Abstract:
BACKGROUND: There are a variety of methods for establishing periprosthetic osteolysis animal model, and the models established by different methods and with different animals have their own characteristics.OBJECTIVE: To review the research profiles of the periprosthetic osteolysis and the characteristics of the various models, and to provide a reference for the related research. METHODS: The relevant articles on the periprosthetic osteolysis animal models were searched in PubMed from January 1999 to May 2017, with the key words of "animal model, osteolysis" in English by the computer. Similarly, Chinese Journal Full-text Database was retrieved for related articles published from January 1999 to May 2017, with the key words of "animal model, osteolysis" in Chinese. Articles that were unrelated to the periprosthetic osteolysis animal model were excluded. Classic and recently published articles were selected. RESULTS AND CONCLUSION: (1) The artificial induced animal models are the principal means to establish animal models of periprosthetic osteolysis and they have been widely used in the study of periprosthetic osteolysis pathogenesis, pathological process and treatment. (2) Small-animal models present many advantages: inexpensive to purchase, high physiological turnover, controlled source, homogenous and established genetic background. However, a limitation of these small-animal models is that the temporal pattern of osteolysis is different from the long-term osteolysis that occurs in patients. (3) The large animal model is more similar to the bone dissolution process around the human prosthesis, but the cost is high; the breeding is difficult; the operation requirement is hard. Thus, its widespread use is limited. (4) Furthermore, innovative models that combine the advantages of both are also constantly explored. Overall, the selection of models should be based on research conditions and needs to be considered.
