The U.S. Food and Drug Administration (FDA) approved Tuesday the first ceramic-on-metal total artificial hip system for osteoarthritis patients, a device made by Johnson & Johnson's DePuy Orthopaedics unit.

The move gave orthopedic surgeons and patients an additional option when considering total hip replacement surgeries, in which worn and damaged portions of bone and cartilage are removed and replaced with an artificial joint. Existing hip replacement systems use different combinations of metal, ceramic and a form of plastic called polyethylene.

The newly approved system was the first to combine a ceramic ball and a metal socket. As a condition of the approval, DePuy will conduct a post market study, monitoring patients for adverse events and metal ion concentrations in their blood, the FDA said.

In April, J&J reported its Depuy business saw US hip and knee sales decline 6 percent from a year earlier in the first quarter, though officials noted hip and knee sales also improved from the fourth quarter.
