Repair of large full-thickness articular cartilage defects in the rabbit: THE EFFECTS OF JOINT DISTRACTION AND AUTOLOGOUS BONE-MARROW-DERIVED MESENCHYMAL CELL TRANSPLANTATION
2005
We produced large full-thickness articular cartilage defects in 33 rabbits in order to evaluate the effect of joint distraction and autologous culture-expanded bone-marrow-derived mesenchymal cell transplantation (ACBMT) at 12 weeks. After fixing the knee on a hinged external fixator, we resected the entire surface of the tibial plateau. We studied three groups: 1) with and without joint distraction; 2) with joint distraction and collagen gel, and 3) with joint distraction and ACBMT and collagen gel. The histological scores were significantly higher in the groups with ACBMT collagen gel (p
