Male, 24 years old. Left knee crepitance, suspicion for chondromalacia of patella. Left knee pain with running MENISCI: There is poorly defined globular intermediate signal intensity within the periphery of the medial meniscus at the junction of the body and posterior horn and abutting the tibial articular surface, suspicious for an undersurface fraying/tearing in the red zone. We see no fluid signal intensity within the meniscus, and therefore it is possible that this represents a healed tear. The remainder of the medial meniscus appears normal. The lateral meniscus appears normal.ARTICULAR CARTILAGE AND BONE: Articular cartilage appears normal as does the bone marrow.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1.Intermediate signal intensity within the periphery of the medial meniscus as described above suggesting undersurface fraying/tearing. Please note that this may be chronic and not necessarily of current clinical significance.2.Normal appearing articular cartilage.3.Small Baker's cyst.
