Explanation:

Iliotibial band syndrome is characterized by lateral knee pain that worsens with activities like running and descending stairs. The positive Ober's test (indicating tightness of the iliotibial band) and tenderness over the lateral femoral condyle and lateral knee joint are key findings. Patellofemoral pain syndrome typically presents with anterior knee pain. A meniscal tear often has symptoms like locking or catching of the knee. A lateral collateral ligament sprain would have more specific trauma - related onset and different physical examination findings related to ligamentous instability.

Answer:

A. Iliotibial band syndrome
