  1. Tendons and Ligaments • Tendons-muscle to bone • Ligaments-bone to bone

  2. Collagen (E~600 MPa, fails at 4% strain

  3. Tendon (load-deform. curve

  4. Biology of stress/strain curve

  5. Reconstruction of Ligaments

  6. Reconstruction--OA 100 patients- 53 okay, 34 mild OA, 12 moderate OA, 1 severe OA

  7. Hooke’s Law??? NO • When can we use Hooke’s Law (σ=Eε) • Linear elastic • Strain proportional to stress • Instantaneous response • Perfect storage of energy
