Anterior Knee Pain

What is an Anterior Knee Pain?

Anterior knee pain, also known as patellofemoral pain syndrome, is a common condition characterized by pain and discomfort in the front of the knee. It primarily affects the area where the kneecap (patella) rests on the thigh bone (femur). This condition is often seen in physically active individuals, such as athletes or people who engage in activities that involve repetitive knee movements.

The front and center of the knee, typically beneath the patella, can occasionally hurt in an adolescent or young adult who is physically active and engages in sports. Adolescent anterior knee discomfort is a condition that frequently affects young, healthy athletes, especially girls.

Adolescent anterior knee pain is typically brought on by overuse or a training regimen that does not include enough stretching or strengthening exercises, not by a physical defect (abnormality) in the knee. The majority of the time, straightforward treatments like rest, over-the-counter drugs, and strengthening exercises will ease anterior knee pain and enable the young athlete to resume their preferred sports.


The largest and most powerful joint in your body is the knee. It is made up of the patella (kneecap), the upper end of the tibia, and the lower end of the femur (thighbone). Articular cartilage, a smooth, slick substance that covers the ends of the three bones that make up the knee joint, protects and cushions the bones as you bend and straighten your knee.

Ligaments join one bone to another bone. In your knee joint, there are 4 main ligaments. They function as sturdy cords to hold the bones together and maintain the stability of your knee.

Tendons join the muscles to the bones. The front thigh muscles are joined to the kneecap by the quadriceps tendon. The patellar tendon runs from the kneecap to your shinbone.

Causes of Anterior Knee Pain

It’s usually difficult to pinpoint the precise cause of anterior knee pain. Because of its intricate architecture, which enables it to flex while bearing enormous loads, the knee joint is extremely sensitive to:

  • Small problems with alignment
  • Activity
  • Training
  • Overuse

For instance, anterior knee discomfort may result from weakening in the quadriceps muscles near the front of the leg. The quadriceps muscles assist in keeping the kneecap in a groove at the end of the femur when the knee bends and straightens. Having weak quadriceps can result in the kneecap not tracking properly in the groove. This may result in tendonitis or chondromalacia patella, an irritation of the cartilage lining on the bottom of the kneecap caused by additional tension on the tendons.

Adolescent anterior knee discomfort may also result from the following other factors:

  • Imbalance in the quadriceps and hamstrings, the thigh muscles that support the knee joint
  • Hamstring and quadriceps muscles that are tight
  • The legs’ hips and ankles not being in proper alignment
  • Using ineffective methods or tools for sports training
  • Footwear or playing surface modifications
  • Excessive exercise or a change in the style of training
  • A new sport is being started too soon, or increasing physical activity too quickly.

Symptoms of Anterior Knee Pain

The most typical sign of anterior knee discomfort is a dull, aching pain that gradually develops and is frequently triggered by activities. Other typical signs include:

knee popping or cracking as you ascend stairs or stand up and move after a lengthy period of sitting

Pain at night

Knee pain when performing repetitive knee-bending motions (such as jumping, squatting, running, and other weightlifting exercises)

Pain brought on by a modification in activity or intensity, the playing field, or equipment

The edema around the knee is typically absent in adolescents with anterior knee pain syndrome. It’s also rare to experience symptoms like clicking, locking, snapping, or the knee giving way. These signs should prompt a visit to the doctor since they point to a mechanical issue with the knee.


Physical Examination

Your physician will:

To identify the source of pain behind your kneecap and rule out other issues, examine your knee. perhaps have you walk, run, jump, squat, sit, and lay down

Your doctor will also look at these things while performing the physical exam:

  • Position of the kneecap and the lower leg’s alignment
  • Knee stability, hip rotation, and the hips’ and knees’ range of motion
  • Check the kneecap for any discomfort
  • The connection between the kneecap and the thigh muscles
  • Strength, range of motion, hardness, tone, and circumference of the quadriceps and hamstrings in the front and back of the thighs, respectively
  • The flexibility of the feet and how tightly the heel cord is wound


X-rays. Simple X-rays can produce precise images of dense things like bone. Your doctor will be able to detect any issues with the kneecap’s position or shape using special X-ray imaging. Your doctor might order X-rays of both of your legs to check for any differences.

MRI scans, or magnetic resonance imaging. The soft tissues (including ligaments, tendons, and muscles) around your knee can be visualized better with an MRI scan than they can with an X-ray.

During the first diagnosis and workup of anterior knee discomfort, an MRI is typically not performed unless you have symptoms like locking or catching of the knee.

To determine if there is an internal issue within the knee joint, such as damage to the cartilage or ligaments, your doctor may request an MRI during a subsequent visit if your symptoms do not go away on their own or get better with treatment.

Treatment of Anterior Knee Pain

You can make some easy adjustments to ease anterior knee pain.

Medical Treatment

Nonsteroidal Anti-inflammatory Drugs (NSAIDs)

Physical Therapy Exercises for Anterior Knee Pain

Gentle stretching and strengthening exercises may help ease the pain while enhancing your flexibility and range of motion if your knee pain is brought on by an injury, surgery, or arthritis.

Even though it may seem counterintuitive to exercise an injured or arthritic knee, doing so is better for your knee than sitting still. Your knee may stiffen if you don’t move it, making the pain worse.

You can strengthen the muscles that support your knee joint by gently stretching and strengthening exercises. Stronger muscles can ease the strain and impact on your knee and make it easier for your knee joint to move.

A doctor might advise imaging if your knee pain is severe to assess the damage.

Consult with a doctor or physical therapist to make sure the exercises are safe for you before beginning a program for knee pain. Depending on your circumstances, they might advise making some changes or starting an exercise regimen under the guidance of a physical therapist.
