I wish I could say for sure, but so much depends on the level of damage that is done already, what the cause is, the surgeons skill, whether your body produces excess scar tissue or not , good PT and followup care....

My time frame suggestion was for return to most daily activities of life after an important surgery like this.
{doesn't always include return to work - depending on the job.}

It's just hard to say for sure either way..
