General Information
Term chondromalacia patellae ID (Ontology) DOID:13357 (Human Disease)
Definition A chondromalacia that is characterized by well-localized pain when the patella is grated against the femoral condyles or when the knee is actively extended with the patella manually displaced distally. This occurs when the posterior articular surface of the patella starts losing its density when in a healthy state and becomes softer with subsequent tearing, fissuring, and erosion of the hyaline cartilage.
Also Known As "Chondromalacia of patella" ; "softening of articular cartilage of patella"
