3. A
week 4 representative sagittal
section of the patella-patellar tendon junction after injury and training. H&E-stained sections from the AI (A) and PIERT (B) groups
indicated an indistinct cell profile, lowered cell density, and unclear
tidemark, but the CON group (C) presented well-aligned collagen fibres
and a clear tidemark. Polarised microscopy images demonstrated
poorer collagen alignment in the AI group (D) and PIERT group (E) than
in the CON group (F).
