Historical review and present status of free fat graft autotransplantation in plastic and reconstructive surgery.
Billings E,James W. May +1 more
TL;DR: Investigations of the various uses of free fat autotransplantation in animals and humans provide an understanding of the problems associated with the use of fat as a free graft and evidence of the dynamic nature of adipose tissue that strongly supports the cell survival theory and gives explanation to the unpredictable behavior of freefat autografts.

Gait parameters following stroke: a practical assessment.
TL;DR: General gait parameters improved over time, with the largest changes occurring in the first 12 months, however, the percentage of time spent in double and single limb support, stance and swing, parameters which describe the asymmetrical pattern of gait, did not change over time.
Cartilage resurfacing of the rabbit knee. The use of an allogeneic demineralized bone matrix-autogeneic perichondrium composite implant.
TL;DR: It is concluded that demineralized bone matrix used as a subchondral matrix in a cartilage repair model 1) stimulates and induces sub chondral bone ingrowth, 2) provides a surface on which cartilage Repair can proceed, and 3) can be utilized as a platform on which perichondrium can be fixed to provide a cellular source forcartilage repair.

The changes in intramuscular pressure and femoral vein flow with continuous passive motion, pneumatic compressive stockings, and leg manipulations.
TL;DR: Overall, passive straight-leg elevation produced the largest flow (1524 ml per minute), followed by the anatomic CPM and nonanatomic CPM, and then by active ankle dorsiflexion, pneumatic stocking inflation, manual calf compression, and passive dorsifLexion.

TL;DR: In this paper, a full-thickness articular-cartilage defect was created in the medial femoral condyles of 32 adult rabbits and the defects were filled with demineralized bone or a composite of demined bone and perichondrium.
