I don't know if anybody out there has this problem, I will explain.
My left knee locks up when I bend it, when I put weight on it---bending down to the floor. It doesn't do it everytime, but when it does, I cannot walk on it at all.
I went to the emergency room the 1st time it happened. They gave me a straight brace, and 2 days later the pain subsided. Now, I don't know when or if it will lock up when i bend.
Sometimes when it locks up, if I bend my knee to the left or to the right, it will unlock. But, then it becomes very sore.
I have had x-rays, and an MRI. Both showed nothing wrong. ??? This totally perplexes me, as something is wrong!!!

I will be having a Diagnostic Arthroscopy to try to determine the problem. Does anybody out there have this same problem?
I would love to hear about it, and what the problem just might be.
Thanks!
