Plain-English summary
A group of dogs with medial patella luxation (a condition where the kneecap slips out of place) underwent surgery using a new material made from castor oil instead of traditional grafts. The study compared this new technique to the standard surgical method. While the castor oil polymer did not integrate with the bone as hoped, it was found to be safe and did not cause inflammation. This suggests that the castor oil polymer could be a useful alternative for certain joint surgeries in dogs.

Abstract
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. The dogs were sacrificed after 30 or 90 days and the anathomic peaces were analyzed macro and microscopically. Chi square and Wilcoxon tests were used for the statistic analyses of the results, considering probability of 5%. RESULTS: It was not observed bony integration on the castor oil polymer group. There was resorption of the graft along experimental period and absence of inflammatory cells in the studied periods. CONCLUSION: Castor oil polymer assisted cicatrisation process, was biocompatible without inflammation, and it can be used in joints as an alternative for bony filling.
