We conducted this study to review the clinical and radiographic outcomes of patients 80 years of age or older who underwent total knee arthroplasty (TKA). We identified clinical results in 60 patients (66 knees) who had a mean age of 84 years (range, 80 to 95 years) and who underwent TKA. These were compared with a non-age-matched group of 63 patients (66 knees) who had a mean age of 69 years (range, 60 to 79 years). Four patients were lost to follow-up. After a mean 43-month follow-up (range, 24 to 117 months), Knee Society pain and function scores for the study group improved from 53 points (range, 25 to 70 points) and 53 points (range, 40 to 70 points), respectively, to 94 points (range, 75 to 100 points) and 87 points (range, 45 to 100 points). There were no implant failures, 2 surgical complications, and 13 medical complications. In the matching group, there were four surgical complications (two required revision) and two medical complications. There were no radiographic failures or progressive radiolucencies. Although the incidence of medical complications in the perioperative period may be higher, TKA is a safe and effective treatment for refractory joint pain in patients over 80 years of age.
我们开展这项研究以回顾80岁及以上接受全膝关节置换术（TKA）患者的临床和影像学结果。我们确定了60例患者（66膝）的临床结果，这些患者的平均年龄为84岁（范围80至95岁），并接受了TKA。将这些结果与63例患者（66膝）的非年龄匹配组进行比较，该组患者的平均年龄为69岁（范围60至79岁）。4例患者失访。经过平均43个月的随访（范围24至117个月），研究组的膝关节协会疼痛和功能评分分别从53分（范围25至70分）和53分（范围40至70分）提高到94分（范围75至100分）和87分（范围45至100分）。没有植入物失败，2例手术并发症，13例医疗并发症。在匹配组中，有4例手术并发症（2例需要翻修）和2例医疗并发症。没有影像学失败或进行性透光线。尽管围手术期医疗并发症的发生率可能更高，但TKA对于80岁以上患者的难治性关节疼痛是一种安全有效的治疗方法。
