Instability is the inability of a joint to support weight or maintain balance, a feat which requires coordination between functional ligaments and tendons. Chronic ankle instability often develops after repeated ankle sprains. This condition usually occurs while walking or during other activities, but it can also happen while simply standing. Many athletes suffer from chronic ankle instability.
Chronic ankle instability usually develops following an ankle sprain that has not adequately healed or was not completely rehabilitated. 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 your ankle and retrain your tissues within the ankle that affect balance. Failure to do so may result in repeated ankle sprains. Repeated ankle sprains often cause chronic ankle instability. Each sprain leads to further weakening (or stretching) of your ligaments, resulting in greater instability and the likelihood of developing additional problems in your ankle.
Contact a doctor if you notice:
X-rays or other imaging studies may be helpful in examining your ankle. Based on the evaluation your doctor will determine the best treatment.
In some cases, your doctor may recommend surgery based on the degree of instability or lack of response to nonsurgical approaches. Surgery usually involves repair or reconstruction of the damaged ligament.
Regenerative Medicine Treatments
Regenerative medicine involves the delivery of growth factors to injured joints and tissues to promote the healing process.
