Whether you need conservative care or advanced ligament reconstruction, every treatment plan is tailored to your condition, lifestyle, and recovery goals.
What Is Lateral Ankle Instability?
Lateral ankle instability is a condition that develops when the ligaments on the outside of the ankle become stretched or torn after repeated ankle sprains. Over time, these ligaments lose their ability to properly stabilize the ankle joint, causing the ankle to repeatedly give way during walking, running, exercise, or everyday activities.
Without proper treatment, chronic ankle instability may lead to additional ligament injuries, cartilage damage, tendon problems, and early ankle arthritis. Early diagnosis allows for more effective treatment and can help prevent long-term complications.
Common Symptoms of Lateral Ankle Instability
Symptoms may include:
- Recurrent ankle sprains.
- Ankle giving out while walking.
- Persistent ankle pain.
- Swelling around the ankle.
- Weakness or instability.

- Reduced balance.

Lateral Ankle Instability Treatment Options
Every lateral ankle instability treatment plan is customized according to the severity of your ligament injury, activity level, and recovery goals.
Conservative treatment may include:
- Activity modification.
- Physical therapy.
- Balance and proprioception training.
- Functional ankle bracing.
- Anti-inflammatory medication.

Many patients recover successfully without surgery. However, when instability persists despite conservative care, surgical treatment may provide the best long-term outcome.

EXCELLENT Based on 102 reviews Posted on Google Wendy Jo CohenTrustindex verifies that the original source of the review is Google. Dr. Perez is a kind and talented doctor. I spent 2 years trying to find someone who could help me with my foot and was given one misdiagnosed after another. Dr Perez found the problem immediately . She got me scheduled for surgery very quickly and now I'm doing PT and am expected to make a complete recovery.Posted on Google MayerlineTrustindex verifies that the original source of the review is Google. I want to give a huge thank you to Dr. Perez for helping to restore the health of my toenails. When I first started treatment, my toenails were all black and I honestly was worried about whether it would ever improve. After 5 treatments (see attached), I noticed a change in the color of my nails, and after 10 treatments, my toenails has gone from black to pink. Images not shown. This process has taught me that healing takes time, patience and consistency. I am so grateful for the care professionalism and treatment plan that I received and after 2 more treatments, I will be moving into maintenance and I cannot be happier with the progress. I cannot wait to wear open toe shoes again without nail polish. 😀 Since my toenails are pink again, the thought of covering them up, may not be an option I will choose.💃Posted on Google Amy XieTrustindex verifies that the original source of the review is Google.

Dr. Perez has a great personality that’s friendly, engaging and thoughtful. She remembers personal details which add to the personal touch that many physicians lack, especially within any specialty. I thought the absolute worse, that I had fungus or that my foot was going to fall off. Turns out it was eczema, but scared me for sure. She brought my mind to ease and actually prescribed the right thing on the first visit. Highly recommend.Posted on Google Eric VillegasTrustindex verifies that the original source of the review is Google. Yesterday was my first visit with Dr. Perez. I was impressed by her practice. Very chic, modern and clean. The technology she uses is above par. I was able to receive some test results immediately. The staff is warm and friendly and definitely conveyed empathy and assurance. This was refreshing. The Doctor took her time with the consultation. She was detailed in her explanation and thorough with her diagnosis and prognosis. She allowed for questions and provided detailed replies and options for treatment. At no time did I feel rushed. The doctor spoke with candor about my circumstances and didn't fill me with any false hope. I appreciated her direct approach on how I got to where I am currently. Even though some of the information shared was difficult to hear, I did leave with an optimistic outlook. I look forward to returning for our follow-up visit and the treatment proposed.

Lateral Ankle Instability Treatment FAQs
Have questions about lateral ankle instability treatment?
Learn more about chronic ankle instability, ligament injuries, treatment options, surgery, recovery, and returning to sports. Here are answers to some of the most common questions our patients ask.
What causes lateral ankle instability?
The most common cause of lateral ankle instability is one or more ankle sprains that did not heal completely. Every sprain can stretch or tear the ligaments responsible for stabilizing the ankle, making future injuries more likely.
Other contributing factors include:
- Previous ligament tears
- Sports injuries
- Running on uneven surfaces
- Poor rehabilitation after an ankle sprain
- High-impact activities
- Generalized ligament laxity
- Foot biomechanics
- Muscle weakness
- Balance deficits
Athletes and active individuals are especially susceptible, particularly those participating in basketball, running, soccer, tennis, and pickleball.
Why does my ankle keep giving out?
A common sign of chronic ankle instability is the feeling that your ankle suddenly “gives out” during walking, exercise, or changing direction. This occurs because damaged ligaments can no longer provide the support needed to keep the ankle stable.
Repeated episodes of instability place additional stress on the cartilage, tendons, and surrounding joints, increasing the risk of long-term damage. If your ankle continues to roll despite completing physical therapy or wearing a brace, a comprehensive evaluation by a foot and ankle specialist is recommended to determine the most appropriate treatment.
How is lateral ankle instability diagnosed?
Diagnosis begins with a detailed medical history and physical examination. Dr. Perez carefully evaluates ligament stability, ankle alignment, walking mechanics, strength, range of motion, and previous injuries.
Depending on your symptoms, diagnostic imaging such as X-rays, MRI, or ultrasound may be recommended to assess ligament damage and identify associated injuries involving cartilage, tendons, or bone.
How long does lateral ankle ligament reconstruction take?
The procedure typically takes about 35 minutes. Most patients can walk immediately in a CAM boot, and physical therapy generally begins around three weeks after surgery.
When can I return to sports after ankle ligament surgery?
Recovery varies depending on your condition and the sport you play. Most patients gradually return to physical activity after completing rehabilitation and regaining strength, balance, and ankle stability.
Can chronic ankle instability heal without surgery?
Many patients improve with physical therapy, balance training, ankle bracing, and activity modification. However, if instability continues despite conservative treatment, ligament reconstruction may be the most effective long-term solution.
