Stiff knee but no pain? Here are some possible causes

Stiff Knee but No Pain?

Stiffness, or difficulty moving and extending, is a common problem for joints across the body, especially as we age. Since our knees bear so much weight and are essential to movement, stiffness here is a very common issue. While occasional stiffness in the morning or after a bout of physical activity is normal and typically nothing to be concerned about, people experiencing knee stiffness on a regular basis should seek professional treatment. 

Even if your stiffness is not painful, it is still important to be proactive about seeking care. While it can be easy to discount a stiff knee with no pain as not serious, it can potentially become painful if it is allowed to progress. As you seek diagnosis and treatment for your knee stiffness, having an understanding of possible causes can be helpful. 

We’re always here to help. Don’t hesitate to reach out with any questions as you look over the following information. 

These conditions and injuries can cause a stiff knee without pain

It is common to associate stiffness and immobility with pain, but there are some cases where it develops independently. These include: 

  • Arthritis — As joint cartilage wears down, it can cause stiffness due to a lack of lubrication. For some people, this symptom begins to develop before aches and pains. 
  • Muscle tightness — The muscles around the knee can become tight with overuse, leading to stiffness. This can often be a precursor to a more painful strain. 
  • Ligament injuries — A minor ligament sprain may only result in some stiffness at first, but like other injuries, it can quickly become painful if left untreated. 


If you are dealing with knee stiffness that has not improved in a short period of time, a physical therapist can help you identify the underlying cause and provide an effective treatment plan.
