Learn about common causes of pain behind the knee, why discomfort can develop in this area, and how physiotherapy may help you understand your symptoms. Discover why the right exercises depend on what's causing your knee pain and how an individualized treatment plan can support your movement and rehabilitation goals.
Suffering From Pain Behind the Knee? Here's What You Should Know
Pain behind the knee can make everyday activities such as walking, bending your leg, climbing stairs, and exercising uncomfortable. It may develop gradually, appear after physical activity, or begin following an injury.
The back of the knee, also called the posterior knee, contains several structures, including muscles, tendons, ligaments, and parts of the knee joint. Because these structures work together to support movement, discomfort in this area can have several possible causes.
If you're experiencing pain behind your knee, it's important to understand what may be contributing to it before deciding which exercises or treatments to try.
What Causes Pain Behind the Knee?
Pain at the back of the knee isn't a condition on its own. It's a symptom that can be associated with different musculoskeletal issues and other medical conditions.
Some possible causes include:
1. Hamstring or Calf Muscle Strain
The hamstrings run along the back of your thigh, while the calf muscles extend down your lower leg. Strain or irritation involving these muscles may cause discomfort around the back of the knee, particularly after running, jumping, or other physical activities.
2. Baker's Cyst
A Baker's cyst is a fluid-filled swelling that develops behind the knee. It may cause tightness, pressure, or discomfort, especially when bending or straightening the leg. It can also occur alongside an underlying knee joint condition.
3. Meniscus or Ligament Injury
The meniscus helps cushion the knee joint, while the ligaments provide stability. Injuries involving these structures may cause pain, swelling, stiffness, or difficulty moving the knee. Depending on the injury, discomfort may also be felt at the back of the joint.
4. Tendon Irritation or Other Knee Conditions
Tendon problems, arthritis, and other conditions affecting the knee may also contribute to pain behind the knee. The location of the discomfort alone cannot confirm the underlying cause.
Because these conditions can have overlapping symptoms, an appropriate assessment can help determine whether further examination or treatment is needed.
Can Exercise Help With Pain Behind the Knee?
Exercise may be part of a rehabilitation plan for certain causes of knee pain. Depending on your symptoms and assessment findings, appropriate exercises may help improve strength, mobility, flexibility, and movement control.
However, not every type of pain behind the knee responds to the same exercises.
For example, someone experiencing muscle weakness may need a different approach from someone with a recent muscle strain, a Baker's cyst, or a knee joint injury. Starting with the wrong exercise or pushing through pain may aggravate some conditions.
That's why it's helpful to understand what's contributing to your symptoms before beginning a targeted exercise routine.
Why See a Physiotherapist for Pain Behind the Knee?
A physiotherapist can assess your symptoms, movement, strength, and functional limitations to help determine an appropriate approach to care.
Depending on the findings, your physiotherapist may recommend:
Your physiotherapist can also help you understand which movements may be appropriate for your condition and when you may need further medical evaluation.
If pain behind your knee persists, worsens, or affects your ability to walk, exercise, or carry out daily activities, consider getting it assessed rather than relying on a general exercise routine.
When Should You Seek Medical Attention?
Although some causes of knee discomfort can be managed with appropriate rehabilitation, certain symptoms need prompt medical attention.
Seek urgent medical assessment if you experience severe pain, significant swelling, difficulty bearing weight, or a hot and red knee accompanied by fever.
Sudden pain or swelling in the calf, particularly with warmth or redness, also needs urgent evaluation because it can sometimes indicate a blood clot. If you experience chest pain or shortness of breath alongside leg symptoms, seek emergency care.
Don't assume that pain behind the knee is simply muscle tightness, especially when symptoms appear suddenly or are accompanied by swelling.
