Aetiology
: Strain or sprain of the quadriceps muscle or tendon is caused by a sudden, forceful stretch or tear of the muscle or tendon. This can happen with activities such as sprinting, jumping, climbing stairs or any activity that involves a sudden increase in speed or intensity. It can also be caused by a direct blow to the front of the thigh or if the foot is planted firmly on the ground and the knee is forced to bend suddenly.
Diagnosis
: Diagnosis of a strain or sprain of the quadriceps muscle or tendon is typically done through physical examination. Your doctor may ask about the severity and location of your pain, the activities that preceded it and whether the pain has been present for a long time. Your doctor will also assess your range of motion and may perform a series of tests to determine the severity of the injury.
Differential diagnosis
of a strain or sprain of the quadriceps muscle or tendon includes other causes of thigh pain such as a muscle pull or tear, a fracture, tendonitis, or bursitis.
Treatment
: Treatment for a strain or sprain of the quadriceps muscle or tendon typically includes rest, ice, compression and elevation (RICE) to reduce swelling and pain. Your doctor may also recommend nonsteroidal anti-inflammatory medications to help reduce pain and inflammation. Your doctor may also suggest physical therapy to help strengthen and stretch the muscle, as well as to help improve range of motion.
Prognosis
: The prognosis for a strain or sprain of the quadriceps muscle or tendon is generally good with proper treatment and rest. Most people can return to activity within a few weeks. However, a severe injury may require more time for complete recovery.
