What is the common cause of ankle sprains?

There are several ligaments that stabilize the ankle. Ankle sports trauma or frequent ankle sprains may cause tears of anterior talofibular ligament and calcaneofibular ligament.

The ligament injuries are classified in three groups according the  severity: 1 – ligament strain, 2 – partial ligament tear, 3 – complete tear of the ligament.If the third group injuries are not treated properly, may cause recurrent ankle sprains or ankle instability.

Do the ligament tears cause further damage?

Frequent ankle sprains not only cause decrease of functional success during sports activity and performance, also, the ankle can be vulnerable to the further injuries.like  cartilage and bony injuries due to the instability.

What is the treatment of recurrent ankle sprains?

In the treatment of ankle sprains, conservative traetment like physical therapy is first treatment aproach. However, when conservative treatment  fails, surgical treatment may be opted.
