Knee clicking can be created by nitrogen bubbles bursting in your synovial fluid when applying force to your joint. The scientific term for this is cavitation, and it’s as harmless as cracking your knuckles. This next cause is generally harmless, but it may become a problem if you don’t pay attention.
When you suffer discomfort or swelling, it’s a sign that something is wrong, and you should seek medical treatment.
When you bend or straighten your knees, walk or move up or down the stairs, you may hear pops, snaps, and crackles.
REASON FOR KNEE CLICKING
Arthritis
Arthritis can cause cracking, clicking, and popping. This disorder causes the joint padding to break down due to bone and cartilage degradation, making it difficult for the knee to glide and operate properly. This might result in a lot of noise.
All portions of your lower body must be exercised to maintain your knees robust. Here’s how to maintain your knees strong, so they don’t make clicking noises.
Loose cartilage
Runner's knee
Running is beneficial to your health, but it must be done in moderation. Runner’s knee is a condition caused by putting too much strain on the tibia. The kneecap is out of alignment and does not track along the femur in this situation.
The tibia and lower bones are in charge of safeguarding your kneecap, but if they are missing, the knee will create clicking noises as you move it.
PREVENTION OF KNEE CLICKING
Calf release

How:
To perform this exercise:
- Take a seat on the floor.
- Place a tennis ball beneath one of your calf muscles.
- Place your second leg on top of the first.
- On the tennis ball, roll your calf up and down. Wiggle your foot up and down for approximately half a minute if you encounter a tight place.
This exercise helps with calf muscle stretching. These muscles can put a strain on your knee and perhaps pull the kneecap out of alignment if they are tight.
Hip flexor release

How:
- Place a 5-inch massage ball right below your hip bone while lying down on your stomach.
- Lean towards the ball with a comfortable amount of weight.
- Bend the knee on the releasing side to a 90-degree angle and swing your leg from side to side as far as you can.
- Repeat in 30-second to 2-minute intervals as needed.
IT band release
How:
- Place a foam roller beneath your lower leg, midway between your hip and knee, on the side you wish to release.
- Slide your leg up and down over the foam roller, from the top of your knee to the bottom of your hip. As much as you can, try to work over the most delicate regions.
- Repeat for 2 minutes at 30-second intervals.
Bike Ride
How:
- Another low-impact approach to strengthen your quadriceps is to ride your bike.
- Stationary bikes or normal cycles work as well, but if you haven’t been exercising, don’t enrol in an advanced cycling class. Begin slowly and steadily.
- Make it one of your three to five weekly workout sessions to incorporate this into your regimen.
- Set your timer for 30 to 45 minutes.
