Knee osteoarthritis:
Arthritis, in general terms, means destruction of articular cartilage that usually results in dryness, pain, and decreased range of motion, and if you are careless about it, it can bring you many disabilities.
Morning dryness that goes away in less than half an hour and worsens by staying in one position is a sign of knee osteoarthritis.
With aging and improper activities, the cartilaginous joint surfaces are destroyed, and the bones of the thighs and legs collide directly, and this is the cause of your pain.
Surgical treatments are often the last choice, and they may cause you lots of problems, so before surgery, be sure to try appropriate non-surgical treatments.
