Lump behind knee. Any of you ever had this?

Injury/Nutrition Knee

15 years ago 06/25/2008 12:05pm EDT

I was doing some repeats at the track, feeling a little soreness in my right hamstring which I assumed was from weights. I noticed that there is a lump behind my right knee and not behind my left. I stopped the workout because this concerned me. I don't know how long it could have been there.

I can feel it only when my leg is fully extended and when I point my toes up. It goes away when the toes are pointed down and I can't feel it when my leg isn't extended. I've read about Baker's cyst but I have never had a knee injury. Could it just be some benign cyst or muscle formation? The width is about the size of a dime. Should I go running today?

It could be a fat deposit.

Could a random fat deposit be in one leg and not the other? If I can't feel the bump when my leg isn't fully extended would that mean that it wouldn't be a cyst?

Interesting I guess. Maybe I'll workout based on how it feels.

Sounds just like a baker's cyst. You can have it on just one side and it'll present as kind of a hamstring type/back of the knee pain. They're benign.

It's not a tumor

It's probably not a tumor, but don't ASSUME this.

A former elite runner I know had what sounds like a very similar lump behind the knee, and the first medical advice she got was that it was probably nothing. But it was in fact a tumor. Easily removed, but nothing to mess around with.

I see. Perhaps I'll ask somebody to check it out to make sure I'm not just imagining things. And then maybe I'll make an appointment to see a doctor. Are Baker's cysts always caused by injury? That's what I've been reading online but I've never had a knee injury. Maybe I'll try icing. I'm 24 years old if that makes any difference. Anybody else think it could be a fat deposit? I've never really heard of healthy people having lumpy fat deposits.

We had a female middle distance runner on our hs team this year develop a similar lump in the back of the knee. The school trainer thought it might be a cyst and sent her to the ortho guy. He took x-rays and.........it was a lump of fat. Harmless, but we had a good time ribbing her about it. Of course, yours may be something else, so it would be a good idea to get it checked out. Good luck.

So that it is a possibility. Thanks.

Get checked for chondromalacia. I had the same symptoms and that's what it turned out to be in my case. Do not keep running on it until you have it checked.

re: had the same trouble

Must one have pain to have chondromalacia?

re: joe diddy

Could it just be a sprain of some sort? Maybe you did squats or leg presses with too much weight and something popped out of place. Anybody know what those two tendons behind the knee that connect the thigh to the calves are called?

Pay attention to whether it hurts or not. Might want to see a doctor.
