Abstract

The aim of this study was to analyse a series of five cases of early surgical treatment in juvenile canine patients with high-grade medial patellar luxation. Canine patients, with immature skeleton, affected by grade III or IV medial patellar luxation and treated by multimodal surgical techniques were selected. Five dogs of different breeds, mean age 7.2 ± 3.0 months, met the inclusion criteria. Simultaneous distal femoral varus and external tibial torsion were identified in three of the five cases, whereas in the others, femoral varus with associated tibial valgus and isolated external tibial torsion were observed. Four of the five patients were treated surgically with closing wedge osteotomy of the distal femur, and three of them underwent tibial tuberosity transposition simultaneously. Only two animals required trochleoplasty. Mean time to beginning of weight bearing was 9.8 ± 5.5 days, whereas time to bone healing was 55 ± 24 days. Bone realignment of the extensor apparatus and return to limb support were achieved in all cases. Postoperative reintervention was needed in one patient; however, it was not linked to the initial surgery. Patients were followed up to 1 year postoperatively, with maintenance of extensor alignment and no late complications. The early surgical approach has been shown to be effective in the definitive treatment of juvenile dogs affected by high-grade medial patellar luxation.
