Knee cracking?

When I extend my leg, my knee sometimes cracks and especially so after riding or jogging. Why? Is it a problem I can correct? Is my technique problematic?

This is a good question. It could be a problem in the future as whatever is causing the "crack" could become painful. I have cracking knees, ankles, wrists, fingers and here's my take. My big toe cracks and it started to become painful this year. I'm going to the doctor for there are other issues involved (flat feet). I used to crack my wrists until one became very painful and it stopped but after a long rest.

I guess your cracking knee could be something or it could be nothing. Only time will tell. Having surgery to removed the cartilage sounds expensive and unnecessary at this early stage.

When you *extend* it? That actually doesn't sound right. Sometimes the joint will crack when you squat or kneel down to stretch. Maybe you should check with an ortho to be sure.

It might be that your patella is not tracking straight up and down. There are various factors that can cause this.

Cycling should help that.

Running could make it worse and lead to serious damage.

You should see a sports med specialist, especially if you start to feel any pain.

squating makes it crack as well. It happens when I flex the knees. Its cracking more often after starting to cycle after a year break.

Probably your meniscus is wearing.

My right knee does the same, but only when I'm squatting and sit up. I hope there's nothing really wrong. I'll probably just ignore it until it becomes a serious problem- but I'm only 26 for crying-out-loud!

i'm the poster boy for Snap Crackle & Pop! my knees in the morning are a veritable symphony of RATATATTATATA SNAP SNAP POPOPOPOPOPOP! . I climb trees for a living (treefaller/treeclimber) and wear climbing spurs which turn your knee outwards a touch. But cycling really seems to help.

WARNING: even if BF members were doctors (most of us probably aren't) it would not be a good idea to get a diagnosis via forum posts.

Go to a doctor, have an examination and get a diagnosis.

ive had crackling knees for a long time, when i extend them under resistance. Ive heard from one doctor and a few older people i've met that it is nothing to worry about, and it never became painful. But of course, there could be many reasons behind a cracking knee, so id see a sports medicine person, there may be something you can change about your cycling or walking/lifting/general living. knee surgery sholud always be a last resort.

Sometimes my ankle will snap with every step, other times it's silent. While riding it doesn't seem to snap, though it did once, and then I just changed the angle of my foot in the clip and it stopped.

a good sports MD or Chiropractor would be $$ well spent.
