Pain at the front of the thigh is also known as anterior thigh pain. Here we explain the common causes, as well as some less common causes which should not be missed.
Sudden onset anterior thigh pain
The following injuries tend to occur suddenly where you will know as specific point in time it occured:
Quadriceps strain (thigh strain)
A thigh strain or quadriceps strain is a tear in one of the quadriceps muscles at the front of the thigh. It can range from mild discomfort to a full-blown tear of most of the muscle, resulting in severe pain and inability to walk. Symptoms typically include:
- Sudden sharp pain at the front of the thigh.
- Bruising may appear later.
- Strains are graded 1 to 3 depending on how bad the injury is.

Quadriceps contusion (thigh contusion)
A dead leg, also known as a charley horse is a bruise or contusion caused by a direct impact to the leg, crushing the muscle against the femur (thigh bone) resulting in swelling and sometimes bruising of the thigh muscles.
- Pain at the time of injury.
- Restricted movement in your leg/muscle.
- Swelling and later bruising may appear over time.
Thigh contusions range in severity from very mild which is hardly noticeable at the time, to severe injuries where you are unable to walk. Heat or massage should not be applied during the acute phase as this may lead to bone growth within the muscle (Myositis ossificans.

A traumatic femur fracture is a serious and usually fairly obvious injury caused by accident or severe impact.
- The patient will feel severe pain in the thigh.
- There may be deformity in the thigh, for example, the leg may be at an angle or the injured leg appearing shorter than the other.
- A considerable amount of swelling may be visible and the patient will be unable to move their leg.

Rectus femoris tendon strain/avulsion
These cause pain at the top of the thigh/front of the hip where the tendon of the powerful rectus femoris muscle originates.
- Rectus femoris tendon strain – this is a tear or the rectus femoris tendon.
- Rectus femoris tendon avulsion – this occurs the tendon tears at the point of attachment pulling a fragment of bone with it.
They can be difficult to distinguish so if you suspect an avulsion injury seek professional medical advice and imaging.
Other muscle strains in the thigh include; Sartorius muscle strain & Gracilis muscle strain.
Gradual onset anterior thigh pain
The following injuries tend to occur gradually over time through overuse, or from an acute injury which has not healed properly”
Myositis ossificans occur as a complication of not treating a contusion correctly. It involves a small growth of bone within the muscle. Symptoms include:
- Muscle pain, particularly during exercise.
- Restricted range of movement.
- A hard lump may be felt deep in the muscle.
- An X-ray can confirm the diagnosis and show bone growth.

Femur Stress Fracture
The femur bone is the long thigh bone. Prolonged overuse can cause a stress fracture known as a femoral stress fracture. Symptoms include:
- Pain which develops gradually as a dull ache.
- Pain is made worse when a bending force is applied to the femur.

Rectus femoris tendon inflammation/tendinopathy
This causes gradual onset pain at the front of the hip where the Rectus femoris tendon attaches to the pelvis. It may occur through overuse, or follow a tendon strain/rupture which fails to heal properly.
Other causes of anterior thigh pain which should not be missed:
The following injuries and conditions are not particularly common but it is important they are not overlooked if you have pain at the front of the thigh.
- Slipped capital femoral epiphysis occurs when there is a fracture at the neck or top of the thigh bone. The injury happens to the epiphysis which is where the bone grows as children grow older. It is more common in boys aged 11 to 16 years old and occurs gradually over a period of time.
- Perthes’ disease affects children, most commonly aged between four and eight, but can also occasionally occur in younger children and teenagers. Tiredness and groin pain are two common symptoms, and they may have a noticeable limp. Medical help is needed to diagnose this condition as early as possible to try to prevent and limit any future problems.
- Compartment syndrome – this occurs when the muscle grows too big for the sheath surrounding it and can be acute or chronic.

Sports Injury Rehabilitation App
Our step by step rehabilitation programs take you from initial injury to full fitness.
We recommend the following products to help treat Thigh injuries:
Cold Therapy Compression Wrap
Cold therapy is important for reducing pain and swelling. A reusable gel pack can be used for both hot and cold and an elastic sleeve enables easy application and compression.
Supports and protects your muscle while it is headling as well as helping to reduce pain and swelling. Retains heat later in the rehabilitation process.
A foam roller is an excellent piece of kit which can be used in place of massage to treat muscle injuries. They are also excellent when use regularly as part of your warm up.
Resistance bands are important for most sports rehabilitation and enable you to exercise any muscle from the comfort of your own home.
