Knee Replacement Surgeon In Dombivli| Total Knee Replacement Knee Replacement is essentially a resurfacing operation in which the diseased and worn out parts of our thigh and shin bone are removed at a pre-determined specific angle, inclination and thickness, such that the remaining bone can accept an artificial anatomically shaped femoral ( thigh ) and tibial ( shin ) component. These components are cemented in bone with a special bone cement and a plastic insert is placed between these components. The undersurface of the knee cap is also generally resurfaced with a plastic component.
