Treatment of Osteochondritis Dissecans of the Knee with Autologous Iliac Bone Graft and Hyaluronic Acid Scaffold

Abstract

Osteochondritis dissecans (OCD) is a condition that corresponds to an idiopathic focal lesion affecting the subchondral bone with possible compromise of the stability of the adjacent cartilage. Treatment depends on the size of the lesion, cartilage stability, and the physeal status. The case reported is about an 18-year-old male patient who complained of suffering from knee pain for a period of ten months. Magnetic resonance imaging (MRI) revealed a lesion of 2 cm² in the medial femoral condyle that compromised the subchondral bone, compatible with OCD. He underwent surgery that consisted of filling the subchonral defect with an iliac crest autograft and sealing the defect with a hyaluronic acid scaffold. At the 12-month follow-up, the MRI shows complete healing and the patient has resumed sports activities. Management with autologous iliac crest graft and hyaluronic acid scaffold represents an effective alternative treatment for OCD.
