Noninvasive Measurement of Meniscus Strain Using Hyperelastic Warping
نویسندگان
چکیده
INTRODUCTION The knee menisci are critical to the distribution of tibiofemoral contact stresses. This is demonstrated by the deleterious effects of injury or menisectomy on articular cartilage. Meniscus strains reflect load transfer and function in the normal and injured joint, and measurement of strain can be used to assess the efficacy of surgical repair techniques. However, in vivo measurement of strain in menisci is nearly impossible and in vitro measurements are difficult due to the limited access. The objective of this study was to validate the use of Hyperelastic Warping for noninvasive measurement of the deformation and strain distributions in the meniscus based on MR images.
