Bonnet, chief surgeon at the Hotel Dieu in Lyon, proved experimentally that the characteristic postures assumed by tubercular joints were caused by the accumulation of fluid in the joint.
"By injecting fluids under pressure into the capsules of the joints [of fresh cadavers], he observed that the limbs assumed the positions that permitted the greatest amount of fluid to be injected. He also noted the points of rupture, or the weak spots, in the capsule. He correlated all his findings with clinical observations on his patients" (Peltier, p. 149).
Bonnet also used fresh cadavers to demonstrate the mechanics of meniscal injuries, comparing the varying effects of forced extension, forced flexion, varus and valgus stress, and rotation of the knee in cadavers of all ages.
"Like Malgaigne in Paris and Hilton in London and many others, Bonnet was an apostle of rest for joint disease, fixing the joints proximal and distal to the diseased joint. . . . [He] wrote on every aspect of joint disease, thus orienting the Lyons school towards orthopaedics and its apogee under Ollier" (Le Vay, p. 260; see also p. 259).
