Abstract:
Knee pain is one of the most common issues among young athletes. A medical history and physical examination are required to categorize the pain. Athletic knee injuries can be chronic or acute. Chronic knee pain is commonly secondary to inflammation of the apophysis of the patella or the tibial tuberosity. Repetitive microtrauma of the subchondral bone is another etiology of chronic pediatric knee pain. Acute knee pain typically is associated with a traumatic injury. Patella contact or dislocation can occur because of a noncontact traumatic event.

Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...
