Jay R. Lieberman, a principal investigator with USC Stem Cell, is the new president of the American Association of Hip and Knee Surgeons (AAHKS).

He is professor and chair of the Department of Orthopaedic Surgery and director of the Institute of Orthopaedics at the Keck School of Medicine of USC and an internationally renowned total joint replacement surgeon who has a special interest in the treatment of osteonecrosis (bone death) of the hip and knee.

Lieberman assumed leadership of the organization March 25 as it prepares to mark its 25th Anniversary this November.

“I am honored to be the leader of this association during its 25th Anniversary, and I plan to continue our mission as delineated by my predecessors to enhance the profession of hip and knee surgery in order to benefit our patients,” Lieberman said.
