I used a walker for the first week. Many folks do not. At week two I used a cane but was directed by my PT to use it on my non-affected leg out to the side, not close to my body, for balance and weakness.
But remember I waited 14 years, yes 14 years, before having this surgery. What a mistake!
So I have a lot of weakness from years of compensating with the rest of my lower body. From weeks 3-6 I used the cane mostly for the first few steps upon standing and when walking outside and practicing on uneven grounds like grass. I also took it on walk "just in case". Really meaning if I walked to far and needed a little help getting back.
I have found that three walks a day, not long ones, is the best thing for me. Taking care to extend in the back with the top of my leg and not my pelvis. This is the direction my own OS gives the PT's he works with.
PT is also important but for cramping and pain (not like the pain you're having now but the post operative pain) but for me walking short walks is the best.
But again I have been off balance and weak for many years.
But the walker and the cane have both been mainly for balance and weakness.
Rotating ice around the operative area not leaving it on for more than 20 minutes in one spot has been very good for me. But my OS doesn't want ice on any one spot for longer than 20 minutes right now.
Remember you will have swelling in the area after surgery so that limits you a little but that varies with everyone.
Set up your side table though. I like a basket. My meds, a water bottle, TV remote, book, pens, phone, computer and charger near by etc...I like a basket because nothing falls to the floor and make sure you get one of those picker upper things. Even if you only use it for a week. Also the body pilloe which I got a target and a few pillows for you head/shoulders
You really have to rest your body in the time immediatley afterwatds. So do it. Rest, ice, little walks, elevation
