I had a total hip replacement by Mark Wagner December of 2016. Before surgery my legs were different lengths from crushing my femur and gait issues from severe arthritis - I couldn't walk across a parking lot. He perfectly fixed the 1/2" leg length difference. 2 weeks after surgery it was better than before. 5 years later it's stronger than it has been since I was much younger - I can hike, x-country ski, race bikes, ... I cannot recommend him highly enough.
