Knee pain at night is a common problem that can disrupt sleep and lead to daytime fatigue. It can be caused by a variety of factors, ranging from minor injuries to chronic conditions like arthritis. Understanding the potential causes and treatment options can help you find relief and improve your sleep quality.

Common Causes of Nighttime Knee Pain
Several conditions can contribute to knee pain that’s worse at night. These include:
Runner’s Knee
Runner’s knee, or patellar tendinitis, is characterized by pain behind the kneecap. This overuse injury often results from repetitive stress, muscle imbalances, or improper running form.
Osteoarthritis
Osteoarthritis is a degenerative joint disease where cartilage breaks down, causing bone-on-bone friction and inflammation. This can lead to persistent knee pain, stiffness, and swelling, often exacerbated at night. Post-traumatic arthritis, a form of OA, can develop after a knee injury.
Rheumatoid Arthritis
Rheumatoid arthritis is an autoimmune disease that attacks the joints, leading to pain, swelling, and stiffness. Nighttime pain and sleep disturbances are common in people with RA.

Meniscus Tear
A meniscus tear involves damage to the cartilage that cushions the knee joint. This can happen due to a sudden twist or injury, and the pain might not be immediately apparent but worsen at night.
Knee Bursitis
Bursitis is inflammation of the bursae, small fluid-filled sacs that cushion the joints. Knee bursitis can cause swelling, pain, and stiffness, particularly at night. It’s often caused by repetitive kneeling or direct impact.
Gout
Gout is a type of arthritis caused by uric acid buildup in the joints. This leads to sudden, intense pain, swelling, and redness, often affecting the big toe but can also occur in the knee. Nighttime gout attacks are common.
Osgood-Schlatter Disease
Osgood-Schlatter disease affects adolescents during growth spurts, causing pain and swelling below the kneecap where a tendon attaches to the shinbone. This pain is typically worse at night and in the morning.
Why is Knee Pain Worse at Night?
Several factors contribute to increased knee pain at night:
- Hormonal Changes: Cortisol, a hormone that reduces inflammation, drops at night, potentially leading to increased pain.
- Sleep Position: Maintaining one position for extended periods can put pressure on the knee joint and restrict blood flow.
- Overheating: Excessive warmth from blankets can exacerbate inflammation and pain.
- Heightened Pain Perception: Without daytime distractions, you may be more aware of knee pain at night.
- Lack of Sleep: Pain can disrupt sleep, and sleep deprivation can increase pain sensitivity.
Treatment for Nighttime Knee Pain
Treatment options vary depending on the underlying cause:
Pain Management
- Over-the-counter (OTC) pain relievers: Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and naproxen can reduce pain and inflammation.
- Prescription medications: Stronger NSAIDs or opioid pain relievers may be necessary for severe pain.
Hot and Cold Therapy
Applying heat or ice packs can help alleviate pain and swelling.
Sleep Hygiene
Improving sleep habits, such as maintaining a regular sleep schedule, creating a relaxing bedtime routine, and optimizing the sleep environment, can help manage pain and improve sleep quality.
Sleep Position Adjustments
Using pillows to support the knees and keep them aligned can reduce pressure and improve comfort.
Exercise
Regular low-impact exercise, like swimming or walking, can strengthen muscles supporting the knee and improve joint flexibility.
Physical and Alternative Therapies
Physical therapy can help improve strength, flexibility, and range of motion. Alternative therapies like acupuncture may offer some pain relief.
When to See a Doctor
Seek immediate medical attention if you experience:
- Inability to bear weight on your knee
- Severe pain lasting more than 48 hours
- Inability to fully extend or bend your knee
- Feeling of instability in the knee
- Deformity or discoloration of the knee
- Audible popping or crunching sounds with movement
Summary
Nighttime knee pain can significantly impact your sleep and quality of life. By understanding the potential causes and seeking appropriate treatment, you can find relief and improve your overall well-being. Consult with a healthcare professional to determine the underlying cause of your knee pain and develop a personalized treatment plan.
