Left knee pain and swelling, microfracture surgery MENISCI: The medial and lateral menisci are intact.ARTICULAR CARTILAGE AND BONE: There is thickening and increased signal intensity of the articular cartilage of the lateral patellar facet. While this may in part reflect changes of prior microfracture, we suspect that this is primarily degenerative, as there also appears to be delamination of the cartilage and relative thinning of the articular cartilage along the facet inferiorly with additional fissuring. There is also a full-thickness defect along the medial facet of the patella inferiorly. Subjectively, femoral trochlea appears shallow suggesting some dysplasia. The articular cartilage of the lateral and medial compartments is preserved.LIGAMENTS: No significant abnormality noted. EXTENSOR MECHANISM: The patella and quadriceps tendons are intact. There is thickening of the lateral retinaculum at its attachment upon the patella which appears similar to the contralateral side. ADDITIONAL
Articular cartilage degeneration of the patella as described above.
