2.27-year follow-up (412 to 1058 d), there was no difference in the total growth of the operative and nonoperative limb (48.5 mm vs. 47 mm; P=0.36). In addition, the average increases in femoral length (23.4 mm) and tibial length (25.8 mm) were not statistically different between the operative and the nonoperative limb (P=0.12; P=0.75). There was no statistical difference in mechanical axis deviation, LDFA, or MPTA between preoperative and postoperative radiographs. Mean differences in operative and nonoperative coronal angular changes were all <1.5 degrees. CONCLUSIONS: With at least 2 years of growth remaining, transphyseal ACL reconstruction with anteromedial drilling did not significantly affect the physis or residual growth compared with the contralateral extremity. Although this technique may create a larger defect in the physis, standing radiographs demonstrate there is no change in limb length or angulation in growing adolescents approximately 2 years after surgery. LEVEL OF EVIDENCE: This is a case series; Level IV evidence.

Intraobserver and Interobserver Measurement Variability of the Rib-Vertebral Angle Difference.

BACKGROUND: The rib-vertebral angle (RVAD) differentiates between progressive and resolving infantile idiopathic scoliosis (IIS) curves. Those with a RVAD<20 degrees often resolve without treatment, whereas those >20 degrees often progress and require treatment. The mathematical magnitude of RVAD measurement variability has not been described, and was thus the purpose of this study. It is important to know the reliability of RVAD measurements so as to understand changes that can be attributed to observer error alone. PURPOSE: The purpose of the study was to mathematically determine the intraobserver and interobserver measurement variability of the RVAD difference in IIS. METHODS: A convenience sample of 50 patients with IIS was selected. The RVAD was measured twice by 7 different observers separated by a minimum of 3 weeks. The 7 different readers chosen to measure the RVAD were 2 orthopaedic residents, 1 pediatric radiologist, and 4 attending pediatric orthopaedic surgeons. The same goniometer was used for all measurements. Intraobserver and interobserver measurement variability was determined using 3 well known used statistical methods. RESULTS: The 3 different methods used to determine intraobserver and interobserver variability using 95% prediction/confidence limits gave very similar results. Intraobserver variability was ∼24 degrees and the interobserver variability was ∼23 degrees. DISCUSSION: The utility of the RVAD in medical decision-making and counseling of patients with IIS should be approached with caution when used in isolation due to the large measurement variability. LEVEL OF EVIDENCE: Level 3.

Fractures from trampolines: results from a national database, 2002 to 2011.

BACKGROUND: No study specifically analyzes trampoline fracture patterns across a large population. The purpose of this study was to determine such patterns. METHODS: We queried the National Electronic Injury Surveillance System database for trampoline injuries between 2002 and 2011, and the patients were analyzed by age, sex, race, anatomic location of the injury, geographical location of the injury, and disposition from the emergency department (ED). Statistical analyses were performed with SUDAAN 10 software. Estimated expenses were determined using 2010 data. RESULTS: There were an estimated 1,002,735 ED visits for trampoline-related injuries; 288,876 (29.0%) sustained fractures. The average age for those with fractures was 9.5 years; 92.7% were aged 16 years or younger; 51.7% were male, 95.1% occurred at home, and 9.9% were admitted. The fractures were located in the upper extremity (59.9%), lower extremity (35.7%), and axial skeleton (spine, skull/face, rib/sternum) (4.4%-spine 1.0%, skull/face 2.9%, rib/sternum 0.5%). Those in the axial skeleton were older (16.5 y) than the upper extremity (8.7 y) or lower extremity (10.0 y) (P<0.0001) and more frequently male (67.9%). Lower extremity fractures were more frequently female (54.0%) (P<0.0001). The forearm (37%) and elbow (19%) were most common in the upper extremity; elbow fractures were most frequently admitted (20.0%). The tibia/fibula (39.5%) and ankle (31.5%) were most common in the lower extremity; femur fractures were most frequently admitted (57.9%). Cervical (36.4%) and lumbar (24.7%) were most common locations in the spine; cervical fractures were the most frequently admitted (75.6%). The total ED expense for all trampoline injuries over this 10-year period was $1.002 billion and $408 million for fractures. CONCLUSIONS: Trampoline fractures most frequently involve the upper extremity followed by the lower extremity, >90% occur in children. The financial burden to society is large. Further efforts for prevention are needed.

Changes in Health Care Utilization During the First 2 Years of Massachusetts Medicaid Accountable Care Organizations.

On March 1, 2018, the Massachusetts Medicaid and Children's Health Insurance Program (MassHealth) launched an ambitious accountable care organization (ACO) program that sought to integrate care across the physical, behavioral, functional, and social services continuum while holding ACOs accountable for cost and quality. The study objective was to describe changes in health care utilization among MassHealth members during the pre-ACO baseline (2015-2017) and post-implementation periods (2018 and 2019). Using MassHealth administrative data, the authors conducted a repeated cross-sectional study of MassHealth members enrolled in ACOs during 2015-2019. Rates of primary care visits, all-cause and primary-care sensitive emergency department (ED) visits, ED boarding, hospitalizations, acute unplanned admissions, and readmissions were reported during the baseline period (2015-2017) and year 1 (2018) and year 2 (2019). Primary care visit rates increased for adult members throughout the study period from a baseline mean of 7.2-9.2 per member per year (observed-to-expected [O:E]: 1.16) in 2019. Observed all-cause hospitalization rates fell below expected values with O:E ratios of 0.96 among adults and 0.79 among children in 2018, and 0.96 and 0.92 among adults and children, respectively, in 2019. All-cause ED visit rates increased slightly, and rates of pediatric asthma-related admissions, unplanned admissions for adults with ambulatory care sensitive conditions, and unplanned admissions and ED boarding for adults with substance use disorder and serious mental illness all declined for the study period. These findings are suggestive of utilization shifts to higher-value, lower-cost care under Massachusetts's innovative and comprehensive ACO model.

The role of primary care providers in testing for sexually transmitted infections in the MassHealth Medicaid program.

The objective of this study was to determine the prevalence and predictors of testing for sexually transmitted infections (STIs) under an accountable care model of health care delivery. Data sources were claims and encounter records from the Massachusetts Medicaid and Children's Health Insurance Program (MassHealth) for enrollees aged 13 to 64 years in 2019. This cross-sectional study examines the one-year prevalence of STI testing and evaluates social determinants of health and other patient characteristics as predictors of such testing in both primary care and other settings. We identified visits with STI testing using procedure codes and primary care settings from provider code types. Among 740,417 members, 55% were female, 11% were homeless or unstably housed, and 15% had some level of disability. While the prevalence of testing in any setting was 20% (N = 151,428), only 57,215 members had testing performed in a primary care setting, resulting in an 8% prevalence of testing by primary care clinicians (PCCs). Members enrolled in a managed care organization (MCO) were significantly less likely to be tested by a primary care provider than those enrolled in accountable care organization (ACO) plans that have specific incentives for primary care practices to coordinate care. Enrollees in a Primary Care ACO had the highest rates of STI testing, both overall and by primary care providers. Massachusetts' ACO delivery systems may be able to help practices increase STI screening with explicit incentives for STI testing in primary care settings.

Paying for Medical and Social Complexity in Massachusetts Medicaid.

Importance: The first MassHealth Social Determinants of Health payment model boosted payments for groups with unstable housing and those living in socioeconomically stressed neighborhoods. Improvements were designed to address previously mispriced subgroups and promote equitable payments to MassHealth accountable care organizations (ACOs). Objective: To develop a model that ensures payments largely follow observed costs for members with complex health and/or social risks. Design, Setting, and Participants: This cross sectional study used administrative data for members of the Massachusetts Medicaid program MassHealth in 2016 or 2017. Participants included members who were eligible for MassHealth's managed care, aged 0 to 64 years, and enrolled for at least 183 days in 2017. A new total cost of care model was developed and its performance compared with 2 earlier models. All models were fit to 2017 data (most recent available) and validated on 2016 data. Analyses were begun in February 2019 and completed in January 2023. Exposures: Model 1 used age-sex categories, a diagnosis-based morbidity relative risk score (RRS), disability, serious mental illness, substance use disorder, housing problems, and neighborhood stress. Model 2 added an interaction for unstable housing with RRS. Model 3 added rurality and updated diagnosis-based RRS, medication-based RRS, and interactions between sociodemographic characteristics and morbidity. Main Outcome and Measures: Total 2017 annual cost was modeled and overall model performance (R2) and fair pricing of subgroups evaluated using observed-to-expected (O:E) ratios. Results: Among 1 323 424 members, mean (SD) age was 26.4 (17.9) years, 53.4% were female (46.6% male), and mean (SD) 2017 cost was $5862 ($15 417). The R2 for models 1, 2, and 3 was 52.1%, 51.5%, and 60.3%, respectively. Earlier models overestimated costs for members without behavioral health conditions (O:E ratios 0.94 and 0.93 for models 1 and 2, respectively) and underestimated costs for those with behavioral health conditions (O:E ratio >1.10); model 3 O:E ratios were near 1.00. Model 3 was better calibrated for members with housing problems, those with children, and those with high morbidity scores. It reduced underpayments to ACOs whose members had high medical and social complexity. Absolute and relative model performance were similar in 2016 data. Conclusions and Relevance: In this cross-sectional study of data from Massachusetts Medicaid, careful modeling of social and medical risk improved model performance and mitigated underpayments to safety-net systems.

Treatment Variability and Complications Associated With Pediatric Lateral Ankle Injuries: A POSNA Quality, Safety, and Value Initiative Survey.

Background: Isolated pediatric lateral ankle injuries, including ankle sprain (AS) and nondisplaced Salter-Harris type 1 (SH-1) distal fibular fracture, are common orthopaedic sports-related injuries. Variability in treatment is suspected among pediatric orthopaedic surgeons. Complications from medical treatment or lack thereof have not been reported in this population. Purpose: The purpose of this study was to investigate treatment variability and associated complications after pediatric AS and SH-1 via a survey of members of the Pediatric Orthopaedic Society of North American (POSNA). Study Design: Cross-sectional study. Level of evidence, 5. Methods: A voluntary, anonymous survey was distributed to POSNA membership (approximately 1400 members) via email. Survey questions, specific to both grade 1 or 2 AS and nondisplaced or minimally displaced SH-1 injuries in skeletally immature patients, focused on initial evaluation, immobilization, return to sports, and complications. We analyzed variability both in treatment between AS and SH-1 injury and in respondent characteristics. For statistical analysis, chi-square or Fisher exact test was used for categorical variables, and analysis of variance was used for continuous variables. Results: The survey response rate was 16.4% (229/1400). Of the respondents, 27.7% used examination only to distinguish between AS and SH-1, whereas 18.7% performed serial radiography to aid with diagnosis. A controlled ankle motion boot or walking boot was the most common immobilization technique for both AS (46.3%) and SH-1 (55.6%); the second most common technique was bracing in AS (33.5%) and casting in SH-1 (34.7%). Approximately one-third of all respondents recommended either outpatient or home physical therapy for AS, whereas only 11.4% recommended physical therapy for SH-1 (P < .01). Results showed that 81.2% of respondents reported no complications for SH-1 treatment and 87.8% reported no complications for AS treatment. Cast complications were reported by 9.6% for SH-1 and 5.2% for AS. Rare SH-1 complications included distal fibular growth arrest, infection, nonunion, late fracture displacement, and recurrent fracture. Conclusion: Significant variability was found in primary treatment of pediatric AS and SH-1 injuries. Rare complications from injury, treatment, and neglected treatment after SH-1 and AS were reported.

A Pilot Randomized Controlled Trial of Docosahexaenoic Acid for the Treatment of Sport-Related Concussion in Adolescents.

The objective was to examine the use of docosahexaenoic acid (DHA) for the treatment of sport-related concussion (SRC) in adolescent athletes. We hypothesize that participants who intake 2 g of DHA daily will not experience differences in recovery compared with participants who take a placebo. This double-blind, randomized controlled pilot trial was performed in a tertiary pediatric sports medicine clinic from 2013 to 2017 in adolescents (14-18 years) presenting with diagnosed SRC within 4 days of injury. Forty participants were randomized into DHA or PLACEBO group and were instructed to take 2 capsules twice daily for 12 weeks. Participants in the DHA group were symptom-free earlier than the PLACEBO group (11.0 vs 16.0 days, P = .08) and were cleared to begin the Return to Sport progression (14.0 vs 19.5 days, P = .12) sooner. The use of 2 g/day of DHA was well-tolerated and did not significantly affect recovery times in adolescent athletes following SRC.Clinical Trial Registration: ClincalTrials.gov, NCT01903525.

Continued play following adolescent sport-related concussion: Prospective data from the North Texas Concussion Registry (ConTex).

Our study aims were to identify the frequency of continued play following sport-related concussion (SRC), defined as continuing athletic activity on the same day following a suspected SRC, characteristics associated with continued play, and whether continued play was associated with worse outcomes. A prospective study of participants ages 13-18 years diagnosed with SRC at a pediatric sports medicine clinic over a 4-year period was conducted. A comparison was performed between athletes who reported continued play following SRC (PLAY) and those who did not (NO PLAY). Of 441 participants, 231 (52.4%) were in the PLAY group. The PLAY group recalled less severe balance problems from the day of injury (p = 0.02), but reported greater symptoms of trouble falling asleep, concentrating, and remembering at their initial clinic visit (p < 0.05). There was no difference in recovery time between groups. Greater symptom severity score at the initial clinic visit and longer time to presentation were associated with prolonged recovery in both groups (p < 0.01). In conclusion, more than half of the athletes in this sample continued to play on the same day following SRC. Our results indicate the need for a heightened focus on education and additional efforts to reduce continued play following SRC in adolescents.

Investigating a key structural determinant of health, racism, and related social determinants of health in Massachusetts during the COVID-19 pandemic.

A disproportionate burden of the ongoing COVID-19 pandemic is being shouldered by members of racial and ethnic minorities and socially disadvantaged communities. Structural and social determinants of health have been recognized as key contributors to the inequalities observed. Racism, a major structural determinant of health that patterns related social determinants of health, in the USA, warrants further investigation. In this perspective piece we provide an overview of the historical context of racism, followed by preliminary findings from the ongoing COVIDStory study-a cross-sectional study addressing perceptions of COVID-19 and COVID-19 research-that highlights the experiences of non-Hispanic Black and Hispanic identifying adult participants, residing in Worcester Massachusetts, during the COVID-19 pandemic. We then discuss these findings in the context of current and past research considering racism and relevant social determinants of health. Our study results suggest that racism and its residuals (residential segregation, economic insecurity, discrimination, bias, and vigilance) are modern challenges for non-Hispanic Black and Hispanic participants, and these findings are supported by the existing literature. It is our hope that this perspective piece provides additional evidence for action on structural and social determinants affecting the health of minoritized people, especially those living in Massachusetts.

Continued Play Following Sport-Related Concussion in United States Youth Soccer.

Medical guidelines and legislation in the US call for immediate removal from play and prohibit continued play on the same day if a concussion is suspected. However, there is limited literature examining whether these guidelines and laws are being followed in youth soccer. The purpose of this study was to identify the frequency at which youth soccer players continued play on the same day following sport-related concussion and factors that may be associated with this behavior. A retrospective review of youth soccer players diagnosed at the initial clinic visit with a sport-related concussion was performed. Participants were categorized into groups, those who continued play on the same day as their concussion (PLAY) and those who did not (NO PLAY). Records were reviewed for demographics, injury characteristics, SCAT3™ symptoms, mBESS and ImPACT® results, symptom resolution and return to play protocol initiation. Fifty-eight girls (mean age: 14 years, range: 7-18 years) and 29 boys (mean age: 14.4 years, range: 6-18 years) participated in this study. Thirty of 58 girls (51.7%) continued play the same day compared to only 5 of 29 boys (17.2%; p=0.002). The odds of continued play in girls were 5 times as high as the odds of continued play in boys (OR=5.05; 95% CI, 1.59-19.3). Overall, 35 (40.2%) soccer players continued play on the same day following a concussion. In conclusion, approximately 40% of youth soccer players continued play on the same day as their concussion. Girl soccer players demonstrated a significantly higher frequency of continued play than boys.

Activity Measures in Pediatric Athletes: A Comparison of the Hospital for Special Surgery Pediatric Functional Activity Brief Scale and Tegner Activity Level Scale.

BACKGROUND: In young athletes, patient-reported activity level is frequently used to determine return to the same level of sport after treatment. PURPOSE: To evaluate the validity and score distributions of the Hospital for Special Surgery Pediatric Functional Activity Brief Scale (HSS Pedi-FABS) compared with the Tegner Activity Level Scale (Tegner) in pediatric athletes. STUDY DESIGN: Cohort study (Diagnosis); Level of evidence, 2. METHODS: A retrospective review of 517 consecutive youth athletes who came to a sports medicine specialty clinic for a knee evaluation was performed. Patients completed the HSS Pedi-FABS, Tegner, and a sports participation survey before evaluation. Scores were compared with reported hours, days, and weeks of participation in sports as well as level of competition. Floor or ceiling effects were identified, and finally, the means and distributions of scores in the 8 most common primary sports were analyzed. RESULTS: A total of 398 participants (54.0% female) with an average age of 14.5 years (range, 10.0-18.8 years) were included in the study. The HSS Pedi-FABS demonstrated correlations with hours per week (r = 0.302; P < .001), days per week (r = 0.278; P < .001), and weeks per year (r = 0.136; P = .014) playing a primary sport. The Tegner only demonstrated a correlation with days per week (r = 0.211; P = .001). Additionally, club/select-level athletes scored higher than junior high/high school-level athletes on the HSS Pedi-FABS (23.8 vs 21.0; P = .004), but no difference was observed with the Tegner. No floor or ceiling effect was observed for the HSS Pedi-FABS, but a ceiling effect was present for the Tegner (32.8%). The HSS Pedi-FABS demonstrated a varied score distribution between the 8 most common primary sports (P < .001), with soccer players scoring the highest, on average (23.5). CONCLUSION: The HSS Pedi-FABS, compared with the Tegner, demonstrated more correlations with an athlete's participation in sport with no floor or ceiling effect and had a wide distribution of scores even among same-sport athletes. The HSS Pedi-FABS may be a more valuable activity measure than the Tegner in pediatric athletes.

Concurrent Bilateral Anterior Tibial Stress Fractures and Vitamin D Deficiency in an Adolescent Female Athlete: Treatment With Early Surgical Intervention.

Case: A 16-year-old African American multi-sport female athlete presents with bilateral worsening activity-related leg pain for 5 months. Multiple bilateral anterior tibial diaphyseal stress fractures and significant vitamin D deficiency were identified. She was treated with a combination of vitamin D supplements and static intramedullary nailing of the bilateral tibias resulting in clinical and radiographic healing and return to sports. Discussion: Vitamin D deficiency and high level of activity in a young athlete may be the etiology to atypical multiple stress fractures. In athletes who may want to return to sport rapidly, early operative intervention and correction of vitamin D deficiency may be treatment options. Level of Evidence: Level V- case report.

Combined Transphyseal and Lateral Extra-articular Pediatric Anterior Cruciate Ligament Reconstruction: A Novel Technique to Reduce ACL Reinjury While Allowing for Growth.

BACKGROUND: Treatment of anterior cruciate ligament (ACL) injuries in the adolescent population continues to be complicated by an unacceptably high rate of secondary ACL injury. PURPOSE: To describe the failure rate and outcomes after a hybrid pediatric ACL reconstruction (ACLR) employing transphyseal hamstring (TPH) autograft combined with an extra-articular technique using an iliotibial band (ITB) autograft. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Consecutive patients undergoing combined TPH-ITB ACLR between January 2012 and April 2017 with a minimum 2-year follow-up were reviewed. With the goal of decreasing ACL graft injury in this high-risk group, this technique employed anteromedial portal drilling for TPH with an extraosseous femoral ITB technique and intra-articular TPH-ITB grafts fixed within the tibial bone tunnel. Demographics, bone age, standing alignment radiograph for growth and mechanical axis grade, return to sport, graft failure, and patient-reported outcome measures were analyzed. RESULTS: A total of 61 knees in 60 adolescents underwent the combined TPH-ITB ACLR, with 57 knees (93.4%) meeting inclusion criteria with a mean follow-up of 38.5 months (range, 24-78 months). Only 3 of 57 knees (5.3%) sustained ACL reinjury. The mean age was 13.0 years (range, 11-16 years) with 36 male patients (mean bone age, 14.2 years) and 21 female patients (mean bone age, 13.3 years), and 91% of patients (52 of 57) returned to sport. Participants demonstrated a high functional level at final follow-up, with a mean score of 91.2 (range, 46.7-100) on the Pediatric International Knee Documentation Committee (Pedi-IKDC) Subjective Knee Evaluation Form and mean score of 22.4 (range, 4-30) on the Pediatric Functional Activity Brief Scale (Pedi-FABS). To critically assess growth, a cohort with ≥18 months of growth remaining at surgery was evaluated at maturity. No difference was seen in mean operative and nonoperative leg growth (49.7 mm and 49.8 mm). Although no family reported cosmetic or functional alignment or length concerns, 1 of 18 (5.5%) had a final limb length discrepancy >10 mm (12 mm) and a perioperative alignment difference (0-Grade II valgus). CONCLUSION: Combined TPH-ITB ACLR in adolescents resulted in high activity levels (Pedi-FABS, 22.4; median, 25) and a low (5.3%) graft failure rate at a mean 38.5 months.

The Importance of a Standardized Screening Tool to Identify Thromboembolic Risk Factors in Pediatric Lower Extremity Arthroscopy Patients.

INTRODUCTION: Deep vein thrombosis and pulmonary embolism are major complications that can occur in common orthopaedic procedures such as knee arthroscopy. The purpose of this study is to determine the incidence of venous thromboembolism (VTE) risk factors in adolescent patients undergoing elective lower extremity arthroscopy. A second objective is to determine whether a targeted, standardized screening tool is both cost- and clinically effective in the identification of VTE risk factors in adolescents. METHODS: A standardized VTE screening tool was prospectively administered to all elective arthroscopic procedures in a pediatric sports medicine practice. A comparison cohort that did not complete the screening tool was isolated through a retrospective chart review identifying VTE risk factors. The incidence and cost between the two cohorts were compared. RESULTS: Of 332 subjects who did not receive a targeted screening (TS) tool, 103 risk factors were noted. One pulmonary embolism case was identified with a total incidence of 0.15% over 3 years. With TS, we identified 325 subjects with 134 identifiable risk factors. Six patients (1.8%) were noted to be very high risk, requiring consultation with hematology. No VTEs were reported. When compared with the retrospective review, TS identified 30% more risk factors. A significant increase in the identification of family history of blood clots (P < 0.001), history of previous blood clot (P = 0.059), recurrent miscarriages in the family (P = 0.010), and smoking exposure (P = 0.062) was found. Additionally, the total cost of screening was less than the cost of prophylaxis treatment with no screening ($20.98 versus $23.51 per person, respectively). DISCUSSION: Risk factors for VTE may be present in 32.5% of elective adolescent arthroscopic patients. A TS model for VTE identified 30% more risk factors, especially a significant family history, and was shown to be a cost-effective way to safely implement a VTE prevention program. LEVEL OF EVIDENCE: Level II.

Incidence, Presentation, and Treatment of Pediatric and Adolescent Meniscal Root Injuries.

BACKGROUND: Despite the increasing incidence of sports-related knee injuries in youth athletes, few studies have reported on the diagnosis and treatment of pediatric and adolescent meniscal root injuries. PURPOSE: To describe traumatic posterior meniscal root injuries in a pediatric and adolescent population and compare the presentation of meniscal root injuries versus that of nonroot injuries. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: A study was conducted of all knee arthroscopies performed on consecutive patients treated in a pediatric sports practice from March 2012 through February 2015. All patients who were younger than 20 years at the time of their injury and who underwent an arthroscopy with meniscal injury were included. Patients with discoid lateral meniscus, atraumatic meniscal cysts, partial-thickness meniscal root injuries (LaPrade type 1), and recurrent root tears were excluded. A comparative analysis of root and nonroot injuries was performed. RESULTS: A total of 314 patients had surgery for meniscal injury (mean patient age, 16.0 years; range, 10.5-19.6 years). Of these patients, 58 (18.5%) posterior meniscal root injuries were identified. The root injuries were more likely to have joint line tenderness on preliminary physical examination compared with nonroot injuries (96.5% vs 58.6%, respectively; P < .001). Root injuries rarely occurred in isolation compared with nonroot meniscal tears (6.9% vs 17.6%; P = .021) and were frequently treated in combination with anterior cruciate ligament (ACL) injuries (86.2%). Lateral root injuries occurred more often in conjunction with ACL injuries compared with medial root injuries (84.8% vs 22.2%; P < .001). On review of preoperative imaging, meniscal extrusion occurred more often in root injuries than in nonroot injuries (32.8% vs 3.5%; P < .0001) and was uncommonly seen in the skeletally immature patient. Extrusion was seen more often in medial than lateral root tears (66.7% vs 21.7%; P = .008). A majority of patients (57/58) underwent transosseous suture repair of the meniscal root. CONCLUSION: When treating a pediatric or adolescent patient for a traumatic meniscal tear, a surgeon may expect to see a posterior meniscal root injury in as many as 1 in 6 patients. When treated for an ACL, contact, or multiligament injury or meniscal extrusion, a pediatric or adolescent patient may demonstrate a meniscal root avulsion or complex meniscal tear. These data provide practitioners with an improved ability to identify and treat meniscal root injuries that otherwise lead to rapid cartilage degeneration.
