The Forgotten Joint Score (FJS) is a novel measurement for patients' awareness of their knee in daily life. By identifying factors that could explain pre-operative FJS levels, the clinician could better prioritize and single out patients who would benefit most from TKA. The aim of this study was to identify possible factors that may explain the variance of pre-operative FJS levels and evaluate the relationship between pre-operative FJS and pre-operative Oxford Knee Score (OKS).
Four-hundred and six individual knees undergoing primary TKA between 2014 and 2016 were included in the study. Age, gender, body mass index (BMI), pre-operative FJS and pre-operative OKS were obtained maximum 2 weeks prior to surgery. Kellgren-Lawrence (K-L) grade, alignment and joint space width (JSW) were evaluated on pre-operative radiographs.
Mean FJS was 21.1 ± 15.6. Females, younger patients and patients with high BMI had significantly the worst pre-operative FJS (p < 0.005). Females scored 6.5 FJS points lower than males. A 0.2-point increase in FJS for every added year indicated improvement in knee awareness with age. A 0.4-point decrease in FJS points for every added BMI point indicated worse knee awareness with higher BMI. There was a strong positive correlation between pre-operative FJS and pre-operative OKS according to the Spearman's rank order test (p < 0.005).
Females, younger patients and patients with high BMI had significantly the worst pre-operative joint awareness. FJS had a strong positive correlation to OKS in pre-operative patients for primary TKA. This information can be used for improved patient selection; clinically continuous low FJS despite weight loss and/or the passing of time may be indication for TKA.

遗忘关节评分（FJS）是一种评估患者日常生活中膝关节认知的新型测量方法。通过确定可能导致术前 FJS 水平变化的因素，临床医生可以更好地对患者进行分层，找出最受益于全膝关节置换术（TKA）的患者。本研究旨在确定可能导致术前 FJS 水平变化的因素，并评估术前 FJS 与术前牛津膝关节评分（OKS）之间的关系。
纳入 2014 年至 2016 年间接受初次 TKA 的 406 例膝关节。在手术前 2 周内，获得患者的年龄、性别、体重指数（BMI）、术前 FJS 和术前 OKS。术前 X 线片评估 K-L 分级、对线和关节间隙宽度（JSW）。
平均 FJS 为 21.1±15.6。女性、年龄较小的患者和 BMI 较高的患者术前 FJS 明显较差（p<0.005）。女性的 FJS 评分比男性低 6.5 分。FJS 每增加 1 岁，膝关节认知度增加 0.2 分，随着年龄的增长，膝关节认知度呈上升趋势。BMI 每增加 1 个单位，FJS 评分降低 0.4 分，表明 BMI 较高的患者膝关节认知度较差。Spearman 等级相关检验表明，术前 FJS 与术前 OKS 呈显著正相关（p<0.005）。
女性、年龄较小的患者和 BMI 较高的患者术前关节认知度明显较差。在接受初次 TKA 的患者中，FJS 与 OKS 呈显著正相关。这些信息可用于改善患者选择；尽管体重减轻和/或时间推移，FJS 持续较低可能是 TKA 的指征。
