Sartorius muscle proximal release to repair grades III and IV medial patellar luxation in dogs

Six surgical corrections were performed with techniques of bone and soft tissue reconstruction, according to the individual presentation of each patient, in four Toy breed dogs, which had grades III and IV luxation, two of them bilaterally operated. During the recovery excessive medial tension associated to the Sartorius muscle was detected, which motivated its release at the iliac insertion. The animals had a functional recovery of the limb after 15 days, and complications or loss of function related to the release of the Sartorius muscle were not observed even after six months. It is believed that the proximal disinsertion of this muscle can be necessary and effective in some patients as a complementary technique to release medial tension in dogs with grades III and IV medial patellar luxation.
