Taking a step, you hear a “crack!” Taking the other step, you hear a “pop!” These sounds come from both knees. What do these sounds mean? Are we starting to have knee osteoarthritis? This might be a question many people are unsure about and ask themselves. Today, we will clarify the doubts about these sounds coming from the knees.
Causes of the “Crack! Pop!” Sound in the Knee
The sounds from the knee when moving or stepping can actually come from several causes.
- Movement of bones and tendons: When the knee joint moves, the cartilage and tendons around the knee may move and cause sounds.
- Friction of cartilage: In some cases, the cartilage in the knee may rub against each other, which can cause sounds.
- Gas in the joint: Our joints contain lubricating fluid with gas. When the joint moves, this gas may break apart and cause sounds.
Which “Crack-Pop” Sounds Are Dangerous?
As mentioned above, the crack-pop sounds come from our own body producing those sounds, including the movement of bones and tendons, friction of cartilage, and the gas in the joint breaking apart. The sound alone is not dangerous, but if the sound occurs along with pain, it may be harmful.
How to Take Care of Yourself When You Have “Crack-Pop” Sounds in the Knee
If the crack-pop sounds occur along with other symptoms such as pain, swelling, inflammation, or unstable walking, you may need additional self-care as follows:
- Rest and avoid heavy use: If you feel pain or inflammation in the knee, avoid heavy use such as standing or walking for long periods to prevent excessive stress on the knee.
- Cold compress: If there is swelling and inflammation, applying an ice pack wrapped in a cloth to the knee area can help reduce symptoms.
- Stretching and light exercise: Stretching the muscles around the knee and doing light exercises such as walking or cycling can help strengthen muscles and reduce friction in the knee joint.
- Eating a healthy diet: Foods rich in nutrients that help build bones and joints, such as calcium and vitamin D, help keep the knees strong.
- Using a knee brace: If there is pain or instability, using a knee brace can help provide stability and reduce friction in the knee joint.
- Weight loss: If you are overweight, losing weight helps reduce pressure on the knees and lowers the risk of crack-pop sounds.
When Should You See a Doctor?
If you have any of the following symptoms, you should see a doctor for further examination and treatment:
- Severe or chronic knee pain
- Swelling and inflammation that does not subside
- The knee feels unstable or cannot move normally
- Frequent and increasingly severe “crack-pop” sounds
