Correlation between the Coaptation and Regeneration of Tendon Stumps in Endoscopic Assisted Achilles Tendon Rupture Repair.

Although complete regeneration can be finally achieved, the early stage of tendon stump regeneration can be prolonged due to undesirable coaptation when endoscopic Achilles tendon repair technique is applied. The prolonged high signal duration on MRI indicates the less-than-ideal regeneration of the tendon, which might lead to elongation of the tendon.
