Funny stuff, "engineers seem to have made it worse! The bottom line is there is no safe hip replacement option right now"

do this 25 patients randomly received a metal on metal device (MoM) which is the type with the known metal wear issue, and 25 patients received a Titanium modular neck system which is a metal on polyethylene device with a Titanium shell (MoP), the new type intended to reduce wear particles. The results were concerning. The MoM and MoP devices caused similar increases in Titanium, Cobalt and Chromium by the end of the first year. However, the MoM device had slightly lower levels of Titanium by the end of the second year. So, the device designed to replace the original Metal on Metal hip replacement implant raised metal blood levels more than what it was supposed to replace!

The upshot? By trying to fix the problem of wear particles and increases in toxic metal ions in the blood of hip replacement patients engineers seem to have made it worse! The bottom line is there is no safe hip replacement option right now, which should concern anyone considering having this invasive surgery.
