"On December 3, 2013, Dr. Brian Schafer replaced my left knee. After 3 weeks and 2 days, I was walking without a walker or cane. I had very little pain from the surgery to completion. Everything went so well and I am having Dr. Schafer do my right knee. The key to a knee replacement is your pre-operation and post-operation exercises. I can highly recommend Dr. Brian Schafer of Advanced Orthopedic Specialists." -- Norman L.
