Lateral Ankle Instability

Tired of your ankle "giving way"? If repeated sprains have left your ankle feeling unstable, we can help restore strength and stability so you can move with confidence.

Understanding Chronic Ankle Instability

Lateral ankle instability, also called chronic ankle instability (CAI), is a condition where the outer (lateral) side of the ankle repeatedly "gives way," especially during walking, sports, or on uneven surfaces. It typically develops after one or more ankle sprains that didn't heal properly.

When ankle ligaments are stretched or torn during a sprain, they need proper rehabilitation to regain their strength and function. Without adequate treatment and rehabilitation, the ligaments may heal in a weakened, stretched state, leaving the ankle prone to giving way and sustaining additional sprains.

Symptoms of Ankle Instability

  • Repeated ankle sprains or "turning" of the ankle
  • A feeling that the ankle is wobbly or unstable
  • The ankle gives way during everyday activities
  • Persistent discomfort or swelling
  • Difficulty walking on uneven surfaces
  • Feeling uncertain or fearful about ankle stability
  • Pain on the outer side of the ankle

Causes and Risk Factors

  • Previous Ankle Sprains: Especially if not fully rehabilitated
  • Multiple Sprains: Each injury can further weaken ligaments
  • Returning to Activity Too Soon: Before full healing occurs
  • Inadequate Rehabilitation: Not completing physical therapy
  • Anatomical Factors: Naturally loose ligaments or joint laxity
  • Muscle Weakness: Weak stabilizing muscles around the ankle

Diagnosis

Dr. Johnson will perform a thorough evaluation including:

  • Detailed history of ankle injuries and symptoms
  • Physical examination testing ankle stability
  • Assessment of strength, range of motion, and proprioception
  • X-rays to rule out fractures or other bone problems
  • MRI if needed to evaluate ligament and tendon damage

Treatment Options

Non-Surgical Treatment

Many cases of ankle instability respond well to conservative care:

  • Physical Therapy: Strengthening exercises, balance training, and proprioception exercises
  • Bracing: Ankle braces or supports to provide stability during activities
  • Taping: Athletic taping techniques for sports participation
  • Activity Modification: Temporarily avoiding high-risk activities
  • Anti-inflammatory Medications: To manage pain and swelling

Surgical Treatment

When conservative treatments don't provide adequate stability, surgery may be recommended. Dr. Johnson is experienced in ankle stabilization procedures including:

  • Brostrom Procedure: Tightening and repairing the stretched ligaments
  • Brostrom-Gould Modification: Enhanced repair using additional tissue reinforcement
  • Ligament Reconstruction: Using a tendon graft to reconstruct severely damaged ligaments
  • Arthroscopic Procedures: Minimally invasive techniques when appropriate

Recovery and Prevention

Whether treated conservatively or surgically, rehabilitation is key to a successful outcome. A comprehensive rehab program includes:

  • Progressive strengthening of ankle stabilizers
  • Balance and proprioception training
  • Gradual return to activities
  • Learning proper techniques to prevent re-injury
  • Ongoing ankle strengthening exercises
  • Using appropriate bracing during high-risk activities
