A thigh strain is the term often used to describe a tear in one of the quadriceps muscles at the front of the thigh. It is common in sprinting and jumping related sports.

Thigh strain symptoms
- Typically you will feel a sudden sharp pain at the front of the thigh.
- You may have some swelling depending on the type and severity of the injury.
- Thigh strains are graded 1 to 3 depending on how bad your injury is.
- A grade 1 is mild and a grade 3 involves a complete or near-complete tear of the muscle.

What is a thigh strain?
A thigh strain is a name often given to a tear of the quadriceps muscles at the front of the thigh. The quadriceps muscles consist of the vastus lateralis, vastus medialis, vastus intermedius, and the rectus femoris. A strain is a tear in the muscle and can range in severity, from a very small tear to a complete rupture.
Quadriceps muscle strains usually occur during activities such as sprinting, jumping or kicking. You are more likely to sustain an injury if you haven’t warmed up sufficiently.
Any of the quadriceps muscles can tear, but probably the most common is the rectus femoris. This is because it is the only one of the four muscles which crosses both the hip and knee joints. Therefore this makes it more susceptible to injury.
Quadriceps muscle strains usually occur at one of two locations in the muscle:
Musculotendinous junction (MTJ) strains
This is where the muscle joins/becomes a tendon, which then attaches to bone. This is most likely to occur just above the knee.
This is a tear higher up your thigh, in the belly of the thigh muscle, nearer the hip. This is commonly known as a ‘bulls-eye’ lesion.
Other injuries to the thigh muscles include:
- Injury to the rectus femoris tendon will be felt at the origin of the muscle at the hip. This can be a tenon strain (tear), or can also be an overuse/inflammation type injury.
- Injuries that occur following a direct impact on the muscle, such as being hit by a ball or other hard object, are more likely to be contusions and should be treated slightly differently.
Thigh strain treatment
For information only. We recommend seeking professional advice before beginning any rehabilitation program.
What can the athlete do?
Initial treatment for a thigh strain should be to apply the cold therapy PRICE principles of protection, rest, ice, compression, and elevation.
- Protect the injured muscle by wearing a thigh support or compression bandage.
- Rest from all sporting activities in the early stages of healing. Continuing to train on an injured muscle will prevent it from healing properly. Elevation of the injured limb should also be done in the early stages and this is best achieved by lying on a sofa with the leg resting upon 2 pillows.
- Ice – apply ice or better still a cold therapy and compression wrap for the first 72 hours after injury. Apply ice for 10 minutes every hour initially reducing the frequency as symptoms improve. This will help stop internal bleeding and swelling and hopefully limit the extent of the injury. After the initial acute stage treatment will depend on the severity of the injury.
- Compression will help reduce swelling and protect the area.
- Elevate the injured leg to help swelling and tissue fluids flow away from the site of the muscles strain.
What can a professional therapist do?
- A professional therapist can make an accurate diagnosis.
- They will advise you on treatment and a full rehabilitation program.
- They may also use electrotherapy such as ultrasound to aid the healing process.
- Use sports massage, especially after the acute stage has passed.
Sports massage may be beneficial after the initial acute stage has passed. Massage helps to increase blood flow to the muscles, which aids the healing process. Massage helps improve your flexibility and loosens any tight knots or lumps following injury. It is also thought to realign scar tissue and improve tissue elasticity.
Thigh strain exercises
After the initial acute stage of the injury has passed, a gradual rehabilitation program consisting of stretching and strengthening exercises should begin.
- Go direct to Thigh strain rehabilitation program
Stretching exercises should always be pain-free starting with gentle static stretches and progress through to more sports specific stretches performed dynamically (with movement). Do not start stretching too early as the healing of the muscle may be compromised (not before day 5 post-injury). The initial active range of motion exercises is done where the knee is bent through as full a range as possible. A simple static quadriceps stretch is done when pain allows.

The aim of strengthening exercises is to gradually increase the load that is put through a muscle. Strengthening exercises can start as early as day 5 as long as they are low-level and must be done pain-free.
If it hurts do not do it! Isometric or static exercises are advised first and then progress to dynamic exercises with resistance band and finishing with sports specific running and sprint drills.
Eventually, more sports specific or functional strengthening exercises are done involving sprinting, change of direction and plyometric or hopping type exercises.

We recommend the following products to help treat thigh strains:
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.
