BACKGROUND/PURPOSE: Forgotten Joint Score (FJS) is designed to asses patient recovery post Total Knee Arthroplasty (TKA) in a new dimension. It assess the ability to forget the operated joint as artificial during activities of daily living. New Knee Society Score (NKSS) is developed to encompass objective and subjective outcome as well as an assessment of patient expectation and satisfaction. Our purpose was (1) to determine FJS at 1 year post TKA in Indian Patients, and (2) to assess convergent validity between FJS and the NKSS. We hypothesised that FJS should strongly correlate with the Satisfaction (SS) and Knee perception(KPS) sub-component of NKSS.
METHODS
We enrolled 181 patients who underwent primary TKA during an 8-month duration. They were prospectively followed up at 1-year review clinic when FJS and NKSS were administered. 169 patients completed the assessment forms and 13 patients were lost to follow-up. Statistical evaluation was done with Spearman correlation test.
RESULTS
Mean FJS at 1 year was 66.6 ± 25.9 with 14% ceiling and 1% floor effects. There was a mild to moderate correlation of FJS with NKSS ( < 0.001, = 0.47) and its sub-scores ( < 0.001; = 0.43 and = 0.44). There was a weak correlation of FJS with NKSS sub-components of SS and KPS ( < 0.001; = 0.37 and 0.25, respectively).
CONCLUSION
Mean FJS at 1 year post TKA showed convergent validity with NKSS; however, the correlation was not strong enough to use them interchangeably. Hypothesis that FJS should strongly correlate with the NKSS sub-components of satisfaction and joint perception was refuted. We conclude, FJS provides unique evaluation in recovery post TKA, different from NKSS.
LEVEL OF EVIDENCE
Level III.
背景/目的：遗忘关节评分（FJS）旨在从一个新的维度评估全膝关节置换术（TKA）后患者的恢复情况。它评估患者在日常生活活动中将手术关节视为非人工关节的能力。新膝关节协会评分（NKSS）的制定涵盖了客观和主观结果以及对患者期望和满意度的评估。我们的目的是：（1）确定印度患者TKA术后1年时的FJS；（2）评估FJS与NKSS之间的收敛效度。我们假设FJS应与NKSS的满意度（SS）和膝关节感知（KPS）子成分密切相关。
方法
我们纳入了181例在8个月期间接受初次TKA的患者。在1年复查门诊对他们进行前瞻性随访，此时进行FJS和NKSS评估。169例患者完成了评估表，13例患者失访。采用Spearman相关检验进行统计学评估。
结果
1年时的平均FJS为66.6±25.9，天花板效应为14%，地板效应为1%。FJS与NKSS（<0.001，=0.47）及其子评分（<0.001；=0.43和=0.44）存在轻度至中度相关性。FJS与NKSS的SS和KPS子成分之间存在弱相关性（<0.001；分别为=0.37和0.25）。
结论
TKA术后1年时的平均FJS与NKSS显示出收敛效度；然而，相关性不够强，不能互换使用。FJS应与NKSS的满意度和关节感知子成分密切相关的假设被推翻。我们得出结论，FJS在TKA术后恢复情况方面提供了与NKSS不同的独特评估。
