did you take any medicines during last so many years ??
There are several good medications to control this disease from progressing but the damage cannot be reversed unfortunately.
Yes surgically there are many options available. Joint Replacement
can be an option for us. But i recommend you to start good medications first and then go for surgery. Because disease progression has to be stopped first./////////////
Also take good NSAIDS or painkillers and cartilage
repairing medicines by consulting a physician that suit you best.
