Kurzfassung:
The treatments for rheumatoid arthritis (RA) have been greatly improved, and the tight control of disease activity yields superior clinical outcomes. This study aimed to elucidate the accompanying changes in hip destruction following the implementation of a treat-to-target strategy for patients with RA. Methods We extracted 190 hips over two periods, i.e. the early period (1998–2003) and the late period (2013–19), with 103 and 87 hips, respectively. The observed rheumatic changes, such as inward migration, upward migration, and femoral head collapse, were quantitatively evaluated, while osteoarthritic changes, such as the formation of a capital drop, were investigated from radiographs before primary total hip arthroplasty. Results A comparison of the two periods’ data showed that the degree of inward migration (−3.44 vs. −7.45 mm; P & lt; .001) and upward migration (+4.3 vs. +0.95 mm; P & lt; .001) significantly decreased in the late-period group. The collapse of the femoral head was not significantly different. The incidence of capital drops was significantly higher in the late-period group (7.8% vs. 27.5%; P & lt; .001). Conclusions The degree of inward and upward migration representative of rheumatic changes reduced, whereas the frequency of capital drops as osteoarthritic changes increased during the late period.
