A serious injury to aging tendons often means a slower, less complete recovery – one that science is still trying to fully understand.
Researchers used a preclinical model of aging to investigate how two key proteins, decorin and biglycan, influence tendon healing. Using a controlled knockdown approach, they assessed structural, genetic, and mechanical outcomes across early and late healing stages. They found:
🔹 When removed early, decorin knockdown appeared to improve recovery of viscoelastic properties.
🔹 Biglycan deficiency delayed initial healing but didn’t impair final mechanical strength.
🔹 Collagen fibril architecture changed, yet quasi-static strength measures were unaffected.
These findings suggest subtle, protein-level interventions may help aged tendons heal smarter, not just stronger.
