I was diagnosed with Osteonecrosis 2015. Cortisone injections only lasted about 4 weeks. January 2016 I had my first TKR. I Exercised regularly with a PT and at home. Pain got so bad I had MUA July 2016. That did not help and my bend was practically non-existent. I was referred to a different Consultant. August 2018 I had a revision. My bend was slightly better but not 100%. I still had pain on weight bearing but I kept up my regular exercises. My balance was not good and I had a few falls. One 3months after my op and because I was on blood thinners my leg was purple. I had a fall August 2019 and fell on my TKR and landed on my face luckily on grass but I ended up with slight concussion and whiplash and a headache for two weeks. I phoned my GP who said that my knee was obviously suffering from trauma and to wait and see if the pain improved after a couple of months. A year has now passed and with COVID it is difficult to get an appointment with my GP. My pain is getting worse and leg gives way now and again which is frightening. I can’t go out without my husband’s support. I am at the end of my tether. Only appointment I can get from my local surgery is a telephone consultation. Can I request a scan to find if there is any damage done to the implant. I am 78 and can’t go on like this much longer. I need answers soon. Can anyone give me advice.
