A lot of times when I see my patients in OPD, I get a question that is most commonly asked is, my knee crackles, it makes a lot of noises, it pops, is there a problem? Well, for most of the conditions, there is nothing to be worried about. Because this sound in the knee, it comes de novo and goes de novo.

If the patient is complaining of pain when this crackling sound comes, then the patient may require some investigation as well. The click or the pop in the knee is a very common phenomenon that is experienced by a lot of patients. This is usually seen when patient tries to bend the knee, he tries to twist the knee joint or even tries to extend the joint as well. A lot of causes can be, it can be a loose body, it can be any kind of menisciped here and the most common cause is arthritis, which is a degenerative condition and increases with aging as well. So, the solution for this is to take rest and if the joint is injured or swollen, start with the icing as well. You can also start investigating and have a consultation with your doctor and start your medications. But most importantly, you have to start your physiotherapy rehabilitation of the knee joint which will help in strengthening the muscles around the knee joint and also improve the flexibility as well.
