Grinding sensation, "buckling" and random pain in the knee?

Hello everyone, I have visited an orthopedic last week and had an X-ray on both of my knee, the doctor suspected that the cartilage has became rough and that is why I felt pain sometime as the bone rubs a rough cartilage. However, I have been quite worried about the "buckling" sensation where I personally perceive it as "something is clicking inside my knee" when I am standing in certain pose but not at all when walking, not sure if this is due to rough cartilage since doctor doesn't confirm rough cartilage causes that...

And, I have been climbing stairs sideway in my house because there will be grinding sensation in my knee if I climbs normally after 2 to 3 days, doctor told me that there is no need to climb sideways.In the end, the doctor told me to avoid running, squat and any exercises that will render a lot of pressure on my knee. So..my question is basically what is causing in the knee to feel "buckling", will rough cartilage really causes buckling? I have searched on the internet for quite a while and still can not find an exact syndrome that matched all my symptoms. I am really worried about this as I fear there might be another problem going on.

The condition is called chondromalacia patellae. This rough cartilage on the patella grinds when you bend your knee. Putting power across the patella-femoral joint to ascend stairs increases the stress across this joint and causes pain. The pain is what makes your knee buckle. Just like moving a rusty hinge takes more power than a smooth hinge, the "rough" cartilage in the joint forces the knee to use more power and may force your knee to give way.
