Methods and treatments for osteolysis employing interleukin-1 receptor antagonist (IL-1ra). Activating production of interleukin-1 receptor antagonist includes incubating adipose tissue, adipocytes, whole blood, platelet rich plasma, and/or isolated white blood cells with polyacrylamide beads to produce a solution rich in interleukin-1 receptor antagonist. Activating the production of interleukin-1 receptor antagonist includes using an implantable device loaded with adipose tissue, adipocytes, whole blood, platelet rich plasma, and/or isolated white blood cells. Methods for treating osteolysis at the site of an artificial joint in a patient include administering and/or inserting the solution rich in interleukin-1 receptor antagonist and/or the implantable device, respectively. |
