Up to 20% of patients with an ankle sprain may develop chronic lateral ankle instability (CLAI), potentially necessitating surgery like the Brostrom-Gould technique (BGT).
A study of 79 non-athlete patients showed significant improvements in function post-surgery, with AOFAS scores rising from 64.6 to 97.2, and 77.2% returning to their preinjury sports activities.
Despite these improvements, some patients experienced residual pain and symptoms of instability, which affected their ability to engage fully in physical activities.
