@intervoke: Knee osteoarthritis occurs when the cartilage gradually wears away, leaving it worn and rough. If this cartilage completely degenerates, the space between the bones decreases considerably and allows for bone-on-bone friction. Eventually, knee OA can cause osteocytes, loss of function, and a lack of bearing weight on the joint.#Painmanagement #sportsinjury #osteoarthritis#Kneereplacement#modanimation #mod
