City Hospital is very well known for Joint Replacement Center in Dombivli West Total Knee Replacement (TKR) is actually misleading as your whole knee is not replaced! It only involves resurfacing the cartilage on the 3 bones where they move against each other. The new surfaces are made of metal and polyethylene and are fixed to your bones with special bone cement. The implants we use are imported, have been well tested, and have been used successfully for many years.
