A single impact at 27 J of energy with a rigid interface was delivered to one knee of isolated joint preparations of six cadavers resulting in an average peak load of 5 kN. Contralateral knee were impacted with a padded interface at an additional level of energy at approximately the same load. Math modeling of the patellae showed reduced tensile and shear stresses in the bone with padding. Increasing contact area over the knee reduces stresses in the bone and prevents both gross bone fracture and bone and cartilage microdamage.
