Figure 6. Illustration of the enthesis scaffold from macro- to nano-scale. (A–C) Full-size scaffold regions. (D, F) SEM and (E) optical microscope (20x
magnification) images highlighting the microscopic structure. Scale bar length: (D–F) 500 µm. (G–I) SEM images of the scaffold at the micro- and nano-
scale. Scale bar lengths: (H, I) 200 µm and (G) 20 µm.

Figure 7. Uniaxial tensile test results. (A–C)Three different moments illustrating a sample of enthesis scaffold during a tensile test. (C) Failure occurs in the
central part of the PLGA region. (D) Characteristic stress–strain curve of the enthesis scaffold.
