Case Discussion
The case shows two avulsion fractures of the knee. One is medial collateral ligament avulsion which is known as Steida fracture. The other avulsion fracture is from the lateral aspect of the tibial plateau which is known as Segond fracture.
MRI was done later which revealed anterior cruciate ligament tear, Steida fracture, and Segond fracture.
