This is a retrospective study describing postoperative complication encountered with surgery performed indogs with medial patellar luxation (MPL). During the 4-year period, 77 operations had been performed in 66 dogsfor correction of MPL. The patients were surgically treated with medial soft tissue release, lateral soft tissue tightening,trochlear block recession, and/or tibial tuberosity transposition (TTT). Their prognoses were periodically evaluated for6 months postoperatively. The failure rate was higher in revision surgery than in the first surgery, and the most commonpostoperative complication was migration of the tibial tuberosity fragment. The causes for the migration of the tibialtuberosity fragment were identified as the downward insertion of a surgical pin, the eccentric position of an insertedpin in the tibial tuberosity fragment, and blunt angle formation of the tibial tuberosity. It is suggested that the appropriatemethods for TTT could minimize complications and lead to a good prognosis.
