Other specified injury of the quadriceps muscle or tendon can be caused by a direct blow to the quadriceps, or by repetitive strain or excessive stretching of the muscle or tendon.
Diagnosis of this condition is made through a physical examination, review of medical history, and imaging tests such as MRI or ultrasound.
Other differential diagnoses to consider include hamstring strain, patellar tendonitis, and quadriceps bursitis.
Treatment of this condition typically involves rest, ice, compression, and elevation to reduce pain and swelling. Physical therapy can also be used to strengthen and stretch the quadriceps muscle and tendon. In more severe cases, surgery may be necessary to repair the tendon or muscle.
The prognosis for this condition is generally good, especially when treated promptly and appropriately. With proper treatment, most patients will make a full recovery and be able to return to their normal activities.
