Articular cartilage is the smooth, gliding surface covering the bones at our joints. In osteoarthritis, the cartilage gradually wears away and contributes to inflammation, pain, bony abnormalities and activity limitations.
There are several different grades of articular cartilage damage and when performing an arthroscopic surgery, we grade the degree of cartilage wear/injury with the Outerbridge Scale; this scale ranges from 0 (no cartilage damage) to 4 (most severe cartilage damage):
There are no absolutes about who is ‘too young’ or ‘too old’ to consider reconstruction, the decision should really be made with respect to how knee instability affects a person’s ability to remain active and healthy.
