| dc.description.abstract | total knee arthroplasty (tka) is an orthopedic surgical procedure designed to alleviate the effects of knee osteoarthritis (oa), aiming to enhance patients' strength, range of motion (rom), and ability to perform activities of daily living (adl) post-operatively. lifestyle risk factors and comorbid conditions are factors thought to impair recovery following tka. therefore, this research aimed to investigate the effect of lifestyle risk factors and the presence of comorbidities on both pre-operative and post-operative tka patients, specifically evaluating their ability to perform functional tests.
participants completed the stair climb test (sct), stair climb power test (scpt), and six-minute walk test (smwt). the study analyzed lifestyle risk factors and comorbidities alongside functional test scores collected before and six-months after tka surgery. a two-way mixed factorial anova was employed to assess the impact of smoking status, alcohol consumption, and the presence of comorbidities on functional performance measures, while a bivariate correlational analysis examined the relationship between bmi and performance outcomes.
28 participants completed the study. non-smokers recorded the fastest time in seconds (s) on the sct, scpt, lowest average power in watts (w) on the scpt and furthest distance walked in meters (m) on the smwt compared to smokers/former smokers, both pre- and post-operatively. smokers/former smokers averaged an improvement of 31.2% across all testing postoperatively with non-smokers improving averaging an improvement of 22.6%. for alcohol consumption status, non-drinkers recorded the fastest time for the sct (s), scpt (s; pre- and post-operatively), and highest average power on the scpt (w; pre- and post-operatively) compared to drinkers.
