Brostrom44 first described a mid-substance repair of the
ATFL and CFL in 1966 after reporting on a series of 60
patients (Fig. 4A). Gould and coworkers45 further modified
the Brostrom procedure by reinforcing the repair using the
lateral talocalcaneal ligament, CFL, and inferior extensor
retinaculum, which helped limit inversion and corrected
subtalar instability (Fig. 4B). Karlsson and associates46 were
the first to report on imbricating the damaged ligaments and
reinserting the ligaments through drill holes in the fibula
(Fig. 4C). They noted improved results using this bone tunnel
repair of the ATFL and CFL
