Achilles tendon elongation after acute rupture: is it a problem? A systematic review.
Conclusion: Fair evidence of the influence of tendon elongation in biomechanical parameters was found. In a general population, evidence of a detrimental effect of tendon elongation on PROMs or functional strength at follow-up was not found in this review.
