Pearls and Pitfalls

Pearls	Pitfalls
Ultrasonographic localization of the sural nerve to secure endoscopic portals and the percutaneous suture.	Sural nerve identification could be difficult and has a steep learning curve.
Endoscopic portals in front of the gap between tendon ends after ultrasonographic localization.	Poor tendon capture by misplacement of the percutaneous needle through the proximal and distal ends.
Minimal endoscopic debridement of the tendons ends (avoiding the paratenon to enhance healing).	Contraindicated in case of chronic tear (3 weeks).
Endoscopic control of the needle passing through the proximal and distal tendon ends.
Transillumination sign loss after pulling and reducing the gap of the rupture,
