Is that the one with the spinal operation? It's been a while since I watched TNG.
In that episode, Crusher was right to tell the other quack off. THe second doctor was lucky that her unproven, untested procedure didn't leave Worf dead for real. The ends do not justify the means. Had that been a human/Betazoid/Vulcan/Xenexian patient without "redundant" internal organs, she would have just signed their death warrent for the sake of testing her unproven experimental theory.
