摘要
目的比较年龄>60岁及≤60岁患者膝关节内侧人工单髁置换术(unicompartmental knee arthroplasty,UKA)的近期疗效,探讨年龄对疗效的影响。方法回顾性分析2016年7月—2018年6月行膝关节内侧UKA的182例患者(182膝)临床资料,其中72例患者年龄≤60岁(A组),110例>60岁(B组)。两组患者年龄比较差异有统计学意义(t=-20.198,P<0.001);性别、身体质量指数、骨关节炎侧别、Kellgren-Lawrence分级、病程以及术前西安大略和麦克马斯特大学骨关节炎指数评分(WOMAC)比较,差异均无统计学意义(P>0.05),具有可比性。记录患者术后住院时间及并发症发生情况,比较两组WOMAC评分、满意度评分以及假体翻修情况。结果A组患者术后住院时间为(4.50±1.09)d,B组为(4.46±1.29)d,组间比较差异无统计学意义(t=0.198,P=0.844)。两组切口均Ⅰ期愈合。A、B组术后早期并发症发生率分别为5.6%、3.6%,差异无统计学意义(χ^(2)=0.061,P=0.804)。两组患者均获随访,A组随访时间28~50个月,平均36个月;B组28~50个月,平均35个月。末次随访时,两组WOMAC评分均较术前改善(P<0.05),手术前后差值组间比较差异无统计学意义(P>0.05)。A、B组患者满意度评分分别为(6.6±1.7)、(6.9±1.6)分,差异无统计学意义(t=-1.326,P=0.186)。随访期间两组患者均无假体翻修。结论年龄对膝关节内侧UKA预后无明显影响,60岁以下患者也可以获得良好近期疗效。
Objective 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.Methods The clinical data of 182 patients(182 knees)who underwent medial UKA between July 2016 and June 2018were retrospectively analyzed,of which 72 patients were less than 60 years old(group A)and 110 patients were more than60 years old(group B).There was a significant difference in age between groups(t=-20.198,P<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(P>0.05).The postoperative hospital stay and complications were recorded,and the WOMAC score,satisfaction score,and prosthesis revision were compared between groups.Results 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(t=0.198,P=0.844).All incisions healed by first intention.The incidences of early postoperative complications in groups A and B were 5.6%and3.6%,respectively,and the difference was not significant(χ^(2)=0.061,P=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 followup,the WOMAC scores of both groups significantly improved when compared with those before operation(P<0.05),and there was no significant difference between groups(P>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(t=-1.326,P=0.186).There was no revision surgery in both groups during follow-up period.Conclusion 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.
