Among ligament types, VLC instantaneous (12.55 ± 1.19 MPa) and relaxed moduli (8.89 ± 1.48 MPa) were higher than the DRL (instantaneous: 7.03 ± 4.17 MPa, P = 0.006; relaxed: 4.51 ± 3.13 MPa, P = 0.003) and POL (instantaneous: 7.86 ± 2.67 MPa, P = 0.05; relaxed: 5.02 ± 2.15 MPa, P = 0.025) in the elder healthy/early-stage OA group., Additionally, a weak trend showed that VLC had a higher Young’s modulus at 20% strain (26.36 ± 4.20 MPa) than that of DRL (17.60 ± 8.69 MPa, P = 0.089) and POL (16.16 ± 5.33 MPa, P = 0.089) in the elder healthy/early-stage OA group.
