PTA (n = 6) and NH (n = 6) repairs both exceeded the peak in vivo force required for activities of daily living (100 N; in vivo force and displacement, IVF and IVD, respectively) [,]. However, PTA and NH repairs do not match the normal central-third PT (Normal; n = 8 [,]) or TEC (n = 7 []) repair curves.

Insertion site images are shown with H&E staining and immunohistochemical staining for type II collagen (Col2). After 12 weeks of healing, proper insertion sites were not regenerated by PTA or NH. The insertion sites in the native struts (NS) appear unaffected by the surgical procedure. H&E images are labeled to reflect: B, bone; T, tendon; FS, fibrous scar; MFC/FC, mineralized fibrocartilage/fibrocartilage zones of the insertion site, respectively (note: these zones are not as distinct in the patella as they are in the tibia); areas resembling neo-vascularization are marked with an asterisk. Scale bar = 200 μm.
