In this study, clinical status and treatment outcomes of 20 dogs, which were referred to Istanbul University, Faculty of Veterinary Medicine, and Department of Surgery with the complaint of forelimb lameness and diagnosed with medial coronoid disease (MCD), were assessed. The diagnosis was made based on radiographic findings in 16 patients, on arthroscopic findings in 2 and on computed tomographic findings in other 2 patients. Arthrotomy aimed at removal of fragmented medial coronoid process and debridement of the surrounding tissues was carried out on a total of 20 elbow joints. Average functional recovery period after arthrotomy was 31 days and postoperative lameness scores on day 30 were "1" and "0" in 8 and 12 cases, respectively. Recovery rates on postoperative day 60 were detected to be moderate, good and very good in 9, 5 and 6 dogs, respectively. In the current study, treatment options were evaluated in the dogs with medial coronoid disease and the outcomes were aimed to be a contribution to veterinary practice.
