Total Hip Arthroplasty after Previous Acetabular Osteotomy: Comparison of Three Types of Acetabular Osteotomy

Tamaki, Tatsuya et al.
Hip

To compare surgical results of total hip arthroplasty (THA) following acetabular osteotomy, operative records of 13 hips following Chiari osteotomy (Chiari group), 22 hips following rotational periacetabular osteotomy (RAO; RAO group), 16 hips following shelf acetabuloplasty (Shelf group), and 2475 hips without previous osteotomy (Control group) were retrospectively reviewed. The operative time was significantly longer in the RAO group than in the Control group. Bulk bone augmentation was required more often in the Chiari and RAO groups than in the Control group. An early migration of the acetabular cup occurred in 2 hips in the RAO group. RAO made conversion to THA more complicated than did the Chiari osteotomy or the shelf acetabuloplasty.
