The proportion of bone resorption area.
After implanting tibia baseplates, the proportion of bone resorption area was analyzed a) in overall area of proximal tibial plateau, b) in the medial and lateral compartment, and c) in the four areas of proximal tibia.

The material composition of four implants were changed from cobalt-chromium (CoCr) to titanium (Ti) and vice versa while maintaining the design of the implant.
The proportion of bone resorption area after implanting four original and four altered tibial baseplates was analyzed in a) overall and b) medial and lateral compartment. The amount of bone resorption change was analyzed after changing the material composition in c) overall and b) medial and lateral compartment”, the material composition of tibial baseplate is changed from CoCr to Ti.

The amount of change in proportion of bone resorption after exchanging tibia implant from cobalt-chromium to titanium and vice versa.
Fig 5.
The proportion of bone resorption area after implanting four original and four altered tibial baseplates was analyzed in a) four areas in proximal tibia. The amount of bone resorption change after exchanging the material composition was analyzed in b) four areas in proximal tibia, the material composition of tibial baseplate is changed from CoCr to Ti.
