Project Description

The purpose of this animation is to teach major steps of an operative technique (osteochondral autologous transplantation surgery – OATS) for surgical management of capitellar osteochondritis dissecans (OCD). OCD of the capitellum is most commonly seen in young athletes from overuse of the elbow. For developing adolescents, OATS is an increasingly popular method of preserving articular congruity and joint stability because it replaces diseased tissue of the capitellum with healthy tissue from a donor site (lateral femoral condyle). In the operating room, the procedure is extremely difficult to observe or capture with a camera as the opening incision is very small. The 3D surgical models were created to be particularly helpful for use in teaching presentations for orthopedic residents and surgeons. The animation has been used in conjunction with surgical footage to enhance teaching and learning of operative techniques for treating OCD in young athletes. This animation is an edited portion of a longer teaching video to be published online along with surgical video footage and recorded narration. For the purposes of this submission, additional text was added to replace the voice recording and the video highlights the three major portions of OATS: recipient site preparation, donor grafting, and graft placement.
