title: [Texture of cruciate ligaments as a modifying factors of grafts].
abstract: In the last ten years hundreds of alloplastic prostheses of cruciate ligaments of knee (ACL) have been implanted. The remote results after surgeries of this kind were univocally bad. All the known synthetic fibres undergo the process of aging and of constant decrease of their mechanical properties. Research of graft fulfilling the conditions of resistance ACL and investigations over the ways of delaying its degradation are continued. The author investigated 5 kinds of polyester prostheses ACL made of homogeneous polyester fibres with the same mechanical properties only with different texture. To estimate biocompatibility he implanted them to piglets weighing 20-30 kg and to rabbits into dorsum muscles in the place of the cut out ACL. After 3 and 6 months a section of the piglets was made estimating the macroscopic, histological and radiological picture. For the rabbits a section was made after 14 days and 3 months. The investigations confirmed a high biocompatibility of the grafts. Large differences in hypertrophy of particular grafts with fibrous tissue were noticed.
