An internal analysis conducted by Johnson & Johnson in 2011 not long after it recalled a troubled hip implant estimated that the all-metal device would fail within five years in nearly 40 percent of patients who received it, newly disclosed court records show.
Johnson & Johnson never released those projections for the device, the Articular Surface Replacement, or A.S.R., which the company recalled in mid-2010. But at the same time that the medical products giant was performing that analysis, it was publicly playing down similar findings from a British implant registry about the device’s early failure rate.
