Polyetheretherketone (PEEK) may be advantageous as an alternative material to metal alloys in some orthopaedic applications. However, it is bioinert and does not osseointegrate1. A novel accelerated neutral atom beam technique (ANAB) has been developed to improve the bioactivity of PEEK where the surface is modified to a depth of 5 nm without affecting the integrity of the underlying PEEK structure2. The aim of this study was to investigate the growth of human Mesenchymal Stem Cells (hMSCs), adult human Osteoblasts (hOB) and skin Fibroblasts (BR3G) on PEEK and ANAB treated PEEK.Background
