Contusions
A contusion, which many people simply call a bruise, often develops from an impact to the thigh, which compresses the muscles against the hard surface of this part of the leg. As a result, this trauma may cause bruising and inflammation. It is a common injury in many impact sports and can lead to pain and a reduced range of movement.
Strains
Also known as a pulled quad, this is another common and painful sports injury, particularly among athletes who perform sudden, forceful leg movements. It occurs when a person overstretches a muscle or tendon, especially as a result of fatigue, overuse, or improper use.
Tendinopathy
Tendinopathy refers to tendon injuries that often result in pain, swelling, and impaired function that typically occur from overuse. Tendons are thick tissues that attach bone to muscle. In the case of the quads, they attach these muscles to the patella. Two of the main types of tendinopathy are tendinitis and tendinosis.
Tears
A quadricep tear describes when a tendon becomes either partially or completely severed. It is a similar injury to a strain but involves overstretching and tearing. In some cases, the injury may begin as a partial tear where the tendon is fraying, but then progresses, causing the tendon to tear completely.

Function
All four quadriceps are powerful extensors of the knee joint. They are crucial in walking, running, jumping and squatting. Because the rectus femoris attaches to the ilium, it is also a flexor of the hip. This action is also crucial to walking or running, as it swings the leg forward into the ensuing step. The quadriceps, specifically the vastus medialis, play the important role of stabilizing the patella and the knee joint during gait.
Clinical significance
The quadriceps femoris muscle is a target for manual therapy and physical therapy from repetitive strain injuries, such as from skiing.
The quadriceps femoris muscle is the most common site of myositis ossificans.
Society and culture
In strength training, the quadriceps are trained by several leg exercises including the squat, leg press, and leg extension.
Etymology
