MRI OF THE RIGHT KNEE
HISTORY: Fall 2/2014, medial meniscal tear, bilateral pain.
TECHNIQUE: Multiplanar multisequential MR images were obtained.
COMPARISON: There are no prior studies for comparison.
FINDINGS: There is extensive tearing and maceration of the posterior horn and
body of the medial meniscus including complete radial transection of the
posterior aspect of the body. The anterior horn is intact. There is horizontal
cleavage of the body of the lateral meniscus predominantly filled with granulation
tissue. The anterior and posterior horns are intact.
The anterior cruciate ligament and posterior cruciate ligament are intact. The
lateral collateral ligament complex is intact. The medial collateral ligament is
intact. The quadriceps extensor mechanism as well as the popliteus tendon are
intact. The patella is well located. There is a very small knee joint effusion. There
is no Baker's cyst. The biceps femoris and semimembranosus insertions are
normal. Pes anserinus tendons course normally to their insertions without bursal
distension.
There is moderate medial compartment chondrosis. The lateral compartment
cartilage is preserved. There is moderate to marked patellofemoral chondrosis,
especially affecting the medial patellar facet. There is no fracture or
osteonecrosis.
