Knee Pain at Night: Causes, Symptoms, and When to Be Concerned
Knee Pain at Night — What It May Mean
Knee pain at night is a symptom that can disrupt sleep and affect overall quality of life. Some people notice aching, throbbing, stiffness, or sharp discomfort in the knee when lying down or attempting to rest. Nighttime knee pain may occur with or without daytime symptoms.
While occasional discomfort may be related to daily activity or positioning, recurring or worsening knee pain at night should be evaluated by an orthopedic specialist to determine the underlying cause.

Why Knee Pain Can Worsen at Night
At night, reduced movement and fewer distractions can make pain more noticeable. Inflammation, joint stiffness, and pressure changes within the knee may become more apparent when the body is at rest.
Knee pain at night may occur due to:
- Inflammation within the knee joint
- Reduced circulation during rest
- Joint stiffness after a day of activity
- Positioning that places pressure on sensitive structures
- Underlying joint degeneration
Common Causes of Knee Pain at Night
Several knee-related conditions may contribute to nighttime pain.
Arthritis
Arthritic changes in the knee joint may cause aching or throbbing pain that becomes more noticeable at night, particularly after daytime activity.
Joint Inflammation
Inflammation from overuse, injury, or degenerative conditions may cause discomfort that worsens during periods of rest.
Cartilage Wear
Cartilage damage or thinning can lead to increased joint sensitivity, making nighttime pain more noticeable.
Tendon or Soft Tissue Irritation
Irritated tendons or surrounding soft tissues may cause aching pain that persists into the evening or night.
Prior Knee Injury
Previous knee injuries may lead to residual joint irritation that causes nighttime discomfort, even long after the initial injury.
Symptoms That May Occur Alongside Nighttime Knee Pain
Knee pain at night may be accompanied by:
- Aching or throbbing sensations
- Stiffness after lying still
- Swelling or warmth around the knee
- Difficulty finding a comfortable sleeping position
- Pain that improves with gentle movement
- Interrupted sleep
These symptoms provide helpful context during evaluation.
When Knee Pain at Night Should Be Evaluated
An orthopedic evaluation is often recommended if:
- Nighttime pain occurs frequently
- Pain disrupts sleep on a regular basis
- Symptoms worsen over time
- Swelling or stiffness persists
- Pain occurs with little or no daytime activity
- Night pain is accompanied by functional limitations
Persistent nighttime pain should not be ignored.
How Knee Pain at Night Is Evaluated
Evaluation by an orthopedic specialist typically includes:
- Review of symptom timing and patterns
- Physical examination of knee movement and stability
- Assessment of swelling, alignment, and joint tenderness
- Imaging studies such as X-rays or MRI when appropriate
At Dr. Burke Orthopedics, evaluations focus on identifying contributing factors and creating a personalized treatment plan.
Treatment Options for Knee Pain at Night
Treatment depends on the underlying cause and severity of symptoms.

Injection-Based Options

Supporting Knee Comfort During Rest
General strategies that may support nighttime knee comfort include:
- Gentle stretching before bed
- Avoiding excessive knee strain late in the day
- Using supportive pillows to reduce joint pressure
- Maintaining regular physical activity
- Addressing knee pain early
