The dynamic modulus of the normal or mildly degenerated cartilage correlated negatively with the Mankin score: r (Spearman) = −0.823, n = 348. All visually degenerated samples were softer (dynamic modulus <
2.9 Mpa) than the visually and histologically normal samples (dynamic modulus = 14.7 + 2.9 MPa). Stiffness at the repaired site was similar to normal cartilage at adjacent sites in the knee.
