I used to sell hip and knee implants to Dr's and hospitals. In the winter in the NE they would line up 5-7 surgeries a day after a snow storm after all the old ladies fell and broke their hip. They can resurface a hip or cut off the top of a fumur and install in a few hrs. depending on the pain he will be a lot better off. Sitting, walking driving, crapping, everyting is effected by a bad hip.
Tell him to do some research and pick a hospital and a Doc that does many a day. Any doc will be installing what they learned on in thier residency so a orthopedic surgeon in a busy practice is a must.
I sold for DePuy that was bought by J&J and now have a class action big lawsuit against them. Zimmer is another leading mnfctr from Indiana that has good info:
