Sudden Onset of Unexplained Leg Pain Following Open Reduction and Internal Fixation of a Displaced Tibial Tuberosity Fracture: A Case Report of Deep Venous Thrombosis in an Adolescent Athlete.

This case report presents a 16-year-old basketball player, who developed deep venous thrombosis (DVT) following surgical intervention for a displaced tibial tuberosity fracture and forearm fractures. Despite few identifiable thrombotic risk factors, the patient's postoperative course was complicated by unexplained leg pain, fever, and ultimately confirmed DVT. Prompt management with therapeutic anticoagulation and multidisciplinary care led to favourable outcomes. High-risk scores and diagnostic challenges underscore the complexity of anticipating a DVT in paediatric orthopaedic patients. This case highlights the importance of clinical vigilance in recognizing and managing DVT in young athletes undergoing orthopaedic surgery. Further research is needed to refine risk stratification and treatment guidelines for paediatric patients to mitigate the potential morbidity of postoperative DVT.
