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.
全膝关节置换术（TKA）中使用非骨水泥固定一直存在争议。上一代假体的效果不尽人意，这在一定程度上归因于设计问题。随着TKA的需求持续增加，且美国当前的人口年龄结构趋于年轻化，骨水泥固定可能因固定失败而无法提供足够的长期效果。因此，非骨水泥TKA的研发和使用再度兴起。近期的短期试验表明，现代非骨水泥TKA与骨水泥假体具有相当的生存率和功能结果。然而，需要更多前瞻性、随机试验来明确这两种固定方式之间的差异。
