Case 293

assigned

Report English

Medial Compartment: Normal bone marrow signal. Consistently delineated superficial cartilage irregularities in the medial femorotibial area. Persistent suspicion of a displaced flap tear of the posterior root of the medial meniscus (Series 4/ Image 24). Intact MCL. Lateral Compartment: Normal bone marrow signal. Consistently delineated focal deep cartilage defect in the dorsal weight-bearing zone of the lateral femoral condyle (Series 5/ Image 24). Consistently delineated substance reduction at the free edge of the lateral meniscus following partial lateral meniscectomy. Intact LCL. Femoropatellar Joint and Trochlea: Normal bone marrow signal. Compared to the previous examination on 19.12.2023, consistently delineated focal deep cartilage damage at the patellar apex (Series 7/ Image 11) and on the medial patellar facet (Series 7/ Image 12). Consistently delineated, partially deep cartilage damage in the trochlea (Series 7/ Image 17). No full-thickness cartilage defect. No subchondral bone edema. Normal depiction of the quadriceps and patellar tendons. Normal depiction of Hoffa's fat pad. Cruciate Ligaments: Status post ACL and PCL reconstruction with moderate adjacent arthrofibrosis and cysts around the femoral drill hole of the ACL reconstruction. Both ACL and PCL reconstructions are intact. Musculature and Other Soft Tissues: No joint effusion. Fabella. Compared to the last examination on 19.12.2023, consistently advanced chondropathy retropatellar, in the trochlea, and on the lateral femoral condyle. No new deep or full-thickness cartilage defect. - Persistent suspicion of a displaced flap tear of the posterior root of the medial meniscus. No new meniscal tear formation. - Following partial lateral meniscectomy, consistently delineated substance reduction at the free edge. - Intact ACL and PCL reconstruction with moderate adjacent arthrofibrosis. - No joint effusion.
