I am 10 weeks out from double TKR and 3 weeks out from MUA. I'm still experiencing the burning on the sides of the knees and across the patella. PT tells me the same, "be patient and see how it goes". At 3 1/2 weeks out it sounds like you are doing great!

@kapkalkac Although I did not have burning after either of my TKRs, from what I hear it is not unusual. Your numbers are great for three weeks out. I am sure the burning will end within the next couple of months, if not sooner than that.
Let us know when it finally feels better so we can celebrate with you! 😉
JK

I am 5 weeks out and the intense burning is terrible. I am going to see my doc tomorrow. I had my other knee done twice and do not remember this type of pain. Feel better

You are at 115° flexion after 3 1/2 weeks surgery?....i am 7 1/2 weeks from surgery and assisted flexion can get at 107° and 0° extension. I have another 4 weeks PT
My age is 78. I don't know what flexion I can get on my own, but I am hoping for more. My lower leg and knee get so hard it feels like a wedge at the lower part if the petellar tendon but after it gets warmed up I can walk pretty well. Good for you

About the burning in another post...I had the horroble burning stinging sensation around my knee which was worse during the time my leg was at rest. After 4 weeks, it tapered off. My other knee kneeds to be replaced but I'm going to have a solid case of amnesia before that happens.sounds like you had the best of outcomes as you could have. Best to you
