I have had both hips replaced. The right hip was replaced on April 12th of this year and it was an anterior procedure. I played a bridesmaid luncheon three weeks after that. Of course, I had to have help loading and unloading the harp but otherwise it was fine. The first hip replacement was done in December of 2011 and it was a posterior procedure. I do not rightly remember how long it was after the surgery that I was able to play, however it was not very long. Having had both, I would recommend the anterior as it does not involve as much muscle and the incision is much smaller, thus the healing time is shorter. Anyway, best of luck.
