Comparison was made between the behaviour of fresh autogenous grafts of rabbit tendon and that of homogenous grafts inserted after the graft had been preserved for approximately one week, either in ethanol or merthiolate or by lyophilisation.

Regardless of the method of transplantation or preservation, a viable tendon-like structure of compact connective tissue bundles longitudinally oriented was eventually present at the sites of the grafts, with ingrowth of fibroblasts and capillaries from host to graft. The period between transplantation and recognisable viability of the grafts varied from less than one week for the autogenous transplants, to from three to five weeks for the preserved grafts.

Either autogenous or homogenous grafts will take in rabbits.
