Outcome analysis of various bearing surface materials used in total hip replacement

Abstract

Since the first total hip replacement (THR) in 1938 by Philip Wiles, prosthesis materials and THR surgical technologies have developed rapidly. In this review, we use internationally-published research to synthesize a comprehensive analysis of the specific characteristics and clinical outcomes of different bearing surfaces used in THR. Polyethylene, metallic alloys, and ceramic have become the three most commonly used hip prosthesis bearing surfaces after decades of hip implant development. Different bearing surface types have varying characteristics that offer specific benefits and risks of complication. A thorough understanding of the unique properties and possible complications of each type of bearing surface is critical to surgeons tasked with selecting appropriate implant materials for total hip replacement.
