@grandmabv I see what I wrote was confusing. Medicare does not pay for MFR (myofascial tissue release unless the problem is due to damage originating from the spine) You can read more about it here. It seems that there is a 10 - 15 minute allowance for manual manipulation as part of Physical Therapy but again, it has to meet the requirements. https://resonancemyofascialrelease.com/is-myofascial-release-therapy-covered-by-medicare/
on top of that, you have to find someone who can do it and accepts insurance!
I am concerned that you have swelling and are tight. I don't think you should have the swelling. I'd like to suggest you see your surgeon sooner, rather than later. You shouldn't have the swelling. It also seems like you should be in PT TWICE a week. I know my PT recommends that for rehab after surgery until the muscles are strengthened. I have known NO ONE EVER who had to wait 1 - 2 years for their knees to be better. Its pretty routine and you shouldn't be feeling stiff for six months. You should have it in the rearview mirror in a year. My neighbor had BOTH knees done at 83 and was mowing the lawn 6 weeks later!!! Crazy!
Return to your surgeon for post surgery follow ups. I had those at 3 weeks, 6 weeks, 6 months and 1 year. There is only one person I knew who had stiffness, pain and swelling such that she couldn't cope with it. This is not entirely unusual and there is a treatment where they put you to sleep and then bend the knee and get it moving. She was better after that work was done. We do all heal at different rates, but its the swelling that concerns me. You sound like you are doing all the right things. looked up the procedure my friend had and its more common than I thought, so I hope you will check into MUA:
"A manipulation under anesthesia (MUA) is a non-invasive procedure that can help restore knee movement after surgery. During the procedure, you are put to sleep while your doctor gently bends and straightens your knee.
What it does
Breaks up scar tissue or adhesions that limit movement
Reduces pain and stiffness
When it's done
Sometimes performed after a total knee replacement if the knee becomes stiff
After surgery
You should follow your doctor's advice for the best chance of a full recovery
Avoid bending your knee in an uncontrolled way
Don't sleep with a pillow under your knee
Keep your knee as straight as possible while sleeping
Other tips
Use commercial breaks to help gain the bend in your knee
Sit in a chair that allows you to slide forward while keeping your feet firmly planted on the floor
Bend your knee as far as you can on your own"
Good luck!
