Thigh Muscle Strain

Thigh strain

A thigh muscle strain or quadriceps strain is a tear in one of the quadriceps muscles at the front of the thigh. It is common in sprinting and jumping-related sports. Other common muscle strains in the thigh area are Hamstring strains and Groin strains.

Thigh muscle strain symptoms

If you have suffered a strained thigh muscle then symptoms typically include:

  • 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 from 1 to 3 depending on how bad your injury is
  • A grade 1 is mild and grade 3 involves a complete or near-complete tear of the muscle

What is a thigh muscle strain?

The quadriceps muscles at the front of the thigh consist of the vastus lateralis, vastus medialis, vastus intermedius, and the rectus femoris.

thigh muscle strain anatomy

A thigh muscle strain is a tear in the muscle and ranges in severity, from a very small tear to a complete rupture. Quadriceps muscle strains usually occur during activities such as sprinting, jumping or kicking. Not warming up properly is a often a factor.

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 cross both the hip and knee joints. Therefore this makes it more susceptible to injury. Thigh 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 the bone. This is most likely to occur just above the knee.

Bulls-eye lesion

This is a tear higher up your thigh, in the belly of the thigh muscle, and 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 tendon 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.

Initial treatment for a thigh strain should be to apply the cold therapy PRICE principles of protection, rest, ice, compression, and elevation.

Protect your injured muscle by wearing a thigh support or compression bandage. Compression helps reduce swelling and protects the area.

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.


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 swelling and hopefully limit the extent of the injury. After the initial acute stage treatment will depend on the severity of the injury. Elevate the injured leg to help swelling and tissue fluids flow away from the site of the muscles strain.

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.

Sports Massage for thigh strains

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.

It helps improve 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.

Stretching exercises

Thigh muscle strain stretching exercise

Always do stretching exercises pain-free. Start with gentle static stretches where you ease into the stretch and hold. Later, progress to more sports-specific stretches performed dynamically (with movement). Do not stretch too early after a muscle strain because you are likely to inhibit healing.

thigh muscle strain strengthening exercise

Strengthening exercises

The aim of thigh 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!

perform isometric exercises first in the early stages. Later progress to dynamic resistance band exercises before progressing to 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.
