Diurnal Variations in Articular Cartilage Thickness and Strain in the Human Knee
Jeremy L. Coleman,Margaret R. Widmyer,Holly A. Leddy,Gangadhar M. Utturkar,Charles E. Spritzer,Claude T. Moorman,Farshid Guilak,Louis E. DeFrate +7 more
TL;DR: The findings of this study show that human knee cartilage undergoes diurnal changes in strain that vary with site in the joint, and provides a baseline for future studies investigating the effects of altered biomechanics on diurnal cartilage strains and cartilage physiology.

Mechanical properties of normal and osteoarthritic human articular cartilage.
Dale L. Robinson,Mariana E. Kersh,Nicole C. Walsh,David C. Ackland,Richard de Steiger,Marcus G. Pandy +5 more
TL;DR: The results identify the limits by which isotropic hyperelastic material models may be used to describe cartilage contact variables, indicating that the mechanical properties of cartilage for large strains change with tissue damage.

In Vivo Measurement of Localized Tibiofemoral Cartilage Strains in Response to Dynamic Activity
E. Grant Sutter,Margaret R. Widmyer,Gangadhar M. Utturkar,Charles E. Spritzer,William E. Garrett,Louis E. DeFrate +5 more
TL;DR: Local regions of both the femur and tibia experienced significant cartilage strains as a result of dynamic activity, and an understanding of changes in cartilage strain distributions may help to elucidate the biomechanical factors contributing to cartilage degeneration after joint injury.
