To compare the short-term effectiveness of medial unicompartmental knee arthroplasty (UKA) between patients younger or older than 60 years of age, and to investigate the impact of age on the effectiveness.
The clinical data of 182 patients (182 knees) who underwent medial UKA between July 2016 and June 2018 were retrospectively analyzed, of which 72 patients were less than 60 years old (group A) and 110 patients were more than 60 years old (group B). There was a significant difference in age between groups (=-20.198, <0.001). No significant difference was found in gender, body mass index, surgical sides, Kellgren-Lawrence grading, disease duration, and preoperative Western Ontario and McMaster University Osteoarthritis Index (WOMAC) score between groups (>0.05). The postoperative hospital stay and complications were recorded, and the WOMAC score, satisfaction score, and prosthesis revision were compared between groups.
The length of postoperative hospital stay was (4.50±1.09) days in group A, and (4.46±1.29) days in group B, with no significant difference between groups (=0.198, =0.844). All incisions healed by first intention. The incidences of early postoperative complications in groups A and B were 5.6% and 3.6%, respectively, and the difference was not significant (=0.061, =0.804). All patients were followed up. The follow-up time were 28-50 months (mean, 36 months) in group A and 28-50 months (mean, 35 months) in group B. At last follow-up, the WOMAC scores of both groups significantly improved when compared with those before operation (<0.05), and there was no significant difference between groups (>0.05) in the difference before and after operation. The satisfaction scores were 6.6±1.7 in group A and 6.9±1.6 in group B, with no significant difference between groups (=-1.326, =0.186). There was no revision surgery in both groups during follow-up period.
Age has no significant effect on the prognosis of medial UKA, and patients younger than 60 years of age can also obtain good short-term effectiveness.
比较年龄小于或大于60岁患者行内侧单髁膝关节置换术（UKA）的短期疗效，并探讨年龄对疗效的影响。
回顾性分析2016年7月至2018年6月期间行内侧UKA的182例患者（182膝）的临床资料，其中72例患者年龄小于60岁（A组），110例患者年龄大于60岁（B组）。两组间年龄差异有统计学意义（=-20.198，<0.001）。两组间性别、体重指数、手术侧别、Kellgren-Lawrence分级、病程及术前西安大略和麦克马斯特大学骨关节炎指数（WOMAC）评分差异均无统计学意义（>0.05）。记录术后住院时间及并发症情况，并比较两组间WOMAC评分、满意度评分及假体翻修情况。
A组术后住院时间为（4.50±1.09）天，B组为（4.46±1.29）天，两组间差异无统计学意义（=0.198，=0.844）。所有切口均一期愈合。A组和B组术后早期并发症发生率分别为5.6%和3.6%，差异无统计学意义（=0.061，=0.804）。所有患者均获随访。A组随访时间为28 - 50个月（平均36个月），B组为28 - 50个月（平均35个月）。末次随访时，两组WOMAC评分较术前均显著改善（<0.05），两组手术前后评分差值比较差异无统计学意义（>0.05）。A组满意度评分为6.6±1.7，B组为6.9±1.6，两组间差异无统计学意义（=-1.326，=0.186）。随访期间两组均无翻修手术。
年龄对内侧UKA预后无显著影响，年龄小于60岁的患者也可获得良好的短期疗效。
