Common Football Injuries: Ankle, Knee, Hamstring and Groin

Football places enormous demands on the lower limbs.

Players sprint, tackle, kick, jump, land, accelerate, decelerate and change direction repeatedly, often while reacting to opponents and the ball.

It is therefore unsurprising that lower-limb injuries make up a large proportion of the problems seen in football.

But not all football injuries are the same.

An ankle sprain, hamstring strain, ACL injury and adductor-related groin problem involve very different tissues and require different rehabilitation.

This guide looks at some of the most common football injuries, what they may feel like and what players generally need to rebuild before returning to the pitch.

For the broader question of reducing injury risk across a season, see our guide to How to Prevent Football Injuries: What Actually Matters?

Ankle Sprains in Football

Ankle sprains are among the most familiar injuries in football.

They can occur when a player:

• Lands on another player's foot.
• Changes direction awkwardly.
• Is tackled while the foot is planted.
• Loses balance during a landing.

The most common presentation involves the lateral ligaments on the outside of the ankle, although footballers can also sustain higher ankle or syndesmosis injuries and less common medial ankle injuries.

Why Recurrent Ankle Sprains Matter

The first ankle sprain is not always the end of the problem.

After an injury, a player may regain the ability to walk and jog relatively quickly while still having deficits in:

• Calf strength.
• Balance.
• Proprioception.
• Hopping.
• Landing.
• Change of direction.
• Confidence.

These qualities matter because football asks far more of an ankle than straight-line jogging.

Football Ankle Rehabilitation

Rehabilitation may progress through:

• Restoring comfortable movement.
• Calf and ankle strengthening.
• Single-leg balance.
• Hopping.
• Landing.
• Accelerating and decelerating.
• Changing direction.
• Reactive football drills.

Bracing or taping may also be useful for some players, particularly those with previous recurrent ankle sprains.

Our Foot & Ankle Physiotherapy service provides more information about assessment and rehabilitation of these injuries.

ACL Injuries in Football

Anterior cruciate ligament injuries are less frequent than simple ankle sprains, but their consequences can be much greater.

ACL injuries commonly occur during rapid deceleration, change of direction or landing, sometimes without another player directly contacting the knee.

Contact ACL injuries can also occur.

A player may describe:

• A sudden giving-way sensation.
• A pop at the time of injury.
• Rapid swelling.
• Difficulty continuing to play.
• A sense that the knee is unstable.

Not every ACL injury presents identically, so clinical assessment and appropriate imaging are often needed.

Does Every ACL Injury Need Surgery?

No.

Management depends on the individual, associated injuries, knee stability and the activities the person wants to return to.

Some people choose ACL reconstruction, while others can successfully follow a non-operative rehabilitation pathway.

The decision should be individual rather than assuming reconstruction is inevitable.

Returning to Football After ACL Injury

Whether treatment is surgical or non-surgical, football rehabilitation needs to rebuild far more than basic knee movement.

Players generally need to progressively restore:

• Quadriceps strength.
• Hamstring strength.
• Calf strength.
• Running.
• Jumping.
• Landing.
• Sprinting.
• Deceleration.
• Change of direction.
• Football-specific fitness.
• Confidence.

Our ACL & Meniscus Rehabilitation and Return to Sport pathways use progressive testing and football-specific exposure to bridge the gap between rehabilitation and competition.

Other Knee Injuries in Football

Not every football knee problem is an ACL injury.

Players may also experience:

• Meniscus injuries.
• Medial collateral ligament injuries.
• Patellofemoral pain.
• Patellar tendon pain.
• Other traumatic ligament injuries.

The treatment depends heavily on the diagnosis.

A contact MCL injury requires a different approach from gradual anterior knee pain that develops during training.

Our Knee Physiotherapy page provides a broader overview.

Hamstring Strains in Football

Hamstring strains are among the most important muscle injuries in football.

They commonly occur during high-speed running and sprinting.

The player may experience:

• A sudden pain in the back of the thigh.
• A grabbing or tearing sensation.
• Pain when trying to continue sprinting.
• Tenderness after the injury.
• Reduced strength.

The severity can range from relatively minor strains to significant injuries requiring a prolonged rehabilitation period.

Why Sprinting Matters in Hamstring Rehabilitation

A player can become comfortable doing hamstring curls long before the hamstring is ready for maximal sprinting.

This is an important distinction.

As running speed increases, hamstring demands rise substantially.

Returning to football therefore requires progressive exposure to speed.

A rehabilitation pathway may include:

• Early hamstring loading.
• Progressive strengthening.
• Running.
• Acceleration.
• High-speed running.
• Near-maximal sprinting.
• Repeated sprint exposure.
• Football-specific drills.

Being able to jog pain-free is not the same as being ready to sprint in the 85th minute of a match.

Can Nordic Hamstring Exercises Help?

Yes, Nordics can be useful.

Programs incorporating Nordic hamstring exercise have strong evidence for reducing hamstring injury rates in football populations.

But Nordics are not the only thing that matters.

A football hamstring program may also use hip-dominant strength exercises, knee-flexion exercises and sprint exposure.

Groin Pain in Football

Groin pain is particularly relevant in football because of repeated kicking, sprinting and changing direction.

Importantly, the groin is a region rather than one specific anatomical structure.

Symptoms may be related to:

• Adductor muscles or tendons.
• Iliopsoas and other hip flexors.
• The inguinal region.
• The pubic region.
• The hip joint.

More than one structure can sometimes contribute.

This is why describing every football groin problem as a simple “groin strain” can be misleading.

Adductor-Related Groin Pain

The adductors are heavily involved in football.

They contribute during:

• Kicking.
• Acceleration.
• Sprinting.
• Cutting.
• Side-stepping.
• Reaching for the ball.

Adductor strengthening is therefore commonly included in both rehabilitation and football preparation.

Copenhagen adduction exercises are one popular option and are effective for improving adductor strength.

They are not, however, a magic exercise that independently prevents every groin injury.

The broader goal is to build enough groin capacity for the demands of the player.

When Should Groin Pain Be Assessed?

Assessment becomes particularly useful when:

• Pain persists for more than a short period.
• Kicking becomes increasingly uncomfortable.
• Sprinting or changing direction is limited.
• The pain keeps returning.
• There is significant loss of hip movement.
• The diagnosis is unclear.

Our Hip & Groin Physiotherapy service can help determine which presentation best fits the symptoms.

Calf Injuries in Football

Calf strains can occur during acceleration, sprinting, jumping and repeated changes of pace.

They can sometimes be underestimated because players may regain comfortable walking fairly quickly.

Football requires much higher calf capacity than walking.

Rehabilitation may need to restore:

• Straight-knee calf strength.
• Bent-knee calf strength.
• Running capacity.
• Hopping.
• Acceleration.
• Sprinting.

Overuse Injuries in Football

Not all football injuries occur during one obvious moment.

Players can also develop gradual-onset problems such as:

• Patellar tendon pain.
• Achilles tendon pain.
• Anterior knee pain.
• Shin pain.
• Bone stress injuries.
• Persistent groin pain.

These presentations often require us to understand changes in training load alongside local strength and tissue capacity.

Football Injuries in Junior Players

Junior footballers are not simply smaller adults.

Growth and maturation create additional considerations.

During periods of rapid growth, young players may experience changes in coordination, strength and load tolerance.

Growth-related presentations around the heel or knee can also occur.

The aim should be to keep young players active wherever possible while adjusting the load or activity when necessary.

Our Kids Sports Physiotherapy service works specifically with these presentations.

Why Previous Injury Matters

Across football injuries, one recurring theme is the importance of what happened previously.

A player may feel recovered but still have meaningful deficits in strength, running or sport-specific capacity.

For example:

• An ankle sprain may leave reduced calf capacity.
• An ACL injury may leave substantial quadriceps deficits.
• A hamstring strain may leave inadequate sprint exposure.
• A groin injury may leave reduced adductor strength.

This is why rehabilitation should consider what football requires rather than stopping as soon as pain improves.

Can These Football Injuries Be Prevented?

Not completely.

But injury risk can be reduced.

Strength training, progressive sprint exposure, structured neuromuscular warm-ups, landing and deceleration training, and appropriate rehabilitation of previous injuries can all contribute.

Rather than repeating all of that here, we cover it in detail in our main guide:

How to Prevent Football Injuries: What Actually Matters?

Different Injuries Need Different Rehabilitation

The key message is that there is no single football rehabilitation program that works for every injury.

An ankle sprain needs a different progression from an ACL injury.

A hamstring strain requires different high-speed preparation from persistent groin pain.

What they share is the need to restore enough physical capacity for football.

If an injury is limiting your training or you are unsure whether you are ready to return to competition, our Football Physiotherapy, Sports Physiotherapy and Return to Sport services can help build a plan around your injury and the demands of your game.
