Abstract

We read the article on "Acetabular cup migration after primary cementless total hip arthroplasty in rheumatoid arthritis and its influencing factors: a comparative study with osteoarthritic hip" by Jun-Ki Moon et al. [1] and congratulate the authors on their well-thought retrospective analysis. We had an in-depth discussion of this article in our departmental journal club and would like to present forth certain queries and concerns.
