Scientific exhibit 12, sponsored by the AAOS Committee on Biomedical Engineering and Committee on Hip and Knee Arthritis, presents state-of-the-art applications of these surfaces. It gives clinical and laboratory evidences for alternative bearing surface solutions and addresses efficacy and concerns of each bearing couple.
Recently, a class of highly cross-linked polymers has demonstrated a significant reduction in wear particle generation in laboratory simulators. They have been cleared for clinical use in the hip through the regulatory process, but to-date have no clinical experience to demonstrate their in vivo effectiveness.
A number of metal-metal articulations have received 510K clearance and are also available for clinical use.
Ceramic-ceramic couples are now anticipated to enter the American marketplace following their first FDA Advisory Panel recommendation for approval.
