TKA is one of the most commonly performed procedures in the elderly, yet whether age influences postoperative pain, function, and complication rates is not fully understood for this group. This is because the current literature has limited followup, small sample sizes, and no comparator group.
QUESTIONS/PURPOSES: We therefore asked if increasing age adversely affects postoperative pain, Knee Society Scores(©), and complication rates.
We retrospectively reviewed all 438 patients 80 years or older who underwent primary TKA between 1995 and 2005. We established a comparator group of 2754 patients younger than 80 years. We assessed pain, the Knee Society Score(©) (KSS), and the Knee Society Function Score(©) (KSFS). The number and type of complications were recorded and those graded 2 or more using the classification of Dindo et al. were analyzed. Minimum followup was 5 years (mean, 6 years; range, 5-15.5 years).
We found no difference in pain scores at 3, 5, and 10 years between the two groups. The KSS was comparable between groups at Year 5, but the KSFS was lower in the octogenarians. Major complications rates were higher in the octogenarian group (19% versus 15%).
When compared with younger patients, octogenarians can expect comparable pain relief and KSS but lower function and more complications.
全膝关节置换术（TKA）是老年人最常进行的手术之一，但对于这一人群，年龄是否会影响术后疼痛、功能和并发症发生率尚不完全清楚。这是因为目前的文献随访时间有限、样本量小，且没有对照组。
问题/目的：因此，我们想知道年龄增长是否会对术后疼痛、膝关节协会评分（Knee Society Score，KSS）和并发症发生率产生不利影响。
我们回顾性分析了 1995 年至 2005 年间接受初次 TKA 的 438 名 80 岁及以上的患者。我们建立了一个 2754 名年龄小于 80 岁的对照组。我们评估了疼痛、膝关节协会评分（Knee Society Score，KSS）和膝关节协会功能评分（Knee Society Function Score，KSFS）。记录了并发症的数量和类型，并对使用 Dindo 等人的分类系统分级为 2 级或以上的并发症进行了分析。最小随访时间为 5 年（平均 6 年；范围 5-15.5 年）。
我们发现两组患者在术后 3、5 和 10 年的疼痛评分没有差异。两组患者在第 5 年的 KSS 相当，但 80 岁以上患者的 KSFS 较低。80 岁以上患者的主要并发症发生率较高（19%比 15%）。
与年轻患者相比，80 岁以上患者可预期疼痛缓解和 KSS 相当，但功能较低，并发症更多。
