Lateral Ankle Ligament Reconstruction
What is lateral ankle ligament reconstruction?
Lateral ankle ligament reconstruction is a surgery to tighten and firm up one or more
ankle ligaments on the outside of your ankle. It’s also known as the Brostrom procedure.
It’s most often done as an outpatient surgery, so you can go home the same day.
Your ankle is a hinge joint that allows motion up and down, and from side to side.
Your foot and ankle have several ligaments. These are strong band-like structures
that keep the bones in your ankle and feet tightly connected. On the outer side of
your foot, you have several ligaments. These include the anterior talofibular ligament
(ATFL) and the calcaneofibular ligament (CFL). These help keep your ankle and foot
steady when you walk.
If you have had repeated ankle sprains or if you have certain foot deformities, your
ligaments can start to get weak and loose. If this happens, your ankle may become
During lateral ankle ligament reconstruction, the surgeon makes a small cut on the
outside of your ankle. This is done while you are under general anesthesia. Then your
surgeon tightens one or more of the ligaments on the outside of your foot.
Why might I need a lateral ankle ligament reconstruction?
You might need this surgery if one or more of the ligaments on the outside of your
ankle has loosened or stretched. This leads to a condition called chronic ankle instability.
It can cause chronic pain, repeated ankle sprains, and an ankle that often gives way
when you walk or perform activities.
At first, an ankle sprain may stretch and partially tear your ankle ligaments. This
first sprain makes it more likely that you will sprain your ankle again. This is more
likely if you did not have the first sprain treated properly. More sprains may loosen
your ligaments even more.
Certain mechanical problems with your foot can make you more likely to develop an
unstable ankle, such as:
Plantar flexion of the first ray
Midfoot cavus (high arches)
General looseness of your ligaments. For example, from a health condition such as
You may have already been treated with physical therapy and special foot inserts.
A healthcare provider may advise surgery if other treatments for your ankle haven’t
worked. It’s not common to need this surgery right after a first ankle sprain.
What are the risks of a lateral ankle ligament reconstruction?
Every surgery has risks. Risks for this surgery include:
Stiffness in your ankle joint
Complications from anesthesia
No improvement in your ankle stability
Your own risk for complications depends on your age, the anatomy of your foot, and
your general health. Talk with your healthcare provider about any concerns you might
have. You can discuss the risks that most apply to you.
How do I get ready for a lateral ankle ligament reconstruction?
Talk with your healthcare provider about how to prepare for your surgery. Ask if you
should stop taking any medicines ahead of time, like blood thinners. If you smoke,
try to stop smoking before your procedure. Tell your healthcare provider about all
the medicines you take. This included over-the-counter medicines like aspirin. Also,
tell him or her about any changes in your overall health, like a recent fever.
Before your procedure, you may need imaging tests, such as X-rays or an MRI. You should
not eat or drink anything after midnight the night before your procedure.
You may need to plan some changes to your home and activities before surgery. You
won’t be able to walk on your foot normally for a while.
What happens during a lateral ankle ligament reconstruction?
There are a number of methods used for lateral ankle ligament reconstruction. Ask
your healthcare provider about the details of your surgery. An orthopedic foot surgeon
will do your surgery. The surgery may take 2 or more hours. You can expect the following:
You will probably get general anesthesia to make you sleep through the procedure or
regional anesthesia to numb the involved leg.
During the surgery, your vital signs, like your heart rate and blood pressure, will
be watched carefully.
After cleaning the affected area, your surgeon will make a cut through the skin and
muscle of your ankle.
If your surgery is minimally invasive, your surgeon will cut a small incision. He
or she will put small instruments and a camera through the incision to perform your
Your surgeon may remove your ATFL and your CFL ankle ligaments from where they attach
on your fibula.
He or she may make these ligaments shorter.
Your surgeon may then reattach these ligaments to your fibula by using small holes
drilled into your bone and special suture.
Your surgeon may make other repairs, if necessary.
The layers of skin and muscle around your ankle will be surgically closed.
What happens after a lateral ankle ligament reconstruction?
Someone will watch you for a few hours after your surgery. When you wake up, you will
likely have a splint on your ankle. Often, lateral ankle ligament reconstruction is
an outpatient procedure. This means you can go home the same day. You should have
someone drive you home.
You will have some pain for a while after your surgery, especially for the first few
days. Pain medicines may help to relieve your pain. Carefully follow all instructions
about medicines and wound care. Keeping your leg elevated may help reduce swelling
and pain, too. You’ll probably need to use crutches and keep weight off your ankle
for at least a few weeks. Make sure to tell your surgeon right away if you have high
fever, chills, or increasing pain from your ankle.
You will need to return in about 10 days after your surgery to have your stitches
or staples removed. Your surgeon might also replace your splint with a boot or cast
at this time. In a few weeks, your healthcare provider will likely replace this cast
with a removable brace. You’ll need to use this brace for several months.
Your healthcare provider will give you specific instructions about how to strengthen
your ankle and leg muscles as you recover. You may benefit from physical therapy as
well. This will help make sure that your surgery will be a success.
