When we have the second surgery, we are not in the greatest condition as we were when we had the first surgery. The baby exercises they gave me on the first surgery were actually difficult on the second surgery because so much had deteriorated. I suspect that is your problem too.. Walking won’t fix it, though the exercises specifically to strengthen the muscles that surround your hip or what is super important the first few months out of each surgery. I suggest you return to your surgeons office and get referrals for physical therapy or home visits by nursing or rehab. I had them and they were really critical to getting back to walking without supports. It is really important to work with a trained professional that knows which of your muscles need improving and how to stabilize you and who can give you exercises to do every day for a while so you can gain your independence back. I’ve had five different joint replacement surgeries and using the doctors, nurses and skilled professionals that are at your disposal are super important. They are a good source of support too! Good luck!
