Summary
Sinding-Larsen-Johansson syndrome, a knee condition in young athletes, is caused by excessive patellar tendon force. Ultrasonography is key for diagnosis and monitoring recovery, which was complete in a 13-year-old football player after rest.
Area of Science:
- Pediatric Orthopedics
- Sports Medicine
- Radiology
Background:
- Sinding-Larsen-Johansson syndrome shares pathogenesis with Osgood-Schlatter disorder.
- It results from excessive patellar tendon force on the inferior patellar pole.
- Clinical signs include pain during flexion, swelling, and functional limitation.
Purpose of the Study:
- To present a case of Sinding-Larsen-Johansson syndrome in a young athlete.
- To highlight the diagnostic utility of ultrasonography (US).
- To emphasize the effectiveness of conservative management.
Main Methods:
- Case presentation of a 13-year-old competitive football player.
- Clinical examination revealing anterior knee pain and swelling.
- Ultrasonography confirmation of lesions consistent with Sinding-Larsen-Johansson syndrome.
Main Results:
- The patient experienced spontaneous anterior knee pain and inferior patellar swelling.
- Ultrasonography confirmed the diagnosis.
- Complete recovery was achieved after five months of conservative management (rest from sports).
Conclusions:
- Sinding-Larsen-Johansson syndrome requires prompt diagnosis and management.
- Ultrasonography plays a crucial role in evaluating this condition.
- Conservative treatment, including rest, leads to full recovery in affected young athletes.

Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.
