Can't fully extend leg. Any Thoughts?
« on: November 25, 2005, 04:06:52 AM »

Hi, I'm new to this board.

There are times when I can't fully extend my leg.  I would be able to bend my knee fully, but not be able to extend it all the way.   
It would be very painful to even try to extend it to a lock position. But no problems or pain bending my knee.

It has happened before.  Happens usually when I'm do some form of sports.
It happens maybe several times a year.   Not a constant problem, but the durations are getting longer. 
Few years ago when this would happen, I would have to sit down on the ground reach my toes and my knee would wiggle back to normal.

When it happened last summer, I was unable to extend my knee for a couple of weeks before it got back to normal itself.
Just a week ago it happened again playing soccer and I wasn't able to fully extend my knee for a week.

And just today, I was sitting on my couch with my problem leg under me (not knowingly) and that did it for me.
I thought I was going to be out for another week, until I tried bending my knee all the way back and brought it over to the outside.  Then bending my knee all the way back and brought it over to my inside and when trying to extend all the way, (feeling something moving in my knee)
It seemed like it went back into place.

What is causing this to happen?
Damaged meniscus?
Piece of cartilage from my torn meniscus(if it's torn at all from a previous injury??) got flipped and was making my knee unable to extend?

I tried looking for info on this and I that's all I could come up with.

Anything I can do to prevent this from happening again?
Will I need to go under the knife?


Your experience and knowledge is much appreciated.

no pain really..

When this problem happens,
the only pain I get is when I try to fully extend my leg.
I can bend my knee with no problems.

Hi,

I think you should see a knee specialist sooner rather than later. It sounds as though you rknee is getting worse but you shouldn't leave it until it's completely unbearable before you decide to do something about it.
I've never had this problem with my knee, so it would be difficult to advise you.
Does your knee swell up at all? Do you get pain? Is it worse after sports? Is it worse at night? Do you know what is moving around inside your knee?
These are all questions you probably already have the answers to. A knee specialist will be able to clinically examine your knee and diagnose fairly quicly what is wrong. You may also consider asking for x-rays, MRi and ultrasound scans if no conclusive asnwers are given to you.
Sorry I couldn't be of more help.

A friend of mine had what sounds to be exactly the same thing as you have.  The problem would come and go, and then one day it locked up in an almost 90 degree bent position.  Turns out it was a piece of cartiage wandering around the knee joint.  They took it out and he's been basically fine ever since.  If I remember correctly, the recovery time was nil.  Hope your problem is as easy to fix as his was.

Thanks for your replies!

It only swells up when it happens.  The only pain I get is when it happens, and i try to straighten my leg.  During anything I do, including sports, there is no pain if the reverse lock up does not happen.

I'm assuming it's a piece or a flap of cartilage moving around in my knee. It does make sense.
Good to hear that your friends problem was easy to fix.

I'm perfectly fine now.  No pain or nothing, but I haven't been as active as I have been.  Just being cautious right now.

Do you guys think I should carry on my activities and sports?
Is there anything I can do to prevent this?  Putting on a knee brace or knee compressor when playing sports and running around?
