The primary objective of total knee arthroplasty (TKA) is to decrease pain and restore functional knee joint. Current hypotheses indicate higher knee flexion is required in terms of life style, culture and expectations in Eastern communities. Therefore, society-specific features related to life style and cultural habits are needed. The objective of this study was to investigate the expectations of patients undergoing TKA.
The study included 131 patients (18 male, 113 female; mean age: 66.2 ± 8.3 years) who underwent cemented TKA due to knee osteoarthritis. All patients were operated by the same surgeon using the same implant and surgical technique. Patients were evaluated using the Hospital for Special Surgery (HSS) knee score, a 15-item clinical knee assessment questionnaire and the HSS knee arthroplasty expectation questionnaire.
Mean HSS score for the right knee was 89.2 ± 10.5 and for the left knee was 89.6 ± 9.4. The two most expected outcomes were improvements in pain (99.2%) and gait (96.2%) and the two least expected outcomes were improvements in psychological well-being (22.9%) and communicative skills (35.1%). Expectations were not affected by education and working conditions.
Patients' most expected outcomes were improvement in pain and restoration of function (gait, climbing stairs and no need of assistive devices), similar to Western and American communities.
全膝关节置换术（TKA）的主要目标是减轻疼痛并恢复膝关节功能。当前的假设表明，在东方社区，就生活方式、文化和期望而言，需要更高的膝关节屈曲度。因此，需要考虑与生活方式和文化习惯相关的特定社会特征。本研究的目的是调查接受TKA的患者的期望。
该研究纳入了131例因膝关节骨关节炎接受骨水泥型TKA的患者（18例男性，113例女性；平均年龄：66.2±8.3岁）。所有患者均由同一位外科医生使用相同的植入物和手术技术进行手术。使用特种外科医院（HSS）膝关节评分、一份包含15项内容的临床膝关节评估问卷以及HSS膝关节置换术期望问卷对患者进行评估。
右膝的平均HSS评分为89.2±10.5，左膝为89.6±9.4。最期望的两个结果是疼痛改善（99.2%）和步态改善（96.2%），最不期望的两个结果是心理健康改善（22.9%）和沟通技巧改善（35.1%）。期望不受教育程度和工作条件的影响。
与西方和美国社区类似，患者最期望的结果是疼痛改善和功能恢复（步态、上下楼梯以及无需辅助器械）。
