Fig 3. Biomechanical properties in the articular cartilage in control and α5 CKO mice.

The knee joints were harvested from control and α5 CKO mice 4 weeks after OA surgery (OA surgery) and without surgery (No surgery). The femoral condyle was subjected to AFM-based nanoindentation assessment. The graph represents average and SE, n = 5/group. Eind, Effective indentation module calculated from Hertz model.
