Nowadays artificial joint substitution can be assessed as a definite part of orthopedic surgery. The good primary results must not obscure the fact that in spite of great progress in the field of endoprosthesis, numerous problems must still be considered unsolved. Most important are the problems associated with anchoring the implant into living bone tissue. New ways of cement-free anchorage are being sought. The presentation of possible alternatives and their indicative limitation to alloplastic joint substitution shows that there are possibilities which can be carried out before a possible artificial joint substitution or instead of it. Since joint substitution is still in a phase of development, further advances may be expected in the future.
如今，人工关节置换术可被视为骨外科的一个明确组成部分。良好的初期效果不应掩盖这样一个事实，即尽管在假体领域取得了巨大进展，但仍有许多问题被认为尚未解决。最重要的是与将植入物固定到活骨组织相关的问题。人们正在寻找无骨水泥固定的新方法。对所有oplastic关节置换的可能替代方案及其指示性局限性的介绍表明，在可能进行人工关节置换之前或取而代之的是，有一些可行的方法。由于关节置换仍处于发展阶段，预计未来会有进一步的进展。
需注意，原文中“alloplastic”这个词有误，推测可能是“alloplastic”，常见释义为“异质成形的” ，这里结合语境推测可能是想说“全关节置换”，比如“total alloplastic joint replacement” ，但由于原文错误，翻译可能不太准确。如果能修正原文错误信息，译文会更精准。
