Brief summary: Comparing the physical and sonographic findings of dancers with Chondromalacia patella to non-dancers athletes.

Detailed description: A cross sectional study in which comparing of dancers to non-dancers athletes will be carried. Specifically, chondromalacia patella will be studied and compared between dancers with and without knee injuries and non-dancers athletes.

Study will include detailed function and pain questionnaires, physical findings and sonographic study of the knee joint.
