Preoperative characteristics of working-age patients undergoing total knee arthroplasty

Abstract

ObjectiveTotal 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.MethodsA 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.ResultsThe 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.ConclusionThis 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.

Health Status of Total Hip Versus Total Knee Arthroplasty Patients and Possible Effects on Decisions Regarding Surgical Location, Cost, and Access to Care

“…Much research exists on health status for TJA patients as it relates to postoperative outcomes, but studies on preoperative health status differences between THA and TKA patients is scarce. A prior study comparing retired (> 65 years) to working-age (< 65 years) patients undergoing TKA evaluated several health parameters and found that younger TKA patients were largely overweight or obese, and the majority had > 2 medical comorbidities [8], consistent with our findings. Another study sought to determine the quality of life in patients on a TJA waiting lists and found that 63% of patients had cardiovascular disease, 33% had high blood pressure, 33% had diabetes, and 33% had endocrinologic issues [16].…”

Customised, individually made total knee arthroplasty shows promising 1-year clinical and patient reported outcomes

“…The demographics of the included patients do not fully overlap with the average patients undergoing TKA. Indeed, the former are younger and have a lower BMI, while the male gender is overrepresented [48][49][50].…”

The relationship between mental health/physical activity and pain/dysfunction in working-age patients with knee osteoarthritis being considered for total knee arthroplasty: a retrospective study

“…Our study was a secondary analysis of data derived from a public database, the Work Participation In Patients with Osteoarthritis cohort study [ 12 ]. Overall, 152 (65 men and 87 women) patients with KOA with preoperative employment, being considered for TKA, with a mean age of 55 years (standard deviation (SD) = 5.5, range, 28–63 years) and complete preoperative information, were enrolled.…”
