Ankle sprain and instability

Ankle sprains stretch or tear the ligaments that stabilize the ankle, most often on the outside after an inversion roll. Some people heal cleanly; others are left with recurring give-way.

What it feels like

Acute sprains bring lateral ankle pain, swelling, bruising, and trouble with push-off or uneven ground.

With chronic instability, people describe repeated rolling, hesitation on trails, or a sense the ankle is unreliable.

Lingering stiffness and weakness are common even after the original bruise fades.

What is going on

The anterior talofibular and related lateral ligaments are the usual injured structures in inversion sprains.

Incomplete rehab of proprioception and strength is a major reason sprains become recurrent.

High ankle (syndesmotic) sprains and osteochondral injury are important variants we do not want to miss.

How we evaluate

Mechanism, Ottawa-style fracture screening, ligament tenderness, and stress testing guide acuity.

We assess balance, strength, and mechanical laxity in people with recurrent give-way.

Imaging is used for suspected fracture, high ankle injury, or refractory instability planning.

What we may offer

Protected motion, swelling control, and progressive physical therapy are the backbone of care.

Bracing for sport return can help selected athletes while neuromuscular control is rebuilt.

Persistent mechanical instability may lead to surgical stabilization discussion after a real rehab trial.

Do I need an x-ray after every sprain?

Not always. We use clinical rules and exam findings to decide when imaging changes immediate care.

Why does my ankle keep rolling?

Ligament laxity, weak peroneals, and poor balance strategies often combine. Rehab targets all three.

How soon can I return to sport?

When swelling is controlled, strength and hop testing look solid, and you trust the ankle under sport-specific demand.

Is PRP used for ankle sprains?

Not as routine first-line care. Most sprains are managed with progressive rehab; biologics are case-by-case if discussed at all.
