Hey Linda, I had an MUA a few weeks ago, I was 6 months out, I am 54 by the way. I walked from the car when I got home, the same day, and up the stairs to my bed for a couple of hours sleep. Then I went downstairs for a few more hours. Yes I was sore and stiff, but it was bearable with painkillers. not as bad as I had thought it would be. I heard the scar tissue tearing away, I also had an epidural, it was like velcro pulling away. He got it to about 110-120.
The next morning I was at physio and I got from my previous 93 to 97 degrees ROM. Had another session of physio 2 days later, same 97. Last week I was at 100 and this week 102. I also go to aquafit twice a week now and one PT. I still have to do the exercises and stationary bike at home and my hubby pushes my knee at night. I am at -3with extension. I can walk down the stairs almost properly, but it still hurts and I still have to hold on tight. I still have a lot of stiffness in my knee, but I know it will go one day.I think I am finally seeing light at the end of this tunnel. I had problems with swelling which is why it has taken this long. It is wonderful not having the joint pain anymore, I am really pleased I had it done.
I will need the other one done in the future, but am coping with the cortisone at the moment, but I wouldn't hesitate to get it done when that time comes. I am hoping to be able to dance with my hubby again at our friends wedding next week.
You already have 103 ROM so you should do really well. Good luck and let us know how it goes.
