When Does an Ankle Ligament Tear Require Surgery?

Many torn ankle ligaments heal well with a brace and physiotherapy. Ankle ligament tear surgery becomes an option when the ankle keeps giving way after a fair rehab programme, or when scans show other damage inside the joint. A foot and ankle surgeon can tell you which applies to you.

You rolled your ankle on the soccer pitch, the badminton court or a kerb. The swelling settled. The pain faded. Then, a few weeks later, it rolled again.

If that sounds familiar, this guide is for you. At OrthofootMD in Singapore, Dr Gowreeson Thevendran treats ankle ligament injuries through Island Orthopaedics, at Mount Alvernia Hospital and Mount Elizabeth Novena Specialist Centre.

Ankle ligament tear surgery is a real option for some people, and a long way off for others. Below, we explain how ligament tears are graded, what treatment starts with, the signs of chronic ankle instability and when an ankle doctor’s opinion pays off.

Doctors grade ligament injuries from 1 to 3. Grade 1 is a mild stretch. Grade 2 is a partial tear. Grade 3 is a complete tear.

The grade guides early care. How the ankle behaves over the following months guides the surgery decision.

The anterior talofibular ligament (ATFL) on the outer side of the ankle is usually the first to tear. The calcaneofibular ligament (CFL) sits just below and behind it and can tear in more severe twists.

A twist that damages the ligaments above the joint is called a high ankle sprain. It behaves differently and needs its own assessment.

Torn ankle ligament treatment starts with protection and early, guided movement. Long periods of strict rest can leave the joint stiff and weak.

Care typically includes:

• A brace, tape or walking boot, chosen to match the severity
• Ice, compression and elevation to settle swelling
• Physiotherapy to restore movement, strength and balance
• A graded return to walking, running and sport
• Platelet-rich plasma (PRP) injections in selected cases, discussed with your specialist (the evidence for PRP in ankle ligament injuries is still developing)

Ankle sprain recovery varies with the grade. A mild sprain may feel settled within a few weeks. A complete tear takes longer.

Balance training deserves a place in every plan. A torn ligament also dulls the ankle’s sense of position, so single-leg balance work on a soft surface retrains the joint to react in time.

Chronic ankle instability means the ankle keeps giving way after an injury, and confidence in the joint stays low. It often shows up in small moments on uneven ground.

Check yourself against this list:

• The ankle rolls on stairs, kerbs or a slightly uneven path
• It gives way when you change direction on court or pitch
• Swelling or aching returns after activity you used to handle
• You brace or tape it for ordinary walks because it feels unsafe
• You scan the ground before every step
• Minor twists keep turning into full sprains

Repeated sprains deserve attention. Each episode can add stress to the cartilage and tendons around the joint.

Chronic ankle instability treatment begins with the same structured rehab and bracing described above. Surgery enters the picture when that effort has run its course.

Ankle ligament tear surgery becomes an option when the ankle keeps giving way after a committed rehab programme or when imaging shows damage that rehab cannot repair. Active people reach this point sooner, because their ankles face demanding movements week after week.

Use this check before your appointment. It is a rule of thumb, and your specialist makes the final call.

1. Is the ankle still giving way? Count the episodes since your rehab began.
2. Has rehab had a fair run? That means several months of supervised physiotherapy, with bracing where needed.
3. Is anything else damaged? Cartilage, tendons or scar tissue inside the joint can cause pain that physiotherapy cannot fix.

A yes to the first two questions is the usual cue to discuss surgery. A yes to the third can bring that discussion forward.

• A peroneal tendon tear alongside the ligament injury
• Cartilage damage on the joint surface (an osteochondral lesion)
• Scar tissue or bone spurs that pinch the joint (impingement)
• A high ankle sprain with an unstable joint
• A fracture that also involves ligament injury

A fresh, complete tear in a high-level athlete is sometimes a case for early surgery. That call belongs to a specialist who has examined the ankle and reviewed the scans.

See an ankle doctor if you have sprained the same ankle more than once or if it still feels unstable after several weeks of care. Seek review sooner if any red flag appears.

See an ankle doctor if you have sprained the same ankle more than once or if it still feels unstable after several weeks of care. Recognising the signs that a foot injury needs medical attention can help you avoid delaying an assessment when pain, swelling or difficulty bearing weight persists.

Book an assessment when:

• Sprains keep recurring in the same ankle
• Pain sits deep in the joint long after the injury
• Your ankle sprain recovery has stalled, or your confidence in the joint has dropped

Get an urgent medical review if:

• You cannot put weight on the foot
• There is severe pain over the bone
• The ankle looks out of shape
• The foot feels numb, cold or pale

A foot and ankle surgeon reads these injuries every day. Dr Gowreeson Thevendran is a triple-fellowship-trained orthopaedic and trauma surgeon, and foot and ankle conditions are the primary focus of his practice.

At the assessment, the team examines the ankle and uses digital radiography or 3D imaging. Further scans such as MRI follow when they will change the plan.

Where suitable, we favour keyhole techniques. They use small incisions and aim to speed recovery and limit scarring. A keyhole look inside the joint can sometimes reveal cartilage or scar tissue problems that scans miss. Ankle surgery for ligament injury usually follows one of two paths:

• Ligament repair: the surgeon tightens and reattaches your own stretched ligament, sometimes with added reinforcement.
• Ligament reconstruction: a tendon graft rebuilds the ligament when the original tissue is too weak or damaged to repair.

Other problems found in the joint can often be treated in the same operation. Live X-ray imaging (fluoroscopy) during surgery helps confirm that the repair sits correctly.

Recovery moves through stages. Your surgeon sets the pace with you.

Protection. A boot or brace shields the repair while early movement is guided.

Movement. Physiotherapy restores range and settles swelling.

Strength and balance. The ankle rebuilds the control that the injury took away.

Return to sport. Soccer players and runners follow a sport-specific pathway. Strength, balance and hop-test results guide the timing, and the calendar is only a rough guide.

Full recovery after ankle ligament tear surgery typically takes several months. Like any operation, ankle surgery carries risks, including infection, stiffness, nerve irritation and, sometimes, recurring instability. Your surgeon explains them before you decide.

An ankle that keeps giving way is sending a message. The answer may be a sharper rehab plan or ankle ligament tear surgery, and a clear diagnosis comes first.

If your ankle still feels unreliable, bring your answers to the three questions and schedule an assessment with our foot and ankle specialist in Singapore. We will examine the ankle, review your scans and map out a plan that fits your goals.
