In suitable patients, unicompartmental knee arthroplasty (UKA) offers a number of advantages compared with total knee arthroplasty. However, the procedure is technically demanding, with a small tolerance for error. Assistive technology has the potential to improve the accuracy of implant positioning.This review paper describes the concept of detailed UKA planning in 3D, and the 3D printing technology that enables a plan to be delivered intraoperatively using patient-specific instrumentation (PSI).The varying guide designs that enable accurate registration are discussed and described. The system accuracy is reported.Future studies need to ascertain whether accuracy for low-volume surgeons can be delivered in the operating theatre using PSI, and reflected in improved patient reported outcome measures, and lower revision rates.

对于合适的患者，单髁膝关节置换术（UKA）与全膝关节置换术相比具有诸多优势。然而，该手术技术要求高，容错率小。辅助技术有提高植入物定位准确性的潜力。本文综述描述了3D详细UKA规划的概念，以及能够使用患者特异性器械（PSI）在术中实施规划的3D打印技术。文中讨论并描述了能实现精确配准的各种导向设计。报告了系统准确性。未来研究需要确定低手术量的外科医生能否在手术室使用PSI实现准确性，并体现在患者报告结局指标的改善以及翻修率的降低上。引用本文：2018；3 DOI: 10.1302/2058 - 5241.3.180001 。
