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

Abstract

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.
