Aloha Dr.Bose,
My post op update:
I have had a remarkable experience as I have had no problems at all.I have been a bit Conservative with my exercises but as of last week I walk atleat two or three miles on the beach daily.I have never had pain or swelling since the surgery.
Dr.Bose,and Mohan,
It has been almost two and a half years since I journeyed to Chennai for my Birmingham hip replacement, and for the most part things are good with my new hip joint. The experience has had a profound effect on my life. I have since cut my long hair, and am still living in Alaska and enjoying my mobility once again. In the past few years I have had a return to pain free activities.
