What are peroneal tendon tears?
A torn peroneal tendon is a kind of injury that causes ankle pain. Tears can either be mild, moderate, or severe.
A mild tear isn’t anything to worry about because it can stabilize the foot and ankle. However, it’s possible for swelling to emerge. It’s not a tear and more of the tendon being overstretched.
A moderate tear is a partial tear of the tendon. There will be swelling, and the ankle and foot will suffer mild or moderate instability.
A severe tear is a complete rupture of the tendon. This will result in excruciating pain, and severe foot and ankle instability.

It can also be caused by chronic ankle and foot overuse, leading to problems like chronic lateral ankle instability.
