[Less invasive turn-down flap tendinoplasty in chronic Achilles tendon rupture].

In general, worse results than in percutaneous reconstruction of acute Achilles tendon injuries. Despite this, high degrees of patient satisfaction with a low rate of postsurgical complications and good functional outcome with admittedly poor data availability. Relevant increase of plantar flexion strength depending on the amount of degeneration of the triceps surae muscle.
