Unicompartmental knee arthroplasty (UKA) has increased in popularity in the last years, also in younger and more active patients with great expectancies. The purpose of our study was to investigate the change in sports activities before and after medial UKA. We surveyed 53 athletic patients; all underwent cemented medial UKA, to determine not only their subjective and objective evaluation of clinical status with Hospital for Special Surgery (HSS) and visual analog score (VAS) score, but also their sporting and recreational activities at a mean follow-up of 48 ± 6 months (range, 18-56 months). At the last follow-up, 48 of 53 patients were engaged in sports and recreational disciplines, resulting in a return to activity rate of 90%. No early failure and no cases of revision were reported. The frequency of activities (sessions per week) and the time session remained constant at the time of survey. The most common activities after surgery were hiking, cycling, and swimming. Several high-impact activities, as well as skiing and football, had a significant decrease in participating patients. There were no gender-, age- and body mass index (BMI)-related differences. UKA can be considered a viable alternative in relatively young patients with high functional requirements and the correct indications, however, warning the patients about the risks of polyethylene wear and early loosening of the prosthetic components as a result of the resumption of sporting activities in high impact. LEVEL OF EVIDENCE: Prospective case series, level 4.
单髁膝关节置换术（UKA）在过去几年中越来越受欢迎，在年轻且活动量较大、期望值较高的患者中也是如此。我们研究的目的是调查内侧UKA术前和术后体育活动的变化。我们对53名运动患者进行了调查；所有患者均接受了骨水泥固定的内侧UKA，以确定他们使用特殊外科医院（HSS）和视觉模拟评分（VAS）对临床状况的主观和客观评估，以及在平均随访48±6个月（范围18 - 56个月）时的体育和娱乐活动情况。在最后一次随访时，53名患者中有48名参与了体育和娱乐活动，活动恢复率为90%。未报告早期失败病例和翻修病例。在调查时，活动频率（每周次数）和每次活动时间保持不变。术后最常见的活动是徒步、骑自行车和游泳。一些高冲击力的活动，如滑雪和足球，参与的患者显著减少。不存在与性别、年龄和体重指数（BMI）相关的差异。对于功能需求高且适应症正确的相对年轻患者，UKA可被视为一种可行的替代方案，然而，要警告患者由于恢复高冲击力体育活动导致聚乙烯磨损和假体部件早期松动的风险。证据水平：前瞻性病例系列，4级。
