What are chondromalacia and patellafemoral syndrome?

Knee Pain: Chondromalacia can happen in any joint with articular cartilage. Patellofemoral pain syndrome is chondromalacia of the knee where the patella is maltracking within the groove of the femur (thigh bone). Hope this helps!

Basically the same: Chondromalacia patella (runners knee) is due to overload of the patellofemoral joint (knee cap against the end of the thigh bone). Running caused high forces in this portion of the joint. So does arising from a chair, going up/down stairs. Treatment consists of activity modification, ice, anti-inflammatory meds and therapy aimed at flexibility and strengthening, especially of your core.
