 After discussing about the anatomy of the pustulatal corner, now I am going to discuss about the injuries of the pustulatal corner. The most common pattern of injury is due to direct blow to the intramedial tibia in the extended position of the knee that creates a lateral force and that will gap open the lateral side of the knee resulting in injury of the pustulatal corner structures. Other mechanisms may be due to rotatory subluxation or hyperextension. A laterally directed force will lead to impaction injuries between the medial femoral and the tibial condyles. So, it will result in a kissing contusion of the structures and this can be a hint to the presence of pustulatal corner injury. Again, you have to look at the three major structures namely the lateral-colatel ligament, the perplitius myotendinus unit and the perplitifibular ligament. Now, it is time to see some cases. First we will review a sagittal fat set PD image of the knee. From the extreme lateral aspect, first you get to see the partiality of the lateral-colatel ligament. Then, you can appreciate the avulsion of the fibular head. This is due to the avulsion of the bicep femoris tendon. Subsequent to this, you can see the avulsion of the perplitifibular ligament, then the arqueate ligament and pustular capsule injury, then the perplitius myotendinus junction injury and do not miss the p-shell avulsion. Now, we will see the coronal images from the anterior to posterior. There is a big chunk of bone from the antrolateral tibia. This is attached to the iliotubal band, so this is due to the avulsion of the iliotubal band. Behind this, there is lateral-colatel ligament which is wavy and there is tear from the femoral attachment. You can appreciate the increased signal in the attachment of the perplitifibular tendon but tendon is not torn. The perplitifibular ligament is partially torn with increased signal and there is complete avulsion of the bicep femoris tendon from the fibular attachment. The same case, sagittal images showing there is torn lateral-colatel ligament as well as the bicep femoris tendon. There is injury to the grade 1 injury to the perplitifibular ligament and the arqueate ligament pustular capsule injury and there is a sagittal injury of the ACL, complete tear.
