The Most Common Ankle Injuries — And How Physical Therapy Can Help You Recover Stronger

March 17, 2026

Ankles do a lot more work than we give them credit for. Whether you’re running, walking, playing sports, or just stepping off a curb, your ankles absorb impact, stabilize your body, and keep you moving. Because of this constant demand, they’re also one of the most commonly injured joints.

Let’s take a closer look at the most frequent ankle injuries—and how physical therapy plays a key role in recovery, prevention, and long-term strength.

Ankle Sprains

What it is:
An ankle sprain occurs when the ligaments that support the ankle are stretched or torn, often from rolling or twisting the ankle awkwardly.

Common causes:

• Sports involving jumping or quick direction changes

• Uneven surfaces

• Wearing unsupportive footwear

Symptoms:

• Pain and swelling

• Bruising

• Difficulty bearing weight

How physical therapy helps:
Physical therapy focuses on restoring range of motion, reducing swelling, and rebuilding strength. A therapist may guide you through balance exercises, mobility drills, and strengthening routines to prevent future sprains. Rehab is especially important because untreated sprains can lead to chronic instability.

Achilles Tendinitis

What it is:
This condition involves inflammation of the Achilles tendon, which connects your calf muscles to your heel.

Common causes:

• Overuse, especially in runners

• Sudden increase in activity level

• Tight calf muscles

Symptoms:

• Pain along the back of the ankle

• Stiffness, especially in the morning

• Tenderness when moving

How physical therapy helps:
Treatment often includes targeted stretching, strengthening (especially eccentric exercises), and techniques to reduce strain on the tendon. Therapists also correct movement patterns to prevent recurrence.

Ankle Fractures

What it is:
A fracture is a break in one or more bones of the ankle, often caused by trauma such as a fall or accident.

Common causes:

• High-impact injuries

• Sports collisions

• Severe twisting motions

Symptoms:

• Intense pain

• Swelling and bruising

• Inability to walk

How physical therapy helps:
After immobilization or surgery, physical therapy is essential for regaining mobility, strength, and function. Rehab focuses on restoring normal walking patterns, improving joint flexibility, and rebuilding muscle strength safely.

Peroneal Tendon Injuries

What it is:
These injuries affect the tendons along the outer side of the ankle, which help stabilize the foot.

Common causes:

• Repetitive stress

• Ankle instability

• Previous sprains

Symptoms:

• Pain on the outside of the ankle

• Swelling

• Weakness or instability

How physical therapy helps:
Therapy includes strengthening the surrounding muscles, improving ankle stability, and correcting biomechanical issues. Balance training is especially important to prevent reinjury.

Chronic Ankle Instability

What it is:
A condition where the ankle repeatedly gives out, often due to previous untreated or poorly healed sprains.

Common causes:

• Repeated ankle injuries

• Weak stabilizing muscles

• Poor proprioception (body awareness)

Symptoms:

• Frequent rolling of the ankle

• Persistent discomfort

• Feeling of “giving way”

How physical therapy helps:
This is where physical therapy truly shines. Treatment emphasizes neuromuscular training, balance work, and strengthening to retrain the body’s ability to stabilize the joint. Over time, this can significantly reduce the risk of future injuries.

 

Why Physical Therapy Matters

It’s tempting to “walk off” an ankle injury—but skipping proper rehab can lead to long-term issues like weakness, stiffness, and repeated injuries.

Physical therapy doesn’t just help you recover—it helps you come back stronger by:

• Improving mobility and flexibility

• Restoring strength and endurance

• Enhancing balance and coordination

• Preventing future injuries

When Should You See a Physical Therapist?

Consider seeking help if:

• Pain or swelling lasts more than a few days

• You have difficulty walking or bearing weight

• Your ankle feels unstable

• You’ve had repeated ankle injuries

Early intervention can dramatically speed up recovery and reduce complications.

 

 

Ankle injuries are common, but they don’t have to become chronic problems. With the right care and a structured physical therapy program, you can recover fully—and even improve your overall movement and resilience.

Taking your rehab seriously today can save you from bigger issues tomorrow. Your ankles will thank you for it.
