Mine was a tear, and I went from May to August before the surgery. My right shoulder was in pretty bad shape by the time I went in. From my elbow on down I had full movement. But to lift my right arm, I had to left it with my left. There was no motion from the right elbow to the shoulder.
The doctor I had specialized in this. I think that is about all he did.
I have a difficult time with any kind of pain killers beyond OTC. I don't recall anything bad, as long as I did not take pain killers. But that result was unrelated to the surgery, other than what they gave me after the surgery.
However, I did develop sciatica so bad I could not get out of bed without literally a 45 minutes head start and a lot of pain.
So I was taking PT for the sciatica and the rotary cuff surgery.

And the sciatica was far worse.
I just did not have any issues post surgery with the rotary cuff.
Did the PT and anything else as instructed.
I did have a lot of popping in that shoulder for probably 4 years. But it did not hurt, and the doc said it was scar tissue breaking up.
But even that went away. I have had no issues what so ever.
At the same time I had the surgery, another Dis-er on the collectors board had gone through it three times.

(He played a lot of baseball or softball.) The third time his arm/shoulder was put into some sort of contraption that made his arm/shoulder completely immobile.
That is the caution afterwards -- don't do anything to screw up your arm again. One of his tears post surgery was weeks later when he just getting dressed.
I did have the full cut, not the laparoscopic. Back then, if they could do laparoscopic the recovery was around 2 weeks, as opposed to 5 - 6 weeks off work.
My scar is probably 2 inches long.
Maybe I was lucky (other than the sciatica). I did really well after the surgery and since.
I do recall the first time at PT the therapist wanted me to move my arm. I thought he was nuts. But part of that was mental as I had not been able to move my arm from the shoulder for months.
However maybe post surgery seemed like a breeze because I was in such bad shape going into it.
