Many people experience clicking, popping, or cracking sounds in their knees, especially during movements like squatting, climbing stairs, or standing up. This can feel alarming, but in most cases, a clicky knee is not a sign of serious damage.
The technical term for these noises is crepitus, and it often comes from harmless causes. Small bubbles of gas can be produced in the knee, on movement, and they can pop producing a sound. This is normal and completely benign and can occur in any synovial joint. Other times, tendons or ligaments may momentarily rub over the bone as the knee bends, creating a click. If there’s no pain, swelling, or instability, these sounds are usually considered normal.
However, if the clicking is accompanied by discomfort, locking, giving way, or swelling, it may suggest an underlying issue such as cartilage wear, meniscus injury, or patellofemoral (kneecap) tracking problems. Over time, repetitive strain, past injuries, or weakness in supporting muscles can also contribute.
When Should You Seek Help?
- If the clicking is new, persistent, or worsening
- If there is associated pain, stiffness, or swelling
- If the knee feels unstable, locks, or limits your activity
A physiotherapist can assess your movement patterns, muscle strength, and joint mechanics to identify whether the clicking is harmless or linked to a condition needing management.
Treatment often focuses on strengthening the quadriceps, hips, and glutes to better support the knee, improving flexibility, and correcting movement technique.
In short, a clicky knee without pain is usually nothing to worry about. But if it’s painful or interfering with your daily activities, it’s worth getting assessed. With the right guidance, most knee issues can be managed effectively without surgery.
