33-year-old female with right patellofemoral syndrome and chondromalacia. Prior arthroscopy with chondroplasty many years prior. MENISCI: The medial and lateral meniscus appear intact.ARTICULAR CARTILAGE AND BONE: There is a partial-thickness articular cartilage fissuring along the medial facet of the patella. There is thinning and irregularity of the articular cartilage along the medial facet of the patella which may represent postsurgical changes versus articular cartilage degeneration or a combination of both. There is subchondral bone marrow signal abnormality within the patella, likely degenerative in etiology. There is relative sparing of the articular cartilage of the medial and lateral compartments.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Partial-thickness articular cartilage fissure along the medial facet of the patella. Thinning and irregularity of the articular cartilage along the medial facet may reflect postsurgical changes versus articular cartilage degeneration as described above.2. Small to moderate size joint effusion. Other findings as described above.
