 What is Knee Pain?

Knee pain is a common condition that affects people of all ages. It can result from injury, overuse, aging, or underlying health conditions. The knee is one of the largest and most complex joints in the body, made up of bones, cartilage, ligaments, tendons, and muscles. When any of these structures are stressed, inflamed, or damaged, it can lead to knee pain.

Knee pain may be:

  • Acute (short-term), due to injury or strain

  • Chronic (long-term), due to underlying issues like arthritis or degeneration

Types of Knee Pain

Here’s a breakdown of the most common types of knee pain based on causes and location:

1. Anterior Knee Pain (Front of the Knee)

  • Patellofemoral Pain Syndrome (Runner’s Knee): Pain around or under the kneecap, especially when walking up stairs or sitting for long periods.

  • Chondromalacia Patellae: Cartilage under the kneecap softens and wears down.

  • Quadriceps Tendinitis: Inflammation of the tendon that connects the quadriceps muscle to the patella.

2. Posterior Knee Pain (Back of the Knee)

  • Baker’s Cyst: A fluid-filled swelling caused by inflammation, often associated with arthritis.

  • Hamstring Tendonitis: Inflammation in the tendons of the hamstring at the back of the knee.

  • Posterior Cruciate Ligament (PCL) Injury: Less common than ACL injuries, caused by a blow to the front of the knee while the knee is bent.

3. Medial Knee Pain (Inside of the Knee)

  • Medial Collateral Ligament (MCL) Injury: Often from a blow to the outer knee.

  • Medial Meniscus Tear: Common in athletes; a tear in the cartilage cushion inside the knee.

  • Pes Anserine Bursitis: Inflammation of the bursa on the inner side below the knee joint.

4. Lateral Knee Pain (Outside of the Knee)

  • Iliotibial Band Syndrome (ITBS): Common in runners; pain occurs when the IT band rubs against the outer knee.

  • Lateral Meniscus Tear: Affects the outer cartilage and can happen with twisting movements.

  • Lateral Collateral Ligament (LCL) Injury: Rare, but occurs due to trauma on the inside of the knee.

5. Knee Pain Due to Degenerative or Chronic Conditions

  • Osteoarthritis: Most common in older adults; results from wear-and-tear of cartilage.

  • Rheumatoid Arthritis: An autoimmune disease that causes inflammation in the knee joint.

  • Gout or Pseudogout: Uric acid crystal buildup or calcium deposits causing joint inflammation.

6. Traumatic Knee Pain

  • ACL Injury (Anterior Cruciate Ligament): A tear or sprain common in athletes, usually with a popping sound.

  • Meniscal Tear: Caused by twisting or trauma, often resulting in locking of the knee.

  • Knee Fractures or Dislocations: Typically from falls, accidents, or severe impacts.

Symptoms Associated with Knee Pain

  • Swelling or stiffness

  • Redness and warmth

  • Popping or crunching sounds

  • Inability to fully straighten or bend the knee

  • Instability or weakness
