Q. My cat is 15 and has a problem with his back legs !! They look like the pop out of place when he is walking Also drinks a lot of water !! HELP !!

A. The hip abnormality is probably happening as a result of massive weight loss and muscle wasting. Him drinking a lot of water could be due to renal failure, diabetes, hyperthyroidism or other internal diseases.
Your cat needs help but we cannot help you with this matter remotely, you will need to go to the vet in order to diagnose the condition and treat it accordingly.
