Total knee arthroplasty (TKA) aims to alleviate pain and restore function in patients with knee osteoarthritis. While the Forgotten Joint Score (FJS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) are established measures of patient satisfaction and functional outcomes after TKA, they may not directly capture the patient's subjective perception of the joint itself. The FJS was used to assess concurrent validity, as it reflects the degree to which patients are unaware of their artificial joint, which is related to joint perception. The patient's joint perception (PJP) question offers a simplified alternative to evaluate joint awareness.
This prospective observational study included patients who underwent TKA between 2018 and 2023. An Arabic version of the PJP (Ar-PJP) question was translated using a forward-backwards translation process. Participants completed the PJP, FJS, and reduced WOMAC at two time points, three weeks apart. Statistical analyses assessed validity and reliability using Pearson's correlation coefficient.
A total of 100 participants were included in the study. The mean PJP score was 28.9 (standard deviation [SD]: 13.7), and the mean WOMAC score was 46.1 (SD: 17.8). A moderate negative correlation was found between the Ar-PJP score and FJS ( = -0.683; < 0.001), A moderate negative correlation was found between the Ar-PJP score and FJS ( = -0.683; < 0.001), while the correlation with WOMAC was weak and non-significant ( = -0.088; = 0.382), supporting discriminant validity.
The Ar-PJP is a valid and reliable tool for assessing patients' perceptions post-TKA. As a single-question measure, it simplifies evaluations and enhances patient care in Arabic-speaking populations.

全膝关节置换术（TKA）旨在缓解膝关节骨关节炎患者的疼痛并恢复其功能。虽然遗忘关节评分（FJS）和西安大略和麦克马斯特大学骨关节炎指数（WOMAC）是评估TKA术后患者满意度和功能结果的既定指标，但它们可能无法直接反映患者对关节本身的主观感受。FJS用于评估同时效度，因为它反映了患者对其人工关节的忽视程度，而这与关节感受相关。患者关节感受（PJP）问题提供了一种评估关节意识的简化替代方法。
这项前瞻性观察性研究纳入了2018年至2023年间接受TKA的患者。使用前后翻译法将PJP问题翻译成阿拉伯语版本（Ar-PJP）。参与者在两个时间点（相隔三周）完成了PJP、FJS和简化版WOMAC。统计分析使用Pearson相关系数评估效度和信度。
该研究共纳入100名参与者。PJP平均得分为28.9（标准差[SD]：13.7），WOMAC平均得分为46.1（SD：17.8）。Ar-PJP得分与FJS之间存在中度负相关（r = -0.683；P < 0.001），而与WOMAC的相关性较弱且无统计学意义（r = -0.088；P = 0.382），支持区分效度。
Ar-PJP是评估TKA术后患者感受的有效且可靠的工具。作为一个单问题测量方法，它简化了评估过程，提高了阿拉伯语人群的患者护理水平。
