Foot drop surgery.?

Probably notthe best place to come but the internet is a wonderful place so here it goes.

A few years back roughly 4/5 years I broke my hip and stretched the nerve in my leg which caused me to have a foot drop and need a splint to help me walk.

Doing a little digging around and it turns out there is a surgery procedure that could help so I wouldn't need to have a splint. Well I was thinking about the surgery and i was wondering what it would of a actually help. Like would I get a full use of my foot again. Etc
