A thigh bruise is a bruise to the group of large muscles in the front of the thigh. They are called the quadriceps muscles. A thigh strain is a stretch or tear of a muscle or tendon in the quadriceps area. Tendons are strong bands of tissue that attach muscle to bone. This type of injury is often called a pulled muscle. A thigh bruise is caused by a direct hit to the muscles of the thigh. A strain may be caused by overuse or by a sudden movement of the thigh in activities like sprinting or jumping.
