Long-term migration of monoblock vs modular design in uncemented total knee arthroplasty : a secondary report of a randomized trial using radiostereometric analysis
Background and purpose — Backside wear of the polyethylene insert in total knee arthroplasty (TKA) has been described to produce clinically significant levels of polyethylene debris, which can lead to aseptic loosening and osteolysis. Monoblock design eliminates backside wear of the polyethylene and therefore could improve long-term fixation. This randomized clinical trial (RCT) using radiostereom
