Goals

• To examine changes in strains within the menisci associated with gait changes.
• To develop a finite element model of the knee and compare model to a cadaveric specimen imaged in different kinematic positions in an MRI.

Major Findings

• External rotation and an increased adduction moment resulted in higher strains overall in the medial meniscus and lower strains in the lateral meniscus.
• External tibial rotation caused a decrease in strains in the posterior medial horn and increased strains in the anterior medial horn.

Representative Publications

• The effect of kinematic and kinetic changes on meniscal strains during gait.
