Can we declare Annulment of marriage due to medical issue

Hello Everyone, After 4 months of marriage I found there is big medical issue in wife. Doctor told to do operation for shoulder bone and they will replace the part of it. As the same issue is started to hip joint bone as well. The part which have to replace having 15 years of lifetime, after 15 years we have to replace it again and the main issue is she is 23 years old only, But if the operation not done there are some issues that she have to face and it can be goes some critical medical issues. This issue was not aware by the wife family itself. While getting married, we was not aware about this issue. But after 3 months we found its a big problem. When we asked Doctor they told it is started 1 years back. Because of this issue can we declare marriage as Annulment of marriage ? It is very difficult to survive with this many medical issues. As after operation she cant work as usual, there are some restriction that she need to be care. Your reply will be more valuable for me. Thank You.
