If your ankle keeps giving way during everyday activities — or you’re dealing with repeated sprains that never seem to fully resolve — you may be living with chronic ankle instability. This condition is more than just a recurring nuisance. Left untreated, it can limit your mobility, interfere with work and exercise, and lead to long-term joint damage. At Momentum Foot & Ankle in Boynton Beach, FL, Dr. Christopher Zimmer provides expert, personalized care designed to restore your stability and get you back to the activities you love.
Dr. Christopher Zimmer, DPM, is a board-eligible, fellowship-trained foot and ankle surgeon with advanced training in complex lower extremity conditions, including chronic ankle instability and ligament reconstruction. He completed a dedicated Trauma & Reconstruction Fellowship at Westside Regional Medical Center in Plantation, FL, and his residency at Baylor Scott & White Medical Center — where he gained extensive experience managing hundreds of foot and ankle cases across all severity levels.
At Momentum Foot & Ankle, Dr. Zimmer takes an honest, evidence-based approach to care. He believes surgery should only be recommended when conservative treatment hasn’t provided lasting relief — and he’ll always take the time to explain your diagnosis, your options, and what to expect at every step.
What Is Chronic Ankle Instability?
Chronic ankle instability occurs when the ligaments supporting the outer ankle are stretched or torn — most commonly after an ankle sprain that wasn’t given adequate time to heal. When ligaments heal in a weakened or elongated state, the ankle loses its structural support, making it prone to repeated injury.
This condition can affect anyone, from athletes and active professionals to individuals who simply stepped off a curb the wrong way. Without proper treatment, the instability tends to worsen over time.
Common Symptoms
Chronic ankle instability doesn’t always present the same way in every patient. Common signs include:
- Recurring ankle sprains or a feeling that the ankle “gives way”
- Persistent pain or tenderness along the outer ankle
- Swelling that comes and goes
- A sense of weakness or looseness in the ankle joint
- Difficulty walking on uneven surfaces or during athletic activity
What Causes Chronic Ankle Instability?
The most common cause is an incompletely healed ankle sprain — particularly when a patient returns to activity too soon. Other contributing factors include:
- A history of multiple ankle sprains
- Poor balance, coordination, or muscle weakness
- High-impact sports or repetitive physical activity
- Structural foot issues, such as high arches
Diagnosing Chronic Ankle Instability
Diagnosis begins with a thorough physical examination. Dr. Zimmer will assess your ankle’s range of motion, strength, and stability. Depending on your presentation, imaging studies — including X-rays or MRI — may be ordered to evaluate ligament integrity, rule out fractures, and identify any underlying structural concerns. An accurate diagnosis is the foundation for an effective, individualized treatment plan.
Treatment Options
Treatment is tailored to the severity of your instability and your personal goals. Many patients find lasting relief through conservative care, including:
- Physical therapy focused on strength and balance training
- Ankle bracing or supportive footwear
- Anti-inflammatory medications to manage pain and swelling
- Activity modification during recovery
When conservative measures don’t provide sufficient improvement, surgical intervention may be appropriate. Dr. Zimmer is experienced in lateral ankle ligament reconstruction — including the Broström procedure — which repairs and tightens the damaged ligaments to restore long-term stability and function.
