Unicondylar knee arthroplasty (UKA) was introduced in the 1970s as a treatment option for isolated knee compartment gonarthrosis. Early results were discouraging secondary to poor patient selection, suboptimal surgical technique, and inferior prosthetic design. In recent years, there has been resurgence in the use of the UKA. Improvements in implant design, surgical technique, and patient selection have led to multiple studies demonstrating 94-98% survivorship of the implants at a 10 year follow-up. However, there still remains a paucity of evidence with regard to this treatment option for young, active patients. This case report presents the longest recorded follow-up (31 years) of a UKA in a young, active patient and it highlights that with appropriate patient selection and meticulous surgical technique, UKA may have a role as a long term treatment option in patients with isolated unicompartmental disease.
单髁膝关节置换术（UKA）于20世纪70年代被引入，作为孤立性膝关节单间室骨关节炎的一种治疗选择。早期结果令人沮丧，原因是患者选择不当、手术技术欠佳以及假体设计劣质。近年来，UKA的使用有所复兴。植入物设计、手术技术和患者选择方面的改进促使多项研究表明，在10年随访时植入物的生存率为94% - 98%。然而，对于年轻、活跃的患者而言，关于这种治疗选择的证据仍然不足。本病例报告展示了对一名年轻、活跃患者进行UKA后有记录以来最长的随访（31年），并强调通过适当的患者选择和细致的手术技术，UKA可能在患有孤立性单间室疾病的患者中作为一种长期治疗选择发挥作用。
