Background: Treatment options for pediatric and adolescent anterior cruciate ligament (ACL) injuries include early operative, delayed operative, and nonoperative management. Currently, there is a lack of consensus regarding the optimal treatment for these injuries. Purpose/Hypothesis: The purpose was to determine the optimal treatment strategy for ACL injuries in pediatric and adolescent patients. We hypothesized that (1) early ACL reconstruction results in fewer meniscal tears than delayed reconstruction but yields no difference in knee stability and (2) when compared with nonoperative management, any operative management results in fewer meniscal tears and cartilage injuries, greater knee stability, and higher return-to-sport rates. Study Design: Systematic review and meta-analysis; Level of evidence, 4. Methods: A systematic search of databases was performed including PubMed, Embase, and Cochrane Library using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Inclusion criteria were a pediatric and adolescent patient population (≤19 years old at surgery), the reporting of clinical outcomes after treatment of primary ACL injury, and original scientific research article. Exclusion criteria were revision ACL reconstruction, tibial spine avulsion fracture, case report or small case series (<5 patients), non–English language manuscripts, multiligamentous injuries, and nonclinical studies. Results: A total of 30 studies containing 50 cohorts and representing 1176 patients met our criteria. With respect to nonoperative treatment, knee instability was observed in 20% to 100%, and return to preinjury level of sports ranged from 6% to 50% at final follow-up. Regarding operative treatment, meta-analysis results favored early ACL reconstruction over delayed reconstruction (>12 weeks) for the presence of any meniscal tear (odds ratio, 0.23; P = .006) and irreparable meniscal tear (odds ratio, 0.31; P = .001). Comparison of any side-to-side differences in KT-1000 arthrometer testing did not favor early or delayed ACL reconstruction in either continuous mean differences ( P = .413) or proportion with difference ≥3 mm ( P = .181). Return to preinjury level of competition rates for early and delayed ACL reconstruction ranged from 57% to 100%. Conclusion: Delaying ACL reconstruction in pediatric or adolescent patients for >12 weeks significantly increased the risk of meniscal injuries and irreparable meniscal tears; however, early and delayed operative treatment achieved satisfactory knee stability. Nonoperative management resulted in high rates of residual knee instability, increased risk of meniscal tears, and comparatively low rates of return to sports.

Tibial shaft fractures are common in the pediatric population. » Traditionally, the majority of pediatric tibial fractures have been managed nonoperatively, but surgical rates are increasing. » Management includes closed reduction and casting, flexible nailing, plate osteosynthesis, external fixation, and rigid intramedullary nailing. » Gustilo-Anderson grade-2 and 3 open pediatric tibial shaft fractures have higher complication rates than closed fractures. » The majority of pediatric tibial shaft fractures have excellent outcomes with an expectation for return to full activities.

Purpose of review To describe surgical treatment options for pediatric tibial shaft fractures which are the third most common pediatric long bone fracture. Management of these injuries is dictated by fracture location, fracture pattern, associated injuries, skeletal maturity, and other patient-specific factors. Although most pediatric tibial shaft fractures can be treated nonoperatively, this review provides an update on surgical treatment options when operative intervention is indicated. Recent findings Advances in surgical implants and techniques affords a wide range of options for the surgical treatment of pediatric tibial shaft fractures. Flexible intramedullary nailing is gaining wide adoption for acute surgical treatment. Recent studies support cross-sectional imaging for further evaluation and scrutiny of fracture patterns suspicious for intraphyseal or intra-articular extension. Grade I open tibial shaft fractures may be safely treated with irrigation and debridement in the emergency department; however, no high-level comparative studies have been performed to make any definitive conclusions regarding the effectiveness of this treatment strategy. Summary Tibial shaft fractures are common injuries in pediatric patients. Management is dictated by fracture location, fracture pattern, associated injuries, patient age, and other patient-specific factors. Surgical intervention is indicated for fractures that are open, irreducible, have failed nonoperative management, are associated with compartment syndrome, or in the multiply injured patient. Surgical treatment options include flexible intramedullary nailing, plate osteosynthesis, external fixation, and rigid intramedullary nailing. Recent literature has shown increased rates of flexible intramedullary nailing. All operative and nonoperative management options can result in complications including compartment syndrome, infection, delayed union, nonunion, malunion, limb length discrepancy, and symptomatic hardware. Most pediatric patients go on to uneventful union with excellent final outcomes and return to full activities.
