We suggest that obesity may impair the early outcome of total knee arthroplasty and obese patients should be informed about the increased risk of complications related to TKA. Key words: Total knee arthroplasty; body mass index; obesity; complications; range of motion; mechanical axis.
Background and Aims: Obesity has been linked to the development of osteoarthritis of the knee and since the incidence of obesity is increasing, the need for total knee arthroplasty (tka) is likely to increase. conflicting findings have been reported concerning the relationship between obesity and tka. it has been shown in several studies, that obese patients have poorer clinical results after operation. On the other hand it has also been reported similar results for obese and non-obese patients. the purpose of this study was to analyze clinically and radiologically the results of total knee artrhoplasty in obese patients.Material and Methods: the study consisted of 48 patients who had a tka. the patients were divided in two groups according their body mass index. patients of bmi over 30 were regarded as obese.Results Conclusions: Obesity has a negative impact on the outcome of tka, assessed by patients' clinical function and satisfaction level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
