achilles tendon surgery

i badly tore my achilles tendon back in 2011. I had surgery on it to repair it. I have had nothing but problems with it. it freezes up in winter, I can’t walk down stairs properly, can’t squat and walking is very hard over periods of time. My doctor has sent me to another surgeon because she feels like the first surgeon has wrecked it. can I avoid another surgery with physio or will I have to get it redone?
