I had both my knees done 3 yrs ago.
I still have soreness and pain in them and stiffness.

Stretching and keeping on doing the physical therapy exercises tends to ease the pain and stiffness somewhat when I actually do them.
The cold weather makes them hurt and ache a lot more.

My knees are still better than they were before surgery. I can walk and get around better.

It can take time for healing. A year to two years. Some people more than others. I know someone who had his knees done about six years ago. He has no pain at all. Nothing.
Me after 3 yrs. still have some level of pain.

I hope yours will improve. I'm sure it will. Keep doing the PT at home and maybe massage in the soft tissue area. You can still use cold pack or heat. Anything that brings some relief.

I hope your appointment goes well and you do not have any complication.

Good luck.

Thank you for your response. I must admit I have not been very faithful about exercising my knee. The reason is that the sciatica on that side has been very annoying since the surgery and I am now concentrating on physiotherapy and exercises for that problem. I had sciatica prior to the surgery but it certainly got much worse.
I am grateful that my knee does not give out as it did before so I no longer have to be afraid of falling.

I totally understand. it's difficult when we have multiple problems. We work on one area of body that needs therapy but another area needs attention too but we have only so much energy and it's hard to keep up with it all.
I have knees to exercise, fingers/hands, Shoulder, back, all these areas I've had PT for and I am meant to keep up with the exercises.
And other areas hurt too that I'm sure need working on like my hip.
It's a juggling act.

I hope your sciatica eases up for you. You do what you can. That's good about your knee not giving out.

Good luck.

I saw the surgeon yesterday and he says mechanically everything is in order with my knee. It should last 20 to 25 years so it will outlast me! He acknowledged that there is still some swelling and the knee still feels a bit warm but he expects that to go. The funny thing is it ached like crazy for the rest of the day and this morning it feels very stiff. Of course we are to get a huge rain storm so that may be the reason. I hope it will get better than it is right now.

Hi ingelo
That's good the knee is ok and nothing wrong mechanically. I'm sure the swelling and pain will subside over time.
The weather may play a part in increased pain. My knees hurt more due to weather changes, barometric pressure, they respond more to the weather far more than they use to before surgery.
I wish you continued healing and success.

@Csk
There's no cartilage left in a knee that has had a TOTAL knee replacement.
