Artificial Turf vs Natural Grass Injuries: Which Surface is Safer for Sports Fields?

Why is the debate over turf vs. grass such a long-standing topic?

Since its introduction in the 1960s, “AstroTurf” has been widely adopted by sports venues, particularly the NFL, college sports, and school fields, due to its low maintenance and year-round use. However, the unfortunate news is that a specific condition known as “Astro Toe” has emerged, disrupting the once-peaceful situation.

Furthermore, sports like football, baseball, and rugby, which were almost all born on natural grass fields, have a natural affinity for them among players and fans. This has led to the safety debate over artificial turf vs. natural grass injuries.

According to Mark Cote of the Massachusetts General Hospital, “I think they’re right, and they certainly have good reason to blame artificial turf, but there are many reasons for injuries, and turf isn’t the only one.” “It’s a misconception to assume that natural turf is inherently better at preventing injuries than artificial turf, or vice versa.”

In this article, we will discuss the current state of artificial turf vs. natural grass, focusing not just on preference but also on performance, safety, and long-term sustainability. I hope this helps you choose the right lawn for your sports field.

Understanding Natural and Artificial Turf Sports Surfaces

Gazon naturel

Athletes often describe natural turf as soft, natural, and cooler in the sun, making it the ideal choice for sports. However, grass also has its drawbacks, including its susceptibility to weather (rainy days = muddy surfaces, hot days = dry surfaces), uneven growth that can lead to uneven, bumpy, or sunken surfaces, and the need for extensive maintenance, including irrigation, mowing, and ongoing repairs.

Gazon artificiel

Modern artificial turf designs offer a realistic natural grass appearance while also being more wear-resistant, durable, and consistent (for example, Herbe puissante uses high-density PE (polyethylene) materials and advanced production equipment to produce high-rebound yarns). Shock-absorbing pads are placed beneath the turf to better absorb impact. Installed sports turf is then filled with sand, rubber, or other environmentally friendly infill to stabilize the surface.

Unlike natural grass, artificial turf is all-weather resistant and maintains consistent performance regardless of climate.

What are Key Safety Considerations?

Player safety has always been a key point in the debate between artificial and natural turf. When comparing the safety of artificial and natural turf, it’s important to consider the conditions that affect athlete performance. Recent research highlights why this discussion remains so important.

Grip and Footwear: Natural grass becomes slippery in rainy conditions, reducing traction. Artificial turf offers relatively stable traction, but requires appropriate cleats (such as turf shoes or multi-purpose cleats).

Absorption des chocs : Grass itself can cushion falls, but an uneven surface can increase the risk of falls. FIFA artificial grass systems utilize ergonomically engineered shock-absorbing pads to manage impact and effectively protect joints.

Field Surface: Natural turf is prone to depressions and exposed areas, which can cause players to trip. Artificial turf remains smooth and predictable, reducing the risk of accidental slips.

Weather Resistance: Artificial turf is less susceptible to rain (mud) and drought (dry, hard surfaces). Even after heavy rain, turf fields can be used with confidence.

P.S. : A 2021-2022 NFL study reported a higher rate of lower extremity injuries on artificial turf (1.42 per game) than on natural turf (1.22 per game), and players injured on turf were significantly more likely to require season-ending surgery. Meanwhile, a 2023 meta-analysis in The Lancet found that professional football players had slightly lower overall injury rates on artificial turf, particularly for thigh and knee injuries. Non-contact lower extremity injuries are common in sports such as football, soccer, hockey, and lacrosse. These sports all involve sudden movements on artificial turf or grass surfaces. These sudden movements, including running, jumping, or cutting, place significant stress on athletes’ joints, potentially leading to injury.

How Field Design Helps Prevent Sports Injuries?

One of the biggest misconceptions is that injuries are solely caused by the surface of the field. In reality, whether using artificial turf or natural grass, a player’s injury risk depends not only on the field type but also on the quality, design, and ongoing maintenance of the turf system. Poorly designed or aging artificial turf systems can increase injury risk. How high-performance, FIFA-certified MightyGrass soccer fields are designed to prevent sports injuries?

Shock Absorption is Crucial

Studies have shown that fields with poor impact absorption increase the risk of concussions and lower-limb injuries. The MightyGrass system incorporates advanced, ergonomic shock-absorbing pads to reduce the risk of severe impact.

Balanced Grip Reduces Risk

Too much grip can cause joints to lock; too little grip can lead to dangerous slips and falls. Our patented monofilament yarn construction and padding system are designed to strike the right balance, ensures safe release during rapid movements.

Continuous Innovation: Recyclable, Temperature-Controlled Turf

Artificial turf can get very hot, but MightyGrass uses hollow fiber yarns and light-colored quartz sand or eco-friendly infill to reduce surface temperature and improve playing surface safety.

FIFA-certified Turf: Long-lasting and Durable

Unlike natural turf, which wears unevenly, MightyGrass artificial grass maintains consistent performance year-round, reducing the risk of unpredictable play and helping to prevent injuries over the long term.

MightyGrass Soccer Fields are built to international safety standards (FIFA, SGS, ISO) to ensure consistent performance. Combining sports science insights with innovative turf design, they help athletes play soccer with confidence on safer, more comfortable surfaces.

Maintenance and Long-Term Safety Tips:

If you use natural grass, regular watering, mowing, and fertilizing are necessary. Avoid surface inconsistencies on your soccer field, such as potholes and uneven areas, which can create unnecessary risks.

If you use an artificial turf surface, regular cleaning and brushing are required to keep the grass fibers upright. Regularly check and replenish fill to ensure the site is stable, reducing the risk of sudden changes in the site surface.

Conclusion

When comparing artificial turf and natural grass, there’s no single “perfect” answer. As Mark Cote says, many times, you can’t change the playing surface. But you can prepare your body for awkward or sudden movements. “Everyone wants to run faster, jump higher, and lift heavier,” Cote says. “If you look at athletes with longer careers, they tend to balance the strength required for their game with flexibility and other preventative measures.”

Artificial grass and sports grass soccer field surfaces each have their own advantages. Natural grass is highly dependent on weather and maintenance. Properly installed, artificial turf offers consistent, all-weather performance.

Player safety depends on quality design, certified systems, and proper maintenance, not just the choice between artificial and natural turf.

FAQ: Turf vs Grass Injuries

1. Are injuries more common on artificial turf than on natural grass?

Several systematic studies, including those by Venishetty N., indicate that the incidence of ankle/foot injuries on artificial turf may be higher than on natural grass. For example, in the NFL, the lower limb injury rate on artificial turf during the 2021–2022 season was 1.42 per game, compared to 1.22 per game on natural grass. Players injured on artificial turf were also more likely to require season-ending surgery. However, other studies have shown no significant difference in injury rates for knee and femur injuries between artificial and natural turf.

2. Why does artificial turf lead to more ankle/foot injuries?

Artificial turf fibers and studs provide a more stable and locked-in grip, but weaker release, placing additional torque on the ankle during sudden changes of direction or twisting movements.

Insufficient or unevenly distributed filler (rubber/sand) under the turf can also impair shock absorption and energy absorption, increasing injury risk. The higher temperature and greater rigidity of turf may also increase the risk of soft tissue impact during sliding or ground contact.

3. What types of injuries are more common on artificial turf?

Ankle/foot injuries (e.g., sprains and fractures) are more common.

Knee injuries (e.g., ACL and MCL) may be more common in high-level sports than on natural turf, especially during high-load, high-impact matches.

Bruise (“turf burn”), skin abrasions, and soft tissue scrapes are also more common on artificial turf, especially during sliding or falls.

Serious injuries (e.g., injuries requiring surgery or season-ending injuries) have been observed to be more common on artificial turf than on natural turf.

4. Is natural turf truly safer? What are its limitations?

Natural turf may lack grip when wet or muddy, making it easy to slip and fall.

Turf is prone to depressions, potholes, and uneven surfaces, which can create tripping and sprain risks. Natural turf can become hard and lose its cushioning properties in drought or extreme heat.

Maintenance costs (watering, mowing, reseeding, and repairing) are high, and the field is highly susceptible to weather.

5. Does research consistently support a higher incidence of injuries on artificial turf? Are there any conflicting findings?

A comparative analysis by Gould et al. (2023) found little difference in overall injury rates between artificial and natural turf, especially with modern, improved artificial turf. The only possible reason for this difference is the process used by artificial turf manufacturers and the artificial turf industry. Choosing a FIFA Quality and FIFA Quality Pro certified artificial turf manufacturer like MightyGrass ensures your field’s artificial turf surface is safe and reliable.

Different injury rates often reflect specific areas and specific sports levels, rather than being generalized across all sports and injuries.

6. How can design and maintenance reduce the risk of injury on artificial turf?

Ensure adequate and evenly distributed infill (rubber/sand/eco-infill) to maintain good shock absorption and stability.

Choose a high-standard turf system with a certified cushioning base, such as one that meets FIFA/SGS/ISO safety standards.

Regularly clean, comb, and refill the turf to maintain surface consistency.

Implement cooling measures (such as white padding, breathable fibers, and water spray) during hot weather.

Use the appropriate sole/stud type based on the sport and field conditions to avoid excessive grip or slippage.

Regularly inspect and replace aging or damaged turf components to prevent hardening and material fatigue.

7. Which surface has a higher risk of injury in soccer, football, or rugby?

In high-impact sports (such as American football and rugby), artificial turf may be more prone to sprains and injuries due to its high grip and rigidity. In sports like soccer that rely heavily on footwork and changes of direction, injuries are more likely to occur in the ankles and knees. The specific risk also depends on the athlete’s technique, speed, and field maintenance.

8. Does injury recovery take longer on artificial turf than on natural grass?

Studies have shown that injuries on artificial turf are more likely to be more severe, require longer recovery times, or be more likely to require surgery. For example, in an NFL study, players injured on artificial turf were more likely to undergo season-ending surgery.

9. Do new/third-generation/high-end artificial turf reduce injury risk?

Yes. Modern artificial turf designs prioritize cushioning, elasticity, fiber structure, and padding materials to closely mimic natural grass. However, even high-end artificial turf cannot completely eliminate all risks of excessive torque or grip. Performance compliance depends largely on manufacturer standards, installation quality, certifications (e.g., FIFA, ISO, SGS), and ongoing maintenance.

10. Are children/adolescents at higher risk of injury on artificial turf than adults?

Although direct comparative literature is limited, children/adolescents’ bones and ligaments are still developing and more sensitive to impact and torque.

Poor turf maintenance, insufficient padding, and environmental factors such as high temperatures can exacerbate the risk. Rigorous selection and maintenance standards are particularly important for youth sports.
