A quadriceps muscle strain refers to an injury or tear of one of the quadriceps muscles, which are located on the front of the thigh. This injury often occurs during activities that involve sudden acceleration or deceleration, excessive stretching, or a direct impact to the quadriceps. Common symptoms include pain, swelling, tenderness, and loss of strength or mobility in the affected area. Treatment for a quadriceps muscle strain typically involves rest, ice therapy, compression, elevation, and physical therapy exercises to promote healing and restore strength and flexibility. In severe cases, surgical intervention may be considered.
