Repeated Ankle Sprains: Why They Keep Happening and How to Prevent Them
“I’ve sprained this ankle so many times I’ve lost count.”
We hear some version of that sentence most weeks in the clinic. It usually comes from someone who isn’t currently doubled over in pain. Their ankle has just gone over again, on a curb, on the stairs, on the court, somewhere ordinary, and they’re starting to wonder if something is properly wrong with it.
If that sounds familiar, you’re not imagining it and you’re not being dramatic. An ankle that keeps rolling is telling you something specific, and it’s rarely fixed by waiting for the next sprain to settle down on its own. Here’s what’s actually going on, and what to do about it.
Who This Affects, and What It Actually Feels Like
We see this pattern most often in two kinds of patients. The first are people who play sports involving sudden changes of direction, basketball, netball, soccer, touch football, where the ankle has to stabilise under load dozens of times a match. The second are people who had one bad sprain years ago, treated it with rest and not much else, and have been managing a slightly unreliable ankle ever since.
The description patients give us is fairly consistent. There’s often a dull, achy stiffness that lingers between sprains rather than sharp pain, and many describe the ankle feeling loose or untrustworthy on uneven ground.
There’s also usually a specific moment patients remember: the joint suddenly gives way, sometimes with a small pop, before the pain kicks in. Swelling tends to flare after activity and settle again within a day or two, which is part of why people put off getting it checked.
What’s Actually Going On
Repeated ankle sprains are almost never bad luck. They’re usually the downstream result of one or more of the following.
The Ligaments on the Outside of the Ankle Stay Loose
Most rolled ankles involve the same structure: the anterior talofibular ligament, or ATFL, a band of tissue on the outer ankle that stops the foot rolling too far inward. Each time it’s stretched or partially torn, it can heal slightly longer than it started, a bit like an elastic band that never quite snaps back.
Over several sprains, that laxity adds up. The ankle simply has less mechanical resistance to rolling the next time it’s put in an awkward position.
The Ankle’s Early Warning System Gets Quieter
Ligaments do more than hold bones together. They’re packed with tiny nerve receptors that constantly report the ankle’s position back to the brain, a sense clinicians call proprioception (your body’s awareness of joint position without needing to look).
Damage these receptors enough times and that feedback loop gets slower and less accurate. The brain gets less warning that the ankle is about to roll, and less time to fire the muscles that would normally stop it.
The Muscles That Should Catch You React Too Slowly
The peroneal muscles, running down the outside of the lower leg, are the ankle’s main defence against rolling inward. In a healthy ankle they fire almost instantly to correct the joint before it goes too far.
After repeated sprains, that reaction time and strength often lag, particularly if strengthening was never part of the original rehab.
An Earlier Sprain That Was Never Fully Rehabbed
This is the one we see most. Someone sprains an ankle, rests it, ices it, and gets back to sport once the swelling has gone down, without ever restoring balance, strength, or full range of motion first. The ankle looks recovered on the outside, but the underlying weakness is still there, waiting for the next uneven step.
One nuance worth knowing: not every ankle that “gives way” is mechanically loose. Sometimes the ligaments have healed at a normal length, and it’s purely the proprioceptive and strength side of the equation that hasn’t caught up. Telling the two apart changes what the rehab plan needs to prioritise, which is part of why a proper ankle assessment matters more than guessing.
What It’s Often Mistaken For
Because “rolled ankle” covers a lot of ground, a few other conditions can hide behind the same story. Peroneal tendon injuries, where the tendons running behind the outer ankle bone become irritated or unstable, can feel almost identical to ligament laxity.
A high ankle sprain, involving the ligaments higher up between the two lower leg bones, needs a different rehab approach entirely and is easy to miss if only the outer ligaments are examined. Less commonly, a small chip of cartilage or bone can be dislodged inside the joint during a bad sprain, which is one reason persistent swelling or catching in the joint deserves a proper look rather than being written off as just another sprain.
Red Flags: When to See a Doctor Right Away
Most repeated sprains are mechanical and manageable, but a few signs mean you should get seen urgently rather than waiting it out:
Visible deformity of the ankle or foot
Inability to bear any weight at all, immediately after the injury
Numbness, tingling, or a cold, pale foot
Bruising and swelling that extends well beyond the ankle joint itself
Pain that keeps getting worse over the following days rather than easing
If any of these apply, seek urgent medical attention and imaging rather than trying to manage it at home.
What to Do in the First 48 to 72 Hours
If you’ve just rolled your ankle again and can’t get in to be assessed straight away, a few things generally help in the meantime:
Protect the joint and keep weight off it as much as comfortable, without fully immobilising it for days on end
Ice for short periods to help manage swelling
Gentle compression, such as a firm bandage, to limit how much the joint swells
Elevating the foot above heart height when resting
Moving the ankle gently within a pain-free range rather than keeping it completely still
Avoid pushing back into sport or heavy activity until it’s been properly assessed, even if the swelling looks like it’s settling. That’s usually the point where people re-injure it.
How We Treat It: Assessment Through to Return to Sport
The Initial Assessment
When someone comes in with a history of repeated sprains, the first session focuses on working out which of the mechanisms above is actually driving it, rather than treating every ankle the same way. That typically includes ligament stability testing, a look at balance and proprioception, and a movement assessment of how the ankle behaves during single leg standing, hopping, and change of direction. Our physiotherapy and chiropractic team are looking for the pattern behind the sprains, not just treating this one in isolation.
Hands-On Treatment
Depending on what that assessment finds, treatment might include joint mobilisation to restore full ankle range of motion, active release technique through the peroneals and calf, and dry needling for muscles that have become chronically tight from compensating.
Short-term taping or bracing is sometimes used while the underlying strength and balance work catches up, though it’s a temporary support rather than the long-term fix.
The Recovery Timeline
A typical rebuild looks something like this:
Weeks 1 to 2: calming swelling and pain, restoring pain-free range of motion, and beginning gentle balance work as tolerated
Weeks 2 to 6: progressive strengthening of the muscles around the ankle, alongside more demanding balance and proprioceptive drills
Weeks 6 to 12 and beyond: sport-specific retraining, including cutting, pivoting, and landing mechanics, before a graded return to full training and competition
Evidence backs up why that middle stage matters so much. A review pooling multiple randomised trials found that proprioceptive and balance training meaningfully reduces the risk of another ankle sprain, with the effect holding up specifically in people who’d already sprained the joint before.
Skipping straight from pain-free back to sport, without that phase, is one of the most common reasons an ankle keeps going over.
Do You Need a Scan or Surgery?
Usually not. Most repeated sprains can be assessed clinically through ligament testing, movement analysis, and a detailed history, without imaging. Clinicians often use a set of guidelines called the Ottawa Ankle Rules to work out whether an x-ray is genuinely needed after an acute injury, which has meaningfully cut down on unnecessary scans.
An MRI is occasionally warranted if there’s suspicion of cartilage damage, a tendon tear, or if instability persists despite several months of well-structured rehab. Surgery to tighten or reconstruct the lateral ligaments is available and can be very effective, but it’s reserved for a small minority of cases where conservative treatment genuinely hasn’t worked, not the first line of treatment for a handful of repeated sprains.
Staying Pain Free For Good
The single biggest reason ankles keep rolling is going back to normal activity as soon as the pain settles, without addressing the strength, balance, and proprioception that were lost along the way.
This is genuinely common. Research suggests as many as 46 percent of people with a history of ankle sprain go on to develop some form of ongoing instability, largely because that underlying rebuild never happens.
Ongoing balance and strength work, even briefly a few times a week once you’re back to full activity, is what keeps the gains from rehab in place. For people in sports with a lot of cutting and jumping, supportive taping or a brace during higher-risk periods (pre-season, returning from a break, playing on an unfamiliar surface) is a reasonable extra layer, though it’s not a substitute for the underlying strength work.
If your ankle has become part of the furniture, something you just expect to give way occasionally, that’s worth changing. Book an assessment with our team, and we’ll work out exactly which of the mechanisms behind repeated sprains applies to you, and build a plan to stop it becoming a permanent pattern.
FAQ
How many times can you sprain the same ankle before it’s a real problem?
There’s no strict number, but if you’ve sprained the same ankle more than once or twice, or it regularly feels unstable on uneven ground, it’s worth a proper assessment rather than waiting for a bigger sprain to prompt one.
Can a sprained ankle heal on its own without treatment?
A single mild sprain often improves with basic self care, but the strength and balance side of recovery generally needs deliberate rehab. That’s the piece most commonly missed, and it’s usually why sprains repeat.
Do I need to wear a brace forever if I keep spraining my ankle?
Not usually. Bracing can help during higher-risk periods while the underlying strength and balance work is being rebuilt, but the goal of treatment is a stable ankle that doesn’t depend on external support long-term.
Is it normal for my ankle to still feel stiff weeks after a sprain?
Some lingering stiffness for several weeks is common, particularly if range of motion work wasn’t part of the initial recovery. Stiffness that persists well beyond that, or that’s getting worse, is worth having looked at.
What’s the difference between a sprain and a break?
Both can cause similar pain and swelling, which is exactly why clinical testing matters. A break usually involves point tenderness directly over bone and difficulty bearing any weight at all, but the only reliable way to tell them apart is a proper examination, with an x-ray if the findings point that way.
Can physio or chiro actually stop my ankle from rolling again?
In most cases, yes. Structured rehab targeting strength, balance, and proprioception has consistently been shown to reduce the risk of another sprain, particularly for people who’ve already had one before.
