Exploring the Symphony of Joint Clicks

Have you ever noticed your knees, shoulders, or neck popping or cracking when you move? Joint noises are extremely common and, in many cases, completely normal. At Matter Rehabilitation Physical Therapy, we often get asked: “Should I be worried when my joints pop?”

Let’s break down what causes joint popping, when it’s harmless, and when it may be a sign that physical therapy can help.

What Causes Joints to Pop or Crack?

Your joints are complex structures designed for movement and stability. Each joint is made up of:

• Tendons – connective tissue that links muscles to bones and allows movement

• Ligaments – tissue that connects bone to bone and provides joint stability

• Cartilage – smooth, protective tissue that cushions joints and reduces friction

  
  

When these structures move together, sounds can sometimes occur—this is a normal part of joint mechanics. These joint noises are referred to as crepitus, a medical term used to describe popping, cracking, clicking, or grinding sensations.

Normal Reasons Your Joints Make Noise

In most cases, joint popping is not harmful and does not indicate injury. Common, non-painful causes include:

• Gas Bubbles in the Joint: Your joints contain synovial fluid, which helps lubricate movement. Changes in pressure can cause gas bubbles to form and collapse, creating the familiar “pop”—similar to cracking your knuckles.

• Tendons or Ligaments Moving: As you move, tendons or ligaments may slide over bone or other structures. This movement can cause clicking or snapping sounds, especially in the knees, hips, and shoulders.

If these sounds are painless, they are usually not a cause for concern.

When Joint Popping May Signal a Problem

Joint noises accompanied by pain, swelling, stiffness, or instability may indicate an underlying condition. Some conditions commonly associated with painful joint popping include:

• Osteoarthritis or joint degeneration

• Tendinitis

• Bursitis

• Autoimmune conditions such as lupus

  
  

If your joints pop and it hurts—or if the sounds are getting worse over time—it’s important to seek professional evaluation.

When Should You See a Physical Therapist?

You should consider scheduling a physical therapy evaluation if you experience:

• Painful joint popping or clicking

• Swelling or stiffness in a joint

• Limited range of motion

• Difficulty performing daily activities or exercise

  
  

Early intervention can prevent minor joint issues from becoming long-term problems.
