For decades, clinicians and researchers have debated bearing alternatives in the hip, ranging from the traditional metal-on-polyethylene (MoP) to erstwhile up-and-coming alternatives like ceramic-on-metal. The worldwide recall of a single, large-diameter metal-on-metal bearing design in 2010 [2, 3], started a sea change for the present decade in terms of what surgeons and patients were willing to accept in terms of the forgiveness of their hip implants. In the United States, at least, hip surgeons shifted their bearing preferences to polyethylene, articulating against, increasingly, ceramic heads [1]. For knee and shoulder surgeons, there was simply no contest: MoP is the dominant bearing. Polyethylene bearings, with their lower cost relative to ceramic bearings, it turns out, also fit conveniently into the current paradigm of value-based health care, both in the United States and abroad.
