Cindy,
Do you live alone? Remember the first week you will be in the hospital for approx 4 days. You will definitely need help the first week you are home. Make sure you have loose fitting shorts that go above the incision as you won't want anything touching that area for a while. You can just wear a gown, but it's uncomfortable during physical therapy being exposed if you know what I mean.
I did get a short summer hair cut before my surgery and I'm so glad I did. I was unable to shower for the first few weeks and had to go awhile without washing my hair. UGH!
Make sure you have a chair that sits higher with arms. I do have a glider rocker, but it's difficult to get out of without help, because it rocks when I don't want it to. It is good for rehab though because it gives you a natural bend while rocking.
You may come home with a CPM machine. You will need help getting into it for the first week or so. Plus it's necessary to have someone to lift it and put it on the bed for you then get your leg situated. You will use it for a couple of hours 3 x a day to get maximum results.
Make sure your bed is on the lower level if you have an upstairs. Stairs will be difficult to climb initially. Also if you can move your bed closer to the bathroom, it will make it easier to get around. Set up a table next to your bed to hold all your medicines and a water bottle within easy reach.
As for the walker, I didn't like mine and only used it as long as was necessary. I found it to be cumbersome, however I did get along well with crutches. They were easier to maneuver on the carpet and on different surfaces.
And yes, the ice is for your knee. You will need to ice regularly 5-6 times a day. Wrap the ice in a towel before applying so you don't burn your leg. You will need to ice on top and behind the knee. I was able to purchase a knee wedge to elevate my knee to help with swelling. Pillows will help, but they are hard to get situated under the covers without assistance. Mostly make sure you are comfortable and have everything you need within reach as you won't want to get up to hunt anything for a while.
The last thing I would recommend is some vitamin e capsules to apply to the scar, once the wound is sealed. I puncture one and apply it liberally on the scar while massaging. Your home therapy will show you how to do this properly.
Keep plenty of juice and fresh fruit, on hand. It is refreshing to eat and gives you added energy, plus it doesn't require cooking!
I was fortunate to have my husband home for the first 3 weeks. He was wonderful to take care of my every need.
Hope this helps some. I am sure the others will have some added advice to help out. Hope your surgery goes well with no complications.
Blessings,
