Dr. Brooks in the Cleveland CLinic has done over 500 hip resurfacings and does the anterolateral approach. He is the most experienced surgeon in this area. You can view his video here
http://www.surfacehippy.info/shvideos/videosdoctor.phpFrom my experince of learning about hip resurfacing for the last 5 years, having the posterior approach and talking personally to many surgeons and attending the Hip Resurfacing courses - I can say the approach has little to do with your recovery.
I know may people with very fast and easy recoveries with the posterior approach including myself. I was released from the hospital in 2 1/2 days - stayed at the Holiday Inn in Belgium with 8 other patients. We partied the night of our release and every night after that. We ate all our meals in the dinning room. I was on one crutch as were the other 7. Even one of the bilaterals was only using one crutch. I was sight seeing 5 days post op. Had no brusing or swelling after surgery - same with all of us. Was walking over mile a day when I came home 9 days later after an 8 1/2 hour flight from Beligum to Ohio. I did not need the one crutch after 3 - 4 weeks. Just kept it with me on long walks.
So approach has nothing to do with recovery. The major factor in recovery is the surgeons skill. If you take time to read the hundreds of stories an posts both here and on the Yahoo surfacehippy Discussion Group - you will see the trends over and over. Use the most experinced surgeons and normally, there are always a few exceptions, but normally the top surgeons patients have good recoveries. It takes time to read the thousands of stories as I have, but you learn a lot. That is why I choose Dr. De Smet of Belgium - he had done over 3000 hip resurfacings and his patients have wonderful outcomes. I was with 7 others so I know it personally.
Take time and learn about the surgeons. Be sure to ask your surgeon for the names of 3 or 4 patients you can talk to. Ask them how their recoveries were. Ask all the questions and make sure you feel good about the answers. If that inner voice is saying it is not sure - then look elsewhere. If you like the surgeon, then go with your decision. It is all up to you. Since you are asking for other patients input - I am guessing you have not been given names of other patients. Call the surgeons office and ask for the names of other patients to contact. The doctor and his office staff should be very helpful in answering all your questions. The top surgeons will bend over backwards to answer your questions and make you feel at ease about your surgery.
