Many possibilities. : This could be a number of issues depending on what other symptoms you have. I would want to know if the knee is swollen, red or warm? How long have you had it? And is it all the time, or does it come and go? ...Read more

Hard to say: Hard to say based upon your note. Was the MRI normal or abnormal? If it was abnoal, it should give a good idea of what the problem is. If it was normal, other sources of pain in that area such as neurological or vascular conditions should be sought. ...Read more

You most likely have: A meniscal tear and all your symptoms, that you describe, are typical for such a problem. The knee buckling under you is a dangerous situation, as it makes you fall and can result in broken bones or other injuries. You need to see an orthopod to get evaluated/investigated and most likely will require a scope surgery to be treated. ...Read more

See a doctor: If your knee is not swollen, the inability to straighten it completely or bend it means that something is physically blocking the joint. However, squatting involves bending so i wonder what you mean by "can't bend". There are a few possibilities but you will need to see a doctor. ...Read more
