What are common ankle sprains in football or running?
Ankle sprains are among the most frequent injuries encountered in both football and running, accounting for a significant portion of sports-related medical consultations in the UK. These injuries occur when the ligaments that support the ankle joint are stretched beyond their capacity, often due to sudden changes in direction, uneven surfaces, or physical contact. While the symptoms of a sprain are generally similar, the specific type of sprain can vary depending on the movement that caused the injury. In football and running, the mechanics of the sport determine which ligaments are most at risk, and identifying the specific type of sprain is essential for a targeted and effective recovery.

Lateral (Inversion) ankle sprains
The lateral ankle sprain is by far the most common type of sprain in both football and running. It occurs when the foot rolls inwards, stretching or tearing the ligaments on the outer side of the ankle. The ligament most frequently affected is the anterior talofibular ligament (ATFL). In football, this often happens when a player is tackled or lands awkwardly after jumping for a header. In running, it is frequently caused by stepping on an uneven surface, such as a pothole or a loose stone on a trail. According to the NHS guide on sprains, lateral sprains typically cause immediate pain and swelling on the outer bony part of the ankle.
Medial (Eversion) ankle sprains
Medial ankle sprains are much less common than lateral ones because the ligaments on the inside of the ankle, known as the deltoid ligament, are significantly stronger. This injury occurs when the foot rolls outwards, stretching the inner ligaments. In football, a medial sprain might occur during a sliding tackle where the foot is forced outwards while planted on the ground. These injuries often take longer to heal than lateral sprains because the force required to damage the deltoid ligament is usually greater, often resulting in more extensive tissue damage.
High ankle sprains (Syndesmotic)
A high ankle sprain involves the ligaments that connect the two bones of the lower leg, the tibia and fibula, just above the ankle joint. These are known as syndesmotic ligaments. This injury is more common in football than in running because it is often caused by a twisting motion while the foot is firmly planted, or by a high-impact collision. High ankle sprains are considered more serious than standard sprains as they affect the stability of the entire lower leg. NICE clinical knowledge summaries indicate that these injuries usually require a longer period of immobilisation and a more cautious return to sport.
Football-specific injury risks
Football places unique demands on the ankle joint due to its multi-directional nature. Players must perform rapid accelerations, decelerations, and cutting manoeuvres where they change direction at high speed. These movements put immense lateral stress on the ankle ligaments. Additionally, the use of studded boots on grass or artificial turf can cause the foot to become stuck in the ground while the rest of the body continues to move, a common mechanism for both high ankle sprains and fractures. Statistics from UK sports registries show that ankle injuries account for approximately 10 to 15 per cent of all football-related traumas.
Running-specific injury risks
For runners, ankle sprains are often the result of fatigue or environmental factors. As a runner nears the end of a long session, the muscles supporting the ankle can become tired, reducing their ability to protect the ligaments from sudden rolls. Trail runners are at a particularly high risk due to the unpredictable nature of off-road terrain. Repetitive micro-trauma from running on cambered roads (surfaces that slope to the side) can also gradually weaken the ligaments, making a sudden sprain more likely. Unlike the high-impact collisions in football, running sprains are usually low-energy but can still result in significant grade 2 or 3 tears.
Grading the severity of the sprain
Regardless of whether the sprain occurred on the pitch or the pavement, UK healthcare providers use a three-grade system to assess the damage.
- Grade 1: Mild stretching of the ligament with microscopic tears. There is minimal swelling, and the joint remains stable.
- Grade 2: A partial tear of the ligament. This results in moderate pain, swelling, and bruising, with some joint looseness.
- Grade 3: A complete rupture of the ligament. The pain is severe, swelling is extensive, and the joint is unstable, often making it impossible to walk.
Conclusion
Ankle sprains in football and running are most commonly lateral, affecting the outer ligaments, though medial and high ankle sprains can occur in high-impact scenarios. Understanding the mechanics of how these injuries happen helps in both the immediate management and the prevention of future occurrences. Most minor ankle sprains heal well with rest and gradual rehabilitation, but more severe tears require professional assessment to ensure long-term joint stability. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
Why is my ankle still swollen weeks after a football injury?
Persistent swelling can occur if the injury was a high-grade sprain or if you returned to activity too quickly. It can also be a sign of internal scar tissue or chronic inflammation.
Can I run with a minor ankle sprain?
You should wait until the swelling has subsided and you have a full, pain-free range of motion. Running too early on a weakened ligament significantly increases the risk of a more severe re-injury.
Are high ankle sprains worse than regular ones?
Yes, they involve the ligaments that hold the leg bones together and generally require a much longer recovery time, often twice as long as a standard lateral sprain.
Do football boots protect against sprains?
While boots provide traction, they do not necessarily protect the ligaments. In some cases, long studs can actually increase the risk of a sprain if they catch in the turf during a twist.
How can I prevent ankle sprains when trail running?
Strengthening the calf muscles and performing proprioception exercises, such as standing on one leg, can help the body react more quickly to uneven ground.
Is it normal for a sprained ankle to click or pop?
Occasional clicking can be normal as scar tissue moves, but if the clicking is painful or accompanied by joint locking, you should seek medical advice.
Should I wear a brace for football after a sprain?
A brace can provide extra support during the initial return to play, but it should be used alongside strengthening exercises to ensure you do not become dependent on it.
