I fixed my foot drop with exercise since its a nerve communication problem. Operations will cause more nerve damage. Think about each movement slowly on up/down stair placement. Watch self walking slowly in mirror holding onto parallel bars. Uphill treadmill helped strengthen muscles around knee for lifting. Standing stations for leg strength. Dropping ankles off back of leg press for ankle strength. I practiced slow heel to toe walking and watched in mirror. Used walker for smooth walk and progressed to Hugo cane. 4-Leg canes slow down smooth walking. Check online for handicapped or physically challenged gyms or centers in your area. Had more equipment than the hospital gym. Christopher Reeves Foundation discussed neuroplasticity which is the brain connection to your nerves. Your spine also has a memory that needs to be engaged thru repetition. I took me 6 months to walk again and a 4 months to move to cane. Then drop foot a few more months. Many center s allow PTs to be there to help.

I had foot drop and it was do to my knee. Had orthoscopic surgery to fix it!
