When I had my last 3 hip replacement surgeries, once the surgeon determined that the implant was successful, and I still had back and knee pain, I was referred to a rehabilitation center for physical therapy. He explained nicely that it is his job to put the parts in properly, but my job, in conjunction with a physical therapist, to make sure it works as well as it can.
I went to not just a PT in a "cookie cutter" practice, but someone who actually did a thorough evaluation of my body, gait, posture and listened to me. She explained that I had been limping/compensating for years for the bad joints, and needed to learn how to use the new ones, much the same way and amputee needs to learn to use a prosthesis. Then she designed a custom PT program that included land and water therapy, gait training, daily exercises.

That was 10 years ago, and now any pain comes from progressing arthritis or doing something I shouldn't. Do you think you could benefit from work with a good PT?
