ASTM F1814: Standard Guide for Evaluating Modular Hip and Knee Joint Components  


To investigate the interlocking strength of modular tibial PS and CR inserts several static tests can be used. A static axial load is applied either onto the edge of CR insert or by a defined lever arm onto the tibial post of PS inserts. Load is applied in posteroanterior, anteroposterior, mediolateral, lateromedial (if asymmetric knee) and tensile direction.
In general six samples are needed for each test.
