Zusammenfassung:Multivariate analysis showed failure was associated with age under 70 (OR 1.8), BMI over 35 (OR 1.6), pre-op deformity greater than 11 degrees (OR 2.5), implant poly thickness greater than 12 mm (OR 2.4), postop alignment less than 2.5 degrees of valgus (OR 2.4), and female gender (OR 1.7). Small femur on big tibia was associated with lower risk of revision for both implant designs versus size matched implants (Design #1, HR = 0.474, p=0.0007; Design #2, HR = 0.136, p=0.0002).
