RESUMO
Tendon surgery should be based upon an understanding of tendon healing mechanisms and the fate of tendon grafts. It is also essential to understand those factors that produce adhesions to tendons and how to avoid or minimize such adhesions.

Acellular freeze-dried canine profundus tendon allografts were placed in the knee joints of dogs and later harvested at 2, 3, and 6 weeks. All allografts remained intact, free swimming, and free of adhesions; all were covered by a layer of proliferating fibroblast-like cells that "healed" cuts made in the allografts, rounded off their previously squared-off ends, and recellularized them. The cell source for the phenomena was the synovial cell of the joint, a highly versatile, facultative fibroblast. An intrinsic capacity of flexor tendons to heal themselves cannot be critically tested by fallaciously considering synovial cavities "tissue cultures in situ," as some investigators have claimed.

We advise a simple solution to the problem of the bulging and ptotoic lacrimal gland in a blepharoplasty. A pocket is dissected above and behind the gland, and the gland is fixed there to the orbital periosteum. This technique safely produces a normal contour in the lateral third of the upper eyelid, where a bulge has been present before.
