Finite Element Modeling of Meniscus Tears

Knee biomechanics · Computational modeling · Cadaveric testing

After tearing my ACL and meniscus in a soccer injury in 2023, I joined the UIC Orthopedics Research Lab. I worked on computational models and physical tests to study knee injury mechanics and how meniscal damage changes joint contact.

01 / Model

From DICOM scans to a knee model

I reconstructed joint anatomy from DICOM imaging, prepared the geometry in ANSYS SpaceClaim, and set up finite element models for injury-relevant loading.

The CAD assembly represented the knee structures needed to examine load transfer through the joint. I prepared the geometry for analysis and created intact and meniscus-injury configurations.

02 / Load cases

Compare intact and injured knees

I analyzed the models under different loads and orientations to examine how tear location and severity affected joint contact mechanics.

01 / REFERENCE

Intact knee

Baseline model for comparison with the injury configurations.

02 / TEAR SEVERITY

33% · 50% · 83%

Radial tears modeled at different portions of meniscus width.

03 / COMPARISON

Meniscectomy

Total medial meniscectomy included as a comparison condition.

Radial tear locations

Anterior horn of the medial meniscus · midbody of both menisci · posterior horn of the lateral meniscus

03 / Validation

Connect simulation with physical testing

I compared the model results with cadaveric experimental data to help interpret joint behavior under injury conditions.

Cadaveric knee testing

I designed mechanical fixtures for cadaveric specimens and supported testing of the ACL, patella, femur, and associated ligaments.

Using the NDI Optotrak 3D optical tracking system, I analyzed motion data to quantify joint kinematics under applied loading.

What the comparison showed

Comparing finite element results with cadaveric experimental data provided insights into injury mechanics and the effect of meniscus tears on contact mechanics of the joint.
