Thank God I found this site. Just a little update I've had a lot of starts and stops since my TKR on Nov 27th, 2018. I fell on my but day 2 in hospital, good thing I had some padding. Xray looked good. Stayed 2 nights in hosp because nerve block did not take- much pain. After arriving home, day 4 ended up in ED due to excessive vomiting, wretching and severe headache. I was told was a spinal headache, got rehydrated, recieved wonderful IV morphine and steroids, released feeling soo much better. Once home and on regular doses if Morphine, became severely constipated. Doc told me to use Miralax and mineral oil enemas- did the trick but had to repeat several times. Home PT very gentle. Had me mostly walking outdoors. 3 weeks later PT outpatient, not too bad. Last week PT decided to get more aggressive, omg, caused pain. I told them to never do that again, and they responded. Still doing all exercises without over exerting. My question now is my kneecap doesnt seem to be tracking properly, started to notice at week 2 . PT seems to think it will resolve with time and quad strength, feels like its catching, causes pain and inability to bend. OS agrees with PT, says I need to strengthen quads. Any one else?
