The influence of BMI on the eventual outcome following total knee revision remains uncertain. Several studies have compared obese and nonobese patients with conflicting results. Amin,^[6] in his study of 41 morbidly obese patients, demonstrated that one third of the patients developed radiolucent lines on radiographs at 5-year follow-up. Patients who are morbidly obese have lower activity levels that may not compensate for the higher stresses across the tibial component. This may explain the high rate of radiolucent lines and aseptic loosening in this patient population.^[6,7,8]
