Total Knee Arthroplasty (TKA) is performed more in working-age (<65 years) patients. Until now, research in this patient population has been conducted mainly among retired (≥65 years) patients. Aim of this study was therefore to describe demographic, physical, psychological and social characteristics of working TKA patients and to subsequently compare these characteristics with retired TKA patients and the general population.
A cross-sectional analysis. Preoperative data of 152 working TKA patients was used. These data were compared with existing data of retired TKA patients in hospital registers and with normative values from literature on the general population. Demographic, physical, psychological and social (including work) characteristics were analyzed.
The majority (83.8%) of working TKA patients was overweight (42.6%) or obese (41.2%), a majority (72.4%) was dealing with two or more comorbidities, and most (90%) had few depressive symptoms. Mean physical activity level was 2950 minutes per week. Compared to the retired TKA population, working TKA patients perceived significantly more stiffness and better physical functioning and vitality, were more physically active, and perceived better mental health. Compared to the general population working TKA patients perceived worse physical functioning, worse physical health and better mental health, and worked fewer hours.
This study shows that a majority of working TKA patients are overweight/obese, have multiple comorbidities, but are highly active in light-intensity activities and have few depressive symptoms. Working patients scored overall better on preoperative characteristics than retired patients, and except for physical activity scored overall worse than the general population.
全膝关节置换术（TKA）在工作年龄（<65岁）患者中实施得更多。到目前为止，针对这一患者群体的研究主要是在退休（≥65岁）患者中进行的。因此，本研究的目的是描述在职TKA患者的人口统计学、身体、心理和社会特征，并随后将这些特征与退休TKA患者及一般人群进行比较。
横断面分析。使用了152例在职TKA患者的术前数据。这些数据与医院登记册中退休TKA患者的现有数据以及来自一般人群文献的标准值进行了比较。对人口统计学、身体、心理和社会（包括工作）特征进行了分析。
大多数（83.8%）在职TKA患者超重（42.6%）或肥胖（41.2%），大多数（72.4%）患有两种或更多合并症，且大多数（90%）有轻微抑郁症状。平均身体活动水平为每周2950分钟。与退休TKA人群相比，在职TKA患者感觉僵硬更明显，但身体功能和活力更好，身体活动更活跃，心理健康状况更好。与一般人群相比，在职TKA患者感觉身体功能更差，身体健康更差，但心理健康状况更好，工作时间更少。
本研究表明，大多数在职TKA患者超重/肥胖，患有多种合并症，但在轻度强度活动中非常活跃，且抑郁症状轻微。在职患者术前特征总体得分比退休患者更好，除身体活动外，总体得分比一般人群更差。
