An update on tibial tubercle avulsion fractures: a narrative review.

Adolescent tibial tubercle avulsion fracture (TTAF) is a rare knee injury resulting from the combination of anatomical fragility and mechanical stress. This narrative review provides an updated synthesis of current evidence on the epidemiology, imaging-based classification, management strategies, and outcomes of TTAF. In this update, we highlight the role of advanced imaging modalities, such as computed tomography (CT) and magnetic resonance imaging (MRI), in improving visualization of fracture morphology and associated soft tissue injuries; review emerging evidence supporting early range of motion (ROM) protocols to enhance postoperative recovery; and summarize recent data on compartment syndrome, emphasizing early recognition and prevention. We correlate fracture morphology, imaging characteristics, and fixation strategies with soft tissue involvement to further refine clinical decision-making. Nonoperative management remains appropriate for Ogden type IA fractures, whereas significantly displaced or complex fracture types require individualized surgical planning and careful selection of fixation devices. This review integrates the latest evidence and clinical practice to provide a concise, evidence-based framework for guiding personalized management of adolescent TTAF and improving patient outcomes.
