Editorial: Synovial pathobiology and pathogenesis of inflammatory arthritis, volume II

The development of predictive tools for the prognosis of inflammatory arthritis is currently a key area of research in rheumatology. In our previous Research Topic (1), we explored current ongoing endeavors seeking to find these tools and future strategies that may be adopted to make these much-needed predictions. In the second volume of Synovial pathobiology and pathogenesis of inflammatory arthritis, we now delve deeper into the underlying rheumatoid arthritis (RA) and psoriatic arthritis (PsA) synovial tissue, explore the role of inflammation in post-traumatic osteoarthritis (PTOA), investigate synovial myeloid cell subsets and their role in remission of RA, and finally, explore the link between
disease activity indices with disease progression.
