The use of interference screws in the reconstruction of the anterior cruciate ligament has increased over the years. Despite doubtless advantages there are some problems, too, some involving method of fixation, others the metallic nature of the screws. With the purpose of overcoming the latter, the authors evaluated the possibility of using interference screws made of bioabsorbable material. This preliminary study was conducted on two animal models (bovine and ovine); as a comparison parameter the torsional pair of screw insertion was used. A substantial similarity in the results thus obtained was observed that, together with the minor difficulties observed in the surgical field, contributes to the indication of the ovine model as preferential, based also on successive tests of functional validation conducted in vivo.
