Instability Of The Affected Area
Strong ligaments hold the bones of your joints in place while the joints are in motion and at rest. Muscles and tendons hold the bones of the joints in place most often when moving. Instability happens when these structures weaken.
Conditions
Ankle Instability
Chronic ankle instability often develops after repeated ankle sprains.
Cavus foot
This is a condition in which the foot has a very high arch.
Peroneal Tendon Injuries
A tendon is a band of tissue that connects a muscle to a bone. The two peroneal tendons in the foot run side by side behind the outer ankle bone.
