When will i be able to walk after knee replacement? how soon after knee replacement surgery will i be able to walk on my own?

Fairly quickly: Most knee replacement patients start physical therapy within a couple of days after sugery. You should be fully recovered by 2-3 months post-op.

6 weeks: All depend of the surgeon protocol and what kind of total knee was done.In general you should be able to start walkink with a walker 2d day after surgery with partial wb.You could be walking on your own probably after 4 to 6 weeks.
