Introduction
Quadriceps muscle strain is a tear of the quadriceps muscle, which is a large muscle located in the front of the thigh. The quadriceps muscle helps straighten the knee. Quadriceps muscle strains can range from mild to severe, depending on the number of fibers that are torn. Mild quadriceps muscle strains may only involve a few fibers of the quadriceps muscle. These types of strains typically heal within a few weeks with conservative treatment. Severe quadriceps muscle strains may involve a complete tear of the quadriceps muscle and may require surgery to repair. If the athlete thinks they have strained the quadriceps muscle, it is important to see a doctor or other healthcare provider right away.
What Are Quadriceps?
Quadriceps are constituted by a group of four muscles that are present in the front of the thigh. These muscles work together to extend the leg at the knee joint. A quadriceps muscle strain is a tear or rupture of one of these muscles. Quadriceps muscle injury is most common in athletes who participate in sports that involve jumping, running, and sudden changes in direction.
What Is Quadriceps Muscle Strain?
A quadriceps muscle strain is a tear in the quadriceps muscle, which is the large muscle group in the front of the thigh. The quadriceps muscle attaches to the kneecap (patella) and helps extend the leg. A quadriceps muscle strain can occur in any of the four muscles that constitute the quadriceps muscle group: rectus femoris, vastus lateralis, vastus intermedius, or vastus medialis.
Quadriceps muscle strains are classified according to their severity:
-
Grade 1: A mild strain involving only a few quadriceps muscle fibers. There is minimal pain and tenderness with grade 1 strains.
-
Grade 2: A moderate strain involving more quadriceps muscles, resulting in more severe pain and tenderness.
-
Grade 3: It happens when there is full dissociation or tear of one or more of the quadriceps muscles resulting in severe pain and tenderness.
What Are the Causes of Quadriceps Muscle Strain?
Several different causes can contribute to causing quadriceps muscle strain:
-
Overuse Injury: This is the most common cause of quadriceps muscle strain. When athletes overuse their quadriceps muscles, they can become fatigued and feel tight. This can eventually lead to a strain.
-
Improper Warm-up: If the athlete does not warm up properly before exercise, the muscles will be cold and more susceptible to injury.
-
Poor Form: If athletes use poor form when exercising, they put unnecessary stress on the muscles, leading to strain.
-
Inadequate Stretching: If the athlete does not stretch properly after exercise, the muscles will be tight and more likely to sustain a strain.
How Is Quadriceps Muscle Strain Diagnosed?
Quadriceps muscle strain is diagnosed using the following methods:
-
Physical Examination: A quadriceps muscle strain is diagnosed by a physical examination and medical history. The doctor may ask the patient to describe the symptoms and when they began. He or she will also test the knee for range of motion and tenderness. Grading of the injury and guidance for additional diagnostic tests and therapy will be determined by evaluating discomfort, any palpable defect, and strength at the time of muscle injury.
-
Imaging Tests: When the initial examination and diagnosis are unclear, or further information regarding the type and location of the muscle strain is required, imaging might be a helpful adjuvant. Imaging tests, such as magnetic resonance imaging (MRI), can show whether the patient has a muscle strain. The doctor may also order blood tests to rule out any further reasons for the symptoms, like rheumatoid arthritis.
How Is Quadriceps Muscle Strain Treated?
If the quadriceps muscle strain is grade I or II, treatment will usually involve RICE (Rest, Ice, Compression, and Elevation) and pain medication. Physical therapy may also be recommended to help stretch and strengthen the muscles. For grade III strains, surgery may be necessary to repair the torn muscle. Treatment for a quadriceps muscle strain typically involves:
-
Rice (Rest, Ice, Compression, and Elevation): It targets reducing inflammation and is regarded as a first-aid measure rather than a cure. It is believed that applying cold or ice will reduce the intramuscular temperature and the blood flow to the wounded location. Although it has not been demonstrated in the scientific literature, this might enable a quicker recovery and return to sports.
-
Drugs: NSAIDs (non-steroidal anti-inflammatory medicines) can help with pain management and facilitate an earlier return to activities. A new study only suggests a brief three to seven-day course of NSAIDs after muscular injuries because the long-term consequences of these medications in this condition are unknown. Contrarily, data showing delayed healing and decreased biomechanical strength of injured muscles strongly discourage the use of corticosteroids.
Can Physical Therapy be Employed for Quadriceps Muscle Strain?
Physical therapy for quadriceps injury involves the following:
-
Acute Therapy: A time of initial resting is used to stop the injury from worsening, and a more serious strain injury can necessitate the use of crutches at first. Here, practices like limb elevation, intermittent ice, and compression therapy are employed, which enhance interstitial fluid accumulation to reduce blood flow and interstitial fluid buildup.
-
Knee Positioning: It is critical to act quickly when a quadriceps muscle injury happens during a match or training session. One must promptly flex the knee of the injured leg at 120 degrees in the first 10 minutes after the accident. This lowers the risk of bleeding, myositis ossificans (formation of the bone inside the muscle) development, and possible muscle spasms. In practice, this can be achieved by flexing the patient's knees at 120 degrees using an elastic compression wrap or securing them in a hinged knee brace. The quadriceps will begin to mend in a shortened position if the knee is extended, making the healing process slower and more painful.
Conclusion
In the case of a quadriceps muscle strain, it is important to seek professional medical help to diagnose and treat the injury properly. In the meantime, there are some things that can be done at home to help relieve pain and improve healing, such as icing the area and taking over-the-counter pain medication. Once the quadriceps has healed, be sure to engage in regular stretching and strengthening exercises to help prevent future injuries.
