A New Generation of Osteochondral Autograft Transfer System for the Treatment of Osteochondritis Dissecans of the Femoral Condyle: Clinical Experience in 18 DogsFunding None.
Objectives The aim of this study was to describe the clinical application and outcome of osteochondral autograft transfer using the COR system (COR; DePuy Synthes, Warsaw, Indiana, United States) for the treatment of osteochondritis dissecans (OCD) of the femoral condyle in dogs.
Methods Medical records of dogs that were treated for OCD of the femoral condyle using the COR system between February 2013 and March 2020 were retrospectively reviewed. The results of pre- and postoperative clinical and radiographic examinations were evaluated.
Results Twenty stifles (18 dogs; 15 lateral and 5 medial femoral condyles) met the inclusion criteria. A single graft transfer was done in six stifle joints and mosaicplasty in 14 (2 grafts in 9/14 stifles; 3 grafts in 5/14 stifles). Proper anatomic reconstruction was confirmed intraoperatively and radiographically in all dogs. There were no major and three minor postoperative complications. At 3 months, 15 of 20 stifles (14 of 18 dogs) had no lameness or radiographic signs of inflammation. At 6 months, 12 of 13 dogs had no lameness or discomfort, and four of 13 stifles had radiographic evidence of moderate osteoarthritis.
Clinical Significance Treatment of OCD of the femoral condyle using the COR system is feasible in dogs, with low complications and provides a satisfactory short-term outcome.
