Yo
I scrubbed in on a laproscopic labrum tear repair on friday. I am only telling you what I was told, and saw with my own eyes.
3 incisions were made, got the scope in the posterior incision, tools in the anteriors. visualized the labrum, made 3 repairs, (basically glorified slipknots/hangmans knots on the oppposing labrum fragments). Then turned our attention to the posterior aspect for one more approximation in the posterior labrum. The reason for the last one is that there is some posterior instability in anterior tears.
Factors to consider: How long you have been dealing with this. If recent, then your chances of a recurrence are lower than a Px who has been neglecting care for a year. The reason this is true is that the opposing labrum fragments become more damaged, and "floppy" over time if not repaired. This results in a decreased ability to hold the sutures.
The whole procedure took a little less than 2 hours, and the patient was then put into a sling.
Realize, that you may never have the full functionality of a normal labrum, but at least your shoulder won't pop out of place when you roll over at night. Thats all I know.
Peace.
