Methods of treating bone defects include autogenous bone and allogeneic bone transplantation, tissue engineering technology, gene therapy, growth factor and adjuvant therapy of physical therapy, etc. However, most treatment schemes have obvious disadvantages. The purpose of this paper is to study the application of graphene-based nanomaterials combined with early exercise rehabilitation training in the treatment of patients with infectious bone defects. The biomedical properties and biomedical applications of graphene are briefly introduced through literature research and investigation, and bone defect diseases and commonly used treatment methods are analyzed. Graphene is used in many biomedical fields, such as disease diagnosis, biosensing, antibacterial and antiviral materials, cancer targeting, photothermal therapy, drug delivery, cell electrical stimulation, tissue engineering, stem cell technology, DNA sequencing and fluorescent (FL) tracking molecular probes. The effects of graphene-based nanomaterials and rehabilitation exercise on the treatment of infectious bone defects were compared through controlled experiments. The results show that although the repair effect of graphene-based nano-materials is not as good as that of autogenous bone, the difference is not significant, and it is better than calcium phosphate cement. After rehabilitation exercise, the curative effect of graphene experimental group was improved. In the 12th week, the tensile strength reached 5.78 N, and the torsional strength reached 0.93 N m, which exceeded the group of autogenous bone without rehabilitation exercise. This paper discusses the strength-related repair effect, but the in vivo toxicity of graphene needs further study.
