There is no consensus on how age and expectations influence planning for total knee arthroplasty (TKA). This study developed and evaluated a new expectation questionnaire and assessed the relationship between preoperative expectations and patient characteristics.
The questionnaire evaluated expectations for mobility, pain, participation, and rate of recovery after surgery. Fifty-five participants completed a 6-minute walk test and expectation questionnaire prior to TKA; 17 participants repeated the questionnaire one week later for reliability testing. Analysis of the questionnaire included intra-class correlation coefficient (ICC), homoscedasticity, skewness, kurtosis, multicollinearity, and descriptive measures. A four-step hierarchical linear regression was completed to determine the relationship of patient age, BMI, previous contralateral TKA, and 6-minute walk test scores to expectations.
The questionnaire showed good/high test-retest reliability (ICC 0.84; 95% CI: 0.57, 0.94; > 0.001). The final model was significant in predicting expectation scores = 0.19 ( = 0.017).
This questionnaire reliably measures patient expectations before TKA; however, further research is needed. Although we anticipated younger age to be related to higher expectations, higher function prior to TKA appears to be more strongly associated with higher expectations.
关于年龄和期望如何影响全膝关节置换术（TKA）的规划，目前尚无共识。本研究开发并评估了一种新的期望调查问卷，并评估了术前期望与患者特征之间的关系。
该问卷评估了对术后活动能力、疼痛、参与度和恢复速度的期望。55名参与者在全膝关节置换术前完成了6分钟步行测试和期望调查问卷；17名参与者在一周后重复填写问卷以进行信度测试。对问卷的分析包括组内相关系数（ICC）、同方差性、偏度、峰度、多重共线性和描述性指标。完成了一个四步分层线性回归，以确定患者年龄、体重指数（BMI）、先前对侧全膝关节置换术以及6分钟步行测试分数与期望之间的关系。
该问卷显示出良好/高度的重测信度（ICC 0.84；95%置信区间：0.57，0.94；P > 0.001）。最终模型在预测期望分数方面具有显著性（R² = 0.19；P = 0.017）。
该问卷能够可靠地测量全膝关节置换术前患者的期望；然而，仍需要进一步研究。尽管我们预期年龄较小与期望较高有关，但全膝关节置换术前较高的功能似乎与较高的期望更密切相关。
