There is an acute PCL avulsion fracture at the posteromedian articular surface of the upper tibia. The avulsed fracture fragment is displaced superiorly by approximately 2.3 cm and rotated anteriorly. A large trilevel lipohaemarthrosis is present.
There is acute undisplaced fracture passing through the fibular head.
The proximal tibiofibular articulation aligns normally.
No acute patellar or distal femoral fracture is seen.
CONCLUSION: 1. There is an acute PCL avulsion fracture at the posteromedian articular surface of the upper tibia. The avulsed fracture fragment is displaced superiorly by approximately 2.3 cm and rotated anteriorly. A large likely haemarthrosis is present.
2. There is acute undisplaced fracture passing through the fibular head.
