Introduction
|
|---|
Total joint replacement has been very successful and cost-effective
in restoring function and mobility to millions of patients worldwide
since its advent more than thirty years ago. With improvements in
prophylaxis against infection, the fatigue strength of the components,
and skeletal fixation, wear and its sequelae have become the primary
limitation to joint replacement longevity1.
Initially termed "cement disease,"2 osteolysis
is believed to be a biological response not only to polymethylmethacrylate
but also to a variety of particles that may originate at several locations
around a joint replacement. These include the articulating surfaces,
modular component interfaces, fixation surfaces, and devices used
for adjuvant fixation3.
Recent research has been directed at understanding the biological
cascade of events that is initiated by particulate debris and results
in periprosthetic bone loss. Clinically, periprosthetic osteolysis
can lead to aseptic loosening of components, massive bone loss that
renders revision surgery substantially more complex, . . . [Full Text of this Article]
