(Pulled Quadriceps)
Definition
Definition
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 4 muscles in each leg that run from the hips to the knees.

Causes
Causes
A quadriceps strain can be caused by stretching the quadriceps beyond the amount of tension or stress that they can withstand.
Risk Factors
Risk Factors
Factors that may increase your chance of a quadriceps strain include:
- Suddenly putting stress on the quadriceps when the muscle is not ready for the stress
- Using the quadriceps too much on a certain day
- Experiencing a blow to the quadriceps
- Doing a strenuous quadriceps activity
- Sports that require bursts of speed or sudden twists and turns, such as running, jumping, basketball, or football
- Fatigue
- Tight quadriceps
- Cold weather
- Previous quadriceps injury
Symptoms
Symptoms
Quadriceps strain may cause:
- Pain and tenderness in the front of the thigh
- Stiffness and swelling in the quadriceps
- Weakness of the quadriceps
- Bruising on the front of the thigh—if blood vessels are broken
- Popping or snapping sensation as the muscle tears—rare
Diagnosis
Diagnosis
You will be asked 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 quadriceps
- Pain or weakness when contracting the quadriceps, particularly against resistance
Imaging tests evaluate your leg muscles and surrounding structures. They may include:
Muscle strains are graded according to their severity:
- Grade 1—Some stretching with micro-tearing of muscle fibers
- Grade 2—Partial tearing of muscle fibers
- Grade 3—Complete tearing of muscle fibers. This may also be called a rupture or avulsion.
Treatment
Treatment
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:
Supportive Care
The leg muscles will need time to heal. RICE is often the main part of treatment:
- Rest—Activities may need to be restricted in the first few weeks. Normal activities will be gradually reintroduced as the injury heals to avoid making things worse.
- Ice—Ice therapy may help relieve swelling in the first few hours after the injury. Heat or cold may be recommended throughout recovery if they provide benefits.
- Compression—Compression bandages can provide gentle pressure to help move fluids out of the area.
- Elevation—Keep the leg elevated to help fluids drain out or to prevent fluids from building up.
Physical Therapy
A physical therapist will assess the muscles. An exercise program will be created to help recovery and to strengthen the muscles. If possible, the therapist will also look at what may have caused the injury and recommend changes.
Prevention
Prevention
To help reduce your chance of a quadriceps strain:
- Keep your quadriceps muscles strong so they can absorb the energy of sudden physical stress.
- Learn the proper technique for exercise and sporting activities. This will decrease stress on all your muscles, including your quadriceps.
- Warm up and stretch before vigorous activity.
