Table 7.18: Revision rates of uncemented knee systems by implant model at 5 years of followup.
Estimates were calculated using Australia (AU) and Emilia-Romagna (ER) register data.
Knee system (uncemented)
Key: obs. = number of observations; CI = confidence interval; G.M.T. = Global Manufacturing Technology.
The horizontal black line indicates lack of overlap (portion below) by prostheses with other registry data.
