What are the main findings? Response: The aim was to disentangle some of the potential reasons for the recent decline in joint replacement rates among rheumatoid arthritis (RA) patients in the developed world. The main findings from our UK patient-level analysis indicated that joint replacement rates were not significantly different for users of TNF inhibitors versus the patients who remained only on conventional synthetic DMARDS, however we did find that TNF inhibitor use amongst older RA patients was associated with a 40% reduction in hip replacement rates.

What are the main findings? Response: The main cause of failure for total hip replacements is implant loosening which is often a consequence of particle-induced peri-implant osteolysis. Unfortunately, this condition is usually not diagnosed until it has progressed to the point of needing a revision surgery. We discovered two biomarkers that may be useful for identifying at risk patients much earlier than is currently possible.
