Abstract:
We present the case of a 28-year-old competitive runner with iliotibial band (ITB) friction syndrome associated with a synovial cyst. Magnetic resonance imaging (MRI) did not demonstrate a fluid collection. However, open exploration revealed a large cyst beneath the ITB arising from the capsule of the knee proximal to the lateral meniscus. The cyst disappeared on extension. The pre-operative MRI scan may have revealed the cyst, if it had been taken with the knee flexed.

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 to...
