Differences in Short-Term Sport-Specific Functional Recovery After Primary ACL Reconstruction in the Adolescent Athlete.

BACKGROUND: Although anterior cruciate ligament (ACL) injury rates have been studied extensively, it is unclear whether levels of functional and psychological readiness for return-to-sport after primary ACL reconstruction (ACLR) differ based on an athlete's primary sport. HYPOTHESIS: Youth athletes in different primary sports will demonstrate differences in short-term functional recovery, as well as patient-reported psychological and functional recovery after primary ACLR. STUDY DESIGN: Retrospective cohort study of consecutive patients treated for ACL injury in pediatric sports medicine clinics. LEVEL OF EVIDENCE: Level 3. METHODS: Patients included underwent primary ACLR between December 1, 2015 and December 31, 2019 and reported sports participation at the time of injury. Demographic data, sports participation, surgical data, functional testing scores (Y-Balance Test [YBT]), functional and psychological patient-reported outcome measures (PROMs), and timing of return-to-play clearance were reviewed. YBT scores were the primary metric for clearance. Four groups were studied: soccer, football, basketball, and other. RESULTS: A total of 220 male and 223 female athletes were included; 65.28% of soccer players were female and 100% of football players were male (P < 0.01). At initial postoperative YBT testing (6-9 months), soccer players had higher operative (P < 0.01) and nonoperative (P < 0.01) leg composite scores when compared with basketball players. No significant differences were found between sports in functional or psychological PROMs at presurgical baseline or 6 months postoperatively. When compared with football, soccer players completed functional clearance in a shorter time from surgery (P = 0.02). Multivariate analysis showed level of competition as a significant independent variable for clearance in female athletes. CONCLUSION: After primary ACLR, athletes, especially female athletes, demonstrated short-term sport-specific differences in YBT scores. Soccer players attained clearance sooner than football players. Level of competition influenced YBT composite scores in all athletes and time to clearance in female athletes. CLINICAL RELEVANCE: Sport-specific differences in reinjury should be investigated to determine whether changes in return-to-play evaluation should be implemented.

Soft Tissue Cam Impingement in Adolescents: MRI Reveals Impingement Lesions Underappreciated on Radiographs.

BACKGROUND: Femoroacetabular impingement (FAI) has been described as repetitive and abnormal contact between a structurally abnormal proximal femur (cam) and/or acetabulum (pincer), occurring during the terminal range of motion of the hip. While cam and pincer lesions have traditionally been defined as osseous abnormalities, there may be a subset of adolescent patients whose impingement is primarily soft tissue (nonosseous). The existence of a nonosseous cam lesion in adolescents with FAI has not been well described. PURPOSE: To identify and characterize a series of adolescent patients with nonosseous (soft cam) FAI identified on magnetic resonance imaging (MRI) and compare these patients' clinical presentation and outcome with those of a cohort with primary osseous cam FAI in the same age group. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A prospective institutional registry of patients with symptomatic FAI was reviewed. Patients were included if they had an MRI scan and a lateral radiograph of the hip (45° Dunn or frog) at a baseline visit. On MRI, the anterolateral femoral head was evaluated using radial, coronal, sagittal, or axial oblique sequences. A soft cam lesion was identified by the presence of soft tissue thickening of ≥2 mm at the anterolateral femoral head-neck junction. An alpha angle was measured on MRI scans and radiographs when a lesion was identified. The cohort with soft cam lesions was reviewed and findings and outcomes were compared with those of a cohort with osseous cam lesions. Continuous variables were first examined for normality, and then nonparametric tests-such as the Kruskal-Wallis test-were considered. The change between pre- and postoperative patient-reported outcomes (PROs) was described by mean and standard deviation and evaluated with an independent-samples t test. RESULTS: A total of 31 (9.3%) of 332 hips (mean age, 16.4 years [range 13.1-19.6 years]; women, 83.9%) were identified with a soft tissue impingment lesion on MRI at the femoral head-neck junction between the 12 and 3 o'clock positions. These lesions demonstrated a thickened perichondral ring (71%), periosteal thickening (26%), or a cartilaginous epiphyseal extension (3%). The mean alpha angle on MRI was greater than on radiographs (63.5°± 7.9° vs 51.3°± 7.9°; P < .0001). A total of 22 patients (71%) with soft impingement underwent hip preservation surgery. When compared with patients in the osseous cohort who also underwent surgical management, both groups showed similar significant improvements from pre- to postoperatively (soft: modified Harris Hip Score [mHHS], 26.9 ± 18.2; Hip disability and Osteoarthritis Outcome Score [HOOS], 31.4 ± 22.9; osseous: mHHS, 22.8 ± 20.8; HOOS, 27.4 ± 20.1; P < .0001), with a mean follow-up of 3.4 years (range, 1-7 years) in the soft cam cohort and 3 years (1-10.1 years) in the osseous cam cohort. CONCLUSION: Clinicians should be aware of nonosseous or soft cam lesions that cause impingement in adolescent patients without an obvious osseous cam on radiographs. MRI is required to detect these soft cam lesions. When nonoperative treatment fails, the PROs in these patients after operative management are comparable with those in patients with osseous cam lesions. Further research is needed to determine whether the soft cam precedes an osseous cam or whether it is a separate entity.

Variability in Pain Management Practices for Pediatric Anterior Cruciate Ligament Reconstruction.

BACKGROUND: The opioid epidemic in the United States is a public health crisis. Pediatric orthopaedic surgeons must balance adequate pain management with minimizing the risk of opioid misuse or dependence. There is limited data available to guide pain management for anterior cruciate ligament reconstruction (ACLR) in the pediatric population. The purpose of this study was to survey current pain management practices for ACLR among pediatric orthopaedic surgeons. METHODS: A cross-sectional survey study was conducted, in which orthopaedic surgeons were asked about their pain management practices for pediatric ACLR. The voluntary survey was sent to members of the Pediatric Orthopaedic Society of North America. Inclusion criteria required that the surgeon perform anterior cruciate ligament repair or reconstruction on patients under age 18. Responses were anonymous and consisted of surgeon demographics, training, practice, and pain management strategies. Survey data were assessed using descriptive statistics. RESULTS: Of 64 included responses, the average age of the survey respondent was 48.9 years, 84.4% were males, and 31.3% practiced in the southern region of the United States. Preoperative analgesia was utilized by 39.1%, 90.6% utilized perioperative blocks, and 89.1% prescribed opioid medication postoperatively. For scheduled non-narcotic medications postoperatively 82.8% routinely advocated and 93.8% recommended cryotherapy postoperatively.Acetaminophen was the most used preoperative medication (31.3%), the most common perioperative block was an adductor canal block (81.0%), and the most common postoperative analgesic medication was ibuprofen (60.9%). Prior training or experience was more frequently reported than published research as a primary factor influencing pain management protocols. CONCLUSIONS: Substantial variability exists in pain management practices in pediatric ACLR. There is a need for more evidence-based practice guidelines regarding pain management. LEVEL OF EVIDENCE: Level V.

Association of Unmet Social Needs With Level of Capability in People With Persistent Knee Pain.

BACKGROUND: Musculoskeletal providers are increasingly recognizing the importance of social factors and their association with health outcomes as they aim to develop more comprehensive models of care delivery. Such factors may account for some of the unexplained variation between pathophysiology and level of pain intensity and incapability experienced by people with common conditions, such as persistent nontraumatic knee pain secondary to osteoarthritis (OA). Although the association of one's social position (for example, income, employment, or education) with levels of pain and capability are often assessed in OA research, the relationship between aspects of social context (or unmet social needs) and such symptomatic and functional outcomes in persistent knee pain are less clear. QUESTIONS/PURPOSES: (1) Are unmet social needs associated with the level of capability in patients experiencing persistently painful nontraumatic knee conditions, accounting for sociodemographic factors? (2) Do unmet health-related social needs correlate with self-reported quality of life? METHODS: We performed a prospective, cross-sectional study between January 2021 and August 2021 at a university academic medical center providing comprehensive care for patients with persistent lower extremity joint pain secondary to nontraumatic conditions such as age-related knee OA. A final 125 patients were included (mean age 62 ± 10 years, 65% [81 of 125] women, 47% [59 of 125] identifying as White race, 36% [45 of 125] as Hispanic or Latino, and 48% [60 of 125] with safety-net insurance or Medicaid). We measured patient-reported outcomes of knee capability (Knee injury and Osteoarthritis Outcome Score for Joint Replacement), quality of life (Patient-Reported Outcome Measure Information System [PROMIS] Global Physical Health and PROMIS Global Mental Health), and unmet social needs (Accountable Health Communities Health-Related Social Needs Survey, accounting for insufficiencies related to housing, food, transportation, utilities, and interpersonal violence), as well as demographic factors. RESULTS: After controlling for demographic factors such as insurance status, education attained, and household income, we found that reduced knee-specific capability was moderately associated with experiencing unmet social needs (including food insecurity, housing instability, transportation needs, utility needs, or interpersonal safety) (standardized beta regression coefficient [ß] = -4.8 [95% confidence interval -7.9 to -1.7]; p = 0.002 and substantially associated with unemployment (ß = -13 [95% CI -23 to -3.8]; p = 0.006); better knee-specific capability was substantially associated with having Medicare insurance (ß = 12 [95% CI 0.78 to 23]; p = 0.04). After accounting for factors such as insurance status, education attained, and household income, we found that older age was associated with better general mental health (ß = 0.20 [95% CI 0.0031 to 0.39]; p = 0.047) and with better physical health (ß = 0.004 [95% CI 0.0001 to 0.008]; p = 0.04), but effect sizes were small to negligible, respectively. CONCLUSION: There is an association of unmet social needs with level of capability and unemployment in patients with persistent nontraumatic knee pain. This finding signals a need for comprehensive care delivery for patients with persistent knee pain that screens for and responds to potentially modifiable social risk factors, including those based on one's social circumstances and context, to achieve better outcomes. LEVEL OF EVIDENCE: Level II, prognostic study.

The Interobserver Reliability of Grading of Distal Radius Volar Plate Prominence.

PURPOSE: The 3-category rating of volar plate prominence in relation to the most volar edge of the distal radius (the watershed line) on lateral radiographs was reliable among a small group of surgeons and associated with the probability of flexor tendon irritation and potential rupture. Classifications are often less reliable when tested among a large group of practicing surgeons in different environments. METHODS: In this survey-based experiment, an international group of 115 fracture and upper extremity surgeons viewed 1 of 4 sets of 24 lateral radiographs (96 unique lateral radiographs) of patients with distal radius fractures who underwent volar plating in the practice of a single surgeon using 2 types of plates. Surgeons were asked to rate the following metrics: (1) the grade of plate prominence according to Soong, (2) whether the plate was more prominent than the watershed line, (3) whether the plate was separate from the bone distally, and (4) whether there is more than 5° of dorsal angulation of the distal radius articular surface. RESULTS: The interobserver agreement of the classification was "fair" (κ = 0.32; 95% confidence interval [CI] = 0.27-0.36), and grading was more reliable among surgeons who do not supervise trainees. Volar prominence was less reliable (κ = 0.034; 95% CI = 0.013-0.055) than plate separation from bone (κ = 0.50; 95% CI = 0.42-0.59) and more than 5° of dorsal angulation (κ = 0.42; 95% CI = 0.35-0.48). CONCLUSIONS: Among a large number of international practicing surgeons, the classification of volar plate prominence in 3 categories was fair. CLINICAL RELEVANCE: The diagnosis of plate prominence might develop toward criteria with moderate reliability, such as separation of the plate from the bone and residual angulation of the distal radius.

Early Sport Specialization and Past Injury in Competitive Youth Rock Climbers.

INTRODUCTION: Sport specialization has been shown to have negative effects on athletes but has not been studied within rock climbing. This study seeks to evaluate the proportion and impact of specialization in pediatric climbers. METHODS: Climbers (ages 8-18 y) were recruited from throughout the United States to complete a 1-time survey regarding climbing experience, training patterns, and injury history. The main outcome of proportion of climbers suffering an injury was assessed within the last 12 mo and within their entire climbing experience (defined as "lifetime" injury). Early specialization was defined as exclusive participation in climbing, with training for >8 mo‧y-1, prior to age 12 y (late specialization if after age 12 y). RESULTS: Participants (n=111, 14±3 y [mean±SD], 69 females) were high-level climbers. Fifty-five percent of participants specialized in climbing, and 69% of those specialized early. Hand and ankle injuries occurred most commonly. Seventy-eight percent of late specialized climbers had a lifetime injury. Late specialized climbers were 1.6 times (95% CI: 1.1-2.3) more likely than early specialized climbers to have had a lifetime injury and 1.8 times (95% CI: 1.1-2.8) more likely to have had an injury in the last 12 mo. No difference in overuse injuries was found between specialization groups. CONCLUSIONS: Early specialization is common among youth climbers but was not associated with an increase in injuries. Late specialization was associated with a higher likelihood of having had a climbing injury in the last 12 mo and during an entire climbing career.

Epidemiology of Pediatric Basketball Injuries Presenting to Emergency Departments: Sex- and Age-Based Patterns.

BACKGROUND: There is limited epidemiologic data on pediatric basketball injuries and the comparison of these injuries before and after adolescence and between male and female athletes. PURPOSE: To assess common sex- and age-based injury patterns in pediatric basketball players. STUDY DESIGN: Descriptive epidemiology study. METHODS: Injury data from the National Electronic Injury Surveillance System (NEISS) and participation data from the National Sporting Goods Association were used to complete this study. Data on pediatric basketball injuries between January 2012 and December 2018 in patients aged 7 to 11 years (childhood) and 12 to 17 years (adolescence) were extracted and used to calculate national injury incidence rates with 95% CIs. Sex and age group patterns were examined utilizing Pearson chi-square tests. Z tests were conducted for the comparison of injury rates between female and male athletes in each age group and overall injury rate across age groups. RESULTS: An average of 9582 basketball injuries were reported annually in the NEISS, which calculated to an annual national estimate of 294,920 injuries. The most common diagnoses were ankle strain/sprain (17.7%), finger strain/sprain/fracture (12.1%), concussion/head injury (9.4%), knee strain/sprain (4.5%), and facial laceration (3.3%). There was a significant increase in injury prevalence in adolescents (12- to 17-year-old category: 238,678 injuries per year) when compared with childhood (7- to 11-year-old category: 56,242 injuries per year) (P < .0001). Concussions/head injuries occurred at a high rate in childhood, second only to finger strain/sprain/fracture, and at a similar rate in females and males (injuries per 100,000 athlete-days: 4.9 [95% CI, 3.1-6.7] vs. 5.9 [4.3-7.5], respectively; P = .41). From childhood to adolescence, injury prevalence increased for all areas and across both sexes, except for female finger strain/sprain/fracture; however, the rate of increase for concussion/head injuries and knee injuries was significantly higher in female compared with male athletes (P < .0001 for both). In adolescents, ankle injuries were the most common injury overall. CONCLUSION: Ankle injuries continue to be the most predominant pediatric basketball injury. However, disproportionate rates of both knee and concussion/head injuries in female athletes during adolescent basketball are of concern and have implications for injury prevention.

Comparison of Weightbearing and Nonweightbearing Juvenile Osteochondritis Dissecans Lesions of the Lateral Femoral Condyle.

BACKGROUND: Repetitive microtrauma may contribute to osteochondritis dissecans (OCD) lesions of the femoral condyle. The effect of differential loading between OCD weightbearing (WB) zones has not been studied. PURPOSE: To determine whether clinical and radiographic variables differ by WB zone in lateral femoral condyle OCD lesions. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: We retrospectively reviewed a consecutive series of patients aged <18 years with lateral femoral condyle OCD lesions presenting at a single institution between 2004 and 2018. Patients with OCD lesions outside of the lateral femoral condyle were excluded. Lesions were localized on radiographs using the Cahill and Berg classification, referencing the Blumensaat line and an extension of the posterior femoral cortex. Progeny bone characteristics evaluated at baseline and 24-month follow-up included ossification, distinct borders from parent bone, and displacement. Baseline lesion dimensions were measured on magnetic resonance imaging (MRI) scans. We evaluated posttreatment pain level, return-to-activity rate, and patient-reported outcome measures (PROMs) including the Pediatric International Knee Documentation Committee score, Knee injury and Osteoarthritis Outcome Score, and Pediatric Functional Activity Brief Scale. RESULTS: A total of 62 lateral femoral condyle OCD lesions (mean follow-up, 24.1 months) presented within the study period: 26 WB lesions and 36 nonweightbearing (NWB) lesions. At presentation, no differences between the lesion types were observed in symptom chronicity or symptomatology. NWB lesions were deeper on MRI scans (sagittal depth, 7.11 vs 5.96 mm; P = .046; coronal depth ratio, 0.05 vs 0.01 mm; P = .003), were more likely to develop progeny bone (69.4% vs 44%; P = .047), and demonstrated higher radiographic healing rates (52.8% vs 24%; P = .025) compared with WB lesions. PROMs at follow-up were available for 25 of 62 patients (40.3%), with no statistically significant differences between cohorts at any time. Return to full activity was observed in 72% of WB and 82.1% of NWB lesions (P = .378). CONCLUSION: Lateral femoral condyle OCD lesions of the knee in WB and NWB zones presented similarly at initial evaluation; however, NWB lesions demonstrated higher rates of progeny bone formation and radiographic healing at mean 2-year follow-up.

The Association of α Angle on Disease Severity in Adolescent Femoroacetabular Impingement.

BACKGROUND: Femoroacetabular Impingement (FAI) is a common cause of hip pain in adolescent patients. Clinical exam and radiographic markers, such as α angle and lateral center edge angle (LCEA), are commonly used to aid in the diagnosis of this condition. The purpose of this study was to correlate preoperative α angle and LCEA with preoperative symptoms, intraoperative findings, and preoperative and postoperative patient reported outcomes (PROs) in the adolescent patient. METHODS: A retrospective analysis of prospectively collected data was conducted for all patients who underwent operative intervention for FAI at an academic institution over an 11-year period. Preoperative imaging was obtained and measured for LCEA and α angle. PROs (modified Harris Hip Score, Hip Disability and Osteoarthritis Outcome Score, and UCLA score) were collected preoperatively, as well as 1, 2, and 5 years postoperatively. Operative intervention was either open surgical hip dislocation or arthroscopic, and intraoperative disease was graded using the Beck Classification system. Patients with minimum 1-year follow-up were included in statistical analysis. RESULTS: There were 86 hips (64 female hips) included with an average age of 16.3 years (range, 10.4 to 20.5 y), with an average of 37 months of follow-up. There was no correlation between severity of preoperative symptoms or difference between pre and postoperative PROs for both α angle and LCEA. Overall, significant improvement was noted in modified Harris Hip Score, Hip Disability and Osteoarthritis Outcome Score, and UCLA Score (P<0.001 for each). Independent of preoperative symptoms, increased α angle correlated with more severe intraoperative labral disease (P<0.001), and longer length of labral tear (Corr 0.295, P<0.01). Femoral head and acetabular articular cartilage damage did not correlate with α angle or LCEA, nor did overall severity of disease. CONCLUSIONS: In adolescent patients with FAI, increased α angle was found to significantly correlate with labral pathology, including increased length of tear and severity of disease, irrespective of preoperative symptoms or postoperative patient reported outcomes. LEVEL OF EVIDENCE: Level III-retrospective.

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.

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.

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.
