This is a prospective cohort study assessing the survival of a new acetabula component which is based on the original Trident acetabular system (cementless shell) which is used for Total Hip Arthroplasty. The manufacturer recently introduced the evolution of this product, the Trident® II acetabular shell which was launched in 2017. This implant is CE marked and is now widely available for the UK market, however has minimal clinical outcomes data to support its use. As part of a stepwise introduction of devices to orthopaedic practice. This study will report the 10 year implant survival and patient functional outcomes of this new implant.
