Hi. I’ve had both knees replaced twice over the last 16 years. The key things I’ve found are 1) physio. If ur lucky to get on nhs great but def worth paying for if you can. I wasn’t walking straight after last op and was told I needed to strengthen side leg muscles. Just straight leg raises laying sideways on bed. This sorted problem. Exercises need to be done regularly for the rest of our lives. I made that mistake first time round and thought that after x weeks of physio I’d be like new. I now realise that’s not the case and do little bits everyday.
2) I visit a chiropractor who has helped straighten me out and walk straight.
The physio May be able to help with treatment for your hip problem as well.
Please contact me again if I can help more 😀
