Abstract
- Chondrocytes were harvested from knee joints of immature rabbits and cultured as monolayer until confluence, then split, and grown in collgen gel. The cells were transplanted into osteochondral defect of two different sizes (Group I : 16.1mm2, Group II : 7.1mm2) made on the patellar groove of distal femur in 21 mature rabbits. Left legs were used as experimental group and right leg as control. After 7 weeks, 1 out of 5 in experimental side and none out of 5 in the control side showed cartilaginous repair in Group I and 3 out of 8 in experimental side and 2 out of 8 in control side showed cartilaginous repair in Group II. After 14 weeks, 1 out of 4 in experimental side and none out of 4 in control side showed cartilaginous repair in Group I and 2 out of 4 in experimental side and 2 out of 4 in control side showed cartilaginous repair in Group II.
