Knee Cartilage Damage
Résumer cet article avec :
Cartilage damage can be divided into three categories: Firstly, a small section of cartilage can come away from the joint with a piece of bone attached. The second possible scenario is damage to the cartilage alone, which breaks into several fragments that come away in the joint causing pain and blocking. Finally, a fragment can come away with a piece of subchondral bone. Both bone and cartilage are lost in this case and the fragment, altered and worn, cannot be reattached.
