Sudden impact
Articular cartilage damage can occur as a result of a sudden, direct blow to the cartilage. For example, your cartilage can be damaged if you have a bad fall directly onto your knees, or following a bad tackle while playing football or rugby.
This is why cartilage damage often occurs in people who play physical contact sports.

Gradual damage
Cartilage can also be damaged gradually over time through ‘wear and tear’. Your risk of developing this type of cartilage damage is increased if you are overweight or have a problem with the structure of your joint. This type of long-term damage to the cartilage is known as osteoarthritis.
