Development and Biomechanical Evaluation of a Modular Knee Prosthesis: From Conceptual V1 Design to an Improved V3...

Area of Science:

• Biomedical Engineering
• Orthopedic Technology

Background:

• Current knee prostheses face limitations in functional capabilities and accessibility.
• There is a need for cost-effective, anatomically compatible prosthetic solutions.

Purpose of the Study:

• To design and evaluate a three-stage prosthetic system (V1-V3) for improved performance.
• To develop a cost-effective knee prosthesis with high kinematic accuracy and modularity.

Main Methods:

• Technical review of existing commercial prostheses.
• Computer-Aided Design (CAD) modeling using SolidWorks.
• Kinematic evaluation via Motion Simulation and experimental testing of the V2 prototype.

Main Results:

• V1 design showed structural limitations; V2 prototype demonstrated improved assembly and function.
• The V3 concept achieved advanced mechanical behavior with an extended range of motion.
• V3 offers reduced mass, a lower center of gravity, and smoother dynamic response.

Conclusions:

• The V3 knee prosthesis design is a promising engineering solution for clinical application.
• This study lays the groundwork for a fully modular lower-limb prosthetic platform.
• The developed system enhances prosthetic functionality and anatomical compatibility.
