With recent improvements in metal-on-metal bearing designs, surface replacement arthroplasty (SRA) has gained popularity, as it provides a substantial preservation of the proximal femoral anatomy. However, due to the minimal resection of the femoral head which reduces the access to the acetabulum remarkably, the procedure is technically demanding and wider surgical exposure is necessary. Consequently, blood requirements may be increased, but only a few direct comparisons of the two procedures have been published and with conflicting results2. (...)
