Can Artificial Turf Increase Foot, Ankle & Achilles Injuries? A Foot & Ankle Surgeon Explains
By Dr. Sarang Desai — Fellowship-Trained Orthopedic Foot and Ankle Surgeon Sports Medicine | McKinney and Flower Mound, Texas
If you play or coach on turf, you've probably heard players say "turf beats up your body." As a foot and ankle surgeon who takes care of athletes, here's the honest version of what the research shows.
Overall injury rates on modern turf and grass are pretty similar. But when you zoom in on the foot and ankle specifically, the picture changes: artificial turf is the surface most consistently linked to more foot and ankle injuries — including ankle sprains, some ankle fractures, and Achilles problems. So the concern is real, but it's more specific than "turf is bad for everything."
Let me walk you through why this happens, what the numbers actually say, and — most importantly — what you can do about it.
Why Turf Might Hurt Your Foot and Ankle
The core issue isn't the green plastic grass itself. It's how your cleat interacts with the surface.
On natural grass, when you plant and cut hard, the grass and soil "give" a little. Your cleat can rotate and release from the ground. That release is actually protective — it lets your body slide out of a dangerous position instead of forcing a joint or tendon to absorb the full load.
On artificial turf, the surface grips your cleat more tightly and doesn't release as readily. Your foot stays planted while the rest of your body keeps rotating. That means more twisting force (torque) gets transmitted straight up through your foot, ankle, and Achilles tendon. Biomechanics studies describe this as higher rotational stiffness and peak torque at the shoe–surface interface, and when the infill compresses under your foot, you can also get higher peak forces and different loading rates than on grass.
Think of it this way: on grass your foot is wearing a valet that lets go; on turf, your foot is momentarily locked in a vise while your knee, ankle, and tendons pay the bill.
What the Research Actually Shows
The most comprehensive systematic review to date reviewed 53 studies spanning nearly 50 years. Its bottom line: most modern-turf studies found similar overall injury rates between turf and grass, but when researchers broke injuries down by body part, the foot and ankle stood out as the region most consistently injured more often on turf — true for both old-generation and new-generation turf. Knee and hip rates were generally similar, with the exception that elite football players may have somewhat more knee injuries on turf. Notably, the few studies that found grass to be worse than turf were all funded by the artificial turf industry.
A landmark NFL study looked at five seasons of standardized injury data across all 32 teams. It found play on synthetic turf produced a 16% increase in lower extremity injuries per play compared with natural turf. The effect was even stronger — and clearly significant — when the analysis focused on noncontact and surface-contact injuries, exactly the mechanism you'd expect if the surface itself were the problem. The authors concluded this supports a causal role for turf in lower-extremity injury.
A four-year Major League Soccer surveillance study is especially relevant to the foot and ankle. Overall injury rates were essentially equal between surfaces, but when they looked at specific categories, overall ankle injury, Achilles injury, and ankle fracture were all significantly more common on artificial turf. Other categories, like general foot and forefoot injuries, were no worse on turf.
To be fair, the evidence isn't all one direction. A large soccer meta-analysis actually found overall and even muscle-strain injuries were slightly lower on turf than grass — but that same body of work still flagged ankle injury as the exception, with an increased risk on third- and fourth-generation turf across multiple study groups. Rugby data likewise point to greater lower-limb injury severity and more foot/toe injuries on artificial surfaces.
So here's how I summarize it for my patients:
Question | What the evidence suggests |
Does turf cause more injuries overall? | Not really — overall rates are broadly similar on modern turf. |
Foot and ankle specifically? | Yes — this is the most consistent signal across studies. |
Ankle sprains? | Increased risk on turf across multiple studies. |
Achilles and ankle fractures? | Higher rates on turf in elite soccer data. |
Knee and hip? | Mostly similar, though elite football players may see more knee injuries. |
Muscle strains (calf, hamstring)? | Often similar or even slightly lower on turf. |
The Injuries I See Most From Turf
In a foot and ankle sports practice, the turf-related problems that walk through my door most often are:
Ankle sprains — the classic "rolled ankle" when the foot stays planted and the body twists over it. Repeated sprains can lead to chronic ankle instability.
Turf toe — a sprain of the big toe joint from the toe getting jammed into extension on a firm, grippy surface. It's named after turf for a reason. See my full turf toe guide.
Achilles tendon problems — from Achilles tendinitis and irritation up to a full Achilles tendon rupture, which typically happens on a hard push-off.
Ankle fractures — a twisting force with the foot locked can break the ankle. Details in my ankle fracture guide.
Fifth metatarsal / Jones fractures — the outer-edge foot bone that fails under repetitive cutting loads. See my Jones fracture guide.
Peroneal tendon injuries — the tendons on the outside of the ankle that get overloaded during cutting. See peroneal tendon injuries.
Cartilage / osteochondral lesions of the talus — bruises or divots in the ankle cartilage after a hard sprain. See osteochondral lesions of the talus.
Old Turf vs. New Turf: Does the Generation Matter?
Yes and no. The original AstroTurf-style carpet from the 1970s and 80s was essentially plastic over concrete, and injury rates were clearly higher. Today's third- and fourth-generation turf has long, grass-like fibers set in an infill of sand and rubber crumb, and it behaves much more like grass. That improvement is real and is a big reason overall injury rates have equalized.
But here's the catch: even with modern turf, the foot and ankle signal has not gone away. The systematic review found the higher foot-and-ankle rate persisted with new-generation turf. So the technology got better, but it didn't fully solve the specific problem of your foot getting stuck.
Two practical points I stress with athletes and parents:
Turf maintenance matters. Worn, under-infilled, or older turf grips harder and increases risk. A poorly maintained field is worse than the numbers suggest.
Switching surfaces may itself be a risk. Going back and forth between grass and turf without adjusting footwear appears to be a setup for injury.
The Cleat Factor — Often More Important Than the Turf
Patients fixate on the surface, but I spend just as much time talking about shoes, because that's the part you actually control.
Long, bladed studs give more grip and speed but are linked to higher injury risk because they don't release. Conical (rounded) studs release more easily and give more points of contact.
Match your cleat to your surface. Long molded or detachable studs are made for soft grass — on turf they can dig in and lock. On turf, a dedicated turf shoe or short-stud turf boot is usually the safer choice.
The wrong cleat on the wrong surface is one of the most modifiable risk factors there is.
Sport by Sport
The turf conversation looks a little different depending on what you play:
Football: The most data and the strongest concern. Elite football players may see more knee injuries on turf in addition to the foot-and-ankle signal. Turf toe is classically a football injury.
Soccer: Overall rates similar to grass, but ankle injuries, Achilles injuries, and ankle fractures run higher on turf in professional data. Cleat choice is huge here.
Rugby: Greater lower-limb injury severity and more foot/toe injuries reported on artificial surfaces.
Youth soccer: Interestingly, one study found youth players were more likely to be injured on grass — a reminder that footwear, conditioning, and field condition can outweigh the surface itself in kids.
Field hockey, lacrosse, baseball/softball turf infields, and multi-sport turf complexes: The same cleat–surface principles apply — plant-and-cut and hard push-off loads are the risk.
Basketball, pickleball, tennis, volleyball (indoor/court): These aren't cleat-on-turf sports, but the same push-off and cutting mechanics drive Achilles and ankle injuries; court surface and shoe wear matter more than "turf."
Common Misconceptions
"Modern turf is completely safe now." It's much better, but the foot-and-ankle risk specifically persists.
"Turf ruins your whole body equally." No — the strongest, most consistent signal is at the foot and ankle, not the knee or hip in most athletes.
"It's the plastic grass hurting me." It's really the cleat-surface grip and the forces that get transmitted up your leg — which is why your shoes matter so much.
"If I feel fine, the surface didn't do anything." Many turf-related injuries are cumulative overload (Achilles, stress fractures) that build over weeks, not a single dramatic moment.
How to Protect Your Feet and Ankles on Turf
You can't always choose the surface. You can control almost everything else:
Wear the right shoes for the surface. Turf shoes or short studs on turf; longer studs for soft grass. Don't use one pair for both.
Replace worn cleats. Flattened, uneven tread changes how your foot loads.
Warm up and build calf/ankle strength. Strong, flexible calves and ankles tolerate the extra torque far better — this is one of the best protections against Achilles and ankle injury.
Do ankle-stability and balance work, especially if you've sprained before. Old sprains that never fully rehabbed are a major reason people re-injure.
Manage load. Don't dramatically increase turf time overnight, and be cautious when switching between grass and turf.
Don't play through worsening Achilles pain or a "tweaked" ankle. Early, small problems on turf become surgical problems when ignored.
When to See a Foot and Ankle Specialist
Come in — or get seen promptly — if you have:
An ankle that keeps rolling or "gives way" (chronic instability).
A sudden pop or "I got kicked in the back of the leg" feeling with weakness pushing off (possible Achilles rupture — this is urgent).
Inability to bear weight after a twisting injury, or deformity/swelling suggesting a fracture.
Big-toe pain and swelling after jamming it into the turf (turf toe).
Pain on the outer edge of the foot that won't settle (possible fifth metatarsal stress or Jones fracture).
Nagging Achilles or ankle pain that isn't improving after a couple of weeks of rest.
The athletes who do best are the ones who get an accurate diagnosis early, before a manageable problem becomes a season-ending one.
The Bottom Line From My Chair
Artificial turf doesn't blow up every joint in your body — but if you're worried specifically about your feet, ankles, and Achilles, that concern is well founded. That's exactly the region where the research most consistently shows higher risk, and it's the region I treat every day. The good news is that most of the risk is manageable with the right footwear, smart training, and early attention to warning signs. Turf is a fact of life in Texas sports; getting hurt on it doesn't have to be.
Frequently Asked Questions
1. Does artificial turf really cause more injuries than grass?Overall injury rates on modern turf are similar to grass, but foot and ankle injuries specifically are more common on turf across most studies.
2. Why is turf worse for the ankle?Turf grips your cleat and releases it less than grass, so more twisting force is transmitted through the planted foot and ankle.
3. Is new turf safer than old AstroTurf?Much safer — modern infill turf behaves more like grass — but the increased foot-and-ankle risk still persists even on new turf.
4. Does turf increase Achilles injuries?Elite soccer data found significantly higher Achilles injury rates on turf, and the hard push-off mechanics of turf plausibly explain it.
5. Does turf cause Achilles ruptures?Turf is associated with more Achilles injuries; ruptures typically happen during a forceful push-off, which turf's grip can accentuate.
6. What is turf toe?A sprain of the big toe joint from the toe being forced into extension on a firm surface — classically seen on turf, hence the name.
7. Are ankle sprains more common on turf?Yes. Increased ankle sprain risk on artificial turf is one of the most consistent findings in the literature.
8. Does turf increase the risk of ankle fractures?Professional soccer surveillance found higher ankle fracture rates on turf, likely from the foot locking during a twist.
9. What about knee and ACL injuries?Most studies show similar knee rates between surfaces, though elite football players may have somewhat higher knee injury rates on turf.
10. Do muscle strains happen more on turf?No — calf and hamstring strains are often similar or even slightly lower on turf compared with grass.
11. Is turf more dangerous for kids?Not necessarily. One youth soccer study actually found more injuries on grass; footwear, conditioning, and field condition matter more in kids.
12. Should my child avoid turf fields?No blanket avoidance is needed — proper cleats for the surface, good conditioning, and ankle strength matter far more.
13. What cleats are safest on turf?Dedicated turf shoes or short-stud boots that release easily. Long, bladed studs meant for soft grass are riskier on turf.
14. Can I wear my grass cleats on turf?It's not ideal. Long molded studs can lock into turf infill and increase twisting forces on the foot and ankle.
15. Does the condition of the turf matter?Yes. Worn, under-infilled, or older turf grips harder and increases risk, which is why field maintenance is important.
16. Is switching between grass and turf risky?Switching surfaces has been suggested as a risk factor, so give your body time to adjust and match footwear to each surface.
17. Does turf cause stress fractures?Evidence is limited; one study found similar stress fracture rates between surfaces, though repetitive cutting load can contribute.
18. Why do NFL players complain about turf?NFL data show a 16% higher lower-extremity injury rate on synthetic turf, especially for noncontact injuries — so the complaints have data behind them.
19. If turf is riskier, why do leagues use it?Turf is cheaper to maintain, playable in all weather, and usable far more hours per week than grass.
20. Are the "turf is safer" studies trustworthy?Be cautious — the systematic review noted that studies finding grass worse than turf were all funded by the turf industry.
21. Is indoor turf different from outdoor turf?The same cleat–surface principles apply; grip, infill, and shoe choice drive risk more than indoor vs. outdoor.
22. How can I lower my own risk on turf?Right shoes for the surface, strong flexible calves and ankles, balance training, gradual load increases, and not playing through pain.
23. Does ankle taping or bracing help on turf?Bracing can help, especially if you have a history of sprains or instability, by limiting extreme ankle motion.
24. I sprained my ankle on turf and it keeps happening — is that normal?Recurrent giving-way suggests chronic ankle instability, which is treatable and worth evaluating.
25. How do I know if it's turf toe or a broken toe?Both cause pain and swelling; imaging and an exam distinguish them, so get evaluated if you can't push off normally.
26. Can turf injuries be career-ending?Some — like a neglected Achilles rupture or a mismanaged Jones fracture — can be serious, which is why early care matters.
27. Should Achilles pain on turf make me stop playing?Worsening Achilles pain should not be pushed through; early treatment prevents it from becoming a rupture or chronic problem.
28. Do women have higher turf injury rates than men?Large soccer meta-analysis data showed a similar pattern for both men and women, with overall rates comparable to grass.
29. Does turf affect recovery after foot or ankle surgery?Return to turf should be guided by strength, stability, and confidence — not just time — and often benefits from proper footwear and bracing.
30. When should I see a foot and ankle surgeon after a turf injury?See a specialist for inability to bear weight, a pop with push-off weakness, recurrent giving-way, deformity, or pain not improving in a couple of weeks.

LinkedIn Post:"Turf causes more injuries" is a headline that deserves nuance. The best current evidence shows overall injury rates on modern third- and fourth-generation turf are broadly comparable to natural grass — but foot and ankle injuries specifically remain higher on turf, and elite football and soccer data show increased ankle, Achilles, and lower-extremity injury rates. The likely driver is reduced cleat release and higher rotational load transmitted to the distal limb.
