This is a very common question patients ask before surgery. As a knee replacement surgeon I usually make them understand that surgery is meant for pain relief, improve mobility and hence quality of life
Indians are fond of doing basic day to day activities on floor. This need almost full 0 to 160 range of motion that was not possible with older implants. Also I discourage it because it might increase wear of the new joint.
With recent hi-flex implant designs and good physio may help in doing even floor activities.
