David Fermer won a bronze medal on his comeback to major competition at the Salisbury Open.
Fermer was sidelined for two years after almost losing both legs in a road accident.
But the former British junior champion is confident he can get back to his best after his success in the 66kg event in Wiltshire.
Fermer, 20, from the Joff (Peacehaven) club, said: "It was nice to get back into competition.
"I could have done even better than a bronze medal but I've got to be happy with the result.
"I felt fine physically apart from lacking a bit of the strength I used to have but I am sure I'll get that back.
"A lot has happened to me over the past couple of years but I was okay psychologically.
"The Salisbury event has underlined my belief that I can get back to what I was and move on and try and get to the Olympics one day."
Fermer, in a recent interview with The Argus, told how he snapped the femur bone in both legs after falling off a bike while on holiday in Greece.
His first instinct was to delay treatment until he returned home. He said: "If I had taken that flight, I would be dead. I'd have died on route because I'd have developed deep vein thrombosis."
