Knee pain and swelling, prior chondroplasty and microfracture of the patella MENISCI: The lateral and medial menisci are intact.ARTICULAR CARTILAGE AND BONE: There is focal increased signal intensity extending through the articular cartilage of the lateral patellar facet that appears slightly less prominent on the current exam when compared to the prior. This may reflect further maturation of cartilage following chondroplasty/microfracture. The articular cartilage along the inferior portion of the medial facet and medial eminence appears thinned with surface irregularity representing degeneration. There is a small focus of signal abnormality within the underlying subchondral bone. Subjectively, the femoral trochlea appears shallow suggesting dysplasia. The articular cartilage of the medial and lateral compartments is preserved. LIGAMENTS: No significant abnormality noted. EXTENSOR MECHANISM: The quadriceps and patellar tendons are normal. There is thickening of the lateral retinaculum at its patellar attachment that appears similar to prior exams. ADDITIONAL
Signal abnormality of the lateral patellar facet appears less prominent than the prior examination suggesting some maturation of cartilage. There is thinning and surface irregularity of the medial patellar facet and patellar eminence suggesting some degeneration.
