Better Outcomes in Severe and Morbid Obese Patients (BMI>𝟑𝟓kg/m^𝟐) in Primary Endo-Model Rotating-Hinge Total Knee Arthroplasty

Table 3

Changes in WOMAC score adjusted for preoperative status and patient age for each of the factors studied. Results are expressed as mean and 95% confidence interval. Age was not statistically significant in the fitted model (𝑃=0.097). The initial WOMAC score was statistically significant in the fitted model (𝑃<0.001).
