Surgery for Chronic Ankle Instability

Ankle instability is a chronic condition which is characterized by a recurrent slipping of the outer or lateral side of the ankle. This is generally noticed during movement of the ankle joint but can also occur during standing as well.

Ankle Instability usually results from repeated ankle sprains. Inadequate healing of a sprained ligament or incomplete rehabilitation of the affected ligament can result in instability. Recurrent injury to the ligaments further weakens them and aggravates the instability which predisposes to the development of additional ankle problems.

Ankle instability surgery is performed to treat an unstable ankle and involves the repair or replacement of a torn or stretched ligament.


There are two types of ankle instability surgery:

  • Anatomic repair: This surgery involves shortening and tightening the stretched ligament; and
  • Non-anatomic repair: This surgery uses a tendon as a graft to replace the damaged ligament.

After an injury or surgery, an exercise conditioning program will help you return to daily activities and enjoy a more active, healthy lifestyle. Following a well-structured conditioning program will also help you return to sports and other recreational activities.

Strengthening the muscles that support your lower leg, foot, and ankle will help keep your ankle joint stable. Keeping these muscles strong can relieve foot and ankle pain and prevent further injury.

Stretching the muscles that you strengthen is important for restoring range of motion and preventing injury. Gently stretching after strengthening exercises can help reduce muscle soreness and keep your muscles long and flexible.
