In reply to ryan_d:
> (In reply to Andy Ayres) Thats completely inaccurate. Patello femoral syndrome is where the illio tibial band is too tight and pulls on the tendons of the knee cap, pulling it slightly out of alignment, usually to the lateral side.
Please explain how I am completely inaccurate?
A tight IT band, as you have descibed will cause abnormal patella traking leading to an increase in pressure between the posterior lateral surface of the patella and the anterior lateral surface of the tochlear goove on the femur. It is the increase in pressure between the patella and the femur that causes pain with in the patellofemoral joint.
Other factors (but not all of them) that can cause patellofemoral pain include patalla alta (high patella in relation to trochlear groove), increased Q-angle, femoral torsion and abnormal foot pronation (though the how and why is poorly understood).
Due to pressure between the 2 bodies being highest when the knee if flexed pain can be increased by going up and down stairs, walking and running and kneeling.
