The main causes for knee arthroplasty revision later than 5 years in the study by Sharkey et al. [42] were polyethylene wear and aseptic loosening. Polyethylene wear has become a concern in total knee arthroplasty (TKA), because it has been stated as the main cause for osteolysis [1]. The presence of polyethylene particles in the joint, which are phagocytised by macrophages and giant cells [2], causes the release of many proinflammatory interleukins, which activate the osteoclasts, the main responsible cells for osteolysis [4, 22, 24].
