Important advancements have come over the past 15 years in our knowledge of the fabrication of total knee implants, resulting in optimistic projections of the long-term results from total knee arthroplasty. At present, one of the principal reasons for failure of total knee arthroplasty (TKA) is wear the ultra-high molecular weight polyethylene (PE) insert. Attempts to alleviate this problem have focused on highly on improved biomaterials such as highly cross-linked PE, ceramic materials, and alternative metals such as tantalum. The authors review recent developments in the field of biomaterials as applied to total TKA.
