I went through a series of the lubricating injections and had several cortisone injections, but neither had lasting effects. As a last resort, I decided on the total knee replacement and am very pleased and thankful with the outcome. Home Care Physical Therapy and Outpatient Physical Therapy were outstanding as well as the individual home exercise program I was instructed to do. It has been three and a half months and I am pain free and very happy with the results!
