Articular Cartilage Repair Using Marrow Stimulation Augmented with a Viable Chondral Allograft: 9-Month Postoperative Histological Evaluation

Figure 7

Histological stains after marrow stimulation. Histological stains of cartilage repair tissue collected from 43-year-old patient 8.2 months after marrow stimulation surgery that required revision. Section outlined in blue in H&E stain is fibrocartilage, while the remaining tissue is primarily hyaline-like cartilage. Scale bars = 500 m.
