Joint Awareness is thought to be closely linked to Quality of Life (QoL) for patients undergoing Total Knee Arthroplasty (TKA), yet to date there have been no longitudinal studies to explore how Joint Awareness actually affects QoL. The purpose of this study was therefore to examine the development of Joint Awareness and QoL after TKA as well as the dynamic impact of Joint Awareness on QoL.
A total of 342 patients were followed up at 3 months (T1), 6 months (T2), and 12 months (T3) after TKA. Joint Awareness was evaluated using the Forgotten Joint Score-12 (FJS-12), and QoL was measured by SF-36. We used repeated measures analysis of variance to estimate the development of Joint Awareness and QoL and employed a cross-lagged model to examine the dynamic relationship between Joint Awareness and QoL.
Both Joint Awareness and QoL improved with postoperative time (p < 0.001). Importantly, T1 Joint Awareness positively predicted T2 physical QoL (p < 0.001), and T2 Joint Awareness positively predicted T3 physical QoL (p < 0.001). Nevertheless, Joint Awareness had no predictive effect on mental QoL (p = 0.082-0.931).
In different periods after TKA, Joint Awareness and QoL both increased monotonically, and Joint Awareness positively predicted physical QoL. These findings indicate that focusing on Joint Awareness may be a priority when trying to improve the postoperative life of patients.
关节意识被认为与接受全膝关节置换术（TKA）的患者的生活质量（QoL）密切相关，但迄今为止，尚无研究探讨关节意识如何实际影响 QoL。因此，本研究旨在探讨 TKA 后关节意识和 QoL 的发展以及关节意识对 QoL 的动态影响。
共 342 例患者在 TKA 后 3 个月（T1）、6 个月（T2）和 12 个月（T3）进行随访。使用遗忘关节评分-12 分（FJS-12）评估关节意识，使用 SF-36 评估 QoL。我们使用重复测量方差分析来估计关节意识和 QoL 的发展，并使用交叉滞后模型来检查关节意识和 QoL 之间的动态关系。
关节意识和 QoL 随术后时间的推移而改善（p<0.001）。重要的是，T1 关节意识正向预测 T2 躯体 QoL（p<0.001），而 T2 关节意识正向预测 T3 躯体 QoL（p<0.001）。然而，关节意识对心理 QoL 没有预测作用（p=0.082-0.931）。
在 TKA 后的不同时期，关节意识和 QoL 均单调增加，关节意识正向预测躯体 QoL。这些发现表明，在努力改善患者术后生活时，关注关节意识可能是优先事项。
