Summary

This study looked at two surgical techniques to treat chronic ankle instability—a condition where the ankle gives way repeatedly after a sprain. Researchers compared a newer keyhole (arthroscopic) method with the traditional open surgery in 41 adults. The goal was to see which approach leads to better function and less pain six months after surgery.
