Rough knee disease
This disease is also known as "erosive arthritis" or "friction of joints" in the knee in which the cartilage in the joint dissolves due to the friction of the two bones with each other, so the cartilage is no longer able to absorb the pressure on it, and this causes pain, swelling, and a decrease in the range Movement for the knee.
