I am a firm believer in PT. I had to request a 'script from my surgeon and his advice was to take it easy at first, listen to my body and don't do anything that felt wrong. There were many range of motion restrictions to begin - 90°, inward rotation, crossing legs etc.
Starting with home visits, I soon was given the green light to advance. At around 6 week post op I began pool training at our local Sports Medicine & Orthopedic Center. These guys regularly work on Olympic athletes, US Ski Team members and really know their stuff. They were excited to have me there for they don't see many hip resurfacings.
I moved to the dry land stuff a few weeks after getting in the pool. I would spend a couple hours a day, three days a week on strength, range of motion and massage routines. This was followed by 15 minutes in their new ice rig that completely wrapped the joint and circulated ice water in the device.
In total I must have had 35+ sessions for each hip with lots of "homework," which included many miles of walking. I loved it and think it helped get me back in shape for the things I want to do; hiking, biking, skiing, climbing, motorcycling etc.
