Abstract
To study the effect of obesity on clinical and radiographic outcomes of computer-navigated knee arthroplasty. 117 patients underwent primary computer-navigated total knee arthroplasty. Eight were lost to follow-up and 8 had incomplete data. Eighty-four (83.2%) female, 17 (16.8%) male patients age 65.3 ± 6.9 years with a pre-operative BMI 27.2 ± 4.1 (18.6-40.0) kg/m<sup>2</sup>, 7.3 ± 0.98 years follow-up. Forty-two (41.6%) had a BMI>27.5 kg/m<sup>2</sup> indicative of obesity in Singapore. Post-operative radiographic alignment, 2-year Oxford knee scores and ROM were not significantly associated with BMI. BMI is not a determinant of functional scores when computer navigation is used.
