Compression tests of human and bovine trabecular bone specimens with and without marrow in situ were conducted at strain rates of from 0.001 to 10.0 per second. A porous platen above the specimensExpand

A mathematical analysis for indentation tests of articular cartilage.
Abstract A mathematical model is developed for indentation tests of articular cartilage. The cartilage, normally bonded to the subchondral bone, is modeled as an infinite elastic layer bonded to aExpand

Bone compressive strength: the influence of density and strain rate.
The compressive strength of bone is proportional to the square of the apparent density and to the strain rate raised to the 0.06 power. This relationship is applicable to trabecular and compact bone,Expand

Differences between the tensile and compressive strengths of bovine tibial trabecular bone depend on modulus.
The conflicting conclusions regarding the relationship between the tensile and compressive strengths of trabecular bone remain unexplained. To help resolve this issue, we compared measurements of theExpand

Mechanical properties of metaphyseal bone in the proximal femur.
We used a three-point bending test to investigate the structural behavior of 123 rectangular flat plate specimens harvested from the metaphyseal shell of the cervical and intertrochanteric regions ofExpand

Patellofemoral contact pressures. The influence of q-angle and tendofemoral contact.
Controlled bending moments were applied to twelve human cadaver knee joints using a special loading fixture that allowed variation of both the Q-angle and the flexion angle. The joints were tested atExpand

Effects of loading rate on strength of the proximal femur
Results from previous quasi-static mechanical tests indicate that femurs from elderly subjects fail in vitro at forces 50% below those available in a fall from standing height. However, bone is aExpand

Prediction of femoral impact forces in falls on the hip.
A major determinant of the risk of hip fracture in a fall from standing height is the force applied to the femur at impact. This force is determined by the impact velocity of the hip and theExpand

Hamstring tendon grafts for reconstruction of the anterior cruciate ligament: biomechanical evaluation of the use of multiple strands and tensioning techniques.
BACKGROUND Our hypothesis that multiple, equally tensioned strands of hamstring graft used for reconstruction of the anterior cruciate ligament are stronger and stiffer than ten-millimeter patellarExpand
