Abstract
Sinding-Larsen-Johansson syndrome (SLJS) is a rare cause of anterior knee pain in young athletes and is often underdiagnosed due to low clinical suspicion and poorly recognized features. A 9-year-old female tennis player presented with anterior knee pain; radiographs showed patellar fragmentation, and MRI confirmed edema at the patellar tendon insertion. Conservative management with rest resulted in the complete resolution of symptoms and return to sport. This case highlights the clinical and radiological features of SLJS in a 9-year-old athlete, emphasizing the importance of MRI in confirming the diagnosis and facilitating timely management.
