Abstract:
The purpose of this descriptive correlation research aimed to study the relationships between age, gender, body mass index, congenital disease, severity of pain, depression, and social support for the activities limitations in olders persons after a total knee arthroplasty (TKA). The sample group consists of 120 persons aged 60and over who suffered from primary osteoarthritis and underwent a TKA. The paticipants had a follow up 3 months after the procedure at 3 different tertiary hospitals, where the following data were collected using demographic questionnaire, Body mass index (BMI), Severity of pain rating scale, Thai Geriatric Depression Scale, Social support assessment, WOMAC 5-point Likert. The statistical analysis was performed to obtain frequency, ratio, mean, standard deviation, range, Pearsons Product-Moment Correlation Coefficient (r) and Spearman rank correlation coefficient (rs). Major findings were as follows: 1. Olders persons after TKA experienced moderate level of activities limitation. 2. The level of depression and severity of pain had significantly moderate positive correlation with activities limitation after TKA at the level of .05 (r = 0.652, r = 0.625 respectively). 3. Social support had significantly low negative correlation with activities limitation after TKA at the level of .05 (r = -.191). 4. There is no correlation between age, gender, BMI and congenital diseases and the activities limitation in olders persons after TKA.
