Since your meniscus is pretty much gone, you are walking bone on bone, which can wear down the joint and cause pain, swelling, inflammation, a shortened leg (resulting in hip and back pain)and other problems
. It is probable that if this surgery fails, your ortho will recommend a total knee
replacement. There is a "new" knee out there that is placed orthoscopically and gives the client more range of motion. I am not sure of the name, but ask your doc about it when the time comes.
