Mechanical ejection

Patients may experience a cottony symptom called a mechanical symptom. You may feel like something is stuck in your knee and clap your hands as your knee bends back and forth.

This type of cotton is usually a sign of a torn meniscus or a weakening of the cartilage in a joint. These are tissues within the knee that soften and protect the joint. A torn meniscus or loose cartilage can hook the knee as it moves back and forth. Gives off a cotton feel.

While some meniscus tears heal on their own, those that involve deeper tissues don't have the blood vessels they need to aid the healing process. They may need a procedure called arthroscopic wound debridement to cut and repair the tear.


Crepitus is a word used to describe the crunchy sensation of bending the knee back and forth. Crepitation may be seen in patients with cartilage irritation. This happens when you have chondromalacia , which is cartilage damage or loss. It can also be seen in patients with worn cartilage, such as knee arthritis .

Unlike mechanical cotton, when there is a sensation of something hitting the knee, the sensation of crepitus is a more persistent problem .

You often feel more crackling than you hear. To check for crackles, sit on the edge of a table with your knees dangling. Then gently extend and lower your knee, resting the palm of your hand on the front of the knee. When you have crackles, you feel a crack in your hand.

Click on the tendon

There are times when the swelling of the tendons around the knee can cause them to hook into the knee when the knee is bent. The most common type is iliotibial tendonitis (IT) .

An iliotibial apparatus is a tendon that runs from the thigh to just below the knee. When this bandage becomes swollen or irritated, it can get stuck at the end of the femur when the knee is bent back and forth.

Unlike mechanical cotton, when the problem is deep within the joint, this type of cotton is felt just under the skin. You can often feel the tendon just by moving your knee while placing your hand on the affected tendon.

When to see a doctor

If you feel pain along with these symptoms, ask your doctor to examine your knee as soon as possible. This can prevent more serious knee injuries, including anterior cruciate ligament (ACL) injuries. They affect between 100,000 and 200,000 Americans each year.

Even if the knee in the knee is painless, you can still get tested. In some cases, this can be an early sign of an overuse injury. This may require losing weight, changing shoes, or doing knee strengthening exercises to protect the joint.

The best treatments directly target the specific problem that is causing the abnormal popping within the knee joint. You can alleviate crepitus and tendon problems with remedies to reduce inflammation in the knee, such as rest and anti-inflammatories.

Most mechanical problems are best treated with arthroscopic knee surgery . This is a procedure in which a camera and instruments are inserted through small incisions in the joint to repair any damage.


When you feel a popping or popping sensation in your knee, it can be due to various issues. If you have pain accompanied by popping and clicking, you should see a doctor as soon as possible. But even if you don't feel pain when clicking or popping, you can still see your doctor.

Having a doctor examine your knee can help determine if it is a serious problem or if you have nothing to worry about.
