Twenty-Year Clinical, Functional, and Radiographic Outcomes of Hip Resurfacing Arthroplasty: A Retrospective Cohort Study

Background

Hip resurfacing arthroplasty (HRA) was developed as a bone-preserving alternative to conventional total hip arthroplasty (THA), particularly for young and physically active patients. However, concerns regarding metal-on-metal bearings have substantially restricted its use. This study evaluated the long-term clinical, functional, radiographic, and implant survivorship outcomes of HRA.
