Knee pops on walking, jumping, gets locked frequently, no pain. Should I be concerned?

My right knee pops every time a jump and almost every step I take walking upstairs but it does not hurt when it pops. It also locks up quite a bit while I am sitting down or driving with my legs just slightly bent. I don t usually have any pain but it will ache sometimes when it s cold outside or I did some sort of jumping exercise or running up hill. I am a 20 year old female and played sports in high school but as far as I know I have never injured my knee, although I did sprain that same ankle pretty bad a few years ago. My parents and brothers are trying to get me to go to a doctor thinking it s the meniscus but since I do not have pain in my knee very often I don t know if I should really be concerned.

Thanks for posting your query.

As you describe the symptoms as painless loud crunching noise, I do not think we have any reasons to worry.

Sometimes as a normal phenomena, fluid (synovial fluid) that lubricate the joint release bubbles which pop and crackle with movement. This occurs very commonly after a period of inactivity or during certain movements. I am not sure if this is what you have, but this is my most likely explanation to your symptoms.

You don't need to worry if there is no associated joint pain; but you have to do some conditioning exercises to improve the overall integrity of the joint - stronger muscle will take the weight of the joint and help to reduce the pressure on articulating surfaces, thus preventing any damage to the joint.

Wishing you good health...
