Optimizing cementing technique

Supported by the long-term clinical success and survivorship analysis, cemented total knee arthroplasty continues to be the gold standard against which alternative means of fixation need to be compared. Fundamental to implant longevity is meticulous technique, bone preparation, and handling of the cement. Fixation of polymethylmethacrylate to the cancellous bony surface is achieved by the irregular configuration of the bony surface and the penetration of the cement into the bone. Well-fixed cemented components have shown very little micromotion at the fixation interface, with little displacement over the years. A well-designed and properly positioned cemented total knee arthroplasty has a greater than 90% chance of surviving more than 15 years.
