“…The width of the radiolucent zone at the cementbone interface or the cement-stem or socket interface increases with time (DeLee & Charnley 1976) and the increasing width is associated with a greater amount of pain (Beckenbaugh & Ilstrup 1978, Carlsson & Gentz 1980. However there is no objective examination which is closely related to pain and clearly distinguishes painful hips in the patients with radiolucent zones.…”

“…The promise of engineered tissues is particularly attractive for applications such as ligaments, heart muscle and cartilage, which have a limited ability to regenerate, and for which there is a critical shortage of donor tissue available. One major challenge for orthopedic and cardiovascular applications in particular is that the engineered replacement tissues must function in complex and demanding mechanical environments, which can lead to implant failure under adverse conditions 9 .…”

Remodeling of Engineered Tissue Anisotropy in Response to Altered Loading Conditions

Structural and mechanical anisotropy are critical to the function of many engineered tissues. This study examined the ability of anisotropic tissue constructs to overcome contact guidance cues and remodel in response to altered mechanical loading conditions. Square tissues engineered from dermal fibroblasts and type-I collagen were uniaxially loaded to induce cell and matrix alignment. After an initial time, t*, of 5 to 72 hrs, loading was switched from the x-axis to the y-axis. Cell alignment was examined throughout the experiment until a steady state was reached. Before t*, cells spontaneously aligned in the x-direction. After t*, the strength of alignment transiently decreased then increased, and mean cell orientation transitioned from the x-to the y-direction following an exponential time course with a time constant that increased with t*. Collagen fiber orientation exhibited similar trends that could not be explained by passive kinematics alone. Structural realignment resulted in concomitant changes in biaxial tissue mechanical properties. The findings suggest that even highly aligned engineered tissue constructs retain the capacity to remodel in response to altered mechanical stimuli. This may have important functional consequences when an anisotropic engineered tissue designed in vitro is surgically implanted into a mechanically complex graft site.
