Welcome, Protruck, and good luck.
Here are a few things on the top of my head.
1. Do you have a recliner (Lay-Z-Boy)? That was my favorite, most comfortable place to be for the first two weeks. If not, get or rent one.
2. Set up a small table nearby, where you can keep your a) remote control, b) a drink, c) a laptop or iPad, d) books/magazines. You'll want to stay put and off of your feet, initially.
3. Icing: You'll need to ice constantly post-op, pretty much for two straight weeks. Have enough handy so that there's always a cold pack available. If you get a polar ice machine (Dr. Gross patients typically get one), you'll need a LOT of ice to keep it cold.
4. Rugs and clutter: I didn't have any issues with throw rugs tripping me up, but I also had my wife around to get me things, and my dad came in to help for the first 2 1/2 weeks. If you're by yourself, you may want to clear the floors.
5. Raised toilet seat. It it a necessary curse. I hated it, but can't imagine getting down/up from the toilet in the first 4-5 weeks.
6. You need other aids for daily living: something to put on socks, a grabber is handy for when something falls on the floor, a sponge-on-a-stick for showering (to get at your lower legs).
There is a lot of good information here

I'm sure some other single folks will chime in. The more help you can get, the better (for about 10-14 days).
