Left knee pain MENISCI: There is intrasubstance degeneration of the posterior horn of the medial meniscus. Some signal abnormality extends to the tibial articular surface indicating superficial fraying. No fluid-filled tear is evident. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is full-thickness articular cartilage degeneration along the median eminence of the patella. There is a linear focus of low signal intensity within the articular cartilage of the femoral trochlea, centrally, likely representing a partial-thickness articular cartilage cleft. There is relatively 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. There is increased signal abnormality within the mid substance fibers of the patellar tendon which may reflect mild tendinosis. No fluid-filled tear is evident.ADDITIONAL
Large loculated fluid collection within the subcutaneous tissue along the anterior aspect of the patellar tendon which appears most consistent with a hemorrhagic subcutaneous infrapatellar bursitis, although the inferior extent of this collection is not included in its entirety on this examination. Other findings as described above.
