For severe arthritis - how will knee replacement surgery help? My mother is suffering from severe arthritis and the doctor has recommended this surgery? Presently my mother can walk with support - will this surgery help her to walk without support? Her ligaments in the knee area has weakened. Even if the knee is replaced - will she be able to build back the ligaments that had atrophied?

I am planning to take her to the Philippines. How soon can she come back home to the US after this surgery?
