Unicompartmental knee arthroplasty (UKA) is a treatment option for anteromedial osteoarthritis. Compared with total knee arthroplasty (TKA), UKA offers improved knee range of motion, functional recovery and decreased medical complications. Revision rates continue to be higher with UKA compared with TKA. With current UKA implants, there is no significant difference in mobile bearing or fixed bearing, or between cemented and cementless implants. Enabling technology, such as robotic-assisted surgery, has demonstrated improvements in component positioning, but no long-term difference in survival compared with traditional manual instruments.
单髁膝关节置换术（UKA）是治疗前内侧骨关节炎的一种选择。与全膝关节置换术（TKA）相比，UKA能改善膝关节活动范围、功能恢复并减少医疗并发症。与TKA相比，UKA的翻修率仍然较高。对于目前的UKA植入物，活动平台与固定平台之间、骨水泥型与非骨水泥型植入物之间没有显著差异。诸如机器人辅助手术等使能技术已证明在组件定位方面有所改进，但与传统手动器械相比，在生存率方面没有长期差异。
