I am 11/2 year out from have a Partial Knee replacement with a Staph infection, and then having to let another Surgeon dig it out 6 mths later, and put in a Totaland that has been a one year last week. I have been in PT with the total 3 times now, I'm in there still ! My New Doctor, who is awsome, told me the normal time for healing in Patient is 8 months to a year, with Heat and Swelling . I have fallen on several times, thank goodness I would throw my body in any direction to not hit that bad Knee. My Range of motion like yours is very good. I find that the Knee cap popping is louder than the sounds I had before, I know the pressure you are talking about, I have ask him , my PT. and they say it is the Knee Replacement,Knee Cap and the tissue swelling. I have been reading past Post and have read some stories of People that are 2 Years out in more Pain now than ever. You are only 3 months out, you still have more time to heal, and are in a critical stage of watching how you twist and lift things, not to do anything to loosen it. I've been in PT with some People that are doing really good after 4 weeks, but I think as time goes on and we get back to a"Normal" life, something changes. I know the Doctors are awsome , but I don't know how they can tell you as an individual how long it wil take you to heal. Until they have one done to themselves, don't tell me I shouldn't have Pain and why is the Pain level so high ? I know I have gone through a little different situation than you, with the first partial with staph, which was not opened up and irrigated, and having to have it become grossly loose to where I couldn't walk, to a Total put in 6 mths later. I just pray I find a time I won't be in this Pain, and can get back to Walking my Dog, or going upstairs, getting my balance back. I don't know if you feel like you have a bulk inside there that is knocking you off balance or if is that just me? Give yourself sometime, read some old post, and I pray everything goes good for you . Not trying to get you down, just wan't to be honest. I will never do my Left Knee, and wish I hadn't done this one !
