It is possible to give chimps medical treatment without anaesthetic blow-dart knock-downs, at the cost of a lot of training time for the chimps and staff. At the Ape Rescue Centre in Bovington, UK[0], chimps are trained using clicker training [1] to present their arms for injections on a routine basis so that when an anaesthetic is required, the chimps aren't subjected to a blow-dart but to a seemingly normal injection. Some primates still require knock-downs but it is not routine.
