Nanoindentation of the insertional zones of human meniscal attachments into underlying bone.
The fibrocartilagenous knee menisci are situated between the femoral condyles and tibia plateau and are primarily anchored to the tibia by means of four attachments at the anterior and posterior horns. Strong fixation of meniscal attachments to the tibial plateau provide resistance to extruding forces of the meniscal body, allowing the menisci to assist in load transmission from the femur to th...
متن کاملAnisotropy Nanoindentation Properties of Human Cortical Bone
INTRODUCTION Cortical bone is an anisotropic material, and its mechanical properties are determined by its composition as well as its microstructure. On the microstructure level (a few microns), cortical bone is composed primarily of single osteons and interstitial lamellae. Nanoindentation has been shown to be an effective technique to probe mechanical properties of microstructures at the micr...
متن کاملNanoindentation of the Human Femoral Head
The mechanical aetiology and progression of osteoarthritis in articulating joints is not fully understood. We have characterised the variation in the nanoindentation stiffness of articular cartilage in non-OA and OA human femoral heads. The superior region of the head is stiffest, and where most loss of cartilage is seen. The region surrounding the fovea capitis is most compliant and may show s...
متن کاملHistological Analysis of Human Meniscal Allografts
Background: Little is known about the biology of meniscal allograft transplantation in humans. In particular, little information is available about the phenotype of the cells that repopulate the allograft, whether an immune response is elicited against the graft, and whether the repopulating cells synthesize normal extracellular matrix components. Methods: A small biopsy specimen of the menisca...
متن کاملSurvival analysis of human meniscal transplantations.
We describe a prospective survival analysis of 63 consecutive meniscal allografts transplanted into 57 patients. The lateral meniscus was transplanted in 34, the medial meniscus in 17, and both menisci (combined) in the same knee in six. For survival analysis we used persistent pain or mechanical damage as clinical criteria of failure. A total of 13 allografts failed (5 lateral, 7 medial, 1 med...
