Abstract |
Objective To evaluate the effects of proliferant by injecting blood into the articular cartilage defect. Method The patella of rabbits were dislocated laterally and 2 mm circular and 2 mm depth full-thickness defect was made in the articular cartilage. We injected 0.2 cc autologous blood to the right defect and normal saline to the left one at 1 week after operation for six times with a 1 week interval. After injection for six weeks, the articular cartilage defect were obtained and stained with H-E and S-100. Results The surface of the saline-injected group was easily distinguishable from the surrounding articular cartilage. But the blood-injected group had similar appearance to the surrounding cartilage, with the margin of the defect barely discerptible. Strong S-100 stained immune cartilage cells were observed in the blood-injected group. Conclusion The repairing process of the injured articular cartilage using autologous blood was shown to be much better than that of saline-injected group although the observation period was short and the number of animal was small. So we found that autologous blood effectively repaired osteochondral defects. (J Korean Acad Rehab Med 2005; 29: 406-412) |
