From what I read on this site this is a sensitive subject, but since this site is all about information I wanted to relate my recent experience.
My right hip was resurfaced 2.5 years ago by Dr. Callendar in San Francisco, using a posterior approach. Recovery was fairly quick and, to date, I have no complaints.
My left hip was done 3 weeks ago by Dr. Raterman in Tampa. He offered me the option of an anterior approach, which I took, as it offered a slightly quicker recovery. He explained that he can only do the anterior approach for certain patients. The criteria was a reasonably large bone structure, muscular but not too muscular, and fairly lean. I'm certain that evaluation is done on a patient by patient approach.
The surgery went fine. I transitioned from a walker to a cane as soon as I got home, and went off the cane at 7 days post op. I was on an exercise bike at 10 days post op, and on my bicycle at 11 days post op. The 90 degree restriction was lifted at 14 days. The range of motion increases, and the pain decreases, daily.
The best way I can think off to describe the recovery is that it was like starting at day 8 on my recovery from the other hip. I was able to sleep in my bed immediately, where I slept in a chair for 8 days before. I was off the walking aids about a week sooner, and on my bicycle about a week sooner.
There are no real negatives that I can report. The skin over my quad is a little sensitive, and the amount of feeling when I touch the skin is ever so slightly less than the other leg, although it is still early days. While waiting for the doctor at the 2 week followup I studied the x-ray showing both of my hips at length. As closely as I can tell, the angle of the cap to the cup is the same, the pin from the cap is inserted at exactly the same place in the femur and at exactly the same angle. The doctor said the x-ray looked terrific.
This is just my experience and YMMV.
