Finger Joint Clicking Causes: A Comprehensive Guide

Finger joint clicking is also known as knuckle cracking. It is a common occurrence that affects many people. It is caused by the release of nitrogen gas bubbles from the synovial fluid that lubricates the joints. The sound is created when the bubbles collapse, creating a popping noise.

Causes of Finger Joint Clicking

The most common cause of finger joint clicking is knuckle cracking. Knuckle cracking is a harmless habit that does not cause any long term damage to the joints. However, it can be annoying to others and may lead to inflammation if done excessively.

Other causes include:

  • Ligament injury: A ligament injury can cause the joint to become unstable leading to clicking and popping noises.
  • Osteoarthritis: Osteoarthritis is a degenerative condition that affects the cartilage in the joints. As the cartilage breaks down, the bones rub against each other, causing pain, stiffness and clicking noises.
  • Rheumatoid arthritis: Rheumatoid arthritis is an autoimmune disease that causes inflammation in the joints. This inflammation can lead to swelling, pain and clicking noises.
  • Gout: Gout is a type of arthritis caused by the buildup of uric acid crystals in the joints. These crystals can cause inflammation, pain and clicking noises.
  • Trigger finger: Trigger finger is a condition that causes the tendons in the hand to become inflamed and swollen. This inflammation can cause the tendons to catch on the bones, leading to clicking and popping noises.

Risk Factors

The following factors may increase your risk of developing knuckle cracking:

  • Age: It is more common in older adults as the cartilage in the joints tends to break down with age.
  • Occupation: People who have jobs that require repetitive hand use are at increased risk of developing knuckle cracking.
  • Medical conditions: People with certain medical conditions, such as osteoarthritis, rheumatoid arthritis and gout are at increased risk.
  • Sex: Finger joint clicking is more common in women than in men.

Treatment for Finger Joint Clicking

In most cases, knuckle cracking does not require any treatment. However, if you are experiencing pain, swelling or stiffness in your joints you should see a doctor.

If your finger joint clicking is caused by an underlying medical condition, such as osteoarthritis or rheumatoid arthritis, your doctor may recommend treatment for that condition. This may include medication, physical therapy or surgery.

If your finger joint clicking is caused by a ligament injury your doctor may recommend splinting or physical therapy to help the ligament heal.

If you have trigger finger, your doctor may recommend splinting, corticosteroid injections or surgery to release the tendon sheath.

Preventing Finger Joint Clicking

There is no way to completely prevent this condition. However, you can reduce your risk of developing it by avoiding repetitive hand use and taking breaks when performing activities that require a lot of hand strength.

If you have this, it is important to avoid cracking your knuckles excessively. This can irritate the joints and lead to inflammation.

When to See a Doctor

You should see a doctor if you experience any of the following symptoms along with finger joint clicking:

  • Pain
  • Swelling
  • Stiffness
  • Redness
  • Warmth
  • Difficulty moving your finger
  • A popping sensation that is accompanied by pain

These symptoms may indicate an underlying medical condition, such as ligament injury, osteoarthritis, rheumatoid arthritis, or gout.


Finger joint clicking is a common occurrence that is usually harmless. However, if you are experiencing pain, swelling, or stiffness in your joints, you should see a doctor to rule out any underlying medical conditions.
