You only had your TKR in mid-January, so it's only been 2 months. That really is a very short period of this year-long recovery, and it's too soon to start thinking that something is wrong.After all this time my right knee continues to wobble and give way in every direction. Some days are worse than others but basically I cannot go without crutches for fear of falling. Has anyone else experienced this? My mum also had the same surgery as me, 4 weeks after me and on the left knee however she has never experienced any letting go of the knee and is mostly walking without crutches by now (5.5 weeks post op). What is causing this? My Physio shakes his head and says it’s not normal and he doesn’t know if I will come good. I need to hear some positiveness please. Is there someone who had the same thing happening??? It also feels like the implant is moving or lose but Physio says that’s impossible.
And there is your answer! Your muscles were weaker and they have a lot more recovering to do before they regain full strength. Meanwhile, they aren't supporting your knee properly, so it feels unstable.I waited 6 years to do this and basically my muscles have wasted away during this long time.
If your physio is any good, knowing your past history, he will make allowances for it and stop telling you that what's happening is not normal. It is!
Give your knee a little longer, so that your muscles are stronger, and you could well feel that your knee is more stable. Just don't try to rush things.
Meanwhile, keep using the crutches, so you don't fall. Your knee will tell you when it is ready for you to give them up.
Don't compare your knee and your progress with your mother's TKR journey. No two knees are alike and no two recoveries are alike. For all you both know, your knee could have needed much more work during your surgery. I bet your mother didn't go into surgery with muscles already weakened by waiting 6 years for the surgery, either.
