Ankle Sprains and Instability
Chronic ankle instability is a condition characterized by a recurring “giving way” of the outer (lateral) side of the ankle. This condition often develops after repeated ankle sprains. Usually the “giving way” occurs while walking or doing other activities, but it can also happen when you’re just standing. Many athletes, as well as others, suffer
from chronic ankle instability.
People with chronic ankle instability often complain of:
- A repeated turning of the ankle, especially on uneven surfaces or when participating in sports
- Persistent (chronic) discomfort and swelling
- Pain or tenderness
What Causes It?
Chronic ankle instability usually develops following an ankle sprain that has not
adequately healed or was not rehabilitated completely. When you sprain your ankle, the connective tissues (ligaments) are stretched or torn.
The ability to balance is often affected. Proper rehabilitation is needed to strengthen
the muscles around the
ankle and “retrain” the tissues
within the ankle that affect balance.
Repeated ankle sprains often cause—and perpetuate—chronic ankle instability. Having an ankle that gives
way increases your chances of spraining your ankle repeatedly. Each subsequent sprain leads to further weakening
(or stretching) of the ligaments—resulting in greater instability and the likelihood of developing
additional problems in the ankle.
