Fixation and clinical outcome of uncemented peri-apatite-coated versus cemented total knee arthroplasty : Five-year follow-up of a randomised controlled trial , using radiostereometric analysis (RSA)
Aims The optimal method of tibial component fixation remains uncertain in total knee arthroplasty (TKA). Hydroxyapatite coatings have been applied to improve bone ingrowth in uncemented designs, but may only coat the directly accessible surface. As peri-apatite (PA) is solution deposited, this may increase the coverage of the implant surface and thereby fixation. We assessed the tibial component f
