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.
The Quadriceps Muscles

A quadriceps strain can be caused by stretching the quadriceps beyond the amount of tension or stress that they can withstand.
Factors that increase your risk of a quadriceps strain include: Suddenly putting stress on the quadriceps when the muscle is not ready for the stressUsing the quadriceps too much on a certain dayExperiencing a blow to the quadricepsDoing a strenuous quadriceps activity
Sports that require bursts of speed, such as:
RunningHurdlesLong jumpBasketballSoccerFootballRugbyFatigueTight quadricepsCold weatherPrevious quadriceps injury
Symptoms include: Pain and tenderness in the front of the thighStiffness and swelling in the quadricepsWeakness of the quadricepsBruising on the front of the thigh—if blood vessels are brokenPopping or snapping sensation as the muscle tears—rare
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: Tenderness and/or bruising directly over the quadricepsPain or weakness when contracting the quadriceps, particularly against resistance
Images may be taken to see how severe the injury is with: MRIUltrasound
Muscle strains are graded according to their severity:
Some stretching with small tears of muscle fibersComplete recovery can take 10-21 days
Partial tearing of muscle fibersRecovery can take up to 1-2 months
Complete tearing of muscle fibers, which is also known as a ruptureRecovery can take more than three monthsSurgery may be needed to repair the torn muscle fibers
Treatment depends on the severity of the strain.
Treatment usually includes: Rest—Do not do activities that cause pain, such as running, jumping, and weight lifting using the thigh muscles. If normal walking hurts, shorten your stride. Do not play sports until the pain is gone. Wait until your doctor has given you permission.Cold—Apply ice or a cold pack to the quadriceps area for 15-20 minutes 4 times a day for several days after the injury. Wrap the ice or cold pack in a towel. Do not apply the ice directly to your skin.Pain relief medications—Examples include
acetaminophen. Topical pain medications such as creams and patches applied to the skin are another option. Ask your doctor if you have any questions about using these medications. If you still have tenderness in the quadriceps while taking these drugs, do not return to physical activity. Check with your doctor before returning to play.
Do not give aspirin to children and teens with a current or recent viral infection because of the risk for Reye's syndrome.
elastic compression bandage
around your thigh to prevent additional swelling. Be careful not to wrap the bandage too tightly.
Elevation—Keep your leg higher than your heart as much as possible for the first 24 hours to minimize swelling.Heat—Use heat only when you are returning to physical activity. Then use it before stretching or getting ready to play sports.Stretching—When the pain is gone, start gentle stretching exercises as recommended by a healthcare professional. Stay within pain limits. Hold each stretch for about 10 seconds and repeat six times.

If you are diagnosed with a strained quadriceps, follow your doctor's
To reduce the chance that you will strain your quadriceps: Keep your quadriceps muscles strong so they can absorb the energy of sudden physical stress.
After a short warm-up period,
out your quadriceps.
Learn the proper technique for
and sporting activities. This will decrease stress on all your muscles, including your quadriceps.
