UKA is an appropriate bone-sparing solution for focal advanced knee osteoarthritis in young patients. As the expectations of patients younger than 60 years of age are different from those in an older population, we aimed to evaluate quality of life and the quality of sports activity after UKA in this population.
Sixty-five UKAs in 62 patients younger than 60 (mean age: 54.7 years; mean BMI: 28 kg/m(2)) performed between 1989 and 2006 were included. At last follow-up (minimum 2 years), before the objective evaluation, patients were asked to fill in a KOOS questionnaire and a specific sports questionnaire including the UCLA score and questions from the Mohtadi score.
With a mean follow-up of 11.2±5 years (range, 2-19 years), the KOOS score was higher than 75 points in 90% of the patients for the quality-of-life categories but also for the score's four other categories: 83.4% of the patients had resumed their sports activities and the mean UCLA score was 6.8 (range, 4-9); 90% of the patients reported no or slight limitation during sports activities. The function KSS improved from 52±4 to 95±3 points postoperatively and the Knee KSS from 50±4 to 94±4 points. With three patients undergoing revision for an isolated insert exchange, one for septic loosening and three for osteoarthritis in the external compartment, the 12-year Kaplan-Meier survivorship was 94%.
These results confirmed that UKA can provide good patient-rated outcomes, which is very important in this demanding population. As for TKA, wear remains a problem in this active population.

UKA 是治疗年轻患者局限性晚期膝关节骨关节炎的一种适当的保骨治疗方法。由于 60 岁以下患者的期望与老年患者不同，我们旨在评估该人群 UKA 后的生活质量和运动活动质量。
共纳入 1989 年至 2006 年间 62 例年龄小于 60 岁（平均年龄：54.7 岁；平均 BMI：28kg/m²）的 65 例 UKA 患者。在最后一次随访（至少 2 年）时，在进行客观评估之前，患者需填写 KOOS 问卷和专门的运动问卷，包括 UCLA 评分和 Mohtadi 评分中的问题。
平均随访 11.2±5 年（范围，2-19 年），90%的患者在生活质量评分的所有 5 个类别中，KOOS 评分均高于 75 分，而在其他 4 个类别中，83.4%的患者恢复了运动活动，平均 UCLA 评分为 6.8（范围，4-9）；90%的患者在运动时报告无或轻微受限。术后功能 KSS 从 52±4 分改善至 95±3 分，膝关节 KSS 从 50±4 分改善至 94±4 分。3 例患者因单独的植入物置换、1 例因感染性松动和 3 例因外侧间室骨关节炎而翻修，12 年 Kaplan-Meier 生存率为 94%。
这些结果证实 UKA 可以提供良好的患者评分结果，这在这一高要求的人群中非常重要。与 TKA 一样，在这一活跃人群中，磨损仍然是一个问题。
