Report summary

MRI of the knee shows significant cartilage damage and bone marrow swelling in the outer part of the knee joint (lateral femoral condyle) with an imminent cartilage flap tear, additional cartilage defects, one or two loose bodies, cartilage fissuring at the medial trochlea, and a large joint effusion.

Findings

  • Lateral femoral condyle (mid weight-bearing portion)

    high confidence · not localized
    Significant

    Prominent subcortical marrow oedema with overlying high-grade chondral delamination extending to the subchondral bone plate; oedema extends over 20 mm AP and up to 13 mm transversely

    In plain words: The cartilage covering the outer part of the thigh bone at the knee is peeling away down to the underlying bone, and the bone beneath shows swelling (marrow oedema). 'High-grade' means the cartilage damage is advanced.

  • Medial trochlea

    high confidence · not localized
    Significant

    Prominent subcortical oedema with overlying high-grade chondral fissure extending close to the trochlear groove

    In plain words: The cartilage in the groove where the kneecap slides has a deep crack, with swelling in the bone beneath. 'High-grade' indicates advanced cartilage damage.

  • Knee joint

    high confidence · not localized
    Significant

    Large knee joint effusion

    In plain words: There is a large amount of excess fluid within the knee joint, which often accompanies irritation or injury inside the joint.

  • Posterior non-weightbearing surface of lateral femoral condyle

    high confidence · not localized
    Needs attention

    Full-thickness chondral defect measuring 3 x 9 mm, not associated with subchondral signal abnormality

    In plain words: A small area where the cartilage is worn all the way through, but the bone underneath appears unaffected.

  • Anterior to distal ACL

    high confidence · not localized
    Needs attention

    5 mm loose body anterior to the distal ACL measuring 5 mm

    In plain words: A small free-floating fragment within the joint, located in front of the anterior cruciate ligament.

  • Patella

    high confidence · not localized
    Needs attention

    Minor fissuring affects the patella

    In plain words: There are small surface cracks in the cartilage of the kneecap.

  • Anterior root complex of lateral meniscus

    moderate confidence · not localized
    Needs attention

    Suspected further well-defined loose body closely related to the anterior root complex, measuring up to 6 mm

    In plain words: A possible second free-floating fragment within the joint, near where the outer meniscus attaches.

  • Lateral meniscus

    high confidence · not localized
    Normal

    The lateral meniscus is intact

    In plain words: The meniscus is the C-shaped cushion in the knee; here it is undamaged on this outer side.

  • Lateral tibial plateau

    high confidence · not localized
    Normal

    Chondral surfaces are reasonably well-preserved

    In plain words: The cartilage on the top of the shin bone (tibia) on the outer side is in fairly good condition.

  • Proximal tibiofibular joint

    high confidence · not localized
    Normal

    Normal

    In plain words: The joint between the two lower leg bones near the knee appears normal.

  • Medial femorotibial compartment - meniscus

    high confidence · not localized
    Normal

    No meniscal tear

    In plain words: The meniscus cushion on the inner side of the knee is not torn.

  • Medial femorotibial compartment - cartilage

    high confidence · not localized
    Normal

    Chondral surfaces preserved with no subchondral signal abnormalities

    In plain words: The cartilage and underlying bone on the inner side of the knee joint are healthy.

  • Anterior root complex of lateral meniscus / distal ACL

    moderate confidence · not localized

    Soft tissue signal intensity synovium adjacent to the anterior root complex, extending posterior to the distal ACL

    In plain words: There is some thickened joint-lining tissue (synovium) near where the meniscus attaches, extending toward the anterior cruciate ligament.
