I have arthrictis in my knees. the left one is worse and tho its not bone to bone yet could i still have surgery on it? i've had couple shots in my knee and don't want anymore. id like to have the surgery if i can.

Depending : Depending on the severity of the arthritis, you have several "surgical" options. Especially if you have any cartilage/meniscus tears in addition to the arthritis, you could consider a simple arthroscopic "clean-up" surgery. This is most successful when the arthritis is relatively mild and there are mechanical reasons for your pain such as a meniscus tear or loose body, etc. Generally speaking, joint replacement surgery (total or partial knee replacement) is reserved for when non-surgical options fail to provide adequate relief, although there are even less invasive options such as "arthrosurface" which is when the arthritis or cartilage defect is focal and isolated. The smaller area where the cartilage is thinning or damaged can be replaced by a small piece of metal or plastic instead of replacing the entire joint. Not all orthopedic surgeons do this type of surgery though, as it is relatively new.

Yes: That is reasonable at your age to go ahead and replace the knees if advanced arthritis- does not have be completely bone-bone if you have tried other methods of treatment
