Anterior cruciate ligament (ACL) injuries and surgical intervention in the pediatric population have increased in the recent years. Although surgical techniques have advanced, evidence-based rehabilitation guidelines that consider all aspects of the youth athlete are currently lacking. The purpose of this commentary is to review the current evidence on unique considerations for the pediatric and adolescent population during rehabilitation and return to sport after ACL reconstruction (ACLR), with a focus on children under 18 years of age. This review revealed that returning a youth athlete to sport after ACLR requires knowledge and appreciation of various aspects of the growing athlete different from adults. In addition to postoperative precautions that contribute to a slow rehabilitation process, young athletes need additional time for strength gains. Address risk of reinjury and for contralateral injury by using neuromuscular training and rigorous return-to-sport training programs. Consider return to sport after 9 months because the reinjury rate is high in this population. A combination of time and objective measures, both quantitative and qualitative criteria, and psychological readiness should be used to assess readiness to return to sport and decrease risk of future injury. Healthcare providers should be aware of the psychosocial impact of injury on the youth athletes and refer to sport psychology when necessary. Level of Evidence: Level V.O ver the last 2 decades, anterior cruciate ligament (ACL) injuries and surgical intervention in children and adolescents have been increasing. [1][2][3][4][5][6][7] This increase is often attributed to increased participation in competitive organized sports, 8 early sports specialization, 9 and year-round training and competition. 10 Furthermore, advancements in surgical techniques allow for early reconstruction of the ACL in the

Purpose of reviewThe purpose of this review is to outline the most recent understanding of torticollis in the pediatric population.Recent findingsIt is important to diagnose the underlying condition of torticollis early in childhood, as some conditions that cause torticollis may result in major developmental delays in early motor milestones. Recent studies have highlighted that many of the rarer causes of torticollis are often misdiagnosed as congenital muscular torticollis, suggesting that physicians should pay close attention to the results of clinical and radiographic examinations when patients present with torticollis.SummaryCongenital muscular torticollis is the most common cause of torticollis. Other, less common causes of torticollis include vertebral abnormalities, ocular torticollis, gastrointestinal disorders, soft tissue infections of the neck, posterior fossa tumors, and benign paroxysmal torticollis. Although rare, these differential diagnoses should be considered during a clinical work-up for a patient who presents with torticollis.

Purpose of reviewAcute ankle sprains frequently occur in active children and adolescents but may be the initial clinical presentation of other less common disorders affecting the lower extremities. There are many conditions that may cause one or multiple episodes of ankle injury that are misdiagnosed as an acute ankle sprain. This manuscript highlights diagnoses that should be considered when evaluating and managing a child or adolescent who presents initially and/or repeatedly with an acute ankle sprain. Recent findingsIn recent years, various studies have continued to note the prevalence of misdiagnosed ankle sprains, especially amongst the paediatric population. If ankle radiographs demonstrate no abnormalities during an initial clinical examination, often the patient is diagnosed with an acute ankle sprain. However, this can be a misdiagnosis, especially when the patient has had recurrent episodes of ankle injury and ancillary studies are not performed.

Background: To the authors’ knowledge, no previous study has thoroughly described the anteroposterior dimensions of tibial spine fractures (TSFs) on 3-dimensional imaging. The extension of TSFs into weightbearing regions of the tibial plateau, posterior extension within the epiphysis, and potential association between fracture size and patient age may have implications for treatment strategies and clinical outcomes. Hypothesis: TSF fragments would commonly involve weightbearing regions of the tibial plateau, would be larger in younger patients, and would extend more posteriorly than the anatomic footprint of the tibial spine. Study Design: Case series; Level of evidence, 4. Methods: Consecutive magnetic resonance imaging studies obtained between 2012 and 2020 in patients 5 to 18 years of age at the time of imaging for TSFs were included, measured, and classified via the Green and Tuca grading system. Anteroposterior fracture dimensions were measured and normalized to anteroposterior midepiphyseal length, as was fracture height to epiphyseal height. Extension into the weightbearing surface of the tibial plateau was recorded. Intraclass correlation coefficient and kappa values were calculated. Mean fracture bed size was compared using independent-samples t tests between older and younger patients based on median age and sex. Results: Of 54 TSFs, 1 (2%), 28 (52%), and 25 (46%) were grades 1, 2, and 3, respectively. Fracture beds spanned 45% of the anteroposterior midepiphysis, and 54% of the TSF beds extended to the posterior third of the epiphysis. Younger and female patients, on average, had larger anteroposterior dimensions to TSF beds ( P = .018 and .006, respectively). The medial and lateral weightbearing surfaces of the tibial plateau were affected 57% and 25% of the time, respectively. Conclusion: This study demonstrated that TSF beds were larger in younger patients, extended to the posterior third of the epiphysis in 54% of cases, and should be examined carefully for extension into weightbearing regions of the tibial plateau. In pediatric patients, the TSF often involves more of the tibial plateau than the anatomic footprint of the tibial spine, and clinicians should be aware of the potential for extension posteriorly and into the weightbearing surfaces.

Background: The incidence of anterior cruciate ligament (ACL) reconstruction (ACLR) in children and adolescents has increased significantly, and many such patients are at increased risk for ACL retear. Lateral extra-articular tenodesis (LET) may be performed in conjunction with ACLR to reduce the risk of ACL retear. Purpose: To evaluate the 2-year clinical outcomes of ACLR with soft tissue quadriceps tendon (QUAD) autograft performed with a concomitant LET using a modified Lemaire technique in skeletally immature patients. Study Design: Case series; Level of evidence, 4. Methods: A consecutive series of adolescent patients who underwent QUAD autograft ACLR and LET with a minimum of 2 years of follow-up data were analyzed retrospectively. ACLR techniques, including all-epiphyseal and complete transphyseal, were indicated based on skeletal age. Outcome measures included return to sports, concomitant or subsequent surgical procedures, and multiple patient-reported outcome measures, including Single Assessment Numeric Evaluation (SANE), Pediatric International Knee Documentation Committee (Pedi-IKDC), and Hospital for Special Surgery Pediatric Functional Activity Brief Scale (HSS Pedi-FABS) scores. Results: The final cohort included 49 consecutive adolescent patients aged 11 to 16 years (mean, 14.2 ± 1 years) with a minimum follow-up of 2 years. One patient was lost to follow-up. Of the patients included in the study (N = 48; 27 male, 21 female), 98% participated in high-risk competitive sports. Two (4%) patients were undergoing revision ACLR. Thirty-eight (79%) patients underwent complete transphyseal, and 10 (21%) patients underwent all-epiphyseal ACLR. Sixteen (33%) patients had subsequent surgical procedures, including 5 contralateral ACLR, 4 meniscal surgery, 4 QUAD autograft scar revision, 4 irrigation and debridement (2 patients, 2 each), and 3 hardware removal (2 for hemi-epiphysiodesis and 1 tibial socket button removal) procedures. The rate of graft rupture was 0%. At a mean follow-up of 3.4 ± 1.2 years (range, 2-7 range), the mean SANE score was 93, the mean Pedi-IKDC score was 89, and the mean HSS Pedi-FABS score was 23. The return-to-sports rate was 100%. Conclusion: An LET performed concomitantly with an ACLR is safe and should be considered as a concomitant procedure for adolescent patients with nonmodifiable risk factors who are at high risk of retear.
