und Reposition - kleine Abscherung aus der medialen Facette. Typische Kontusion auch an der Anschlagstelle am lateralen Femurkondylus.

MRI after

luxation of the patella (axial). There is bone bruise at the medial surface of the patella itself and in the corresponding surface of the lateral condyle of the femur (arrow). The medial retinaculum of the patella is disrupted.

MRI after

luxation of the right patella. There is bone bruise at the medial surface of the patella (axial image) and in the corresponding surface of the lateral condyle of the femur (coronal). The medial retinaculum of the patella is at least partially disrupted.

X-ray and MRI

after luxation of the patella. There is a fragment and bone bruise at the medial surface of the patella and in the corresponding surface of the lateral condyle of the femur. The medial retinaculum of the patella is disrupted.

School ager

with knee pain. AP radiographs of the knees show lateral patellar dislocation bilaterally along with bilateral gracile bones in the femurs, tibiae and fibulae.The diagnosis was Trisomy 18.

Chronische

Patellaluxation bei Tetraspastik seit der Kindheit. Die Patella findet sich lateral des Femurcondylus. Dadurch ist auch die Tibia deutlich pathologisch nach außen rotiert.

Teenager who

fell on their right knee and has pain. AP (above) and Merchant (below left) radiographs of the right knee show lateral displacement of the patella and a small avulsion fragment (sliver sign) medial to the patella. Merchant radiograph of the right knee post reduction (below right) shows appropriate reduction of the patella along with medial soft tissue swelling.The diagnosis was lateral patellar dislocation.
