Arthroscopic Assisted Surgical Technique of Impaction Bone Grafting and Autologous Matrix‐Induced Chondrogenesis for Deep Osteochondral Knee Defects

Osteochondral knee defects typically affect young, active patients, altering knee biomechanics and eventually leading to joint degeneration. There are several treatment methods; one less expensive and potentially effective option is the combination of autologous impaction bone grafting with autologous matrix-induced chondrogenesis (BG-AMIC). BG-AMIC is a safe and effective treatment for deep knee osteochondral lesions, with a statistically significant and clinically relevant improvement in patient-reported outcomes. We describe a single-stage, safe, and efficient approach whose efficacy has already been proven.
