Ankle Ligament Reconstruction Surgery Recovery and Return to Sport

Most sprains heal without surgery. When the ankle keeps rolling despite months of rehabilitation, or when a severe sprain comes with other injuries such as cartilage damage or a torn tendon, surgery to repair or rebuild the ligaments may be needed.^[3] For the condition, see chronic ankle instability. This article covers what happens after the operation: ankle ligament reconstruction recovery, week by week, and how and when people get back to sport.

What results can you expect from ankle ligament reconstruction surgery?

The numbers are strong.

• Return to sport. In the review of 25 studies, 95% returned to some sport and 87% returned to competitive sport.^[1]
• Athletes do well. Professional and competitive athletes returned at a higher rate (93%) than recreational athletes (83%).^[1] In 343 professional athletes who had surgery for severe ligament tears, 89% returned to their pre-injury level, on average about 16 weeks after surgery.^[4]
• Durable repairs. The revision rate was 1.2% at an average of 8.4 years.^[2]
• Choice of method did not change return to sport. Arthroscopic or open surgery, repair or reconstruction, and early or late weight-bearing all gave similar return-to-sport rates.^[1]

Ankle ligament reconstruction recovery, week by week

After surgery, the ankle is usually protected in a cast or boot. Follow your surgeon’s instructions closely, because moving or loading the ankle too early can tear the repair. Rehabilitation then restores strength, motion and balance, and it can take weeks to months.^[3]

When can I walk after Broström surgery?

It depends on your repair and your surgeon. Some plans protect the ankle for several weeks. Others allow full weight right away: in one matched study after arthroscopic repair, an accelerated plan with immediate full weight-bearing and early strength and balance work gave function scores similar to a standard plan, with no recurrences.^[7]

Does suture-tape augmentation speed recovery?

Suture tape, sometimes called an internal brace, is a strong tape anchored to the bone alongside the repaired ligament. It is meant to protect the repair while it heals.^[8] Some surgeons add it, especially for active patients.

• A faster return in some studies. A 2026 review of 13 studies with 1,015 patients found better sports-function scores with suture tape. In the two studies that reported it, people returned to sport 4 to 8 weeks sooner.^[9]
• No cast needed in one trial. In a randomized trial of 61 patients, the suture-tape group needed no cast or brace right after surgery, which allowed early rehabilitation, and scored higher on sports activity (90 vs. 85 out of 100).^[10]
• Early rehabilitation held up. In 93 military patients with suture tape and an accelerated plan, 96% could hop on one leg at 6 weeks, and no repair failed.^[6]

Arthroscopic or open Broström?

The repair can be done through an open incision or through small incisions with a camera (arthroscopy). A 2026 review of 21 studies with 1,426 patients found less pain, higher function scores and a quicker return to daily work after arthroscopic repair than after open repair.^[11] Return-to-sport rates were similar either way.^[1] Arthroscopy also lets the surgeon look inside the joint and treat other problems. See ankle arthroscopy.

Why see a Foot and Ankle Surgeon early?

Over time, an unstable ankle can damage the bones and cartilage, and a severe sprain can come with other injuries, such as a torn tendon, that can be a reason for surgery.^[3] An evaluation by a surgeon sorts out what is loose and what else is injured. If your sprain still isn’t right, read why an ankle sprain may not be healing.

What are the limits?

Starting movement within 3 weeks gave better function scores, but also looser ankles on testing and more complications (11.4% vs. 3.1%) than starting later.^[5] Each decade of age raised the risk of not returning to sport by 6%, a higher body mass index also lowered the chance, and recreational athletes returned less often than competitive ones.^[1] An earlier review of 4 studies found no difference between suture tape and a standard repair in recurrence, function or complications.^[8] In the randomized trial, overall foot scores and daily-life function were the same with or without tape.^[10] After accelerated rehabilitation, people whose ligament looked poor on MRI before surgery had a higher risk of a weaker recovery.^[7] Most of this evidence comes from studies that looked back at past patients rather than large randomized trials.^[1,11]

Common questions

How long is recovery after ankle ligament reconstruction surgery?

Rehabilitation takes weeks to months.^[3] Across studies, the average return to sport was about 12 weeks.^[1]

When can I return to sport after a Broström repair?

On average about 12 weeks, and about 16 weeks in professional athletes, once strength and balance allow.^[1,4]

Is ankle ligament surgery worth it?

For an ankle that keeps giving way, the results are strong: 95% returned to sport and only 1.2% needed revision years later.^[1,2]

Is suture tape better than a standard Broström repair?

It may speed the return to sport and improve sports function. One earlier review found no clear difference, so ask whether it suits your ankle.^[9,8]

The bottom line

A Broström repair can turn an ankle you can’t trust into one that holds, and most people return to sport within months.
