MoM total hip replacements in Europe: a NORE report

[摘要] Metal-on-metal (MoM) bearings have been used since the early years of total hip replacement (THR). Early historical MoM prostheses from the 1960s, 1970s and 1980s include the McKee Farrar hip and the Ring hip prostheses.1 They can be considered the first generation of metal-on-metal total hip replacement (MOM-THR). Their metal-on-polyethylene (MoP) counterpart was Charnley’s low friction arthroplasty.1 The Charnley MoP prosthesis had lower rates of early aseptic loosening than the first-generation MoM-THR and thus became the preferred bearing over MoM.1-4 Around the turn of the millennium, a second generation of MoM-THR, including resurfacings, was introduced with the claim of reduced wear and superior implant survival, especially in high demanding young patients due to better metal alloys and hardening methods.5-7 Initially, second-generation MoM-THR showed good outcomes in younger patients.8 However, subsequent reports were more concerning with higher revision rates and occurrence of pseudo-tumours and ARMD (Adverse Reaction to Metal Debris).
