[An adolescent with knee pain].

Area of Science:

• Orthopedics
• Pediatric Radiology
• Skeletal Physiology

Background:

• Adolescent knee pain is a common clinical presentation.
• Understanding the underlying causes is crucial for appropriate diagnosis and management.
• Skeletal maturation involves dynamic physiological changes in bone and cartilage.

Observation:

• A 16-year-old male experienced sudden onset of knee pain.
• Imaging revealed focal periphyseal edema of the distal femur.

Findings:

• The observed periphyseal edema is a physiological reaction.
• This reaction is specifically associated with the period of skeletal maturation.
• The distal femur is a common site for such changes.

Implications:

• This condition represents a normal physiological response, not necessarily a pathology.
• It aids in differentiating benign causes of knee pain from more serious conditions.
• Awareness of this phenomenon can prevent misdiagnosis and unnecessary interventions in adolescents.
