[Morphological evaluation of fascia lata tissue implantation for chondral defects in the knee joint of sheep under active motion and load].
Experiments carried out on 64 knees of 32 Lein sheep with superficial and deep chondral defects of the patella and femoral condyles covered by autogenic fascia lata grafts indicate that under active motion and load the grafted tissue after 6 weeks is thinner, fragile and lustreless. Quantitative and qualitative deterioration of collagen fibers, almost complete atrophy of elastic fibers and increase in number of cells and vessels is observed under microscope. After 9 weeks remodeling of the fascia occurs which thickens and increases in number of fascicular collagen fibres, after 12 weeks the foci of neochondrogenesis can be found. After 26 weeks a new hyaline like cartilage is generated surrounded by connective tissue containing fascicular collagen and elastic fibers. At this point remodeling is not yet completed.
