Alliance: disease page
Synonyms: Chondromalacia of patella; softening of articular cartilage of patella
Alt IDs: OMIM:168900, ICD10CM:M22.4, ICD9CM:717.7, MESH:D046789, UMLS_CUI:C0008475
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.
