Rupture of the rectus femoris tendon

What is the rectus femoris muscle?

The rectus femoris muscle is one of quadriceps muscles. It goes from the hip to the knee and can be used to straighten the knee or lift the knee up. This muscle can rupture or become inflamed at the upper part. The main cause of this is overuse through kicking or explosive movements as in sprint starts.

Symptoms include:

• A sudden sharp pain at the front of the hip / in the groin usually whilst doing some explosive activity.
• Swelling and bruising may occur.
• Pain in lifting the knee up against resistance.
• Pain when pressing in at the point of injury.
• If it is a total rupture then it will be impossible to contract the muscle.

What can the athlete do about it?

• Rest and apply cold therapy and compression immediately.
• Use crutches if needed.
• See a sports injury professional.
• It is important to properly rehabilitation this injury to avoid re-injury at a later date.

What can a sports injury specialist or doctor do?

• Use ultrasound or laser treatment.
• Use sports massage techniques after the acute phase (very important).
• Operate if the muscle has torn completely.
• Prescribe a full rehabilitation programme.

A partial rupture of muscle can lead to inflammation after the initial rupture has healed. You can avoid groin injuries by ensuring the muscles are strong and flexible through strengthening and stretching exercises.
