Ok. This is something new??
No, it's not something new. It's just a matter of how your surgeon and PT were trained.
I had my first knee replacement back in 2000 and my surgeon then had the same policy as my current surgeon.
My surgeon doesn't allow any PT at all for the first month after a knee replacement. He says your knee needs that time, to start on its journey of healing. For that month, we rest, ice and elevate our leg, and walk around the house.
After that month, we just go to PT once every 2 weeks, where we are shown a few new exercises to do at home.
His patients all do well and achieve good ROM, as I did, and he hasn't had to do a manipulation to help with ROM for the past 4 years. I think that speaks for itself.
First off let me say I’m doing a bit better. 5wks I still have a 70 ROM but I’m gradually graduating to the cane. I have permission to use it in the house just not outside. Still have my”blue” days.
Now I’ve noticed that several times a day it feels like my knee gives out or buckles when I’m walking. I know the new knee is stable. But could it be because of my “Dead Leg , Dead Quad” or what ever it’s called.
I'm glad you're doing better.
I must say though that while you still feel as if your leg is going to buckle, it may be too soon to graduate to the cane. There's no set time when you should change from one walking aid to another. It's a matter of safety. Use what you need to, to prevent a fall. And you don't need permission to move from one walking aid to another. You do it when you feel that both you and your knee are ready and will feel safe.
