The Prosthetic Legs and Arms Act (PLAA) sets up a no-fault compensation program for persons injured through the use of medical prostheses. The PLAA protects prosthesis makers from liability for unavoidable side effects. When Quint is injured in an auto accident, his physician prescribes and fits him for a certain prosthetic. When Quint suffers injuries from its use, he, files a suit against Replacement Limbs LLC, the maker of the prosthetic, alleging strict product liability. Is there a defense that Replacement Limbs might successfully assert in this case? If so, what is it, and why?
