I had my TKR surgery on 10th May (aged 74) and am now half way through week 4 of my recovery. The surgeon had to do quite a lot of work on my knee as the arthritis was severe and the kneecap had moved. I’m not sure if this explains the excruciating pain I was in when the anaesthetic wore off! For pain relief I was on codeine, paracetamol plus, for 14 days, aspirin and omeprazole. However, the painkillers made me feel dreadful - dry mouth, nausea, constipation, loss of appetite. I couldn’t eat and lost weight (21 lbs so far). The only positive thing was that the painkillers also made me feel sleepy so I pretty much slept my way through the first couple of weeks. I had no problem getting up and down stairs and moving around on my crutches. I was also able to manage some of the exercises, but bending my knee to get the 90 degree angle was just way too painful. I was beginning to feel really depressed about this as I’d been led to understand that the post-op exercises were crucial. I then came across this website and what an enormous relief it was to read the advice not to push through the pain and that the knee would eventually get the ROM needed in time. This week I reduced the codeine during the day and feel so much better. I’m now able to eat a little more and I’m on track with the “daily living activities” I should be doing by week 4. I’m feeling much more positive and so pleased to have discovered this forum.
