Abstract
There is ongoing debate over the use of cementless fixation in total knee arthroplasty
(TKA). Previous generation prostheses resulted in less than optimal outcomes which
was somewhat attributed to design issues. As the demand for TKA is continuously increasing
and the current U.S. age population is getting younger, cemented fixation may not
provide adequate long-term outcomes due to failure of fixation. Thus, there has been
a reemergence of the development and use of cementless TKA. Recent short-term trials
have demonstrated that modern cementless TKA has comparable survivorship and functional
outcomes as cemented prostheses. However, more prospective, randomized trials are
needed to clearly delineate any differences between these two fixation options.
