My knees tend to lock when bent for a very long time. Today it happened and Itnever went back into place correctly. I cannot straighten my leg or apply pleasure what's so ever. I feel as if my shin bone is faceing inward towards my other knee and needs to be pushed back. I have no money for doctor or hospital want to know any possible solution. Very desperate

You're going to need a doctor. Find a low cost medical center and ask them for payment arrangements.

You will need medication treatment, I am sorry you do not have medical insurance? If you are in the US I would wonder why, since it is mandatory now.

But the actual problem has to be found, and then properly treated

Get to an emergency room or clinic whether you have money or insurance or not. You need immediate treatment even if it's the local witch doctor.

There is no reason for no insurance. With no money it's called Medicaid. If you are 65+ you have Medicare. If you are employed and do not have insurance, you will be penalized on your taxes. Go to an ER, your health is too important.
