SolidWorks Modeling Brief – Simplified Total Knee Implant for FEA
Budget: £20 – £250 GBP
I require a simplified, simulation-ready 3-component total knee implant model created in SolidWorks. The purpose of this model is comparative mechanical testing and material evaluation using Finite Element Analysis (FEA). This is not for surgical planning or regulatory medical design, so the focus must remain on correct mechanical behavior rather than full anatomical or surgical detail.
Project Scope
Please model the following three components as separate native SolidWorks part files:
Femoral Component
Tibial Tray (Baseplate)
Tibial Insert (Polyethylene Spacer)
A patellar component is not required.
Design Intent
The model will be used to:
Apply physiological loading conditions
Compare candidate biomaterials
Evaluate stress, strain, and contact pressure distribution
Therefore, the geometry must accurately represent load-bearing shapes and contact mechanics, but does not need surgical-level anatomical detail.
Geometry Requirements
Femoral Component
Accurate external condylar curvature to represent realistic rolling contact with the insert
Smooth transitions and fillets; no sharp edges in load-bearing regions
Realistic overall proportions and thickness
No internal lattice structures, porous coatings, fixation pegs, or bone-ingrowth textures
Tibial Tray
Anatomically reasonable top outline (oval/kidney shape acceptable)
Flat upper surface to support the insert
Central stem or peg for realism (simple cylindrical geometry is sufficient)
No screw holes, porous coatings, or fine surgical features
Tibial Insert
Must match the tray footprint
Upper surface must include a curved groove or concave profile compatible with the femoral condyles
Smooth contact surface is critical
Uniform, realistic thickness
Level of Detail (Important)
Include:
Correct global geometry
Realistic contact surfaces
Smooth filleted edges
Watertight solids suitable for meshing
Do not include:
Bone-cut interfaces
Cartilage layer modeling
Ligament attachment points
Surface textures or roughness
Microscopic features
Internal porous structures
Assembly Requirements
Deliver:
Individual .SLDPRT files for each component
One .SLDASM assembly file
Assembly must:
Be fully constrained and error-free
Position components in correct functional alignment
Allow contact definition between femoral component and insert
Model Quality Standards
Fully parametric feature tree (no imported “dumb” solids)
Clean sketches with proper relations and dimensions
No surface gaps, self-intersections, or failed features
Geometry suitable for direct FEA meshing
FEA Preparation
Please also provide either:
A duplicate configured assembly prepared for simulation
or
A SolidWorks Simulation study with placeholder mesh, contacts, and fixtures (these will be refined later).
Materials should not be permanently assigned, as multiple biomaterials will be tested.
Deliverable Purpose Reminder
This is an engineering test model for structural simulation and material comparison, not a clinically validated implant design. Prioritize mechanical realism, clean geometry, and simulation stability over anatomical surgical detail.
Please confirm understanding of the simplified scope before proceeding.
