Shanghai MicroPort Orthopedics evaluated fixed-bearing versus mobile-bearing total knee replacement implants using the Abaqus Knee Simulator. The tool enabled semi-automatic FEA modeling of tibiofemoral kinematics, contact mechanics, and component stresses under gait and squatting loads. Results showed no significant performance advantage for mobile bearings and reduced the need for physical prototyping and mechanical testing.

Key takeaways

AKS enabled dynamic FEA of FB and MB TKR designs under physiological loads

Mobile bearings showed only marginal rotation gains with no clear performance edge

Simulation setup time dropped from one week to one to two days versus manual modeling

FEA reduced reliance on physical prototypes and Kansas Knee Simulator testing

Squatting loads relevant to Asian markets were modeled alongside standard gait cycles
