Thanks for the information. I am a little confused about what is a complete recovery. I have been able to do most things since three months or earlier, but still have some nagging discomfort later in the day.
I have trouble lifting and walking up full sized stairs in the normal way. II have walked 3-5 miles in a day on some occasions but could walk up to 10 before. if I sit in a restaurant, I need to stand and stretch about every 30 minutes, which is probably a good idea anyway. My surgeon says I need to be patient for a few more months, but I am not clear if that is true, or is this basically a full recovery (or less likely, is something not right). I am scheduled to talk to another skilled surgeon, but really want to know if my recovery is off, or is the advertising off. I think there is no easy answer.
First, you're right. There is no easy answer.
Even though your hip probably looks normal from the outside, muscles, tendons and other soft tissues are still healing and adjusting to the new way you're walking.
All the things you can't yet do, but you used to be able to do, indicate that your recovery isn't yet complete.
Your surgeon is correct in saying you need to be patient for a few more months. Most surgeons are reluctant to do any further investigating or surgery before a year post-op, simply because many things that seem to present a problem sort themselves out with time. That's all part of the normal healing process.
Your body needs to adjust to the different forces now acting when you walk - and you still need to be able to walk without a limp. Before your surgery, your body was trying to protect your painful hip and, unconsciously, you probably adjusted your gait to do that. Now, you have to learn how to readjust your gait, so you don't limp.
As for the advertising, yes, I think it's probably a bit over-optimistic. They're looking at the first 3 months of recovery, assuming that most healing has taken place - and it has. But after that there's the much longer period, where progress is slower and much less obvious improvement is made. I think of it as a two-stage process - 80% done and a slower 20% still to achieve.
Try to remember that where your hip is now is not where it's going to end up. It will continue to improve, but more slowly than before.
