Plasma-treated hydrogels have been put forward as a potential selective osteosarcoma therapy through the release of reactive species to the diseased site. To allow their translation to the clinics, it is crucial to show that the oxidative stress delivered by such hydrogels does not adversely affect healthy tissues. This is evaluated here by investigating the in vivo performance of a robocasted calcium phosphate cement infiltrated by a plasma-treated hydrogel. The plasma-treated composite implanted in a critical size bone defect of healthy rabbits revealed its safety, allowing equivalent bone ingrowth compared to the control scaffolds and to that of direct plasma treatment of the bone defect. This opens the door for using composite biomaterials containing plasma-generated reactive species in bone therapies.
