Fig. 1: MR T2 Axial. Lost articular cartilage, the lateral aspect of the patela.

Fig. 2: Axial STIR MRI. Area hiperintensa in apex of the patela, which corresponds to osteocondral injury.
Findings:
Perdida del cartílago articular, en el aspecto lateral de la patela, por condromalacia. Se encuentra zona hiperintensa en el vértice de la patela, que corresponde a lesión osteocondral.

Lost articular cartilage, the lateral aspect of the patela, for chondromalacia. Hiperintensa area is located at the apex of the patela, which corresponds to osteocondral injury.
Diagnosis:

CHONDROMALACIA PATELLAE GRADE IV
Discussion:
Las lesiones del cartílago patelar, se clasifican en:
Grado 1: Cartilago blando, al comprimirlo durante artroscopia.
Grado 2: Lesion que compromete menos del 50% del espesor de la patela.
Grado 3: Lesion que compromete mas del 50% del espesor de la patela.
Grado 4: Lesión del cartílago, con lesión ostocondral asociada.

The patellar cartilage lesions were classified as:
Grade 1: soft cartilage, to compress during arthroscopy.
Grade 2: Lesión which compromises less than 50% of the thickness of the patela.
Grade 3: Lesión which commits more than 50% of the thickness of the patela.
Grade 4: cartilage damage, injury ostocondral partner.
