The diagnosis was that the extreme eversion and plantar flexion that occurred during the fall resulted in a severe dislocation of the ankle joint proper (talocrural joint) and spraining of the ankle at the calcaneofibular ligament. The surgeon stated that she would perform a reduction of the dislocation and then attempt to repair the injured ligament using arthroscopy. Which bones would have been dislocated?

A form of surgery, which is used for treating the damaged ligaments is known as arthroscopic surgery. In this, a surgical instrument is inserted into the joint by doing a slight cut. This form of surgery minimizes the time of healing as it prevents more destruction of the tissues that surround the site of injury.  

Dislocation refers to a situation in which the bones that form any kind of joint get dislocated from their native location. This eventually results in pain and lesser movement. In the given case, dislocation of the ankle joint has taken place, thus, the bones that would have got dislocated from its position would have been either fibula, tibia, or talus. The movements that generally takes place at the ankle joint are dorsiflexion and plantar flexion.
