Abstract: A system and method for conducting arthroscopic surgery. The system and related method may include: inserting a guide wire to a defect site; placing a lumen of a dowel over the guide wire to enable the dowel to travel toward the defect site; placing a guide pin over the guide wire to enable the guide pin to travel along the guide wire to be inserted into the lumen of the dowel; placing the cannula of a tamp over the guide pin to enable the tamp to travel along the guide pin toward the dowel; and impacting the tamp to apply a force to the tamp, wherein the tamp impacts the dowel to enable the dowel to advance with a predetermined fit-resistance into the defect site.

Abstract: A method for modulating enzymatic degradation of articular cartilage in a dog comprises administering to the dog an enzymatic degradation modulating effective amount of eicosapentaenoic acid (EPA), for example as a component of a food composition. By practice of the method in a dog having arthritis, mobility of the dog can be increased, weight bearing in an arthritic limb can be increased, and/or pain associated with arthritis can be reduced.
