Medial unicompartmental knee arthroplasty (UKA) is considered the most effective treatment for anteromedial knee osteoarthritis. Cementless fixation of UKA was developed to reduce aseptic loosening. We performed a review of the recent literature to assess the latest outcomes of cementless UKA.
A review of English literature was performed on Medline through Pubmed. Retrospective or prospective studies with at least 2 years of follow-up (FU) and at least 20 patients were included. The PRISMA 2009 flowchart and checklist were considered to edit the review. Survival rate, revision rate, time for revision, incidence of radiolucent lines and reasons for revision (such as aseptic loosening, osteoarthritis progression, bearing dislocation or periprosthetic fracture) were extrapolated from the papers.
Nineteen articles were included in the review, only 2 with a level of evidence of I. A total of 3432 UKA with a FU range of 24-132 months were analyzed. The studies showed good clinical and functional outcomes. In 12 studies, survival rate were more than 90%. Revision rate for aseptic loosening were lower than 2% for 15 studies.
Cementless UKA represents a surgical option allowing low revision rate. Further high-quality long-term studies would better clarify complications, clinical and radiological results of this promising fixation method.
内侧单髁膝关节置换术（UKA）被认为是治疗前内侧膝关节骨关节炎最有效的方法。非骨水泥固定 UKA 的发展旨在减少无菌性松动。我们对最新文献进行了回顾，以评估非骨水泥 UKA 的最新结果。
通过 Pubmed 在 Medline 上进行了英文文献的回顾。纳入了至少 2 年随访（FU）和至少 20 例患者的回顾性或前瞻性研究。采用 PRISMA 2009 流程图和检查表对综述进行编辑。从论文中推断出生存率、翻修率、翻修时间、透亮线发生率和翻修原因（如无菌性松动、骨关节炎进展、轴承脱位或假体周围骨折）。
综述共纳入 19 篇文章，其中仅 2 篇为证据水平 I。共分析了 3432 例 UKA，随访时间为 24-132 个月。这些研究显示出良好的临床和功能结果。在 12 项研究中，生存率超过 90%。15 项研究中无菌性松动的翻修率低于 2%。
非骨水泥 UKA 是一种允许低翻修率的手术选择。进一步的高质量长期研究将更好地阐明这种有前途的固定方法的并发症、临床和影像学结果。
