I have arthritis and my right knee was painful. ago Dr. Schaeffer performed a simple procedure on my right knee. I had physical therapy, and during follow up visits, he removed fluid and gave me a cortisone injection. Despite all of this, the pain did not diminish. I have been advised by several physicians that I might benefit from partial or total knee replacement, but I am so terrified of another surgery as I feel I may become paralyzed. WOSM does not accept insurance, and is extremely expensive. I would never go to WOSM even if they are the last physicians left on earth!
