Total Hip Arthroplasty (THA) is an effective treatment for severe hip
arthritis, with patients reporting high rates of satisfactory results
postoperatively. There are a variety of choices regarding THA implant
designs. Ceramic on Ceramic and Ceramic on Highly Cross-Linked
Polyethylene (XLPE) THAs are the materials of choice nowadays. The
purpose of this study is to review the effect of kinematics and kinetics
on wear (in vivo and in vitro testing) that affect wear in Ceramic on
Ceramic and Ceramic on XLPE total hip arthroplasties and identify
possible advantages amongst them. The study hypothesis was that THA
kinematics and/or kinetics, since they directly affect THA wear, could
provide data for possible advantages between the examined implant
designs. A systematic review of the literature identified no significant
evidence for biomechanical advantages between these two prostheses in
terms of wear. Further research is proposed with the use of gait
analysis systems combined with surface electromyography to further
investigate THA biomechanics at a laboratory set up. Wearable sensors
technology could also identify detailed biomechanical parameters in more
complex daily activities
