ABSTRACT

Objective: To study the difference of tibial osteotomy coverage between symmetrical prosthesis and asymmetrical prosthesis, and to further demonstrate the necessity of designing asymmetrical prosthesis and anatomical prosthesis. Methods: 3D simulation technology was used to simulate the operation to obtain the parameters of tibial osteotomy surface of each patient, and five kinds of prosthesis were used for optimal coverage. Finally, the coverage difference of tibial osteotomy surface of each prosthesis was analyzed. Conclusion: 3D simulation technology is an important means to study tibial osteotomy surface, which is worthy of further promotion and research.
