Morel-Lavallée Lesion of the Knee in the Young Athlete: About 2 Cases After Sports Trauma.
Abstract
BACKGROUND\nDifferential diagnosis of soft tissue swelling on exposed body parts in the young athlete is large and mostly includes benign self-limiting conditions, once underlying lesion to the bone, the cartilage, and the ligaments is excluded. Morel-Lavallée lesion represents a rare soft tissue injury requiring prompt intervention to ensure favorable outcome.\n\n\nCASES\nA 10-year-old boy presented with 2-week-old swelling of the medial side of the knee without recent traumatic event. Unawareness of Morel-Lavallée lesion in the differential diagnosis led to delayed diagnosis and treatment. A 16-year-old boy came to our pediatric tertiary care center with a similar presentation and history. Timely intervention allowed for favorable outcome and early return to play.\n\n\nCONCLUSIONS\nMorel-Lavallée lesion is a rare entity in the pediatric population, although underreporting due to unfamiliarity with the diagnosis is highly probable. Raising awareness among professionals in charge of young athletes should allow for better reporting as well as for elaboration of a standardized treatment plan, including rapid intervention and early return to play.
