Key findings:
bone bruises of inferomedial patella (blue arrowhead) and the anterolateral femoral condyle (blue arrows)
patellar lateralization (blue double arrow)
medial patellar avulsion fracture with an unstable osteochondral fragment (purple arrow)
medial patellofemoral ligament with a partial tear of the patellar insertion (red arrow) and disruption of the femoral attachment (red arrowheads)
oedema and myotendinous tear of the vastus medialis oblique (VMO) (green arrow)
two chondral fragments (purple arrowheads) between the anterior transverse meniscal ligament and the intercondylar groove
chondral lesion of the antero- and centrolateral femoral condyle (orange arrowheads) with delamination
Assessment for risk factors:
Insall-Salvati index ≈ 1,3 - borderline
decreased trochlear depth (<3mm)
lateral trochlear inclination (LTI) and trochlear facet ratio within normal limits
TT-TG < 15mm
