Abstract

Focal full-thickness articular cartilage defects are challenging to repair. The purpose of this study was to find a simple, effective 1-step articular cartilage repair method. Because stem cell niches produce a microenvironment for stem cell self-renewal, proliferation, and differentiation, we integrated in situ bone marrow stem cells with an implanted poly(L-lactic-co-glycolic acid) (PLLGA) scaffold. Marrow stem cells grew and proliferated on cell-free PLLGA scaffolds, which were evaluated by scanning electronic microscopy (SEM) and Cell Counting Kit-8 (Dojindo, Kumamoto, Japan). Twenty-seven rabbits (54 knees) with large cylinder femoral trochlear cartilage defects were created and repaired with microfracture and cell-free PLLGA scaffold implantation (group 1), microfracture (group 2), or cell-free PLLGA scaffold implantation (group 3).Outcomes were evaluated by magnetic resonance imaging, International Cartilage Repair Society scores, histology, and immunohistochemistry. The repair effects were better in group 1 than in groups 2 and 3. In group 1, hyaline-like cartilage formed at week 24. Magnetic resonance imaging showed homogeneous signals as the adjacent normal cartilage. Collagen type II and toluidine blue were stained p...Continue Reading
