Try a cane first. A cane can help take some stress off a healing limb or joint. One can use a walker first, then a cane, and then hopefully nothing. . . As he heals up. If a person has a permanent deficit and can never walk limp-free without a cane, perhaps a cane is still helpful to let his body move in a more "normal" way, if the cane lets him walk limp-free. A physical medicine (rehabilitation) doctor can help!
