Ankle Sprains and Ligament Injuries: What You Should Know

Ankle sprains are among the most common injuries we see at Peninsula Orthopedic Associates, whether from an athlete’s quick pivot or an unexpected misstep off a curb. While many people consider ankle sprains minor, untreated ligament injuries can lead to chronic instability and even arthritis. Understanding the anatomy, causes, and treatments for these injuries is crucial to maintaining long-term mobility and strength.

The role of ankle ligaments in stability

Your ankle depends on ligaments — strong, fibrous bands that connect bones — to maintain stability and prevent excessive movement. These ligaments are grouped into three main categories:

Lateral ligaments

These are the most commonly injured ligaments and include the anterior talofibular ligament (ATFL), the calcaneofibular ligament (CFL), and posterior talofibular ligament (PTFL). Lateral ligaments are located on the outside of the ankle and are most vulnerable during inward rolling motions (inversion).

Deltoid ligament

Found on the inside of the ankle, this ligament resists outward rolling (eversion).

Syndesmotic ligaments

These stabilize the bones of the lower leg and are involved in “high ankle sprains.”

When any of these ligaments are overstretched or torn, the stability of the ankle is compromised.

How do ankle ligament injuries happen?

Ankle ligament injuries often occur during:

• A quick twist or roll of the ankle
• Awkward landings from a jump
• Sudden changes in direction during sports

Sprains are classified by severity:

• Grade I: Mild stretching of the ligament
• Grade II: Partial tear of the ligament
• Grade III: Complete rupture of the ligament

These injuries may seem simple, but can lead to long-term issues if not properly treated.

Why MRI matters

While physical exams and X-rays can identify some injuries, MRI imaging provides a more detailed look at the extent of ligament damage. 

At Peninsula Orthopedic Associates, we use in-office MRI to evaluate soft tissue injuries, detect subtle tears, and identify associated issues like bone bruises or cartilage damage. This advanced imaging allows us to confirm diagnoses and create targeted treatment plans.

Treatment options for ankle sprains

The best treatment depends on the severity of the injury:

• Mild to moderate sprains: These are typically treated with RICE (Rest, Ice, Compression, Elevation), temporary bracing, and physical therapy to restore strength and stability.
• Severe or recurrent sprains: Surgery may be necessary to repair completely torn ligaments or address ongoing instability.

Our goal is to help you recover fully and prevent future injuries.

The importance of early treatment

An untreated ankle sprain can lead to chronic instability, reduced mobility, and even arthritis over time. If you’ve experienced multiple sprains or feel like your ankle is unstable, don’t ignore the signs. Early intervention can make all the difference in your recovery and long-term health.
