Report English

Medial Compartment: Normal bone marrow signal. Intact cartilage. Mucoid degeneration of the posterior horn of the medial meniscus with an intact meniscus. Intact MCL. Lateral Compartment: Normal bone marrow signal. Intact cartilage. Intact lateral meniscus. Intact LCL. Patellar Tracking: Intact cartilage. Patella: Normal bone marrow signal. Intact cartilage behind the patella. Normal patellar ligament. Cruciate Ligaments: Status post ACL reconstruction. Normal drill hole canal. No evidence of a cyclops lesion. Scar tissue in the posterior part of Hoffa's fat pad (Series 7/Image 18). Intact PCL. Musculature and Soft Tissues: Accentuated joint fluid. Normal ligament reconstruction post ACL surgery without evidence of a cyclops lesion, but with significantly scarred Hoffa's fat pad in the posterior part. Accentuated joint fluid. Otherwise, intact internal knee structures and ligament apparatus.
