Stability Simulation Analysis of Unicondylar Knee Prosthesis

Abstract: Unilateral knee replacement surgery is a commonly used treatment for knee osteoarthritis, but if symptoms of knee instability occur, it will seriously affect clinical efficacy. Due to the large amount of equipment required for stability research, evaluation requires a significant amount of resources. This study evaluates the stability of unicondylar knee prosthesis through finite element analysis, simulates the geometric shape of unicondylar knee prosthesis, and analyzes the stability performance of the finite element model using axial compressive loads and anteroposterior (A-P), medial lateral (M-L), and medial lateral (I-E) movements. Evaluate the stability of the geometric shape of unicondylar knee replacement, and design a unicondylar prosthesis that better restores natural knee joint mechanics, meeting clinical usage requirements.
