The Origins of UHMWPE in Total Hip Arthroplasty

Hip simulation is not a new science. The literature traces hip simulation back to the 1960s, with pioneers like Sir John Chamley emphasizing the importance of in vitro testing [1-3], as discussed in Chapter 4. This early work on in vitro evaluation of hip bearing materials was mainly based on trial and error, but it successfully predicted the superior wear performance of UHMWPE over PTFE that opened up the modem era of total hip arthroplasty. In Chamley s original study using a pin-on-plate wear test machine, UHMWPE outperformed PTFE by a factor of 1600 [4]. In his later clinical follow-ups, UHMWPE outperformed PTFE by a factor... [Pg.369]
