I had a dull nagging pain in my left knee last four years. X-rays showed some arthritis. Dr. Linford explained to me very professionally how a new knee someday would take care of the problem. We agreed with my age and time frame of being a farmer and rancher that I could get a lot of comfort with therapy and a steroid injection. It feels better already, and I haven't started treatment yet. I owe this to Dr. Linford and his staff. Many Thanks.
