Common Causes of Pain Behind the knee include:


When a bone is directly struck with significant force, it can cause one or more of the bones in the knee to break, causing a fracture. Fractures are a very common knee injury and are quite painful. They interfere with proper knee function and make it harder to lift the weight. Fractures require immediate medical attention.

Ligament injuries:

The most frequently occurring ligament injury is the anterior cruciate ligament (ACL) injury. It typically affects athletes as it is caused by sudden stopping and rapid changes in direction, for example when playing football. The posterior cruciate ligament and lateral collateral ligament can also get injured, although not as frequently.


This injury is very serious and requires immediate medical care. The dislocated joint can restrict blood flow to the leg and cause further harm.

However, Pain behind Knee can also be caused by chronic overuse syndrome:

  • Osteoarthritis: This is another chronic overuse condition where the cartilage of joints is worn down due to use over time and age.
  • Patellar tendinitis: People who repeatedly perform the same movement over time can develop this. The condition is common among runners and cyclists. 
  • IT (iliotibial) band syndrome: The IT band is a tissue that connects the hip to the knee, and it can become inflamed due to overexertion. This condition causes pain in the outer part of the knee.

What are the Risk Factors for Pain Behind knee?

  1. Age: The single biggest risk factor is age. 
  2. Wear and tear: Wear and tear of the knee joints can cause chronic pain. 
  3. Being overweight: By reducing one’s weight, it can decrease the added stress on the knee.
  4. Previous injury: Previous injuries such as ruptured ligaments or damaged cartilage can cause knee pain in the future.
  5. Low flexibility: A lack of regular movement and flexibility can also shift the load off the muscles and onto the knee joint while performing tasks such as walking, running, lifting something, and bending down.

Major risk factor:

Suprapatellar bursitis:

Suprapatellar bursitis is when your suprapatellar bursa becomes inflamed. As a result , it causes pain behind knee. However, The suprapatellar bursa helps to allow the quadriceps tendons to move more easily over your femur when you bend and straighten your knee.

Bursitis occurs when one of your bursa becomes inflamed or irritated. This can commonly occur at joints that receive a lot of use, such as the shoulder, elbow, and knee.

What Are the Home Remedies?

Over-the-counter pain relief drugs can be useful in the short term. In cases of an injury or a gout attack, it is helpful to remember RICE:

  • Rest.
  • Ice.
  • Compress.

Which Brace to Choose?

Knee support for meniscus injury

The meniscus is a piece of cartilage that acts as a shock absorber between your shinbone (tibia) and thighbone (femur). A torn meniscus is a common injury.

Knee support for an ACL sprain or tear

The anterior cruciate ligament (ACL) is one of the most important parts of the knee joint because of its stabilizing job. When it gets sprained or torn, usually from athletic activity, it can result in serious pain and knee instability.


Physiotherapy can help prevent it and eliminate it when squatting. However, it also tightens loose knee muscles. Also, a physiotherapist prescribes you the right exercises for knee pain. These exercises will depend on the individual weaknesses and affected structures for each patient.
