Figure 4

Degradation and remodeling of tendon graft fixed by the HP Mg screw and Ti screw.

(a) Representative sections of the tendon-bone interface at three, six and nine weeks after surgery. HE and Mallary stained. G represents the tendon graft, B represents bone, red arrowheads represent defragmented collagen fibers, red pentagram represents the necrosis of collagen fibers and black arrowheads represent Sharpey-like fibers. Bar = 400 μm. (b) Calculated relative area of collagen fiber at the tendon-bone interface. *denotes p < 0.05.
