Several investigators have proposed an increasing role
for arthroscopy as a definitive treatment. Maiotti and colleagues42
recommended using arthroscopic thermal capsular
shrinkage for chronic ankle instability without ligamentous
repair. Good-to-excellent results were reported in 86% of
patients at 42-month follow-up. In addition, some authors
have reported using a three portal arthroscopic approach
to assist autogenous plantaris tendon reconstruction of the
ATFL and CFL.43 No clinical results were reported and, as
well, this technique is associated with a high level of technical
difficulty.
