This diagnosis has come to be defined as any condition which creates a painful kneecap. In actuality, it is a diagnosis which can only be made when obvious articular cartilage changes are seen on MRI (magnetic resonance imaging) or through an arthroscope.
Chondromalacia patella is a painful outcome of some abnormal mechanical problem with patella (kneecap) tracking.

Treatment can include icing, bracing, anti-inflammatories and a rehabilitative exercise program which may include patellar taping for sports participation. Specific rehabilitative exercises to teach proper tracking of the patella are usually extremely helpful. These exercises will include straight leg raises which will strengthen the group of muscles known as the "quadriceps."
