Quadriceps strain is a partial tear of the small fibers of the muscles that make up the quadriceps group. The quadriceps are the large group of muscles in the front of the thigh. They consist of four muscles in each leg that run from the hips to the knees.
A quadriceps strain can be caused by stretching the quadriceps beyond the amount of tension or stress that they can withstand.
Factors that may increase your chance of a quadriceps strain include:
Quadriceps strain may cause:
Your doctor will ask about your symptoms and medical history, your recent physical activity, and how the injury occurred. Your thighs will be examined for:
Imaging tests evaluate your leg muscles and surrounding structures. They may include:
Muscle strains are graded according to their severity:
Talk with your doctor about the best treatment plan for you. Treatment depends on the severity of the strain. Recovery time ranges depending on the grade of your injury. Treatment steps may include:
Your muscle will need time to heal. Avoid activities that place extra stress on these muscles:
Apply an ice or a cold pack to the area for 15-20 minutes, 4 times a day, for several days after the injury. Do not apply the ice directly to your skin. Wrap the ice or cold pack in a towel.
To manage pain, your doctor may recommend:
Compression can help prevent more swelling. Your doctor may recommend an elastic compression bandage around your thigh. Be careful not to wrap the bandage too tight.
Rehabilitation with a physical therapist may be required.
Use heat only when you are returning to physical activity. Heat may then be used before stretching or getting ready to play sports to help loosen the muscle.
When the acute pain is gone, start gentle stretching as recommended. Stay within pain limits. Hold each stretch for about 10 seconds and repeat six times. Stretch several times a day.
Begin strengthening exercises for your muscles as recommended.
