Knee instability, pain, and edema. MENISCI: Globular signal is present in the posterior horn of the medial meniscus, likely degenerative, without discrete tear. The lateral meniscus is unremarkable.ARTICULAR CARTILAGE AND BONE: No significant abnormality noted.LIGAMENTS: The cruciate and collateral ligaments are intact.EXTENSOR MECHANISM: There is moderate soft tissue edema at the anterior aspect of the knee along the extensor mechanism. Thickening and increased signal within the anterior fibers of the distal quadriceps tendon likely represents tendinosis or partial tearing, though this extends beyond the field of view of this study. The undersurface fibers are intact. ADDITIONAL
Findings suggestive of tendinosis or partial tearing of the anterior fibers of the distal quadriceps tendon.
