As you recover from hip replacement surgery, if you live alone, family and friends could help set up a "base camp" where you'll spend most of your time -- with phone, computer, remotes, and everything else you'll need in easy reach.
They could also remove tripping hazards like loose rugs, help pick out helpful gadgets like reachers, and set up stairway and bathroom railings.
If you don't have a support system you can rely on, ask your doctor if you could stay in a rehab center after surgery.
