To conclude the failure factors of unicompartmental knee arthroplasty (UKA), and summarize the research progress of revision surgery.
The literature on UKA at home and abroad in recent years was reviewed to summarize its risk factors, treatment methods, including the evaluation of bone loss, prosthesis selection, and surgical techniques.
The factors inducing UKA failure mainly include improper indications, technical errors, and others. The application of digital orthopedic technology can reduce failures caused by surgical technical errors and shorten the learning curve. There are a variety of options for revision surgery after UKA failure, including polyethylene liner replacement, revision with UKA or total knee arthroplasty, with adequate preoperative evaluation prior to implementation. The biggest challenge in revision surgery is the management and reconstruction of bone defects.
There is a risk of failure in UKA, which needs to be treated with caution and should be determined according to the type of failure.
总结单髁膝关节置换术（UKA）的失败因素，并综述翻修手术的研究进展。
回顾近年来国内外关于UKA的文献，总结其危险因素、治疗方法，包括骨丢失评估、假体选择及手术技术。
导致UKA失败的因素主要包括适应证选择不当、技术失误等。数字骨科技术的应用可减少手术技术失误导致的失败，并缩短学习曲线。UKA失败后的翻修手术有多种选择，包括聚乙烯衬垫置换、采用UKA或全膝关节置换进行翻修，实施前需进行充分的术前评估。翻修手术最大的挑战是骨缺损的处理与重建。
UKA存在失败风险，需谨慎对待，应根据失败类型确定治疗方案。
