## 5 Conclusions  
In this study, the overall qualitative evaluation of the MCCT and UCLA sockets was presented in terms of the effects of the socket on the residuum's geometrical changes. The results showed that the simulations and measurements for every subject exhibited considerable correlations and similarities. The FEM model created by the suggested method possessed various similarities with the real residuum. The differences detected were attributed to post operation scarring and to some merged skin on the residuum that cannot be created by the meshing method in the 3D construction. The calculation of geometrical changes was completed based on the bipedal stance condition, which has been extensively used in previous studies [13; 16]. The increased correlation of the FEA and IP pressure outcomes confirmed that the finite element pressure distribution was reliable and could support the research objective.  
The study also showed the efficiency of the FEM model created by the proposed method as an evaluation tool for the socket before its fabrication with 3D printing. The system was initiated to help engineers and manufacturers undergo an evaluation procedure before the transfemoral socket was fabricated by the 3D printer. Even though the simulation ignored the relative movement between each part inside the residuum, the results are still promising because the deformation of the residuum depends on the fluid movement inside the soft tissue parts [20]. The system is low-cost and

low-maintenance and has user friendly interfaces with an added value for prostheses and fabricators to run as an evaluation system. The system was also able to reduce the time consumption during the fitting sessions and the number of sessions required for each subject. According to the promising results of this study, the system can potentially serve as an alternative method to the evaluation of the prefabricated socket. The use of the system and its capabilities is envisaged to allow the pursuit of numerous other research studies to evaluate the transfemoral socket and their uses for the determination of the level of deep-tissue injuries that occur inside the socket and in any other soft tissues of the human anatomy involved with the application of external forces.
