Ultrastructure evaluation of meniscus tissue. The whole (A), outer (B) and inner (C) regions of native rabbit meniscus. The fibrochondrocyte (white arrow) was seen in some lacunas (D). Menisci of the Xeno group (E,F) and the Allo group (G,H) at postoperative 1 year, and some integrated cells (white arrow) were also seen. The cell incorporation were observed only at the upper and lower surface and the inner 1/3 part of the new regenerated meniscus in the Xeno group while most of the cell infiltration concentrated in the outer 1/3 part of the graft in the Allo group.
