Use of castor oil polyurethane in an alternative technique for medial patella surgical correction in dogs.

Purpose: Comparative morphologic study of utilization of castor oil polymer in dogs joints, as an alternative technique to autogenous graft, in surgical correction of medial patella luxation.

Methods: Twelve adult dogs, of both sexes, were randomly allocated to two different groups of six animals each. Group I (biopolymer) consisted of the deepening of the right femoral troclea, with the implantation of the biopolymer prothesis, and compared to group II (control) which consisted of the conventional trocleoplastia technique with wedged cut of the left femoral troclea.
