I had my TKR on April 3rd. Started PT the following week. I'm currently able to go UP stairs with little problem. Coming DOWN is still a challenge, to say the least! I still sleep on my back, can't seem to manage the side, even with a pillow between the legs, and that's a real shame, because the side is my preferred sleep position. Now, lets talk about pain med. I tried cutting back a week ago. NOT a good decision on my part. My surgeon prescribed 1-2 7.5mg Percocets every 4-6 hours, not to exceed 12 a day. Well, trying to "stay ahead of the pain", I was taking 2 every 4 hours, even setting the alarm at night to wake up and take them. My previous script was for 100 pills. Taking them like that, they ran out in about 8 days! This concerned me. I went to my regular Dr., and he decided that I needed 5mg, taken 1 per 8 hours. HUH??? Needless to say, I didn't fill his script, as my surgeon had sent me another script same as before. I want to cut back, but don't want to sabotage myself. Other than that (ha!), I think I'm doing well enough. My flexion has gotten up to about 95-100 on good days.
