Cartilage Injury Treatments
In some cases arthroscopy can be used to 'smooth' the cartilage. Although new cartilage cannot grow to take its place, scar tissue appears.
It is also possible to transplant some cartilage from an uninjured part of the knee. Another option is to remove some normal cartilage cells, reproduce them in a lab and then later reimplant them into the damaged area so that new cartilage will grow.

If the injury is fairly recent, it is possible to put the piece back in place. More commonly, the loose body may be removed by arthroscopy.
