  • The results of the three treatment groups - bending, shear, and combination - are compared with those of the control group and native knee joint. The three treatment groups approximate the 80:20 bone to cartilage ratio found in the knee joint, while the mean control group ratio of bone to cartilage is 94:6. The mean intervertebral joint ratio of bone to cartilage is 50:50.
