目的 探讨年龄对关节置换手术治疗老年患者膝关节退行性骨关节炎的效果影响。方法 选取2019年6月—2022年8月期间接受关节置换手术治疗的68例老年膝关节退行性骨关节炎患者作为研究对象,将≤70岁的35例患者作为观察组,>70岁的33例患者作为对照组。经关节置换手术治疗后,观察两组患者的治疗恢复情况。结果 观察组患者术后6个月的关节活动度（ROM）评分和膝关节功能HSS评分高于对照组（P<0.05）;术后6个月的Barthel指数和健康调查简表（SF-36）评分高于对照组（P<0.05）;并发症发生率低于对照组（P<0.05）;康复优良率高于对照组（P<0.05）。结论 在老年膝关节退行性骨关节炎患者的临床治疗中,关节置换手术可以有效改善患者的症状,促进其膝关节功能的恢复。关节置换手术时机的选择,会在一定程度上影响手术疗效。相对于超过70岁的患者,70岁以内患者关节置换手术术后关节功能恢复更佳。

Objective To investigate the role of age in the effect of joint replacement surgery on degenerative osteoarthritis of the knee in elderly patients. Methods A total of 68 elderly patients with knee degenerative osteoarthritis who received joint replacement surgery from June 2019 to August 2022 were selected as study subjects, including 35 patients ≤ 70 years old as the observation group, and 33 patients >70 years old as the control group. After joint replacement surgery, the recovery of the two groups of patients was observed. Results The observation group's joint range of motion （ROM） score and knee joint function HSS score were higher than the control group's at 6 months after surgery （P<0.05）. The Barthel index and 36-item Short-Form （SF-36） score of the observation group patients at 6 months after surgery were higher than those of the control group （P<0.05）. The incidence of complications in the observation group was lower than that in the control group （P<0.05）. The excellent and good rehabilitation rate of the observation group patients was higher than that of the control group （P<0.05）. Conclusion In the clinical treatment of elderly patients with degenerative osteoarthritis of knee joint, joint replacement surgery can effectively alleviate the pain symptoms and promote the recovery of their knee joint function. The choice of the timing of joint replacement surgery will affect the curative effect to some extent. Patients younger than 70 years of age have better functional recovery after joint replacement surgery than patients older than 70 years of age.
