BMI does not impact knee range of motion, gait speed after TKA

Patients saw improvements both biomechanically and clinically following total knee arthroplasty regardless of BMI, according to recently published results.
Researchers evaluated 79 patients with clinical gait analysis before total knee arthroplasty (TKA) and 1 year after TKA. They assessed gait velocity, knee range of motion (ROM), gains, WOMAC score, quality of life and patient satisfaction. Investigators evaluated comparisons between patients with obesity, patients without obesity and healthy controls. They used univariate linear regression analysis and multivariate linear regression analysis to assess the correlation between gait speed and ROM gains.
Patients with obesity had significantly lower gait velocity and knee ROM at baseline compared with patients without obesity. According to results from univariate linear regression and multivariate linear regression, there was no significant association between gait speed gain, knee ROM and BMI. Patients with obesity vs. those without obesity were more symptomatic at baseline, with significantly higher improvements in WOMAC pain. – by Monica Jaramillo
