@nicolas_bermudez. Sorry first chance I've had to answer. 1977 was my first peroneal tendon surgery. I broke my ankle in January 1977.( was 18 )Cast came off 6 weeks later, shortly thereafter the tendon started subluxing. The orthopedic at that time suggested recasting to rest ankle and hopefully the retinaculum would take care of itself. Another 6 weeks or so cast came off no change. Early fall 1977 I had surgery. It lasted until early 2000's. It is working well. I would opt for the surgery as quick as possible. Other than what I've already told you maybe somebody else can shed some light on it. Don't worry about it too much. I guess when it rains it pours after I had surgery the last time I was ready to go back to work. The day I was to go back I got diverticulitis. I was off for another month-and-a- half. Easy to take good health for granted and a whole body until you don't have one.
