<human>: Can you provide a brief rundown of the text in within 3 sentences?

Dear Reddit,
I am a long time lurker who made an account a few weeks ago. I guess I am posting here cause I have no where else to really turn. Last night my sister called and told me my 62 year-old mother was crying. This never happens, my mother is a very strong woman. To explain all of this might take a while, so strap yourself in if you care to. 
Six years ago my mother broke her hip. She had surgery to correct it but they had to shave off bone to fit the hip. She had to walk with a cane and now one of her legs is inches shorter than the other. This eventually caused my mother's knees to wear out. They bend in, making her have legs shaped like this "><". She was in constant pain and eventually got cleared for two knee replacements. One was completed over two months ago and she has patiently waited for her upcoming surgery. 

Now her surgery is a week away and the doctor called alerting her that they want to postpone it again. My mother was defeated, broken and in more pain than I could imagine. This news was the last thing she could hear after months of excruciating pain and disability. The reason they want to postpone surgery is that my father works in hardware store and his insurance is changing. It takes effect January 3rd but the surgery is the 7th and doctor refuses to see if it clears. The insuarance company is being no help as well.

Reddit, I don't know what to do here. My mom has been the one person I can always go to and now she seems just broken by the news. Is there legal recourse? Can we start a campaign to help her? The surgery is $35,000 and my parents simply can't afford that.
<bot>: My mother's seriously needed knee surgery is being set months away because my father's insurance is in limbo. WHAT DO?!?
