RÉSUMÉ
Knee injuries are prevalent among young athletes, and an accurate diagnosis is essential for effective treatment. Knee pain is a widespread issue among adolescent athletes. About 50% of athletes experience knee pain every year, and an estimated 2.5 million sports-related knee injuries occur annually in young athletes. The study discusses common knee injuries, including fractures, cartilage damage, patellar injuries, and meniscus tears. It highlights the Ottawa knee rules (OKRs) as a valuable clinical decision tool for guiding the necessity of knee X-rays, emphasizing their high sensitivity and potential cost savings. Prevention strategies for youth athletes, such as injury prevention programs and neuromuscular training, are also discussed. Additionally, the review underscores the importance of radiation exposure and patient safety when utilizing diagnostic imaging, emphasizing adherence to radiation safety principles and the ALARA principle. In conclusion, this review emphasizes multifaceted role of X-rays in diagnosing knee injuries and importance of evidence-based decision rules, prevention strategies, and radiation safety in adolescent knee healthcare.
