The medial patellar luxation is an orthopedic disorder frequently seen in veterinary practice, affecting mainly small dogs. It is characterized by the medial displacement of the patella from its normal position in the trochlear groove, and surgical treatment is recommended from grade two dislocation. The objective of this study was to test if the creation of a complementary patellar ligament, manufactured from shredding of surplus retinaculum is a good technique to reinforce the patellar stabilization for the treatment of medial patellar luxation in dogs. We used 16 knees of 13 dogs, regardless of gender or age who had medial patellar luxation grades two, three and four, and among these, 8 were part of the B group in which we used the technique of synthetic patellar ligament for comparison. The animals were evaluated 30 and 90 days after surgery, for the parameters of pain, willingness to lift the contralateral limb, lameness and weight-bearing on the affected limb by the nonparametric Wilcoxon test for differences between ordered pairs. Since all animals showed functional recovery in 90 days, it is concluded that the proposed technique is also an appropriate surgical option for the strengthening of patellar stabilization in the treatment of medial patellar luxation in dogs.
