My veterinarian said I have patellar luxation!

I was at the veterinarian for a routine checkup. I was surprised to find out that I have a condition known as patellar luxation. I didn't even know my patellar's were having a problem! Patellar luxation means that my kneecap will move out of its joint sideways. I found out that I am not alone. Many other small breed dogs suffer from this problem. Especially pomeranians, toy poodles, and chihuahua dogs. Right now I don't feel any pain. I'm not sure what to do. My veterinarian said he can fix my patellar luxation with surgery. I am worried about it, as I do not have any insurance. It will cost $1000 for each kneecap. The veterinarian recommends surgery on both of my back legs. That would be $2000! Sheesh. I better start saving my mommy's money!
