The round femoral stem provides a similar clinical outcome but more serious proximal stress shielding compared to the rectangular stem in cementless total hip arthroplasty without a shortening osteotomy in patients with Crowe type 2 or 3 hip dysplasia

Abstract

Objectives: This study aims to compare clinical and radiological follow-up results of a rectangular (SL-Plus (R)) or a round (Synergy (R)) femoral component in patients with Crowe type 2 or 3 hip dysplasia operated with total hip arthroplasty (THA) without a shortening osteotomy.
