A fixation device is a manufactured device, often bio-degradeable, which is used to fix tissues in place until healing occurs.
Fixation devices may be employed in ligament or tendon grafts or to hold together torn tissues, such as the meniscus.
Bioabsorbable fixation device
A common material for bio-absorbable interference screws is poly L-lactic acid (PLLA).
Non-bioabsorbable fixation device
Metal fixation devices are commonly made of titanium.
