Abstract

Introduction: Anterior Cruciate Ligament (ACL) injuries in skeletally immature patients present a multifaceted challenge for orthopedic surgeons, necessitating a nuanced understanding of developmental anatomy, growth physiology, and surgical techniques. Skeletally immature patients, characterized by ongoing skeletal growth with open physes, exhibit distinct biomechanical vulnerabilities predisposing them to ACL injuries. The dynamic interplay between skeletal maturation, neuromuscular coordination, and sports participation underscores the evolving nature of these injuries, demanding tailored management strategies. Clinical Review: Early surgical intervention emerges as a cornerstone in mitigating the sequelae of ACL rupture in skeletally immature patients, with mounting evidence supporting its efficacy in averting concomitant meniscal and chondral pathology. However, the intricate dance between surgical timing, technique selection, and growth plate preservation necessitates meticulous preoperative planning and intraoperative precision. Preoperative assessment entails a comprehensive evaluation of skeletal maturity, incorporating radiographic indices to delineate bone age and growth potential. Orthopedic surgeons navigate a spectrum of ACL reconstruction techniques, balancing the imperative for anatomical fidelity with the imperative to safeguard physeal integrity. Operative options include both the transphyseal technique, involving tunnel placement across the physis, and the physeal sparing technique, which aims to preserve the growth plate while reconstructing the ACL. Furthermore, graft selection is a critical consideration in ACL reconstruction for skeletally immature patients. Options such as patellar tendon, hamstring tendon, and quadriceps tendon grafts offer distinct advantages and disadvantages, requiring careful consideration of patient factors, surgical technique, and postoperative rehabilitation goals. Postoperative rehabilitation assumes paramount importance in fostering optimal functional recovery and mitigating the risk of growth disturbances. Graded rehabilitation protocols, coupled with proprioceptive training, constitute the bedrock of rehabilitation strategies tailored to the unique needs of skeletally immature patients. Clinical Discussion: Longitudinal surveillance emerges as an imperative in the postoperative care continuum, with orthopedic surgeons assuming stewardship in monitoring skeletal maturation and preempting potential growth disturbances. Furthermore, the imperative for ongoing research endeavors underscores the evolving landscape of ACL injury management in this demographic cohort. Conclusion: ACL injuries in skeletally immature patients epitomize a clinical conundrum demanding a synergistic amalgamation of anatomical acumen, surgical finesse, and rehabilitative prowess. Orthopedic surgeons assume a pivotal role in navigating this complex terrain, poised at the forefront of optimizing outcomes and fostering resilience in this vulnerable patient population.
