Diffuse Host Bone Marrow Edema on SixMonth MRI Predicts Osteochondral Allograft Failure

Video Transcription

Video Summary

Dr. Guilherme Palares presented a study on using six-month MRI to predict osteochondral allograft (OCA) failure by measuring host bone marrow edema (BME). In 56 patients, those with BME volume over 10 cm³ had a 50% failure rate within three years, while those under 10 cm³ showed 100% graft survival. BME volume was assessed via MRI and correlated with outcomes like graft collapse or revision surgery. The study suggests that prolonged diffuse BME reflects immune response and indicates higher failure risk, making BME measurement valuable for patient counseling and early intervention after OCA transplantation.
